I had such a great experience with Auto Diagnostic & Repair in Antioch! From the very first phone…read morecall, their customer service was amazing. They were friendly, professional, answered their phone, and were always easy to get ahold of. When I brought my truck in, they even had a shuttle available to take me home while they looked into the issue. They ended up finding out that the repair was something they couldn't handle due to certain Toyota-specific conditions with the part. Instead of trying to take my money anyway, they were completely honest and recommended that I take my truck directly to Toyota to have the service done. They didn't charge me anything, and I actually gave them a tip because I truly appreciated their honesty and integrity. You don't always come across businesses that are willing to turn away money and point you in the right direction. Everyone I dealt with was incredibly nice, helpful, and professional. I 100% recommend Auto Diagnostic and Repair for any truck or vehicle needs, and I will definitely be bringing my truck back to them for future services!

I attempted to replace my own headlight 3 times it wasn't coming on, So I assumed it was electrical. I drive a 2013 Hyundai sonata. Charged me $160 diagnostic and $232 to replace light bulbs. $392 for LIGHT BULBS!!!!! Never checked my fuses, because I didnt request it when I got there. (The gas lighting is crazy) For my horn, didn't even check the relay or fuses (my car was stolen 3 years ago so the piece to cover my steering wheel column isn't covering my ignition). They must've thought my car was stolen recently so they didnt bother to check my fuses or horn relay and overcharge me for something else. Complete rip off. Of course I had them take out the very expensive lights and took it to a different shop where I can talk directly to a mechanic. Waste of money! Taking advantage of woman drivers. Running a business unethical. You should be ashamed of yourselves.
