2020 GMC TERRAIN — Problems, Recalls & Safety Data

The contact owns a 2020 GMC Terrain. The contact stated that while driving in cold weather at various speeds; moisture accumulated and deactivated the charger, causing the vehicle to go into LIMP Mode and lose drive power. The vehicle was taken to the dealer, who diagnosed the vehicle and determined that the charger air cooler was defective and needed to be replaced. The dealer also wanted to place an air deflector on the vehicle. The contact was informed of a service update for the failure however, the VIN was not included. The vehicle was not repaired. The contact researched and learned that in Canada, the issue was being remedied with a bra apparatus and a thermal wrap for the engine to prevent the failure. The manufacturer was made aware of the issue and confirmed that the VIN was not covered. The contact was waiting to hear from a supervisor. The failure mileage was approximately 140,000. The VIN was unavailable.

I own a 2020 GMC Terrain with approximately 110,000 miles. While driving in winter, the vehicle suddenly lost cabin heat and defrosting capability. The temperature gauge began fluctuating and the cooling fans continued running after the vehicle was shut off. A mechanic diagnosed the cause as a cracked radiator that allowed coolant to leak out, which is a known frequent failure on this model. Because the heater stopped working in sub-freezing temperatures, this created a safety hazard due to lack of defrosting and heat while driving. The failure occurred without warning, and no coolant warning light was displayed before the heater stopped working. The vehicle was not overheating at the time, but the loss of heat and defrost made winter driving unsafe.

I noticed a sticker in driver door stating recall however no evidence. The vehicle will not pull hills, back up on a hill and will not accelerate over 25 miles per minute. Dangerous to drive on roads. Took vehicle to a GMC dealer for diagnostic test, received the report for what the report found. Took the report to auto shop to get repaired however the vehicle still continues with same issue. Took the vehicle to another auto shop. I was informed of some differences added issues. I had those issues fixed. The vehicle still running the exact way after all of the repairs. The top hood on the vehicle paint starts peeling after a year of owning it. I purchased the vehicle at Kia of Gardendale 2020. No one had any answer regarding the situation. Very disappointed with a GMC vehicle. I just want to know the mystery.
