Martin and the team have been very helpful, patient, professional, and honest and I would like to share my experience to let people know they are truly a hidden gem. Here is what happened - It started with the engine light came on and I went to the first auto repair shop before Fremont Auto Center. The first auto repair shop did a diagnosis and said ALL 3 components need to be replaced and that's $5K. I decided to ask around and my friend recommended Fremont Auto Center so I called them. Martin spent 25 minutes on the phone with me patiently listening to my description and asking follow-up questions. I decided to have them to do diagnosis. The day I arrived, Martin had a error code reader with him and did the diagnosis and then right away he showed me the error codes and after his discussion with the team, they noticed all error messages are mentioning voltage. After all, they were able to only need to replace the battery and have the car fixed and that's a VERY BIG cost saving for me comparing to the other auto repair shop (less than $600 vs. $5K). Also Fremont Auto Center was able to show me a full report with detailed information. I just want to thank Martin and the team for their honesty and willing to dig into the root cause of the issue. I will recommend them to all my friends and definitely go to them for all my car moving forward. Good luck with your car, and definitely have Fremont Auto Center to be on your auto repair shop list. HIGHLY RECOMMENDED!
