Downey, CA Reviewed : 12/07/2025 Comment : **Please read before going here -- especially for a smog check.** I'm officially done with this shop. They may be good at repairs, but at what cost to the customer? I took my '97 car in for a STAR smog test. The car *passed*, but JJs Auto refused to issue the certificate because my catalytic converter didn't have a serial number. I've owned this car since 1997 and have never once had that be an issue. JJs then told me they could "fix" the problem by replacing the converter with one that had a serial number -- and quoted me an outrageous price to do it. When I asked if they could lower the cost, they said no, so I left to look elsewhere. At this point, I felt stuck. Once a shop performs the smog test, other shops won't redo it since they can get flagged. So I had no real choice but to replace the converter. I found a muffler shop that did the job for **half** of what JJs quoted. Still expensive, but at least reasonable. After the replacement, I rushed back to JJs, and this time they issued the certificate -- but not before charging me an additional $8 on top of the original $90+ I had already paid. I asked whether the catalytic-converter serial-number requirement was a new California law. They said no, it's been around for a while -- then added that "most shops are lazy and don't check under the car... you just happened to be the lucky customer we decided to look for it." That's when it became clear: they **could** have passed me the first time. They simply chose not to. It felt like a blatant upsell and a total rip-off. Dishonest shops eventually get exposed. **I will never return to their shop.** 1 Reviews Brenda m. Downey, CA Reviewed : 11/29/2025 Comment : JJ is awesome. He's straightforward and prices are reasonable. I went to get some screws on my front wheels replaced and it didn't take long even though I was a walk-in. He was able to squeeze me in and assist me. If you're just a girl, like me, I'd recommend this shop. 1 Reviews Tanya l. Downey, CA Reviewed : 11/11/2025 Comment : Took my car to be smogged and they told me I did not pass due to an oil leak and oxygen sensor. I took the car to my mechanic and it was bogus fail! Nothing was wrong with the car, took the car to another smog check and it passed. They took my money and wanted me to fix something that had nothing to do with the smog check. Will never return. 1 Reviews Chris venegas Downey, CA Reviewed : 11/01/2025 Comment : I have brought my cars here for all my needs it’s a straight business no funny stuff you pay great prices for great service and they definitely get the job done. 1 Reviews Daniel romero8l Downey, CA Reviewed : 10/22/2025 Comment : I highly recommend this place they do outstanding work and will work with you with prices and have great service and are extremely friendly. 1 Reviews Faig freihat Downey, CA Reviewed : 10/15/2025 Comment : 1 Reviews Daniel do Downey, CA Reviewed : 10/10/2025 Comment : Fast, Reliable, and Trustworthy.

Also, I loved their $20.00 off smog check coupon. 😄 1 Reviews Michael s. Downey, CA Reviewed : 09/24/2025 Comment : We had a really smooth and positive experience here at JJ's. Was sent here after two mechanics including the dealer couldn't diagnose the proper issue. They were able to pinpoint exactly what to fix so my car could pass smog. JJ went above and beyond to ensure we left happy and our car in the right condition. We will be back whenever we need anything. Thank you!! 1 Reviews Ivonne nieto Downey, CA Reviewed : 09/23/2025 Comment : Called about 20 minutes before arriving and asked about availability for a smog check. When I arrived I went to their front office and a serviceman immediately greeted me and another employee took my car. The employee said it would be about 20 min. It was quick and easy to do. I have a 2017 rav 4. Page 1 of 34 |<< 1 2 3 4 5 6 7 8 9 10 → >|
