Buick Envision fuel pump problems

Filed Oct 1, 2026 · Fuel system · WV

My 2022 Buick Envision is experiencing sudden engine stalling while driving and intermittent failure to start. This creates an immediate safety hazard as the vehicle loses power unexpectedly in traffic. This vehicle matches the exact year, model, and defect described in GM EMISSION RECALL N25216900(Fuel Pump Power Control Module). However GM corporate is refusing to cover the repair under the recall because they claim my VIN is not yet active in their ‘phased launch’ system. The vehicle is dangerous to drive and currently has only 32699 miles. I had on-star to do a diagnostic and they gave me 2 critical red error codes…P102B and P129F

Parked a running vehicle, 2023 Buick Envision with 52000 miles and when I went to start the car again, it would not run; cranked OK but would not start, just "stumbled" for a few seconds and then nothing. Tried several times thereafter to start to no avail. Called for a tow and learned that due to a not running vehicle that has electronic transmission, could not put it in neutral to allow a simple tow; tow driver had to put dolly on both front wheels and rear to tow to GM dealer. Original decision by service rep was that the fault was due to a bad fuel pump module. I called GM for any recall on this model and device only to hear that it was not a problem for them to present a recall. I am not the first customer that has had this problem according to your website and number of complaints with the same make, year, and model of Buick.

I started the car. Backed out of my driveway. Put into drive. The car stalled I shifted to park tried to restart. It wouldn’t. At that point I tried to put car into neutral I couldn’t. There is no way to shift this car into neutral. ( I checked with service department at gmdealer). This alone is dangerous the car cannot be moved. Anyway the car was towed to a dealer who fixed it. It was th fuel pump power module. The dealer and tow truck driver both told me this happens at least 5 times a week. There is no recall on this. My biggest concern is I could be on any road going high speeds and this part can fail. This is a death trap. There was no warning lights or messages to be found. PLEASE TAKE THIS MATTER SERIOUSLY SOMEONE IS GONNA DIE.

Purchased new in March 2023 -Repair Safety Restraint System failed (alert signal) failed late June 2023. Inspected at the Dealer/mechanic on July 11 2023, and it was determined the Safety Restraint System panel was defective. Part ordered late June early July 2023 (estimate). Part was backordered and not available for installation August 31 2023. Service department failed to notify me that the part was in. I had to call them. Appointment was set for Replacement part to be installed on September 6 2023. In the meantime a new alert appeared (Check engine light). I notified the service department of the new issue (check engine ) and the need for them to inspect that. The vehicle was due for an oil change and rotation as well. Service department determined that the engine failure resulting in the (check engine light) was due to a defective fuel pump/injection system. Part ordered and an appointment was set. Replacement part was installed on September 12 2023. Literally three days later, after the fuel pump/injection was replaced, another alert appeared (check engine light). September 15, 2023. This particular vehicle has major issues and I am contacting the dealer for a complete buy back and/or replacement vehicle. My safety and the safety of my passengers was at risk from the first minute the restraint system failure signaled. The part was backordered for a long while. I had no other form of transportation. The dealership did not offer a loaner vehicle or to pay for a rental car, nothing. In fact they did not seem concerned at all. Not concerned enough for the service department to place follow up phone calls to me with status updates over the many weeks I waited for the part to arrive. The car obviously has electrical and fuel injection issues straight from the manufacturing floor (which according to reports Buick is aware of). Ref. Edmunds and the federal safety agency reports. There are a host of reasons why my safety was at risk during the few mo of ownership.

Car shut off in middle of the highway. Couldn’t get it to start. Fortunately there was light traffic. Couldn’t get the car in neutral to push on side of road. Had it towed to a shop and it was a faulty fuel pump module. Manufacturer won’t honor warranty.

My vehicle's motor stopped without any warning in the middle lane of a busy freeway. I put the emergency flashers on but when I tried to restart the motor it overrode the flashers, causing a semi truck to just miss hitting me. The transmission went into Park mode and since this car is electronic shifting it would not let me put it in to neutral when the motor is not running . People stopped to help me push the car off the road but we could not get it into neutral. Very DANGEROUS situation to be stuck in a center lane on a busy freeway. ODOT and state police that stopped to help me said that they have never seen anything like this. Towed the car to a Buick-GNC dealer where they have had it for over 2 weeks now. They say that the fuel pump control module failed and they are on back order. My car has 11,200 miles on it.

The Buick died due to a fuel pump control module. This happened in a busy intersection. We were unable to force car into neutral so it could be pushed out of traffic . Ninth minutes later a tow truck showed up and had to drag car onto roll back. We have exhausted attempts with GM and its dealers and no answers. I also have a 2021 Gmc pickup with push button start and same problem. This is a major safety problem and a danger to driver and passenger .
