I purchased my 2020 GMC Turbo Diesel and expected a premium, reliable truck — instead I’ve gotten nothing but frustration, expense, and stonewalling from both GMC Delray’s service department and GM Cus More

We’re sorry to hear how frustrating this experience has been for you. We do want to clarify that our team has advocated on your behalf. We were able to secure substantial help on your recent visits, even though your warranty had expired. Most recently, on 1/30/2026, we again obtained 60% coverage toward the transmission repair to reduce your cost as much as possible. We recognize that your concerns relate to GM’s broader manufacturer policies, and we’re sorry that this has added to your frustration. We remain committed to helping you in any way we can and are here to assist with any next steps.

I understand you guys offered 60% for a faulty part that GMC caused. My question to you is show me all your extended warranties GM provided your dealer regarding transmissions issues. I know how you guys tweaked the numbers, especially in the warranty and service department to gain profit for the dealership. If you can be transparent, I would accept your offer. I’ll be waiting for your response.
