by 2024 GMC TERRAIN DENALI Shopper on 03/24/2026Verified Purchase
For the first time in my life I bought a car online sight unseen. What was a stressful decision was made smooth and comfortable by the team at Timbrook, particularly my salesman Brian Read. To date the car is as advertised and I was treated with respect.

The price of a new key fob was pretty high. The service department did not call me when the part came in. I had to call them. I brought the broken key fob and was told that it would work after they created the new one. It does not turn on the car. The new one works fine.The process took about an hour. I had no other options in my area to have this service done.
by 2024 GMC SIERRA K1500 DENALI Owner on 12/04/2025Verified Service
My motor blew in my Sierra Denali (L87 engine recall) and i had it towed to Timbrook as it was the closest dealer and i was 200 miles from home. THeir service was awesome, communication was top notch and they handled all communication with GM. My contact in service, Ken, was an absolute pleasure to deal with. I think they even detailed my truck before they sent it back to me. Highly reccomend Timbrook GMC!!

by 2016 BUICK LACROSSE PREMIUM Owner on 05/31/2026Verified Service

by 2023 GMC TERRAIN SLT Shopper on 05/21/2026Verified Purchase
Everyone was so informative and personable. Very patient with my indecisive thinking. Tried 3 vehicles and the one I picked is perfect!
by 2019 GMC SIERRA K1500 SLT Owner on 05/02/2026Verified Service
Convenient drop off option the night before my scheduled appointment allowed for a quick and easy return the next day. Maintenance completed as requested.
by 2017 GMC YUKON DENALI XL Owner on 04/24/2026Verified Service
Always a great experience at Timbrook Service! A special shout out to Ken and Devin for always hearing my concerns and explaining repairs needed.
by 2017 HONDA CIVIC LX Owner on 04/08/2026Verified Service
Timbrook is the worst place to go. It took them 5 months to do nothing to it while we struggled to get around without a car then they "totaled" the car.
by 2004 CHEVROLET IMPALA SUPER SPORT Owner on 02/15/2024Verified Service
Service at Timbrook Automatic is always excellent. The service department employees are always efficient, polite and very friendly. I never have any complaints about them at all. This is my go to place for service on my Chevy Impala. As you can see my car has very high mileage and Timbrook keeps it in good condition.
by 2015 BUICK ENCORE CONVENIENCE Owner on 05/01/2023Verified Service
I previously had a great experience with the team at Timbrook. Lately, I've had a recent recurring issue with the turbo in my Buick Encore and they haven't resolved it yet. I was told a new turbo was being ordered and today was told it just needs an oil change.
by 2013 CADILLAC SRX PREMIUM COLLECTION Owner on 09/30/2022Verified Service
Was a little disappointed because this was my second service and no one had anything to say about my tires and when I asked they told me they were shot. So I was a little upset had vehicle for 9 months and had to invest in new tires. On Timbrooks defense they did instal my tires at no cost.
by 2016 CADILLAC ESCALADE LUXURY Owner on 08/16/2022Verified Service
AS FAR AS SERVICE WORK WENT, VERY PLEASE .... GOOD TURNAROUND TIME AND CURTIOUS ...... SECONDARY WORK SUB CONTRACTED TO OUTSIDE SOURCE (WHEELS) NOT VERY HAPPY ... VERY POOR WORK PREFORMED AND SURPRISED THAT DEALERSHIP WOULD ACCEPT THIS KIND OF POOR QUALITY ..... HAD MORE RESPECT FOR THEM THAN THAT
by 2003 FORD FOCUS LX Owner on 11/05/2018Verified Service
they did a decent repair but charges me for it, I should have received a discount i feel due to having the same work done on 1/9/15. and at less than 15000 miles. but the exhaust is not falling off they said it was normal wear and tear, thats funny i have owned lots of cars and they never go out like that under city driving.
by 2016 DODGE JOURNEY SXT Owner on 09/09/2017Verified Service
Service was very friendly and fast. I was done within 30 minutes and thats a super plus with 4 children. They also gave my children candy. While my notification didnt reset I went back the next day and the gentleman looked up how to do it and came out and reset mine.
