Car Care Notes for Union City Drivers

What we keep in mind when we work in Union City.

In the middle of our core area

Union City sits between Fremont and Hayward along I-880 and Alvarado-Niles Road, so it is part of the area we cover most often. Send the exact address so we can confirm the timing.

Short trips to BART

If your car mostly makes short trips, like a quick drive to the Union City BART station, the engine may not run long enough to fully recharge the battery. If it starts slowly, a battery and charging test shows whether the battery or the alternator is the problem.

Alternator repair

Older neighborhoods, tight driveways

Some homes in Decoto and Alvarado have narrow driveways or street-only parking. A level, legal spot with room to open the doors and hood is usually enough for most repairs.

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!
