2023 Chevrolet Equinox engine problems

ENGINE

The ongoing issues with my 2023 Chevrolet Equinox, VIN [XXX], which I have brought to your dealership multiple times for the same unresolved problem. I was told three separate times that the engine light was fixed. I checked the vehicle today, and the engine light is still on. I was misled three times. Since purchasing this vehicle, I have not been able to drive it. Instead, I have spent the last four weeks repeatedly picking up and dropping off the car at your dealership. The vehicle has spent more time in your service department than with me. This has caused significant loss of time, money, and peace of mind. You have wasted my time, energy, and resources, and your team has already put 95 miles on my vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

NHTSA complaint #11758877 — an unverified report by a vehicle owner.

ENGINE

The vehicle is experiencing repeated, sudden engine stalling while driving at speed, creating an immediate risk of a severe traffic collision. In March 2025, the fuel pump failed and was replaced by an independent mechanic, who later had to clear a system clog in August 2025 after a second stall. In August 2026, the dealership replaced the fuel pump under an official NHTSA safety recall. Within days of receiving the vehicle back, the new recall remedy failed, causing the vehicle to stall in traffic again and nearly cause a major accident. The vehicle has suffered four separate fuel-system-related failures/stalls under 87,000 miles. The manufacturer's official recall remedy has failed to resolve the safety hazard, and the vehicle remains entirely unsafe to drive.

From the very first day of purchase, the vehicle displayed a check‑engine light, which I immediately pointed out to your salesperson. My concerns were dismissed, and I was assured that it was “not a big deal,” despite the fact that the issue was clearly present at the time of sale. Since then, I have spent substantial time and money attempting to resolve the vehicle’s defects. A mechanic spent six hours diagnosing and attempting repairs, yet the vehicle continues to display serious fault codes, including: EVAP System Switching Valve “B” Performance / Stuck Open DC/DC Converter Voltage Sensor “A” Range/Performance

My 2023 Equinox RS losses power during quick acceleration for lane changes or passing. It will also lose power during some turns at normal speed. It will also accelerate and deaccelerate at a low speed making it feel like the gears are slipping. Auto stop on occasion will be a hard take off requiring a firm foot on the brake. At time it will also shift hard into 1st gear. My car has been in the dealership three times for this issue and the last time the tech said there was a recall for the issue and performed some reset and gave me the car back. Other than that they said there is nothing they can do about it. This issue presents a major safety issue especially when it losses power during a lane change or passing someone. I can't anticipate when the power will come back and by that time the traffic has now caught up to me. This problem started probably 6-8 months after I purchased the car new from the dealership.

I was driving on freeway and went to pass a semi. The suv hesitated and had terrible turbo lag. It almost caused an accident if it hadn’t been for the truck behind me taking action to avoid a collision.

Recall/Loss of Power I am filing a safety complaint regarding a 2023 Chevy Equinox. The vehicle began losing engine power and will not go over 40 mph. This creates a dangerous driving situation because the vehicle cannot maintain highway speed. The vehicle has a fuel system recall, and the issue appears to be related to the fuel system. The vehicle is currently at a Chevrolet dealership and has been there for almost a month. The vehicle is currently inoperable. This is a safety concern because loss of engine power while driving could cause an accident. I am requesting that this issue be investigated as a safety defect.

The contact owns a 2023 Chevrolet Equinox. The contact stated that while driving uphill, the vehicle lost motive power with the check engine warning illuminated. The contact immediately depressed the accelerator pedal, and the vehicle accelerated, and the light turned off. The vehicle was taken to the residence. The contact stated that two years later, while driving approximately 40 MPH, the check engine warning light illuminated. The vehicle was taken to a dealer, where it was diagnosed, and determined that the fuel pump needed to be replaced. The vehicle was repaired but the failure recurred 9 days later. The contact believed that the failure was associated with an unknown recall. The manufacturer was notified of the failure. The failure mileage was approximately 44,200.

ENGINE

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)

ENGINE

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.

Getting vibration and loud noise at 35 to 40 mph since taking delivery. Have contacted dealership and they are waiting for GM to respond. I have seen similar complaints about drive line and drive axle complaints for earlier model year Chevrolet equinox.
