I take all my cars to HyeTech. They are experienced, friendly and very professional. Plus they have the best pricing in the area. I take my cars in and John gives me an estimate. I am never surprised after with new work or an increase cost. I trust HyeTech for great service and pricing.

Rebuilt my blown BMW 325i engine. I was told by friends that it would never be the same as how the original engine felt when i first got the car. This place brought it back to life with even more umphh! Gotta be kidding me...car runs like a beast!

A Godsend. My car broke down in LA while I was on a trip from N. Cal.. One call to Ray, a complete stranger to me, and my anxieties were put to ease. He took my car in right away and fixed it as good as new. Even though he could have charged me anything and I would have paid it, the job was done for less than the original, very reasonable quote. Thank you so much Ray. Muchisimas gracias! Tim G. Brentwood, CA

Let me tell you about JCW Auto Repair. On 8/9/2024 I was traveling from Berkeley CA after visiting my son, daughter in law and toddler grandson back to my home in north coastal San Diego. I had my 5 month old Corgi puppy with me, (she was a champ the entire trip). I noticed during the grapevine approaching the LA National Forrest the engine seemed to be working hard. I saw freeway signs recommending drivers turn off their AC during the steep grades and incline and I did so. Google maps redirected me to go through Pasadena to SD vs LA as LA rush hour traffic was slammed on Friday. Travel slowed considerably and I noticed my temperature gauge starting to rise in the stop and go traffic. I turned off the AC again, it was 107 degrees outside. Across the freeway from me was a Subaru car dealership, but it was now 5:01 and I know the service dept would be closed. I took the very next exit as I could see it was an industrial area and there had to be something there. I pulled over in some shade to let the car temp gauge to cool down. I saw the car repair shops were all closed. I thought about calling AAA, but what could they do other than tow me? I called my brother in law in SD, he had me pop the hood and check the coolant which was almost empty. He directed me to drive a few miles just west of my location to an O'Reilly auto parts store and he would coach me how to add the coolant. I started to drive about a block and found JCW Auto repair with the bay doors still open. It was clear everyone was closing up but stayed to help me. Jed immediately went to work, I popped the hood, he could smell the radiator heat. Jed immediately noticed my radiator cap was broken. I explained I had taken my Subaru to the dealership two days prior to my road trip to have the oil changed, tires rotated and the fluids all checked. Jed said the service department should have caught this broken radiator cap. Two jugs of coolant. Jed tried to find a used radiator cap that would work, he finally took one off his own personal vehicle that fit my Subaru. Jed cautioned me to drive the rest of the way to SD at normal speeds with no AC. It was blazing hot out there. He even gave me a jug of water if the temp gauge started to rise again and explained do not open the cap until it cools down. Jed seemed genuinely concerned and worried but felt I should be able to make it to San Diego if I take it easy. I asked Jed how much I owed him and Jed told me to give him whatever I thought was right. I am a widow traveling alone, I am beyond grateful for Jed dropping what he was doing to take care of me and get me on my way. He had along day at work and was ready to go home. Jed really saved me and my little puppy. He saved me an expensive repair bill or even my car breaking down on the freeway. I shudder at the danger of that. My sons and my family are exceptionally grateful too. It should be noted when I got to San Clemente I turned the AC on and the temperature gauge never moved from the middle center line. It was so chilly in the cabin my fingers and feet were numb with cold air. I would definitely, most assuredly take my vehicles to JCW Auto repair for all my service needs and might even drive to Azusa from SD for such quality excellence in service. This is the America I grew up in, where there was honesty, integrity and high moral character among our car mechanic professionals, where a handshake was considered to have as much value associated with it as a man giving his word of honor. JCW is exceptional car service care. Jed and his crew are consummate professionals. Again my profound heartfelt thanks

Courteous of customer's time, polite and professional. Excellence! in customer service. Adrian Yanez

They are not BBB accredited! They do not abide by their warranties/ contracts! They are sketchy! I was recommended to P&G from sals auto mechanic in fontana, I have a toyota celica Gt 01 that had sucked up water into the intake. I needed a new engine. Sal had told me that this was the place to go. Alex, the owner had quoted me a fair price to install a new 1zz motor (the same kind my car comes with originally) he also said he could switch the position of my intake so that it wouldn't suck up water again.(He didn't) The job was to take 7 days and cost me $2200 with a 1 year or 12,000 mile warranty on all parts and labor. However, upon initial payment of $1100 and 12 days later. I called Alex and he said I needed a new air control valve because the car wouldn't idle right, he also said he needed to install a new "knock sensor", something I've never heard of before. It would cost me an additional $250 and another day of work, I said okay. I just wanted my car fixed. Finally after about 12 days and after I paid the $1450 I got my car back, I understand that cars with new engines have a "break in" period of 3 or 4 months for it be in top condition; so I made sure to drive with caution and made sure not to accelerate over 3000 rpms in between gears. After 1 month, my check engine light came on and my temp was spiking. I took it back to Alex and he said I needed a new temp coolant sensor. I paid $125 for the part and he installed the part. The problem did not go away. Not even a day later the light came back on and he said it was suppose to be a different sensor. He told me he charge me for this new mystery sensor, but after he installed it the problem seemed to be gone. I drove my car for 2 months before I got an oil leak. I took it back and Alex told me it would cost $600 for a new head gasket and seals, he also said that he would not cover it under the warranty because it was because of overheating due to the temperature coolant sensor, the same one that he installed 2 months before! Be warned! This company is not BBB accredited! They are sketchy! And they do not abide by their warranties/ contracts!

General repairs.

I've gone to Precision Import Auto Repair for about seven years now, so it's not my first time dealing with this company. I can say they're very dependable. The whole team, particularly Mano and Mike, are excellent people to take care of any situation. They are very trustworthy and repair things until it is finished to perfection. They allow customers to speak out their minds so they can include it into their final evaluation. Their prices are very reasonable.

Amazing work. The owner Kenni is an amazing woman. It makes me feel so comfortable taking my car somewhere to get an oil change especially being a woman because I know they will always be honest with me. I will always come here for any of my car needs.

I bought my Pontiac brand new in 1988. 277,000 miles later it's starting to have a few problems, especially with the fuel injection and passing smog. IS&R fixed its current issues in one day and charged far less than I had expected to pay. Good work done quickly for a fair price. Now I'm trying to decide which of its other problems to have them look at next. Craigs great to work with as well!!!

ou. The owner Lary is a great guy and will work things out for every customer to totally understand what's happening to their vehicle . I trust this place and it's service and would definitely recommend this shop to my family and friends. =) -Kat Critchfield

I was on vacation with my family and I had a tire that kept losing air. This place hooked me up with a new tire valve and got me back on the road in no time! I came in with 20 minutes until closing time and they still provided fantastic service! Great customer service. Highly recommend this place for any tire needs! -Kristie Phillips
