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.

I own a 2019 Chevy Equinox LT 1.5L and am experiencing the exact symptoms described in GM recall 18V576000. After 1–2 hours of driving, the rear brakes begin to drag, creating hesitation during takeoff. The issue resolves after the vehicle cools down. Both my mechanic and independent research confirm this is the same safety defect described in that recall, but my VIN is not included.

While driving, the vehicle went into Engine Power Reduced mode, check engine light went on, and the Brake Assist notification came on. I pulled over and turned off the vehicle; vehicle would not restart. Had the vehicle towed for diagnosis; told initial codes were timing issues. Vehicle has 83,000 miles and showed no evidence of any sort of failures - no warning lights, no brake issues, no hesitation, no unusual sounds, no rough idling or driving. Dealership stated the vacuum pump failed and broke apart into the camshaft and into the engine. Official diagnosis was new vacuum system and engine replacement for a cost of $14,000.

I have had my vehicle in for repair three times for an EVAP code. The first visit they found nothing wrong. The second visit they placed the EVAP canister. The third visit they said if the light comes on again it's a faulty part. The light is on again. Since the first occurence, I have noticed the some of the same issues that were reported for the 2020 Equinox fuel pump issues, e.g. hesitation, choking,

While my wife and I are traveling on the highway out of town going 72 mph there was traffic and she began to press the brake peddle but car didn't want to stop. She had to push all body weight on the brakes and the brakes seem like it's hesitation and vibration but eventually stopped. This is very dangerous and brake service light came on. I pull off the exit and check fluids and brakes and all looks normal as I know some about cars. I called to get it checked today and lady said to bring it in right away as they are aware of this common issue with these equinox. She say either canister or pump failure which I researched and have many people who have complained but GM has changed 2018 certain models but failed this model year also and didn't fix the design for this model year of 2019 D2. Need this investigation to continue and I will begin petition for class action suit against GM which they have been notorious for law suits. Please help!!!

Auto stop / start is going to get someone killed. Hesitation from brake to gas causes a whiplash effect to everyone in the vehicle. Also, pulling out in traffic is a total crap shoot as to weather the vehicle is going to start, hesitate or go at all.

The auto stop engine feature has no control device to disable the feature. Auto engine stop causes the vehicle to lurch forward when restarting from the auto stop condition at traffic lights. I have also experienced hesitation of the restart condition when making a left turn at a busy interesection causing myself slight panic when trying to accelerate to complete the turn with oncoming traffic approaching. Very dangerous! This feature should be allowed to be turned off by the owner especially when driving in rush hour traffic. Safety is more important than fuel consumption.
