When merging onto the interstate, the vehicle lost ability to shift, started lurching and would not accelerate. No prior transmission issues had occurred and the sudden loss of shifting capability was a significant safety risk. This was GM Case# 89525980 The Transmission Valve body assembly was faulty and gave out with no warning. It had to be towed into the GM dealer and repaired for $2519.79

The vehicle experienced multiple instances of sudden engine stall and loss of motive power. These failures occurred without warning, leaving the vehicle immobilized in high-traffic areas, including a turn in a multi-lane roadway. This defect creates an unreasonable risk of a rear-end collision or being stranded in hazardous traffic conditions. Incident Chronology: Initial Failure: In April 2026, the vehicle stalled in an intersection. After a manual reset of the Check Engine Light (CEL), the vehicle stalled again during a turn. Diagnostic codes P228C (Fuel Pressure Regulator 1 Exceeded Control Limits) and P0089 (Fuel Pressure Regulator 1 Performance) were present. First Attempted Repair: The dealership performed a Technical Service Bulletin (TSB)/recall procedure to calibrate the fuel pump and pressure sensors. Recurrence: Immediately upon retrieval, the vehicle stalled again. The vehicle would not restart or maintain idle, necessitating a second tow. Final Repair: The dealership recalibrate the module. Additional Safety Concerns: the vehicle experienced multiple "Reduced Engine Power" events and "Check Engine" flashes while traveling at highway speeds (approx. 70 mph). Manufacturer Response: Despite the "Engine" designation of the diagnostic codes, GM initially claimed the fuel pump was not covered under the powertrain warranty. While partial assistance was provided for repairs, the recurring nature of these stalls suggests a significant reliability issue with the high-pressure fuel system components and engine. After purchasing 4+ Equinox's within the last few years without any issue this is the worst experience I have had thus far.

Odometer Fraud. The contact purchased a 2018 Chevrolet Malibu. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 93,000. The contact stated that while attempting to trade the vehicle with the dealer, the dealer declined the trade due to a possible odometer fraud. The dealer discovered from the Carfax report that the mileage was 98,000.

The transmission failed, shifting is no longer smooth. It hesitates and shakes the entire car, and the car slows down to almost a crawl uphill. I understand this is an issue with Chevrolet Impalas. So now I have an $8200 bill for a problem I was never told about, and that GM knew that it existed. So, yes, the issue has been identified, reproduced and confirmed by the dealer. The warning light came on when the issue happened, so it was already too late. The issue began with just over 65,000 miles. So I have a 2018 Impala in almost perfect condition in need of an $8200 before taxes, transmission replacement. I would like some help from the NHTSA, like requiring GM to pay for the repairs. Thank You very much.

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.

I have a problem with parking, the warning comes on,”Shift Into Park” knowing that I’m in park, so it’s not registering. Have to move the shifter a couple of times before it comes off. My check engine light stays on and then comes off a week or two later and then comes back on and no code comes up, so I’ll clear it or let it clear itself.
