OUR REVIEWS
Stephanie Hubbard, 07/01/2025Ken’s Auto Center was amazing!!! I have a 25 year old Jeep and had been dealing with an overheating engine for three years. It was supposedly repaired by a different mechanic three times. While visiting San Diego my car broke down. I took it to Ken’s and they treated me like family. When they went over the engine, they found a lot of issues that showed the prior mechanic clearly didn’t know what they were doing. Ken’s team were very knowledgeable and explained everything to me. We discussed the critical, suggested, and future repair options and they had very fair prices. The team went above and beyond to make sure I could safely make it home, 500 miles away, and said they would help find me a reliable mechanic where I live. I had to go over the Grapevine and every time in the past my car had always come close to pegging the red line or overheating. This time, it was the end of June and over 100°. My engine never got above midpoint on the temperature gauge and I had my AC running the whole time!!! Ken’s Auto Center’s team are true saviors in my book! I highly recommend Ken’s Auto Center to everyone in San Diego. It is clear why they are still in business after 24 years!!!
