2022 Chevrolet Silverado fuel/propulsion system problems

“As I was driving, the vehicle threw a CEL and I saw the RPM’s fall. This happened multiple times, twice at an all-way stop sign, and once at a major intersection resulting in me being stranded with my vehicle in the middle of an active roadway, unable to move my vehicle. I brought my vehicle into the Chevrolet Dealership and the service department is claiming that I need to pay $1500 for a fuel pump with a CEL code that is not able to be duplicated. There is a TSB 24-NA-139 regarding my issue saying that it is not the fuel pump, it is the fuel pump control module. My issue is that the dealership wants me to pay $1500 for a fuel pump solely off of their “guess” of what the issue is. The bulletin calls out the P102B as one possible code related to the issues. I refused this service since this is just the dealership’s guess of what the issue may be and I believe the fuel pump control module should be replaced for free under the 8yr/80k federal emissions warranty. I requested that the dealership check the module as a part of the $245 diagnosis I paid for and they are insisting that the issue is with the fuel pump.”

“I was sent a notice of a recall regarding a fuel pump, power control module that needs to be taken care of, but it is not being accepted under my VIN number. I believe that there is this issue with my vehicle or something similar because every day I start the vehicle up for the first time and drive it. It is jerking me and does not have proper fuel or proper pressure to move the vehicle without jerking me. After 10 to 15 minutes it cleans up and drives better but then again we’ll redo it if I sit still for multiple hours and restart the vehicle again late in the afternoon it will do it all over.”

“Was driving at highway speeds when truck shuttered and rattled and quickly slowing down. Warning errors on dash stated "Reduced Acceleration, Drive with Care", "Service Emissions System", "Service Traction Control", "Service ESC". Got vehicle to dealer and they confirmed the error code (P0202 - covered under powertrain warranty), but then also noted an error code for P129F where the truck would not start up. They are recommending a replacement of the Fuel Pump Power Control Module. GM had updated a NHTSA bulletin (original: N262558690 - Emissions Recall - Fuel Pump Power Control Module - July 15, 2026) on August 12, 2026 that expanded the population of qualified models to include the 2022 GMC Sierra 1500. However, on September 1 they issued an updated notice that said "GM has since identified certain 2022-2023 model year Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles that were erroneously included in this recall and are not affected by the condition." I believe my truck was originally included in the recall, was removed two weeks ago, and now my dealer has subsequently diagnosed a Fuel Pump Power Control Module failure with DTC P129F and recommended…”

“I experienced a crankshaft bearing failure while driving my 6.2L V8 Chevrolet Silverado on the highway / freeway. Thankfully I was able to exit highway / freeway to avoid a car collision due to loss of power. My truck was towed to a certified Chevy dealer. This is a known issue for 2019-2026 6.2L V8 L87 engines. The truck was previously inspected by a certified Chevy dealer for prior L87 engine recall. It passed and they changed the oil type to 0w-40. Prior to this event, my truck was at the dealer for a low oil pressure issue / oil pan replacement. I picked it up from the dealer after the vehicle was repaired and drove it for about three days and then experienced the crankshaft bearing failure. No warning lamps illuminated prior to failure. My truck is currently at the dealer waiting for a new engine.”

“Engine abruptly lost power in middle of high speed lane. I did not have enough momentum to make it to safety, totally on the shoulder, Transmission locked up, couldn’t move vehicle to safety, Extremely dangerous situation!!!”

“2022 Silverado RST with the L87 engine loss propulsion in traffic of Memorial day weekend with approximately 43,800 miles on the vehicle. Has since been fixed by Chevrolet dealership. Also passed their Pico test, changed oil viscosity and oil cap still failed after their test.”
