    Invoice on Smog Test and Repairs for defective Air Intake Hose.
    Lucia R.

    Customer Service: I recently took my 2015 Honda Civic for a smog service. This shop was recommended by a AAA staff. I attempted to make an appointment via the phone, but no one answered which prompted me to go in person. Staff is friendly and helpful. I was able to get my car service on a walk-in which doesn't happen often. My first smog test failed due to an air leak hose being defective. The technicians quoted the part that needed to be replaced and showed me where in my car the defective part was leaking air from. I had my Honda Civic serviced the following week because the part had to be ordered. The part was replaced and second smog test was ran and passed the smog test. The car service took less than an hour and I was in and out of the shop. Quality: Excellent quality service. It has been a week since I drove my car, and I noticed that it runs smoother after part was replaced. Prior to work being done on the Honda Civic the car would halt for a second before taking off. Price: Affordable. Cost of Smog Service Check & Labor Fee : Total $41.75 . I had a $10 discount which was applied on my first service for a total of $31.75. Second Service: Smog Test and Labor on Vehicle total : $117.09. I will definitely come back for a smog service! I forgot to mention their seating area is small but the AC is running cold so you might want to take a sweater if your are going to wait inside.

    Stellar service, friendly, nice facility, nice view. A+ Thank you! Has dyno style for older vehicles!

    See all

    Walked in with no appointment. Walked out 10 minutes later all done. Doesn't get any better as far as smog checks go.

    My hot, sexy minivan needed a smog check to complete registration. Running out of time, I went…read morehere. It's family owned and operated. Excellent- I prefer that. The owner(?) was really nice. My minivan should've cost 69.95 to have it smogged, but he gave me a 10 dollar discount. No idea why, but I'll take it! He estimated 15 minutes and it was done in 15 minutes. Why the 3 stars? The office is filthy. Seriously. I know, it's a car shop but even a quick vacuuming or dusting would've made this place more appealing. I was only there for 15 minutes, but it can be a bit cleaner. With that said, I would return and would tell others about it.

    My wife took one of our cars to Smog Depot #1 today for a routine smog test…read more The car failed the test and the guy that performed the test ("Mohammad") told her that it's a oxygen sensor problem. We own 2 of the exact same cars ("His &Hers") and I am very familiar with them. A problem with one of the four oxygen sensors would have illuminated a Check Engine light on the dash, which is a automatic smog test fail (before they even hook up to the machine). Final review to come. 4/17 Update: The reason that the car did not pass the smog test was because the the cars computer was not ready to be tested. This can be determined immediately when the test connector is plugged into the cars test (OBDII) port. Basically these scammers charged us $60.00 to tell us we can't test your car. They can now expect to be contact by the BAR (California Bureau of Auto Repair) regarding their shady practices.
