Came here on a weds mid morning in my little Prius for a smog. There was a guy on his phone, sitting on the bench that's facing the entrance of the drive in. He walks up and tells me to go to lane 1. As I'm stopping and he's walking up to me, he's like looks like you have an anti theft steel plate on converter??? We can't smog you. I was like ok. Drove off. Called my husband and he said that's not a thing. I didn't want to argue with him and didn't know if that was really going to prevent him from working. Went to the next smog on my yelp and they did it. Think the guy just didn't want to work. Hehehe Def won't come back. read more

Friendly staff! Professional interaction! in and out in ten minutes. Thank you Grand Smog!

I have been at this place twice with my truck for a smog check. Both times it passed. Service was great !!! The guys here are very helpful and price is very reasonable. I even had a good cup of coffee while they were working on my car. They offer coffee, tea, water and snacks while you wait for free! I love coming to this place. If you need a smog check, this is the best place in Santa Ana. read more

Well, we had another easy experience yesterday and I can't get over how quick the smog check takes. I've been a customer for years and their prices are competitive and the whole process only takes about 10 minutes. Just when I start to get situated in one of the couple chairs that they have out front (I like to get some sun while I wait) they are done!! I go during the week and "non peak" hours so I'm usually the only one there. They have 2 bays so even when I've been there &there have been multiple cars it's still been a painless process. Professional, honest business. read more

Grand Smog - Quick service - Smog Check Stations Near Me - Santa Ana, California

Very efficient and had a nice environment. Like how they provided candy and water. The service was quick and easy. Will definitely come back and recommend to family and friends read more

Everyone working there is super friendly! Most seemed like Vietnamese possibly. A lovely lady met me as I drove up and her calm friendly demeanor put me at ease! I told her I needed a smog check and showed her the coupon on my phone. She confirmed my discounted price. The smog check was done in less than 5 minutes. Fast but courteous. They wished me well on my way out. I will keep coming back to this place! read more

Been several times and they have taken care of me Easy to do business with Will continue to come back read more

Poor service. Incorrectly failed my vehicle for tampered exhaust component. Also incorrectly noted on the report to DMV that the vehicle had two small cats where none existed. Took to Jamboree Smog in Tustin and they confirmed (the guy put his body under the car to check) that Grand Smog was wrong. I also returned here and let the technician (who did the test) know that what he reported to the DMV is wrong and he said what's done is done. Do not go here. read more

I am very disappointed in their customer service. I had a coupon and thought o could use it as I cashed out and they refused! I was charged $25 more and said his manager would get angry with him. I asked to speak with manager and conveniently wasn't there. Not only do they over charge they do not honor their coupons! read more

This location in Tustin on Grand has new Vietnamese technicians now and a is a joke. I have been going to this location for over 10 years and never had any issues until now. The technicians argued back and forth with me about the supercharger on the Mustang Cobra I just bought. It came from the factory with it. I didn't install it and the 'know it all' young technician said it was custom. Google search can't replace years of technician experience but even with that I googled it when I got home after going back and forth with them. I found the CARB sticker under the hood and it clearly shows in the diagram the supercharger. They really have no idea what they are doing! Don't trust you car with these guys. Trust me, take your car to EZ Auto Test Only in Santa Ana for much better service and half the price. read more

Good name change! It used to be Jamboree Smog, new owner changed it to Grand Smog because it's grand service and on Grand :)

This place is a joke! My dad took his car to get checked, and not only were they rude but they laughed in his face for the car not passing the smog check. He was told to contact his mechanic who worked on it and when he did, they responded that they did not need to speak to others. I would hate for anyone else to experience this type of behavior because there's no way someone should be laughed at and be called "professionals." I will never be returning and I hope they read this and realize they are a so rude. read more

Used to be fast and hassle free. This year 2 different techs refused to accept CARB EO numbers I provided on parts I passed with here in the past. Reason I had to provide the numbers on paper is because the parts were 15 yrs old and the numbers are no longer readable. Tech tells me I need a CARB EO sticker on my scorching hot headers. ‍ I tell him even the state referee accepted the CARB EO number on paper. I also tell him I have passed smog here with these parts in the past. Dude just refused to accept all my paperwork and refused to run the smog check. I have been coming here for few years now and have even referred friends here. I won't be returning again. Techs had very poor attitude and zero customer service skills. Refused to listen to my explanations and told me to go somewhere else. So I returned to my prior spot and passed just fine. If you have old aftermarket parts on your vehicle, I would advise not coming here. They used to be very cool. Not today. I'd have to also agree with other reviews from Johnny B and Cristal A. Sounds like a recurring theme with these new guys now. read more

RUN!!! If I could give this review a 0/5 stars I would. Upon arrival the technician, Khanh Phan, had a horrible attitude. Right off the bat, he was speaking very fast and unfortunately there was a language barrier due to his accent. After the smog was completed, he tried explaining to me what I needed to do to submit paperwork to the DMV. I was having a very hard time understanding what he was explaining, which the speed he was explaining things was not helpful either. I told him I did not understand, to which he then started to raise his voice at me asking "DO YOU UNDERSTAND ME? DO YOU UNDERSTAND ME?". Again, due to the language barrier and how fast he was talking to me I only understood part of what he was saying. I responded to him and told him I didn't like the way he was speaking to, as it was incredibly rude, demeaning, and almost an intimidating tone of voice and behavior. He responded with even more anger and hostility, raising his voice even higher at me. At this point the young girl at the front desk intervened. I told him I was done here and left. I highly recommend finding an alternative smog shop, where you would be treated kindly and respectfully. In addition to reading this review, I would also advise you to read the other poor reviews on this page. read more

Quick and easy. Was in and win under 20 minutes. There is a small waiting area with free snacks provided
