2023 Chevrolet Equinox

The fuel pump on my 2023 Chevrolet Equinox began malfunctioning on [XXX] when the check engine light came on. Less than 24 hours later, the light went out. On [XXX], while leaving a CVS pharmacy, the vehicle jerked, then the engine shut off. After putting the car in park, I was able to restart the car and continue on. On [XXX], the check engine light illuminated again. While sitting at a stop light in the turn lane, as I began to push the accelerator, the vehicle once again jerked and the engine shut-off, almost causing the vehicle behind me to collide. I was able to restart the car and continue on my way. On 3/21/25, I took the car to the local Chevrolet dealership (Integrity Chevrolet in Chattanooga, TN). After inspecting the car, the dealer informed me the high-pressure fuel pump and fuel pump module was bad and had to be replaced. The service manager agreed this failure was not the result of operator error and should NOT have failed after only 2.5 years of normal use. The conditions/symptoms are almost exactly the same as those described in GM recall notice N222372310 (dated 5/23/23). The repair cost $1,113.46 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2023 Chevrolet Equinox. The contact stated that while driving on several occasions at various speeds, the vehicle stalled. The vehicle was restarted after two or three attempts each time. The check engine warning light was illuminated and the OnStar app notified her of fuel issues. The vehicle was taken to a dealer where it was diagnosed that the high-pressure fuel pump and the feed pipe needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 37,000.

Traveling 75 mph on a 3-lane highway when the car jerked (as if it was downshifted), started to rattle, and then ultimately a CE came on with the "Engine Power Reduced" warning on the dash. After a few close calls trying to merge over to the breakdown lane, I was able to rest safely and call for a tow. Unable to turn the car over after a few attempts, the car finally started back up after 5 seconds of cranking. Tow to certified Dealer where they confirmed 4 codes were being presented by the car. The codes are: P0089 - fuel pressure regulator performance P00C6 - fuel rail pressure low during engine cranking P228C - fuel pressure regulator 1 low pressure P0171 - fuel trim system lean The Dealer was unable to replicate the issue and is unable to fix or repair any part. Clearly, there is an issue with the Fuel Pump in these '23 Equinox's - just like the past model year!

While attempting accelerate on the highway at 70 MPH the car entered "Engine power reduced" mode resulting in the car to slow down. This reduced speed resulted in a few near misses on the highway. The check engine light than began to flash for about 15 seconds before all the messages went away and normal driving conditions occurred. Taking it into the dealership they pulled from the computer the issue of "multiple cylinder misfire" but could not replicate the issue. I also filed a ticket with GM letting them know of a potentially deadly issue but they sided with the dealer stating the car was operating within normal parameters since they could not duplicate the issue. The weather prior to the issue was rainy.
