    They left a big nick-scratch on my bumper right before the tailpipe. Whoever was inserting or removing the emission device that's inserted into the tailpipe was careless. I understand my car has chips but the nick is too big to go unnoticed. I've been to several smog checks prior to them and the nick wasn't there until after bringing it to them. I emailed JJ and was told I'd be given a call back the ff day- but that was a week and a half ago. The bmw i brought to them is considered a classic and anyone would find this an utter carelessness. Its a project car that's driven less than 500 miles per year and usually covered as seen in one of the photos. But hey, since it's not theirs, they can just carelessly scratch it. In addition, i still haven't gotten my registration sticker after passing the smog since they sold me and installed a new catalytic converter. All i really need is just a touch up paint worth $30-$50 and for them address this concern as he stated but looks like it's not important to any of them.

    Car immediately being serviced.

    I've been a loyal customer for a long time and for good reason. JJ's is the most trustworthy and honest mechanic you'll ever find. They are here to help people with honest and reliable work. Their customer service and empathy means the world to me. I will never go anywhere else. I refer everyone I know to them and you should not hesitate to bring your vehicle here as well.

    9:15 a.m Arrived at JJ's for a smog check and it's currently 9:23 a.m. and haven't heard a thing about servicing my car just yet.

    See all

Second was a 2002 Yukon Denali, needed a transfer case rebuild. Just recently my wife's Dodge Durango had been giving us problems. Turns out it wasn't the transmission, but the TCM solenoid. With Angel's honesty, attention to detail, and great work ethic, I've had all repairs done correctly, with minimal downtime, and not being ripped off. He explained all issues so a non-mechanic as myself can understand. Thanks again Angel!

This is basically the 2nd worst thing that could happen to a vehicle IMO The job did take time but I made it work with getting around. Angel and his team did have to do some trouble shooting because this specific transmission requires the valve body to be primed on the bench prior to installation. He rebuilt the entire core and also changed out the engine rear main seal. Now, the transmission feels better than ever. I had to give him a little bit of a hard time about not having Zelle which he ended up getting after. Overall I would say, he really does care about taking care of his customers and will make sure the job is done correctly.

I found Francis through an online search because of the many positive reviews, and during our first interaction he was friendly, professional, and seemed very knowledgeable. He ordered the part directly from Acura and quoted me a fair price. My car was ready the following day, but when I arrived to pick it up, Francis informed me that my vehicle had been involved in an accident while in his care. He explained that another driver had been speeding through the parking lot and crashed into him. He gave me the other driver's information, and I contacted him immediately. The other driver gave a very different version of events. He stated that he was backing out of a parking space and did not see Francis. He also told me that Francis provided his driver's license information but refused to share insurance information. Now, more than a month later, I still have a damaged vehicle and have not received insurance information from Francis despite multiple phone calls, text messages, and outreach from Mercury Insurance. I trusted this shop to take care of my car, not return it to me in worse condition and leave me responsible for a $500 deductible. What has been most disappointing is the lack of accountability and urgency. Francis acted as though this situation was not a major concern and repeatedly assured me that the other driver would "take care of it," which has not happened. According to the other driver, Francis even asked him to change the story about what happened. I chose this business because of its strong reviews and the image Francis presents, but my experience has been extremely stressful and disappointing. I believe customers deserve honesty, transparency, and responsibility when their vehicle is in someone else's care.

When I pointed out the banner at their shop that says "Free Brake Inspection" and their website which states Free Brake Inspection, he retorted that their website also states they do free smog checks, but he states they do not even do smog. (When relooking at their website, they do not mention free smog anyways.) Lorenzo stated the brake inspections were not free and the website got it wrong. When I asked him for the person in charge he stated Erika and Ezekiel were in the parts dept. It is a shame Lorenzo was the only advisor handling a long line at check in. He stated Corporate was aware of the brake inspection charge discrepancy. If they are aware and he is aware, why try to charge a customer for a "Free" brake inspection? After leaving our car here, we heard the next day of a list of repairs needed. Lorenzo stated they believed our brake caliper was seized but could not confirm it. He attempted to charge us an additional $289.47 for the brake caliper service and $152.10 for the brake fluid service in addition to the brakes and rotor replacement service charge we were expecting. The issue is that when we asked Lorenzo if he could confirm if the brake caliper was truly needed to be replaced, he could just say he highly suggests replacing it. From the beginning, this place was trying to scam. I reached out to Alex's Auto Repair in Cypress, who confirmed they could verify if the brake caliper would be needed. Alex's Auto Repair stated there would be no need to waste extra money if he could confirm the issue. Alex's Auto Repair serviced us, and simply lubricated our caliper without us needing to pay over $800 for the whole brake service like Downey Care Care was quoting us. Alex's Auto Repair took the time to verify the issue, charging us less than half of what Downey Care Care center wanted to charge. My issue with this location is they would have happily overcharged us for a service that was not needed. Take your car to Alex's Auto Repair, save your time and money. While Downey Care Care Center was busy playing around, we had to spend extra time and money booking a rental car. (Photo on the left is from Alex's Auto Repair who took the time to verify the concern and lubricate our caliper. The photo on the right includes one page of many pages of services recommended by Downey Care Center including replacing the brake caliper and fluid exchange had we chosen to go that route.) Makes me question if the remaining suggested repairs (not all pictured below) by Downey Care Care Center were even necessary.
