Smog Star Express - Pulled straight in - Smog Check Stations Near Me - Concord, California

Buyer beware, I took my Honda to this location without realizing I had a check engine light on from the day before. The tech had me drive into the shop bay and park. I walked away, and within 12 minutes, he called for me to pay. He stated the car failed. I remembered the check engine light was on from yesterday. Initially, he quoted me a price of $70.75. When I questioned this, he insisted that was their standard charge. I was surprised because they had only charged me $55.00 three months ago. He asked where I had gotten that price as if he were fishing for information to see if I had found it online. When I told him about the previous charge, he removed $15.00 from the total, bringing it down to $55.00 for a failed smog test. I take responsibility for bringing my car in with the check engine light on, but I can't understand why the technician didn't mention it when he checked the mileage; it was indicated on the dashboard. Instead, he just took my money. I called another shop, and they informed me that if a car fails the smog test, they only charge half the price, and then if the vehicle is repaired, you can come back for a second smog test and pay the remaining amount. This shop was more focused on making money than on providing good service. Be wary--the shop took my $55.00 and then wanted to charge me another $40.00 for a re-smog test, totaling $95.00. What a rip-off! When I tried to discuss this with him, I felt like my concerns were not taken seriously. Word to the wise: call around and ask about their policies regarding failed smog tests and re-testing fees before committing. read more

Smog Star Express - Time for my 2005 SUV smog test - Smog Check Stations Near Me - Concord, California

The smog tech Christopher plugged the OBD scan tool in the car 2 minutes later told me it would not pass. I said what's wrong the car only has 30k miles on it. he said bring it back after driving it 100 miles. then said that will be 40 bucks. I said then free retest when I bring it back he said abruptly,,,, NO it will be another 40 plus. so much for 2 minutes for an easy check. as I just prior to that replaced a new battery in the car a couple days before that. which ended up being the problem because the computer needs to reset before smog testing. Hey Christopher cocky attitude for a 2 minute smog check I will not return here again as I had used them in the past. no more . go to Bayside smog if you want an honest fair smog done. also keeping customers outside of the building so they don't hear of the coupon discount when paying inside. read more

Made an appointment with Smog Star. I was in and out in less than a half an hour. I recommend

This place SUCKS!! I brought my truck in for a smog check. The "tech" said it failed. Charged me $40! I took it to another smog shop it passed. WTF!! read more

I walked in and was greeted not to long after by Chris. Told him that I needed a smog check for the DMV and he said that he would come and get me when it was my turn. I told him I was in a silver Nissan and sat in my car and waited. I probably waited about 15 minutes before he called me over to pull my car into the garage. Once my car was in, it took about seven minutes for the job to get completed. I was surprised how fast it was, which I highly appreciated as I needed to head back to the DMV afterwards. Before Chris started service he kindly grabbed a few seats, cleaned them off for me and I was able to sit in the little grassy area they provide. I appreciate Chris's customer care and I will definitely recommend this spot to others. He was a one man show but he got the job done efficiently, thank you Chris! I recommend checking in, there's a little surprise if you do read more

Super fast and efficient. I was done in 10 minutes with an appointment which was easy to make. I highly recommend them.

awesome service! Chris was very efficient and did my Smog Check very quickly. I would highly recommend the Smog Star Express.

Equipment not functioning upon opening business and my 8:30 am appt....a bit of an inconvenience, since I had made an app t, I was able to use another service within 3 miles, so that aspect worked out for me to smog my vehicle. Night prior to my appt. SSE e-mailed to remind me...ahhh..after the non-functioning equipment issue and my receiving service at another ...I receive a 'Thank you' for doing business with SSE and hope I 'enjoyed their complimentary beverages and snacks while I waited' I visited the website....no way a rat could find a crumb of who to contact via e-mail or chat. Phone listed is for the technician at the location...no good hollywood, owner seems to enjoy a facade of providing exemplary customer service ...from behind a send only web page. I find the process a bit laughable, as owner is idgas attitude, or clueless to issues of auto e-mails and due to Yelps positive feedback. read more

The customer service is great and it went really quick. Convient and local and reasonable price with coupon

NOT recommended. Terrible experience here- poor service, dangerous health practices, disregarded appointment times, and possibly a touch of sexist discrimination. I made an appointment online and arrived 5 minutes early. The place was busy and several people were ahead of me. I went into the tiny office, and after a few minutes, the main tech came in to speak with me- NOT wearing a mask (and with no mask in sight). I was told I'd have to wait, and would be served after the other people already waiting in line. Although I was a bit frustrated that my appointment time was disregarded, I decided to stick around anyway. It was about 20 minutes past my appointment time, and a male customer in a nice car pulled in and started talking to the main tech (who was still maskless). Right away, the main tech let him cut the rest of us waiting in line (women, with appointments), with zero explanation or apology. The male customer started receiving service right away. So I left- and will be going elsewhere for all future smog checks. read more

Did what they said & I passed BUT I was "passed up" for a person behind me (I scheduled an appointment) who didn't have an appointment. She was nice & apologized for getting bumped ahead of me but it's not her fault. If you go, send a chick... read more

Don't go there! We brought all of our cars here to get smog whenever it's due. Been going there for roughly 5 years. Every time we went there, the guy who used to work there was very nice and welcoming. This time when we go there, the guy was very rude. Doesn't feel like he wants to work or want our business. The whole time he was like just chill outside. We have no problem to wait but at least let us know how long is the wait. So, we waited for like almost an hour. When it's our turn, he was like I can't pass your smog since your car is too low. I mean we never have any problem with the car being lowered. His only explanation was I can't visually see the second O2 sensor which is very odd. Waste of time and was treated badly. Go to BaysideSmog instead everyone. It's only 5 minutes away from this awful place. It's not the same anymore. At least the technician is not the same guy. read more

Highly recommend!! Customer service is great and they have a shaded area for customers to sit!!

I was searching Yelp for Star Smog on a Sunday as I needed to get my vehicle completed. I found this location near proximity to where I lived in Concord so decided to check it out. I first searched for an online appointment to book through their website, but did not find one. I then tried to call 2times and phone was disconnected. So I figured let me drive over to give them a chance, it was around 9:30am and from visual I already seen one car in the garage and about 3-4people waiting in their cars outside. I already knew it would be busy, but all I wanted was an estimate if today was full, or if coming back later would be best? I walk into the garage the young guy barely looks at me and then I walk closer he asked - wait outside I'll be with you in a second. I proceeded to ask "is it best I come back for an appointment, but he didn't let me ask and took off his EarPods and brushed me off again and said I'll be with you in a second, wait outside" I understand he seemed overwhelmed so early on, but it takes a few minutes to acknowledge and let someone know if it will be available for service today, tomorrow, or how to communicate service being that there was no online or phone to ask for appointments. I am basing this review solely on the customer service and interaction with this gentleman and because of that I will not come back! I wasn't trying to cut in line I just wanted to be treated as a possible customer with respect. I get it he was busy, we all are, so I left and the impression he gave me lead me here with this review. read more

It's almost 40min after opening and no one's here. Also, the voicemail it full and there's no recording to let you know if the hours match what's on the website, let alone what the business even is. Are you really open at 9? Did you go out of business? I hope not, this if my favorite smog place. If no one's here by 9, I'll have to go find somewhere else cause I got stuff to do. read more

Smog Star Express - Waiting area - Smog Check Stations Near Me - Concord, California

It's Official; Smog Star Express is now my go-to smog station! To say painless would literally be an understatement. This place is incredible! I can walk in without an appointment and the smog test usually takes less than 20 minutes! They usually have a special promotion or discount going on, so my service ends up being cheaper than what's advertised. The staff is always friendly and courteous. The waiting area is pretty comfortable and you can help yourself to a complementary soda while you're waiting. Their price list is clearly shown on multiple areas of their back wall. I love that they can electronically send my results directly to the DMV without me even having to lift a finger! I recently learned that they can also do select DMV registration services such as new registrations, renewals, and title transfers. Thank you Smog Star Express for continuing to do honest and excellent work. I'll be seeing you again in another two years! read more

I've never seen my mechanic so angry before! I took my car in to Smog Star to get Smogged. The young kid there gave me a "fail" on my Smog test because of the "Bulb test" (my check engine light was on), swiped my credit card, and told me to take it to my mechanic and come back after. When my mechanic saw the check engine light on, he said, "You mean they saw your engine light was on and charged your card anyway?! They shouldn't have tested your car and taken your money once they saw that light. Don't go back to that place." He confirmed my suspicion that these people are nothing more than 'card swipers'. They exist for no other reason but to swipe credit cards for that easy money. An honest place would've recommended I address the 'light" issue FIRST before testing & charging my credit card. These people are crooked! read more

I arrived 10 mins early of my 100 pm appt. I finally pulled into testing bat at 1:30. The interaction with tech was short, abrupt, and seemed annoyed that he had to deal with customer. THEN i made the mistake of walking into the office in hopes of finding AC. Oh my...he then became agitated and full of energy as he berated me for walking past cones in front door,( like i observed previous customer) and that i must wait outside. ( it was 90+ and i am 80yrs-dealing with heat is difficult). How they call themselves 5 star rated is a mystery to me. Bottom line, uf it is hot outside and you are in a time schedule, go elsewhere. read more

I came to get my car smogged, the person who assisted us seemed a little rude and short with us. When someone else came after us the guy took the time to talk with another customer but told us to wait. Our smog didn't pass which was odd because the car has no issues at all. After the failed smog I took my car to get checked out & mechanic said there isn't anything wrong with the car and was confused to why it didn't pass smog. The guy from the smog place never even told us why it didn't pass. I feel like we were scammed, especially for how much we paid. I took my car somewhere else, better service and it passed. read more

They were very quick with getting me in and out. The employee was courteous and professional. Prices were fair based on the competition. They have socially distanced seating outside and the service technician was wearing a mask the whole time. Would definitely recommend and come back. . read more

Smog Star Express - Getting a smog check - Smog Check Stations Near Me - Concord, California

We had an appointment, but since the gentleman was the only person working, he gave us a double discount since we had to wait longer than expected. He was very nice and he was a fast worker - not too long of a wait. Very good customer service! read more

I had an appointment on 6-8-24 at 10:40am. The guy took two other cars before my appointment. Looks like, it's first come first served, your appointment system is not valid. I left and got service elsewhere. read more

Careless, dishonest, apathetic & insulting is the best way I can describe my experience- then I was called a liar. Here's what happened: I went to get a car smogged that belongs to an elderly family member & hadn't been driven for over 2 years during the height of COVID. I informed the technician before he tested the car that the battery had just been replaced earlier that day & that I had driven the car around for about 20 minutes, about 5 miles or so, to make sure it was up to proper operating temp & that I could see that it was running smoothly before I brought it in for testing. I asked him if he thought that was sufficient and he said absolutely. He completed the test & informed me that it had failed- not because of the actual emissions- that was all good- it was because the car needed to have enough of a history in the computer to show that there were not faults that had occurred within the last 100 miles or so. He then said that there was no way the car could have passed the test since I didn't have at least 100 miles logged on it since the history started over when the battery was replaced. I asked him why he hadn't explained that when I had just informed him that the battery had been replaced earlier that day asked him if he saw any red flags before we moved forward & he just shrugged his shoulders. I said I thought he should retest it at no charge once I had logged the 100 miles, as I had already paid him for the test and he knew it wasn't going to pass before he had even started testing it. He then informed me that it would cost me all over again when I came back since 'they don't do it that way'. *Handy tip for those considering this smog station- many other smog testers DO retest one time for free if you don't pass the first time around. Call around and you will see. A bit frustrated, I decided I would move on with logging the 100 miles & then return to take another shot at pleading my case. When I returned, I began to explain the situation to the (different) technician that was there, who interrupted me immediately saying that they "would never have ADMITTED that it would not have passed the test in the first place, because they wouldn't risk having to do a retest'. To this I replied that I certainly wasn't making up their technician said. He then said that I was making it up and that I was a liar. I told him I was insulted that he called me a liar and he asked me what I was going to do about it. Really? This is who they have working with the general public? Someone who's social skills are limited to apathetic hostility? I told him that because of the way he had just treated me I would be sharing it on Yelp & be contacting the store owner. He replied that he didn't care what I did & that they have plenty of customers. Overall a terrible and completely avoidable experience that left me $80 poorer with nothing to show for it and having to deal with someone who behaved like they were raised in prison. My impression was that their agenda is limited to bringing in cash without letting inconveniences like morals, ethics or running an honest business get in the way to slow things down. One last thing- their prices are higher than many of their competitors. The 76 station down the street is $20 cheaper & open on Saturday- and they are professional and operate with ethics. I originally went to this shop because it was open late on a weekend & I hadn't had an opportunity to schedule an appointment in advance due to the whole situation falling into my lap at the last minute. Never again. read more

Great fast service. No appointment needed! I'd recommend them for your car. Outdoor seating is nice too.

Showed up at 2:45pm with 2 cars in the service bay and one in line ahead of me. Around 3:00pm one of the mechanics comes out to the car in front of me and talks to them and they leave. Doesn't say anything to me. I go inside the shop and he says they're not doing anymore cars today, even though the website says open until 5:00pm. Mechanic says come back tomorrow. Would not recommend. read more

I really like the appointment process and the guys working there were nice! Price is good! See you in a couple of years. read more

Smog Star Express - Clean air check up. - Smog Check Stations Near Me - Concord, California

Rude and weird service. The person working had us wait over 20 minutes outside to check us in. When we got there and he said we need to go outside to wait. Okay. He was working with another customer in the office, which is fine, but why not just check us in and tell us to wait in our car instead of having us wait over 20 minutes standing outside in the cold? When it was our turn to be checked in, he rudely explained that he could not even provide a remote estimate of how long it would take. It was an awkward experience, I don't understand why he couldn't have just paused to check us in and tell us we could wait in our car. We left. read more

Spoke to Robert on the phone and man does this dude know his stuff . Upon arrival I was greeted by Robert who was in the middle of working on a truck, he stopped what he was doing to come and check on my needs(First sign of great customer service ). Once I stated that we spoke on the phone he kicked everything in together . He had all the forms ready to go and got straight to work. In all of my years of getting a Smog I've never seen someone work so diligently and fast in an environment where they are by themselves. Thank you for the great work man , definitely recommend if you are in need of a Smog.The prices are fair and the customer service is great.Keep up the great work robert it is much appreciated ! read more

I have been here before and had great experience. But something has changed...for the bad. Made an appointment for 9am. Walked into the office to be told to wait outside for my turn- no check in, no greeting- just go outside. No seating anymore inside or outside...so standing in the cold. Luckily it wasn't raining. There were 2 people ahead of me also waiting around. After seeing how slow and inconsiderate the "technician" was, I realized I wouldn't be done for at least another hour. Decided to leave this place and will not be back in the future. read more

Smog Star Express - This is the store when it should be open at 8:20 am - Smog Check Stations Near Me - Concord, California

I brought my Ford Ranger in for its DMV-mandated inspection on 10/01/2022. It failed within the category of Catalyst. No definitive explanation was given for this failure. Due to a botched theft attempt requiring repairs, I had to return to the muffler shop that fixed my damaged catalytic converter. The welds were reinspected with no signs of leakage. Next to my regular repair shop to check the air intake system. No problems were found. Next to another smog station that re-tested the truck and found no problems, it passed. This consumed a full morning running around and resulted in another shop's Smog inspection $50 charge. I'm out $70 because of Smog Star's incorrect assessment. I'd give this shop 0 Stars if I could. Find another place for sure. read more

Amazing service thank you! Christopher was super fast knowledgeable and helpful. I would highly recommend!

Not coming back here. They are loaded with hidden fees, not posted on their website. Came in expecting to pay no more than $45, with a coupon. Left paying $65. Coupon was basically useless because its the same discount you get for making an appointment, something they don't tell you. Customer service was also completely lacking, guy was either on the phone or listening to something on his airpods the entire time. Also nowhere to sit, while you wait, and I waited for nearly an hour. read more

Ladies, if you want to do yourself a favor, don't schedule your smog test here. That is unless you want to be treated rudely, delayed for your appointment by 15+ minutes (even when you arrive on time for a SCHEDULED appointment), and then be ignored. I made a few calls and was on my way to Super Station just down the street in no time. I pulled up to Super Station and they immediately pulled my car into their shop and began the test, even WITHOUT an appointment. They were LESS EXPENSIVE, as well. I was done with the test and my car PASSED IT within 10 minutes. My certificate was also sent to the State of CA by Super Station. Safe time, hassle, and a rude experience by starting off at Super Station. Skip Smog Star Express. They are not a star, in my estimation. read more
