recommended by a couple of them. Well he did not disappoint. We called, he scheduled us in, he came and he fixed it same day. It took most of the day but it was done here at our home without having to tow it anywhere. Of course we will use his services again.

diagnosed the issue and saved me hundreds, if not thousands, of would-be costs had I listened to the first tech. He was fast in responding and very professional.

and drive to get the job done efficiently and effectively. He works with OEM parts and offers warranty on his work equivalent to that of dealerships which is extremely rare for small business auto mechanics. He replaced the starter on my Infiniti Q60S. The starter is located in a place that's extremely difficult to find space to remove it, but with a little improvisation he made it work! He also buffed out a few minor scratches on my front bumper at no cost! His prices are very honest and his labor rate is extremely reasonable, especially in this economy. Definitely recommend Stewart Mobile Repair for all your auto repair needs. I know I'll definitely be calling him in the future!

Frequently Asked Questions

Can you diagnose a car that won't start?
Yes. We test the battery, starter signal, charging system, and fuel/ignition clues instead of guessing at parts.
Do you only scan codes?
No. A scan is just a starting point. We use the codes as a clue and confirm the real cause with practical testing.
Can you diagnose a check engine light?
Yes. We read the codes with professional tools and inspect the likely causes so you know what actually needs repair.
Do I pay for diagnostics if you do the repair?
We charge a mobile diagnostic fee that covers travel and testing. If you have us complete the repair, a portion of that fee is applied to your final bill.
