Reviewed by John DeLeon from Santa Maria, CaJune 20, 2025

I had a fantastic experience purchasing three trucks from this GMC dealership—the sales team was professional, helpful, and made the process smooth. However, my experience with their service department has been extremely disappointing due to consistently poor customer service. They recently introduced a texting feature to keep customers updated on service progress, which sounded promising. Unfortunately, it’s completely ineffective. Every time I respond to a text with a question or for clarification, I get no reply from the service advisor. It’s frustrating to have a system that seems designed for communication but fails to deliver. Additionally, when I call for updates, the staff come across as grumpy and short-tempered. They seem annoyed by basic questions about my vehicle’s status, which makes the experience feel dismissive and unprofessional. This lack of responsiveness and poor attitude have been consistent across multiple visits. While the dealership excels in sales, the service department’s customer service needs significant improvement. I hope they address these issues, as it detracts from an otherwise positive experience with the dealership.
