GMC Complaints

I HAVE A 5TH WHEEL WITH SOLAR AND MY BRAKE CONTROLER STOPS WORKING PERIODICALLY. I HAVE A CASE# WITH GM 9-13676268071. I ALSO HJAVE AN EXTENDED WARRANTY WITH GM AND IT'S NOT COVERED DUE TO MY VIN# NOT BEING ON A BULLENTIN# 23-NA-149. GM ALSO HAS A CUSTOMER SATISFACTION PROGREAM # N232414840 AND STILL WON'T COVER IT. THIS IS A MAJOR SAFETY ITEM AND CONCERN FOR ME.

Driving on highway and engine cut off with no warning. No dash lights to show a warning. 3321 miles on engine. The vehicle was unable to be put in neutral for the police to push it out of the highway. Three Moncks Corner police cars surrounded the vehicle to maintain safety. The vehicle was towed to the dealership. Needed a new engine and cooling system. The engine and cooling system were both replaced.

I bought a 2003 GMC Envoy 3/23/24. The main frame and sub-frame have extensive rot, and is unsafe to drive. It is available to inspect. They disguised frame damage and sold me an unsafe vehicle. I brought the car in to have the ac repaired in August 2024 and when they put it up on the lift that's when they saw the damage. This was Rogers Automotive in Westport MA. They told me at that time that it is unsafe to drive. It has not been inspected by any other parties at this time. We had no idea it was damaged, Rogers said it was sprayed to try to hide the damage.

A large trim piece at the top of my grill flew off while driving 70+ on the highway. I have personally seen roughly 100 testimonies with picture proof on various fb pages of others with the same vehicle experiencing the same thing. This is a known issue for the 2022-2023 model years, GM has apparently corrected the issue for the 24+ model years.

Serious Safety Issue: While driving in the Rain, with the wipers on (actively working), randomly they will stop working. They will not work again until 10-15 minutes of time has passed. Any alternative setting makes no difference. During the 10-15 minutes of non-working wipers, there is nothing the driver can do…. Except wait. Depending where and when this occurs, this could be a deadly safety issue. I’ve checked the fuse; Turned off the rain auto-sensing feature – yet the vehicle is scary to drive in the rain, not knowing if / when the wipers may stop working again. During my ownership of this vehicle, this has happened three times; of course you must be driving during rain for the issue to occur.
