2022 Chevrolet Tahoe Fuel System Problems

The vehicles ability to accelerate was limited. Several system service warnings came on along with the check engine light.

During a normal acceleration from an on-Ramp onto a major interstate a Check Engine Light (CEL) came on with warnings of safety features no longer being active. The vehicle begin vibrating abnormally and the pedal was not very responsive. I took the next exit and stopped at an auto parts store to have the engine code checked. Cylinder #2 misfired due to an injector issue. The vehicle was confirmed to have this issue at a Chevrolet dealership. The car was a CPO through FORD and was covered. I owned the vehicle for 14 days. This unit has the L87 Motor, and had already undergone a motor replacement under the recall warranty. The injectors apparently were not replaced, only the O-Ring. Unlike many manufacturers GM has removed Fuel Injectors from their PowerTrain warranty. A motor with under 5,000 miles was not covered since the body and bolt-ons were original with 45,000 miles. GM has a very recent history of injector recalls and issues. These injectors should undergo the same scrutiny as previous GM injectors.

The fuel filler neck for the diesel has a plastic neck extension made of cheap plastic and it broke making it a hazard to even fill the vehicle up and diesel fuel is spilled, not secured, and fumes could cause a fire hazard because the piece is faulty. GM customer service ignores me and transfers me over and over until they hang up and never actually talk to me about this

On 6/26/2025, I was on an elevated one lane exit ramp of a major freeway. My 2022 Tahoe suddenly lost complete power with no warning at all. The car behind me slammed on his brakes and narrowly missed me as I could do nothing except get as close to the concrete barrier as possible. Thankfully the Tahoe went into Neutral so I managed to roll down the ramp. I prayed that I could get across 3 lanes of the frontage road without getting hit so I could safely make it into a parking lot. I had to call a wrecker even though I was literally two driveways down from a Chevrolet dealership. I could not make it that far with no power and using only the momentum from the exit ramp to get me to safety. I have 32,635 miles on the Tahoe. It was a faulty fuel pump power control module.

Engine stalled while driving and vehicle would not restart. Pulled over and was stranded on side of the road. Had vehicle towed to dealer. Was diagnosed as failed fuel pump control module.

Driving vehicle from work to home when the vehicle started to stutter and immediately shut down with no power or any capability to turn the vehicle off of the road. This shutdown immediately caused blockage of a major road; since the vehicle could not be moved due to no power to steering wheel nor ability to place the vehicle into neutral. Determination was that the fuel module went bad. No warning of failure of component was indicated by check engine light until after the incident happened. Luckily this shut down of all components of the vehicle did not occur on a high speed road since I did not have any control of the vehicle after the fuel module failed.

Vehicle was driven into parking lot and was idling. Without warning, it began misfiring and stalled. Vehicle would not restart and was towed to the nearest dealer. The diagnosis was a fuel pump driver module that had internally shorted. Thankfully, it failed in the parking lot. We had recently arrived at this location for the winter having driven the vehicle approximately 1500 miles over 4 days. We were lucky the failure did not occur on the highway as the unexpected stalling would potentially be a significant safety concern. Please note that this vehicle is a 2022 Chevrolet Tahoe. The 2021 Tahoe was under a recall for this same issue (see recall N212332040). The dealer said that this is a common problem with these vehicles. Perhaps the recall needs to be expanded.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that several days after purchasing the vehicle she was informed by an individual that there was something hanging down from underneath the vehicle. The contact inspected underneath the vehicle and saw that the fuel tank strap hanger was not installed properly and was hanging down underneath the vehicle. The contact had the vehicle towed to a local dealer who confirmed that the front fuel tank strap was not properly installed. The mechanic installed new fuel tank straps and the vehicle was repaired. The contact was awaiting a full inspection before going to retrieve the vehicle. The manufacturer was made aware of the failure. The failure mileage was approximately 353.
