2024 Chevrolet Equinox

I was turning at a green light while following behind a truck pulling a trailer. All of the sudden, the car did the automatic emergency braking. It slammed on the brakes in the middle of an intersection while I was going ~15mph, and gave me whiplash. I am not sure if the car got confused by the trailer in front of me, but this is the first time this has happened in my first few weeks of owning this car. I've read that many others have had this issue with the Chevrolet Equinox EV, and this poses a serious safety issue for drivers of this car and others on the road.

Subject vehicle has 11919 miles. The vehicle is less than three years old and covered under factory warranty. While driving 35MPH, engine suddenly did not respond to throttle. This engine stopped. Driver was able to coast to roadside. After OnStar analysis, engine control computer logged code 'P129F - An issue has been detected in the Fuel Management System used to maintain, control and monitor fuel consumption'. After towing to dealer, part number 13554821 was replaced. There were no prior warnings. The engine just stopped and would not restart. This is a major safety concern. This incident occurred 10 minutes after exiting the highway (65MPH). Having your engine stop unannounced at any speed in traffic is not safe, especially in high traffic and high speed situations. Dealer service nevertheless indicated this particular problem and part is well known but not considered a safety issue by the manufacturer. We disagree.

Check engine light with message engine running at diminished capacity as speed would not go above 20mph. Safety at risk from other vehicles on highway until able to reach safe location. Dealer states SES light on P0089 and P228C. GM bulletin on both codes. Programmed ECM with latest calibration for codes listed. If codes come back must do further diagnostics. Concerned about repeat possibility.

The contact owns a 2024 Chevrolet Equinox. The contact stated that while driving approximately 35 MPH, there was a loud ticking sound coming from the engine compartment, and the vehicle started jerking, vibrating, and decelerating before it stalled. The vehicle was towed to the local dealer to be diagnosed. The vehicle was diagnosed with bearing and push rod failure. The contact was informed that the engine needed to be replaced. The engine was replaced, but days later, the contact discovered engine oil was leaking from the vehicle onto the driveway. The vehicle was driven back to the dealer, who discovered a pinhole in the engine intake manifold, which had caused the engine oil leak. The intake manifold was replaced, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 9,600.

My car seized while I was driving. It started fine and I drove about 10 min down the road and all of a sudden it seized. My car was towed to dealership. OnStar sent me a code p129f fuel pump. I was driving on the road and it seized. Could have caused a bad accident. Cars had to go around me. Yes the problem was “fixed” today 6/30. No prior error messages after is seized my battery light came on

The transmission lurches and shakes violently when under pressure such as times when trying to accelerate onto a highway. I recently was traveling and had to enter numerous highways and each time the transmission was extremely jerky and I felt it may fall out of the car at some points. Once I was trying to get on to the highway and a tractor trailer was coming up behind me and I literally have to pull off to the right because the car would not accelerate and was jerking violently. I've had it to Chevrolet service three times and each time they tell me it's normal which I know is absolutely not true.

2024 Chevrolet Equinox EV. Beginning approximately two infotainment software updates ago, the vehicle's Bluetooth system repeatedly drops the connection to my paired iPhone, and the contact-sync feature stopped functioning entirely. The problem did not exist when the vehicle was new and started only after a vehicle software update, indicating a software-introduced defect rather than a phone fault. I have reset the infotainment system and performed a full delete-and-re-pair on both the phone and the vehicle; the dropouts and contact-sync failure persist. Because the system no longer reliably supports hands-free calling, I am unable to consistently place or receive calls without handling the phone directly while driving, which I consider a driver-distraction safety concern. No warning was issued and I am not aware of a recall or software fix addressing this.

Less than 2 years old and under 50k miles. Car began to sputter and then shut off - no warnings received until the car shut off. Once able to turn back on (approx. 10 minutes) car went into limp mode. Was able to drive to a dealership where they received codes for fuel tank with no visible issues through a thorough service at the dealership. Dealership reprogrammed the car and indicated codes could replicate and require a new fuel pump.
