  • 2021 GMC ACADIA
    - Melvin Village, NH

    No matter what speed I am driving at or whether or not there is a passenger my service safety restraint system light comes on randomly and shuts off randomly. I called the dealership and they brushed it off saying it just means the airbag wont deploy if I were to get into an accident. Great thanks that makes me feel real safe! I see several people complaining about this as well and think it might be time to look into what the problem is and do a recall.

    - Dallas , TX

    While I’m parked or even driving I keep getting a alert on my speedometer ( Trailer Break System ) and it’s not a 1 time alert the whole time I’m driving it’s constantly alerting me yet I don’t even use my Trailer system at all, it’s concerning due to the distraction of trying to clear the screen constantly while I’m on the high way.

    - Gulfport, MS

    The transmission/torque converter is causing (bucking, kicking, jerking, slipping, difficulty when taking off, shuddering during driving, fishbite, and chuggle). Its becoming a safety hazard now because its putting me and others at risk for an accident. The vehicle will hesitate to go in which if traffic may be rear ended by another vehicle. During weather/rain the vehicle will lose traction and the rear wheels will spin causing an accident. Problem has been reported to dealership multiple times and the only solution they can provide is keep driving the vehicle. Vehicle has no warning lights at all or any other symptoms of problems prior to when the components started to fail. The issue first happened around February 2024 and remains to be an issue to this present day. I've been the dealership more than 6 times with no solution/fix. I'm concerned for my safety now and need this issue addressed ASAP.

  • 2023 GMC SIERRA 2500
    - Flora, MS

    The valve body inside the transmission has failed and GM has known it to fail but they have done nothing about it. My vehicle has been in the shop for 2 months because of it and “parts are on back order” it’s terrible i’ve bought this vehicle in august and it’s constantly been inside the shop for various issues. My transmission lost 7th gear and it came to an immediate stop in the road because of it. tires screeching and all. truly embarrassing that you can spend 83,000$ on a truck and it be such a peice of junk.

  • 2014 GMC SIERRA 1500
    - Mayfield , OH

    The frame of the vehicle is rusted through in 2 areas. I recently noticed the rusting frame. Shortly after I purchase the vehicle the rust preventative coating, that was factory applied, was noticed pealing from the frame rails. I sprayed undercoating on the frame at that time to avoid rust after seeing that the factory application had failed. This has not been adequate as the frame has rusted in an area that the inside channel of the frame did not drain effectively and therefore collected water and salt during the winter months. The frame cross members are also rusting badly. The metal is flaking off excessively. In contrast the trailer hitch on the truck is in very good condition because it is the only part of the frame that appears to be properly conditioned to resist corrosion.
