What owners say
As I accelerated after the traffic light turned green the vehicle stalled. I was able to move the vehicle to the curb on XXX [XXX] is a two-way road. The vehicle stalled while on an active road which could have led to my vehicle being rear ended causing potential injuries to myself and other drivers. The engine turned over and there was fuel in the gas tank, however, the vehicle wouldn't start. A warning light showed: "low battery", but since the engine was trying to start, it seems unlikely that the battery was low. A second warning light showed: "battery saving" mode. These lights appeared once the vehicle was parked on the curb of the road. The vehicle was towed to David Chevrolet, a GM dealership on [XXX] about 2 miles away.

Car will not crank, stalled while cranked, throws code P023F
XXX the car had gas, turned over, but would not start. I had it towed to a repair center who towed, did diagnostics and came up with the codes for a bad fuel pump control module. It was replaced and the car starts. There was no warning. Problem was confirmed by an independent service center. All documentation is available.

My car will be running fine but the lights on the AC panel wont work. My car will stop and shut down while driving. Ive taken it in for service and they told me my battery cabels were lose. The second time it happened I got a notification of low battery level and it shut off and will not start. I just replace the battery 2 years ago. The service department tested my battery and said it was fine
On February 4, 2026, my wife drove to the bank, a trip of about 10 to 15 minutes, and turned off the car at the ATM. When she tried to leave, the vehicle wouldn't start. After a while, she opened and closed the door and locked and unlocked the car twice with the remote control, and the vehicle started and she was able to drive, but all the warning lights on the dashboard remained on. It is currently at a Chevrolet dealership for diagnosis.
Car was running fine yesterday, today does not want to start. Thought it was the battery, bought anew battery. Still wouldn't start. Rest of cat is getting great power. Code reader is reading its a fuel pump control moduler which just so happens to be in an open recall for my exact year of vehicle yet my vin number does not pop up on the GMC website under active recall. I have a 2021 chevy blazer .
On [XXX], I was driving my Blazer up to our local Museum to grab some information. The Museum is about a mile and a half from my house. When I had left my house, the car was driving like normal. I pulled into a parking spot at the Museum, and I went to shut the vehicle off, and I thought maybe the check engine light had come on but wasn't completely paying attention to the dash. About 10 minutes later I went to restart the vehicle to leave and I noticed the check engine light on. Since the vehicle seemed to be driving okay I thought I could make it home and check the car's computer to see what the issue was. As I was leaving the parking lot I stopped at the end of the parking lot to look before pulling out onto the road and the Blazer said shift to neutral and restart the vehicle. When I did that the vehicle would not start. It would just crank and crank and then it would finally start for a few seconds. I was going to back my vehicle up out of the road but each time I would try the car would die. I am very thankful this did not happen on the highway or even on the freeway. A friend and myself had to push my vehicle back into a parking spot. The DTC code is a P023F. When this happens, you can't technically shift the vehicle into neutral to push it out of the way because the car has to be running to shift. I was able to force it into neutral, however. I made an appointment with Awesome Chevrolet in Chehalis WA and had to have it towed to the dealer. They stated it was the fuel pump module. I had at that time 18,388 miles on the odometer. Unfortunately, I no longer feel safe with this vehicle in case it happens again. Where I am hours from home or on a 2-lane road or freeway. The fuel pump module failure appears to be a known issue with GM vehicles. The fuel pump module was replaced and was able to be replaced under warranty. I hope that it does not happen again.

To whom it may concern; my son's fiancé was driving on the highway and the vehicle had a sudden loss of power. Afterward, it turned off and would not re-start. After towing the vehicle to a repair facility (out of warranty by mileage, 45K) were advised they retrieved DTC P023F and advised the fuel pump control module failed. I did some checking and found that GM is aware of the issue and has released T.S.B. #PIP5964C, which states "CRANK NO START, STALLING, LOSS OF POWER, FUEL GAUGE INOPERATIVE/ERRATIC, MALFUNCTION INDICATOR LAMP (MIL) ILLUMINATED P023F P129F". Fortunately nothing happened, she is young and smart and was able to handle the situation without incident. However, I shutter to think if my father in-law would have been driving, and/or any individual who would have panicked.
The curtain airbags deployed at slow speed going over a speed bump. It shut off and would not start again. ONSTAR said it had been in an accident but it had not. The vehicle is at the dealership waiting on General Motors to do an inspection. There were no warnings or messages until it shut off.
