Hummer is a brand that takes power, off road capabilities and reliability seriously. Gilmore's Auto Service highly recommends regular general maintenance to avoid high-cost repairs that can arise in some models and from aggressive driving applications. Common problems involve the engine, transmission, and the rear suspension.

Last month I was in the area with a couple of my kiddos when my car started acting up. I was too far from my usual mechanic and started getting quite concerned as the car was telling me to shut it off. I called around 7-8 auto shops and received the same answer 'too busy', 'almost closing time' etc. I finally got a hold of the guys at Gilmore and they were able to see me right away, even if they were closing soon. They found the issue, fixed it quickly, and checked on me after ward to make sure I made it home safe. If that's not service, I don't know what is. Go see the workers at Gilmore. They'll take good care of you.

After moving to Walnut Creek I was in need of an auto service repair shop; through a referral I started taking my car to Gilmore's. Over the last year or so I have needed to take my car in for a one or two issues as well as basic oil change & have been very happy with service. They are very thorough in their work & have been really good on keeping me updated on repairs or service in general. They also are good about following up and checking in after service has been completed to make sure everything is in working order. Everyone I have interacted with is very friendly and accommodating. Josh especially is really great. Although their service fees are a bit higher than those I paid at my previous shop, I feel like I'm getting my money's worth. If you're looking for a good Auto repair shop, I definitely recommend Gilmore's!
