Hans S.

Very low mile Lexus GS300 had P0440 0441 0446 Evap faults which held up smog inspection. Researching the net I suspected the plastic Overflow Valve on top of the gas tank had cracked and leaked. No way could I remove all structural and moving parts then drop the gas tank to replace it. Had a lot of problems, wasting months and hundreds dollars with Jose at Radiator Depot on Westminster and a mobile mechanic to install a new canister and purge valve per Jose's recommendation, since he had no time to do it. All that work did not solve the problem. It was very time consuming, expensive and frustrating. Cops were hassling me for the expired tag. Finally on recommendation from a guy in Club Lexus, brought it in to Mr Son at Dynamic Auto Repair in Fountain Valley, CA. He charged $100 for diagnostics applicable to repairs in his shop. He used to be a tech for Lexus dealer and has a sophisticated diagnostic computer system to operate and test various Evap components. After 20 minutes, he found a very small leak on top of the Overflow Valve, which would be very difficult to detect with smoke machines. The Evap canister was very likely good. I had bought OEM overflow valve and gasket. Left the car to him. Next day he called and said, valve replaced, problems fixed. He also replaced gratis plastic vent hoses broken by the mobile mech and the substandard hoses at the purge valve on top of the engine, which were incorrectly installed by Radiator Depot. He charged about 30% less than a Lexus dealer quote. I suspected Lexus would likely jack up the costs even higher after I bring the car to them. During the drive home, all OBDII monitors were cleared. Car passed smog the next day. Son is a competent, nice, honest, helpful guy, worth 5 star. All other shops in OC have gotten 1 and 2 stars. One even seriously sabotaged my car and was reported to police and DMV. Highly recommend Dynamic. Will come back to him with my Lexus and all my cars to save money, time, headache with other shops.

See all

J&C Tires & Service

tl; dr great all around. I'll be back…read more Requested quote for mount and balance for 4 wheels using some extra tires I had lying around and Cleo responded quickly. Price was good. I was unfortunately late by 30 minutes, so I waited for two people (I think they both had alignments too?). However I was out by 90 minutes from start to finish. I think they spent about 30 minutes or less on my car which is pretty fast from my experience. They didn't scratch the rims (19 inch staggered wheels like rear 255/35R19) They used torque wrenches. Tires are well balanced using hunter road force balancer and I didn't notice any wobbling or roaring. I'll be back and on time for my other cars :)

Came here on a Sunday bc I noticed my tire had a slow leak and upon inspection found a nail. Found…read moreJ&C via Yelp since they were one of the few tire shops open on Sundays and noticed some cars with aftermarket wheels so thought I would be safe too . Usually don't like going to random shops but no choice this time. They patch the tire but when they were throwing it back on there was an audible loud hiss of leaking air from the bead. The tech tried telling me that it was because of the barcode sticker near the bead that was causing it but if that was the case how did it not leak before when I got the tires originally put on at another shop? Also how did that automatically prompt them to recheck their work? I came for a nail patch job not because there was a leak from the bead? Not only that they trying to tell me that the bead will settle that it will be okay with the loud hiss (extremely dangerous to drive on)... They replace my metal valve cover cap with a plastic cracked one. I point it out and the tech brings my cap back to me. (could be honest mistake but still) I believe the owner comes to put soapy water where the hiss is coming from and obviously it's bubbling like crazy so they take it back to re-do the job. They come back with my wheel, and no more leaking. Overall they did what I paid them to do but the fact that I had to call them out on their work is concerning. What if I was not knowledgeable about cars just took their word for it, I would be endangering mine and other's safety on the road + I would've been out of a metal valve cover cap.

I don't know much about cars, so I was really grateful my dad recommended Tony's OC Auto Service…read moreand told me they were trustworthy. He was absolutely right. My check engine light came on, so I brought my car in and found out it was my catalytic converter. Before jumping straight to the most expensive option, they first tried cleaning it out to see if that would fix the issue. Unfortunately it didn't, so about a week later I came back to have it replaced. I was really stressed because I couldn't afford the repair out of pocket, but they were incredibly helpful and told me about Technet, a credit card specifically for auto repairs. I applied and was instantly approved. They even fixed my car and waited for my card to arrive in the mail before I paid them in full. What really stood out to me was how kind and patient everyone was. They explained everything clearly, what the problem was, what caused it, and how they were going to fix it. They even paid for my Uber rides to the shop and from work while my car was in the shop, with no extra charge. It's hard to find honest and caring auto shops, especially when you don't know much about cars, but they made the whole experience so much less stressful. Whenever I need service again, I'll definitely be coming back.

Their attention to detail and recommendations have saved me so many times from potential car issues. The quality of their work is superb. I worry so much about ever having any car issues, but with a shop like Tony's, I always have peace of mind. They are honest and do their work with integrity and quality. Anytime someone asks me if I know of a good shop, I always recommend them. Thank you, Tony's OC!!!
