I worked with Bill in order to get the telematics module

Reviewed by paulfambriniFebruary 09, 2026

I worked with Bill in order to get the telematics module fixed in my GMC Sierra EV. Bill was extremely helpful throughout the whole process and kept me in the loop the entire time. I was able to get my car repaired in 4 days. Whole experience was great.

We are so thankful for the incredible service we received

Reviewed by RancherlewisFebruary 09, 2026

We are so thankful for the incredible service we received from Alpine GMC thanks to Sergio Gonzalez. He went the extra mile to facetime us and allow us to look the truck over before we made the 3+ hour drive to see it in person. During the pre-delivery inspection they discovered an issue that needed to be resolved with an out-of-stock part, which meant we couldn't go home with it. However, after the part came in and the problem was resolved, Sergio delivered the truck to our home and even brought a HUGE red bow for us to take pictures. We were extremely impressed with the integrity, honesty and kindness we were shown. We will definitely be back!
