While driving my 2020 GMC 2500 Denali with the Duramax Diesel engine, the power assist for the steering and brakes failed without any warning. This made the truck nearly impossible to steer and stop. Luckily, I was able to avoid a collision and get the truck stopped in a safe location. The truck is currently being towed to Rivard GMC in Tampa, Fl. Doing an internet search, I found this problem has happened to others as well. Please ask GM to rectify this extremely dangerous defect.
The vehicle pulls to the right or left into oncoming traffic within 800 feet or sooner depending on speed. This occurs on city streets or interstate. GM and GM approved dealerships say this is done to GM specifications. The first 7000 miles, it didn't pull. After GM shop aligned, and 3 months later, it is unsafe to operate.
