GMC Complaints

Today August 22, 2023 at 2:30pm, just about to leave work home when I received a message on my dash board telling/showing me "Service Trailer Brake System". And that sign kept coming on every second all the way home from work, couldn't heard nothing else that us going on inside the car like my phone, radio, turn sign, etc..

the radio control panel seems to quit working every 2 years. This will be the 3rd radio control panel that I have to replace in this car since 2017. GMC says it isn't their problem since they use other products than GM. I feel that GM motors should stand behind the products that they place in their cars. The same product breaks the same way every time, This is not a me problem but a GM problem.

The frame on my 2014 GMC Sierra pickup is rusted through on the driver’s side cab area. A truck frame should last longer than 9 years old. Is GM going to do anything about this problem?
