They were great - professional and quick. The two people I interacted with were very pleasant and also clear in their explanations. Important for me is that they do both smog inspection checks _and_ smog repair. My car is getting older and someday it will need the smog repair part. I'm really pleased to find a shop in advance that I would trust to handle that. Four Corners 76 was recommended by a mechanic who had said they were both good and honest. I absolutely got that vibe about them. read more

They do a good job working on cars. They are professional, and have good mechanics. They use new parts, and if there is a defect in a part they replace it without any fuss. That has been my experience. read more

Rick, Dan, Justin, Chan and crew have been working on our cars for over 20 years. I can't say enough good things about the service, the attitude and the prices. Currently I drive a newer Mercedes and my wife a newer Lexus. Over the years, we have never hesitated taking any of our cars to them. Everything from a basic car care (oil change/inspection) to brake jobs, electrical work, tires, transmission work and tune ups. They have all the latest computer equipment and diagnostics and won't hesitate call the dealership if if is something very unique. The service and value compared to the dealerships is huge. The only thing I like better about the dealerships is they wash your car. But that sure turns out to be an expensive care wash! :) I highly recommend giving these guys a chance. You will be pleasantly pleased and your wallet will appreciate it to! read more

This place has excellent qualities. Great mechanics, great customer service, great prices, and great quality gasoline. I love this place so much I even came to work for them. read more

6 years ago I have them 5 stars, been keeping on going there including today and no change. Same professional service by the two guys in the garage and the friendly cashier up front. Highly recommended. read more

Here's my experience at this station and why I won't be going back, ever. In 2010 I took my Tacoma in for a smog certificate with the "Check Engine" light on. I even had the failure code. They ran the smog test, with the light on, which of course failed. $49.76. I had them do the necessary repair and rerun the smog check. $472.86. The truck passed and I got it registered. The next day the "Check Engine" light was on again. When I go back to the station a day later, ironically the light is off. It's pretty obvious they replaced the wrong part, but the mechanic tells me to wait until the light is on, then bring it in. He didn't even offer to check it out, or rather, he would if I wanted to leave it for a day or two. At this point my truck has been at their station for several days and I'm getting to work with one of my employees. Unable waste any more time with these guys I took it to a reliable mechanic, which I should have done in the first place. They repaired it properly by replacing the correct part. $364.39. Grand Total: $887.00, plus lost time, plus the actual cost for registration. I learned a couple of important lessons: Always, always, ALWAYS pay with a credit card so I have recourse in such a case - I used my Debit card, duh! And, go to a reliable mechanic in the first place - Mike's Automotive Service in Pleasant Hill being one of them. read more

My family has been coming here for upwards of 20 years now, and the service is and has always been consistently amazing and reliable. They never overcharge for parts or labor, and they call before making any alterations to get the go ahead based on pricing. They will always tell you if the fix is necessary and viable, or if it's safe to put it off for a few visits. Staff is kind, courteous, and knowledgeable. 10/10 would always recommend read more

I rarely stop at this 76 gas station and when I do, it's usually only to fill up the tires. Before a long road trip this morning, we stopped in and I went inside to get us drinks for the road. The cashier has got to be the friendliest person I have ever met who works at a gas station. Her name is Eva, and she had the biggest smile, a friendly personality and honestly just made me feel extremely welcome. At a gas station. You rarely get that kind of service in most restaurants and retail stores. She even offered me free coffee. I would come back here to fill up the car just so I can get that kind of customer service again. Thank you Eva. read more

We initially met Rick, the owner, who helped us purchase a car for our daughter on his lot. He made sure the car was in great shape and helped negotiate a fair price. But now that we've taken my other car to him for service, I'm a fan for life. His mechanics are all awesome and respectful. His clerks behind the counter are warm and welcoming. I can text Rick about a car question and he responds within a couple hours, if not minutes. He treats his customers like family. We'll be taking our cars here from now on. read more

AWESOME EXPERIENCE!!! on monday, 3/19/12 my '08 dodge avenger overheated. i was in concord for a dr appt and had to get home to vacaville. i tried putting a 'band-aid' on the problem, cross my fingers and head home...haha NOT.turns out, the part was made of plastic and it had cracked completely off. the tape i tried to fix it with was a silver, heat-sensative tape used to seal leaks in air hoses. lol. it was all i could find at OSH. my car began overheating immediately after i refilled the radiator and attempted to tape the crack in the hose... it was near the end of the day, and i pulled in to the four corners union 76, hoping they would be able to help me. not only did they help, but they fixed my car immediately! i arrived at 3:30, i was helped by a man (i wish i remembered his name...he was awesome!!!), he called around for the parts but said they may not get them until wednesday (in two days). so he got in his own personal vehicle and went to get the parts i needed. my car was done before closing and i was back on the road on my way home in time to fix dinner :) i would highly recommend taking your car here for service! the staff was friendly, professional and while it was being fixed, they even vacuumed it and dusted the dash. it was quick, affordable, and overall a pretty nice experience, given the circumstances. nobody likes having car trouble, but they took the pain out of it for me that day for sure and i just wanted to say THANK YOU!!!!!!! (my service order says: serviced by 2557, written by 8937) kudos to your staff for excellent service!! sincerely, catherine m. read more

I am disabled, and sometimes pumping my own gas is not an option for me. This might be the last remaining full service gas station in Contra Costa County, and Sebastian is the best attendant ever. Many, many thanks! read more

I brought in my car for a smog check/repair. Dropped it off early on a monday - 3 days went by (with me walking to work and arranging for someone to pick me up from work) and then they tell me they need to order a part. This was a simple part, one that I could have swapped out myself, but I figured it would be easier to have them do it. I ask how long it will take for the part to show up. They say 4-5 days. When it comes in they want me to bring the car back and drop it off. Well, its been 2.5 weeks now. My registration is now expired. I still dont have valid smog cert. Its taken them 3 weeks now for a very, very simple procedure. I dont think these guys understand how inconvenient auto repair work is. I mean, if I was jobless that would be one thing. Pretty ridiculous. My next step will be contacting the California BAR to file a complaint. read more

I have taken my Chrysler Minivan here four times and have had only the best service and experiences! I make my living with my van and it has a lot of miles on it so I need someone I can trust to keep me on the road and I trust these guys. One of my visits was for a smog certificate, twice for mechanical problems and once for a frustrating air conditioner problem that befuddled my previous mechanic. Within a couple of hours the guys at Four Corners had diagnosed my ac problem and fixed it for a very reasonable price. Four Corners is a Union 76 gas station with the vehicle repair in the back of the place and that's not unique but it is unique for several reasons: When you walk into the service area a real live mechanic greats you and asks how they can help as opposed to most places where a desk jockey writes you up and promises to call you later. The guys that are going to work on your vehicle want to hear from you what your issue is and that is important to me. It isn't apparent that there is a supervisor in the shop but that is because the owner, Dan, is one of the guys in blue uniform with his hands dirty working on a vehicle. If you are observant you will see his mechanics walk over and tell him why you are there so he knows what is going on in his shop. Dan is truly a 'hands on' owner and has been there for many, many years and has a reputation for being a great mechanic that treats his customers fairly. These mechanics know what they are doing and if you want to fix your vehicle at a fair price then Four Corners Union 76 is your kind of place. It is no surprise that they are always busy but don't let that deter you. Find a place to park and walk in ... Four Corners 76 Station won't disappoint you. This is THE place to go for your auto repair needs. read more

I've been coming here ever since I received my license. Make sure you schedule and appointment if you're planning on getting a smog, they fill up quick even on weekdays. Most of the time the guys in the garage are pretty busy and don't have time to BS, but the lady inside is always energetic and cheerful. read more

Needed to fix one of my tires, I called 5 other places and they were charging $28-$37 and the fastest would be a 45 min wait. Called this guys and they did it for $16 in less than 5 mins, in and out! The guy who fixed my tire was Kirk, super nice and quick, didn't try to sell me any extra crap, just straight to the problem, solved it and I was out. Hard to find that so they deserve 5 stars! read more

Always friendly and caring. A great place where we continue to have all our smogs checks performed.

1-17-09: Four Corners is a 'Gold Shield' service provider--highest rating from CA.* I shopped by phone to smog test only places to test a pre '96 Toyota van. What a difference in prices!** (CA requires additional testing on older vehicles, and sometimes testing vans will cost more.) These people were well-spoken and gave me a same-day app't. Clean and professional and on schedule, the staff was courteous, well above average, and swift. The staff was willing to respond helpfully to questions. Judy, a 17-year employee at the cash register, is a kick. * btw: CA has a program to help those who can't afford their smog repairs. Who knew? I didn't need it and probably don't qualify, but you should know: This station has a brochure or search DMV website. **In a time when businesses may be tempted to charge high with the customers they do get, it's not happening here, thankfully. read more

Great service and quick smog check before I leave they said it was done passed wow drove in and drove our same day one hour fast thank you

I got my leaking tire plugged up last month. Unfortunately the slow leak continued, so I went back in to Union 76. The technicians there were friendly and offered to re-plug the leak (at no charge). As I was pulling out, they noticed another leak, so he plugged that leak for me and only charged me minimally for the second plug. As he was looking at the tire, he began seeing more and more leaks coming from the tread of the tire. It turns out that my tire needed replacing and he recommended that I go to Costco and tell them that he sent me. The technician did not pressure me into purchasing a tire there...that was really good! I did end up going to Costco Tire Center to get 2 new tires...that was a bummer on the budget! read more

My favorite mechanics and for a lot of my relatives that take their vehicles here. They get the job done!

Always has good service! Also friendly staff. Highly recommend to get your smog check done here. Great prices quick service.

I went this saturday for a smog check and the customer service was great! I waited about 15 minutes and it passed. I will definetly be taking my car back when it needs the smog check. Keep up the great work. read more

Far & away the best mechanic/auto repair place (thanks, Dan!!) over the years for all my cars, no matter the car, the age, the problem. Just yesterday, I needed a brake & lamp inspection & I was in & out quickly, cheaply, and PASSED with an early '90s accident victim, now zombie, back from the dead & street legal! read more

I've used Four Corners Service before smoging my van and they did excellent work.So this time I broght in my newly purchased van for heater work and once again excellent job! Now im ready for a trip to tahoe. Thanks Mike & Four Corners Union 76 Service! read more

Come here once a month. Gas lasts long time!

Got our car star smog tested here. I called around and it was the best price around (February, 2013), the service was good, and there's a nice warm clean waiting room for customers. read more

Got my air cooled beetle smogged here. Seems to be the only place that will smog an older bug!

If I haven't already reviewed them, I'm doing it now. These mechanics know how to smog. They know how to work with older vehicles too. They helped with my 1994 Buick Roadmaster Station wagon and I have returned to them with all my other vehicles since, 1995 Toyota Corolla. And will bring my newer acquired vehicles, 2001 Nissan Frontier Truck and 2000 Subaru Outback. read more

Got a smog check here. Mike took care of my car and was friendly and efficient. The waiting room was clean and air conditioned, which was welcome on a hot summer day. Took less than 15 minutes to pass the check and check that annoying box for the DMV. read more

I brought my car in at 8 am and by 3 pm they still haven't even looked at it. They have found the time to look at and work on nicer more expensive cars that were brought in after my car, but my car still sits waiting to even be looked at. read more

Four-Corners 76 makes my day again. Always great service and reasonable prices but they even remedy my mistakes for free. While Steve noted a problem that would keep me from passing a smog test (saving me from the expense of a useless test), and noting that this was something the dealer would fix for free, Kirk explained (and demonstrated) what was wrong with my brake sensor system. I've been going here for years and never hesitate to send friends and neighbors their way. read more

I can't begin to say how pleased I am with the tune up/repair service form this station. All the people working there are pleasant, professional, and really caring, They have serviced my cars for 15 years here and never a problem. I even bought a car from them and it has been perfect. They are a station that takes customer care seriously. They go beyond what one would expect of any business. Bravo to Rick, Dan, Justin and all the guys. read more

Who likes to go get their car smogged? Not me, but I had to, and on my lunch break, no less. The guys there were AWESOME, fast and super friendly. When I went to pay, the girl inside was nice and helpful. Great customer service all around. I couldn't be happier with this shop. read more

My car overheated the other day while I was driving past the station. I pulled in and assumed I would have to deal with the issue on my own. Instead, one of the mechanics came out and waited with me while the car cooled down. It was nice to have someone help me evaluate how serious the issue was so I could decide whether it made sense to continue driving to San Ramon for a meeting with my boss. My initial plan was simply to fill up the reservoir with water and continue driving to San Ramon. However, based on the mechanic's input, I decided it was best to call my boss, explain the situation and work out of our Concord office instead. There's a good chance his advice prevented me from breaking down on the highway. Thank you! read more

Took my old car in for a smog check on the appointed time, it was tested and to my surprise, it passed! This station's smog test was $20.00 less than an outfit on Concord Blvd. that I used to go to. The workers were professional. I'll never use another smog test center in the future. I give this place 5 stars! read more

I was rolling around on two spare tires and wanted to check and fill the air pressure in them. every gas station I go to always has a weak air pressure machine and half the gauges don't work. I was at another gas station and a gentlemen recommended this 76 station to me. i headed over there with less than 30 psi on one of my spare tires, lucky i made it. one of the two air pressure machines felt like it was leaking some air but still got an accurate reading, and i know because I tried the other one which worked and it was accurate. I used the good one to fill up the air pressure. not only did the gauge read correctly, it went up to 60 psi with no problem. It filled the air up super quick, where other gas stations couldn't even handle more than like 40 psi. I could feel the pressure in the hose too when I was holding the handle down to fill the air. now I can feel safer that I have 60 psi in both my spares and it took less than 2 minutes to fill them both. every gas station should supply sufficient and working air pressure machines. major props to the owner of this gas station for taking the initiative to provide a needed service that other stations do not. read more

I've been a customer of this establishment for years, they are fair, honest, and the prices for the work are good and what you can expect. They've fixed my 95 Lincoln when the work was enough that I thought I should have junked the car and they were so good that I'm still driving the car today. They now have my Jeep that sat for three years in my driveway not moving and what they've done is amazing! It's perfect. Cant ask for any better treatment, better prices, or better work. read more

I gave it five stars because i had EXCELENT service there :) I brought my car for a smog check and they gave me a same day appointment,the staff was super friendly,Jose was very polite and helpful,i will definitely keep coming back,four corners are the best!good job guys! read more

I have been bringing my car here for years. Every mechanic here is awesome. They are knowledgeable, efficient, and very customer service oriented. They are also very honest! I had to take my Honda CRV to the Honda dealership for recalls twice and both times Honda told me I needed very expensive repair work done (I had not asked them to check anything beside the recall issue). When I brought my car back here and told the mechanics about the repairs "needed" they said I did not need repairs and the parts in question were just fine! I come here for everything, including gas. The cashiers Kiki, Jesse, and Eva are so friendly as well. Everyone here is a big, happy family. I'm a customer for life! Thanks Four Corners! read more

I pulled into this service station on a rainy day with a bum windshield wiper. The mechanic was super helpful and thorough. He fixed my wiper, cleaned it carefully, and offered to check my oil, too. What awesome customer service, especially for a customer who wasn't even filling up. Next time I am in the area, I will make a point of going back. Thank you! read more
