The best repair shop for German automotive repair on the planet. After reading local yelp reviews to identify a shop in the area and reading the long list of favorable reviews as I just relocated from the LA area; I took (towed) my 2008 528i w/156,000 miles in to Ivan to troubleshoot multiple issues including battery, electrical, alternator, transmission and battery reset. Ivan took 2 days to diagnose the aforementioned issues and completed the repairs at an amazingly low price. In addition, ethical and as important a really good human being. Thanks for your work Ivan; so greatly appreciated. Kind Regards, Ron

Honest guy and that's rare to find when you're taking your BMW to get fixed. Known Ivan for about seven years and he always comes through.

My car needed both low beams replaced, an oil change and a tune up. Matt was quick to provide me…read morewith a quote that was reasonable. Scheduling the appointment was easy. Brought my car in, went over some paperwork and was told I'd be contacted once the inspection was complete. Sure enough Matt called me to let me know there were some items found during inspection and which ones needed to be addressed right away. After agreeing to the updated quote they got to work. I came back to the shop prior to being told my car was ready, and I think there may have been a delay in getting parts needed (dropped the car off at 9am, wasn't done until 4pm). Other than that, the quoted price is what I paid, there wasn't any pushing to buy a service that wasn't needed. I will definitely be bringing my car back for the additional work needed.

I requested a quote through Yelp and my request was sent to multiple auto shops. I chose this…read morecompany based on location and called ahead to confirm they could do more than just read basic codes. I had already done my own diagnostics and knew the car was running rich. I had ruled out the upstream O2 sensor, catalytic converter (both new), MAP sensor, and fuel injectors. I explained all of this to Matt before bringing the car in. He assured me they could perform deeper diagnostics with their equipment. After dropping off the car, Matt called and told me they had "confirmed" exactly what I had already told them, and that the next step would be pulling spark plugs--for an additional fee. At that point, I decided to go elsewhere. What I don't understand is why I was still charged the full $85 diagnostic fee, plus a $4 hazardous materials fee and $3 shop supply fee. Plugging a car into a diagnostic scanner does not generate any hazardous waste--no fluids are drained, no chemicals are used, and no parts are replaced. There's nothing about a basic scan that would justify a hazardous materials charge. That kind of fee typically applies when disposing of things like oil, coolant, or other regulated waste, none of which occurred here. In the end, I paid $92, wasted time and gas, and learned nothing new. The most concerning part was Matt admitting he didn't even know spark plugs would need to be checked as part of further diagnosis.

I hired this mechanic to replace the cinching actuator on my Tesla. Immediately after he completed…read morethe work, my car began making loud, abnormal noises that never existed before. My door handles started making a loud squeaking/horn-like sound. When I opened my trunk, it sounded like it was malfunctioning or "dying." The same noise occurred when the trunk closed. When I opened my doors, the noise came from the trunk again. Even when I backed into my driveway and pressed the brakes, my car made a loud honking sound. All of these issues began after his repair. I contacted him immediately to let him know something was clearly wrong. Instead of taking responsibility or offering to inspect the problem, he became defensive and accused me of lying. He claimed the issues were preexisting and said I had tampered with my own car. He talked over me, became argumentative, threatened to cut business ties, said he would block my number, and abruptly hung up on me. He also blamed me for "self-diagnosing," even though I was simply describing the symptoms I was experiencing--something any customer would do. I hired him because he is the mechanic. It is literally his job to assess, diagnose, and fix problems. Instead, he refused accountability and demanded I pay him an additional $250 just to run a diagnostic to determine whether he caused the problems. Every reputable mechanic I've worked with in the past has stood behind their work. This one did not. He then sent me a disclosure form he wanted me to sign stating that I would only receive a partial refund if he decided the issues were his fault. I did not agree to this. When I didn't respond to his repeated messages, he texted again saying that after "some thought," he would now be willing to refund only a "portion" of what I paid. I paid him $350. When I declined to pay the additional $250 diagnostic fee, he argued with me and repeatedly stated that because I said no, I was "accepting that this is the end of the issue," then hung up on me. To document the abnormal noises, I opened and closed the liftgate several times. During this process, a panel that concealed the wiring fell off its hinges. A Tesla-certified mechanic later told me this was because the panel had not been screwed in correctly. I ultimately had to hire a Tesla-certified mechanic to fix what was done. Based on the symptoms I described over the phone, he immediately recognized that the wiring had been done incorrectly. When he inspected the vehicle, he confirmed that multiple connectors were improperly rewired, including the liftgate being wired into the speaker system and the trunk light being wired incorrectly. The horn was sounding as a warning that something was wrong. This was not only careless -- it was a safety concern. This mechanic was rude, dismissive, unprofessional, and completely unwilling to stand behind his work. Based on my experience, I would strongly caution Tesla owners and anyone with a modern vehicle against using his services. *** This is in response to Jane's response. PLEASE READ as this is very important. James claims he offered a "warranty check," AKA "diagnostic," but only if I paid him an additional $250 for his time. I declined. At that point, he repeatedly talked over me, read a disclaimer aloud without allowing me to respond, and ignored my polite requests to speak. He then told me he was "ending this relationship," said he would block my number, and abruptly hung up on me. He did not offer a full refund--only an unspecified portion of what I paid. I uploaded a photo of the revised invoice he sent after damaging my vehicle. In that invoice, he attempted to insert a disclaimer stating that I would accept a partial refund only after he decided whether he caused the damage. The document does not specify any refund amount. Had I signed it, I would have forfeited my right to a full refund. After my Yelp review, I sent James videos from a Tesla-certified mechanic explaining exactly what he did wrong. He incorrectly reattached the wiring, connecting the liftgate to the speaker system, which caused the loud horn noise. On a Tesla, this sound is a safety alert indicating faulty electrical connections. James presents himself as an honest professional. My experience was the opposite. I was spoken over, yelled at, threatened with being blocked, and treated with hostility when I simply asked questions about the damage done to my vehicle. I have never been treated this way by any business before. Based on both his conduct and the documented mechanical errors, James is not qualified to work on electric or modern vehicles. His behavior was unprofessional, aggressive, and manipulative. I strongly recommend that anyone with a newer or electric car take their business elsewhere. Quantum Mobile Mechanic is not on Better Business Bureau. I reported him to the BAR (California Bureau of Automotive Repair).***
