Gas Recirculation Valve (egr Valve) problems of the 2019 Chevrolet Equinox

The contact owns a 2019 Chevrolet Equinox. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed and went to the floorboard, but the vehicle hesitated to accelerate before lurching forward. Additionally, the vehicle lost motive power while driving 60-70 mph and decelerated to 10 mph. The engine revved while stopped at a red light, and the rpm was at high. The check engine warning light was illuminated. The contact stated that the vehicle was taken to the dealer on six occasions for the recurring failure. The contact stated that dtc: p0401 and p0521 were retrieved and cleared after securing the air box cover after the first failure. The second time, the egr housing was clogged with carbon, and the oil sensor failed internally and was replaced. The third time, the wiring harness and unknown sensors were replaced. The fourth time, an unknown sensor and module were replaced. The fifth time, the dealer replaced the transmission with a used transmission, but the failure persisted. The vehicle was then taken back to the dealer, and it was determined that the driver's side cv axle seal, nox sensor 1, maf sensor, passenger side front wheel bearing, two front tires, four tpms, intake manifold, and air temperature sensor mount needed to be replaced. The manufacturer was made aware of the failure by phone. The failure mileage was approximately 89,000.

On may 18th 2019 while accelerating from 45 to 65 mph to enter onto a freeway, heard/felt loud pop from engine, lost power warning lights appeared "reduced power". Contacted on star, noted the problem drove to dealer 8 miles away, diagnosed as plastic clamp on hose from turbo charger broke. Equinox had 732 miles on it, in shop for 14 days waiting for fix. Metal clamp added to re-enforce the plastic clamp, dealer stated new hose ordered as still defect in the plastic coupling. August 7th, back at the dealer to install new tube for turbo charger. August 13th driving 45mph, accelerated lightly maybe from 1600 rpm up to 2500 rpm, felt/heard pop from bottom of engine same warning of reduced power. Same issue as before, different part of the tub from engine to turbo charger. This is a defect in engineering, need NHTSA to step up, order gm to fix this properly. No longer trust this vehicle. Still summer here, will be very unsettled during the winter when temps can stay below 20 degrees for weeks or colder how a plastic tube will react to the cold in a hot engine compartment. Nhtsa needs to act now before this causes accidents with injuries or death because of negligence on the part of gm and those engineers that designed this weak system. This what a government agency is supposed to do, protect the consumers. We purchased a new vehicle to drive not be worried if it will get us safely to where we need to go!.
