2021 Chevrolet Blazer

The vehicle has 14,000 miles on it and the fuel pump control module has gone out on it. This happened while away from home and could’ve caused a serious situation if this had happened in a remote area where customer could’ve been stranded or if customer were pulling onto a busy road. Luckily it happened in the parking lot of a store. The vehicle was running fine on the way to the store. When customer came back out to the vehicle it cranked up but then stalled which also left customer in between parking rows, potentially causing an accident. I have the old fuel pump control module readily available for inspection. Customer had an updated version that replaced the original one that was in it. There were no signs or indications that this was going to happen until it did. I know there was a big issue / recall with the modules on Silverado and Tahoe’s etc. around the same manufacturing era. For reference- 1/2 tank of fuel, no CEL until after it happened, approx. 88° outside, coolant temp near 120°, vehicle battery had good voltage and battery cells are good

Fuel pump module. Driving highway speeds lost all engine power as car sputtered to a stop. Luckily car srill ran enough to maintain power steering and brake function. No warning lights.Thought it was bad fuel as I had filled the tank the prior evening with little driving after that. Towed to dealership after spending 2 hours in 100 degree plus weather on the side of the highway. Dealership states it is the fuel pump module. Dealership is waiting on new unit to be installed.

The Transmission valve control body went out while I was on the freeway.I was able to pull off to the side safely but has rendered my vehicle inoperable until I get this repaired. I have confirmed this with the dealership. This is a large enough issue with vehicles that the necessary parts are on back order. Anecdotally, the dealership told me there was a vehicle that was waiting for almost 3 months for a replacement part. For context I have regularly maintained this vehicle and just 10000 miles ago got my transmission flushed.

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.

On Friday, April 28, 2023, at about 11:30 am, my car, died as I was driving it out of the grocery store parking lot; luckily, it didn’t happen as I was crossing the busy highway. I attempted several times to restart it, with no luck. There were no warning lamps, messages or other symptoms of this problem. The vehicle was in the middle of an aisle, blocking the aisle and many cars in parking spots, so I managed to get it into neutral and it backed around into parking spaces where the left rear quarter stopped against the front tire of a Ford F-350. I was actually thankful for the truck as I had no steering or brakes, and I was on a slight hill heading towards the road. I had it towed to the dealership, which was unable to tell me what the problem was before I obtained a ride home at 3:30 pm and that they would call me when they had it figured out. When I returned home, my husband had searched the internet for recalls for the car and was unable to locate any. I called the service department the next day, Saturday April 29, and was told that the problem was the fuel pump control module, which was under warranty, and it could be 3 months before it was fixed as they didn’t have one, and there was a large backorder. The fuel pump module was recalled on other GM vehicles GM #N212382040 and NHTSA campaign #21V739000, and there was another recall by GM on February 6, 2023 Recall #N222372310 that did NOT include the Chevy Blazer.
