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 premium, reliable truck — instead I’ve gotten nothing but frustration, expense, and stonewalling from both GMC Delray’s service department and GM Customer Service. Owners across forums and Duramax community boards have been reporting 10-speed transmission valve body failures that lead to harsh shifting, torque converter shuddering, and even limp mode or lockup conditions. These issues aren’t rare anomalies — they’re well-documented complaints from GMC and Chevy owners with similar model years.  My truck began sputtering and shuddering under load, a classic symptom of torque converter and valve body problems that many others have also documented online. Despite my visits and clear diagnostic results showing failures directly tied to the transmission’s valve body and torque converter, GMC Delray refuses to classify the damage as a defect worthy of warranty coverage. They’ve told me the damage isn’t covered and wants me to pay for work that is clearly tied to a known failure trend. Other owners have experienced months at dealerships waiting on backordered valve body parts, or being offered only software updates that don’t fix the underlying failure.  To make matters worse, GM Customer Service has been dismissive, offering platitudes but no resolution, not standing behind their product, and forcing owners like me to fight for coverage that should be automatic under powertrain warranty. This has been an expensive, drawn-out nightmare. Based on my ordeal and the countless similar reports from real owners, I can no longer trust GMC or GM to honor their commitments. Avoid dealing with Delray’s “service” department unless you want endless excuses and zero accountability. (If you are experiencing the same concern I am there is a class action suit regarding the 10 speed transmission) Contact information at GM Service manager Ralph Nahmod Assistance service manager Dave Glickatein Master service consultant Casey Salman More

I recently bought a new truck from Delray GMC and wanted to add a bed cover to the vehicle. We ordered the cover and went for the appointment, we decided to wait while they installed. Two hours later the to add a bed cover to the vehicle. We ordered the cover and went for the appointment, we decided to wait while they installed. Two hours later the service manager came out said they ordered the wrong one it would not fit. Accidents happen the two hours was kind of ridiculous but understood. Drop the vehicle off the second time to get the cover installed and when I come back to pick up and pay for the service the price has gone up $600.00, I ask to speak to the manager and he says let me see what I can do he says he can drop the price $200. I am not the type to argue or throw a fit, I pay the bill and leave. I have a written quote from the dealer showing the price of the cover and the install and they basically bait and switched me. When I bought the truck the sales rep was nothing but professional and courteous I did not haggle on price or terms. The service department is not the same to provide a written quote and then change after the fact is wrong. On top of the poor experience the install was not up to the standards you would expect of a GMC service department. They screwed holes in the bed of the truck (that were left unfilled) for no reason, and installed drain tubes in the middle of the bed so you can't slide anything to the back of the bed. More

Service Department sucks… 4 hours wasted and don’t trust diagnosis that took 4 hours and no one had even touched underside of vehicle…I checked…furthermore service has been lackluster nearly every time I’ve diagnosis that took 4 hours and no one had even touched underside of vehicle…I checked…furthermore service has been lackluster nearly every time I’ve opted for using the service dept. GMC warranty sucks …known problem with transmission serviced 1st with fluid change several years ago, then torque converter changed some time thereafter and was out of warranty because they probably should have changed torque converter instead of just the fluid the first time. Same problem is 3rd time now. Now torque converter and valve body they tell me needs replacement…and once again out of warranty with 68000 miles on vehicle total. Just was diagnosed from computer apparently because underside of vehicle was never touched…I looked… So GM warranty replacement torque converter only for one year?…I guess the new torque converter on new vehicle only warranty is one year too?… When replaced last time I had to wait three weeks for a gm part even after I offered to pay and deliver an upgraded/ superior aftermarket unit. Last issue on last oil change visit was check engine light I wanted addressed. Code showed due to MAF sensor code and was told to change air filter…air filter was relatively new but replaced anyway resulting in same code. Service department never even offered to change sensor…I Changed MAF sensor myself-problem solved. Service department nearly worthless except when stealing change and contents of vehicle it seems. I will never deal with this dealership or service department again…told my salesman that I’d love to buy another vehicle from him but unless he finds new brand and dealership there is no chance. xxxx on GMC, this establishment and service department. It won’t be a GMC to replace this truck…ever… You should add xxxx poor rating to your choices below for this dealership… More
