1)The truck experiences an intermittent but complete failure of the Crankshaft Position (CKP) Sensor circuit and multiple chaffing points of the vehicle wiring harness. This issue is a documented manufacturing and electrical defect covered under General Motors Technical Service Bulletin (TSB) #24-NA-012. Yes, the truck is available for inspection. 2)This issue has happened to me on five occasions where I was traveling over 50 MPH and the vehicle violently jerked with my wife and children in the truck with me. This defect poses an immediate, severe safety hazard due to unpredictable, sudden engine/transmission jerk while operating at highway speeds. My main priority is my family! This failure compromises my ability to safely maneuver, accelerate, or steer the heavy-duty vehicle out of active lanes of traffic, dramatically increasing the risk of a high-speed rear-end collision or crash. 3) The problem has been reproduced by Rick Hendrick Chevrolet Norfolk and R.K. Chevrolet Virginia Beach. There are service invoices confirming these reproducible jerks and subsequent engine codes thrown. 4) No, I brought this up to General Motors as a safety issue but they have brushed off my concerns. 5) The second time I had the violent jerk I had a message appear on my DTC that stated "174 mi Until 65 MPH Max Speed and Service Emission System See Owner's Manual" that was on 2/21/2026. Extra Note: The vehicle sat disabled at a dealership service center for 21 cumulative days during the initial attempt to repair this specific defect under TSB #24-NA-012. Merely 58 days after the repair, the identical crankshaft position sensor circuit/wiring failure reoccurred while driving, resulting in secondary engine failure and requiring a visit to an independent service facility for diagnostic verification and wiring replacement. Internal vehicle history confirms that prior to my truck ownership the crankshaft position sensor was replaced in December 2025 weeks before I purchased the truck.

My company purchased a new 2022 Chevrolet Silverado RST from Bomnin Chevrolet Manassas in December 2022. The vehicle has been properly maintained according to GM’s recommended maintenance schedule, including routine oil changes and tire rotations. On February 10, 2025, the truck began shaking and repeatedly shutting off. Bomnin Chevrolet diagnosed a failed fuel injector and completed the repair. No loaner vehicle was available, requiring me to use Uber transportation until the vehicle was returned on February 12, 2025. On May 19, 2025, the truck again shut off multiple times while traveling approximately 45 mph. The vehicle was returned to Bomnin Chevrolet, where it remained for three days. No loaner vehicle was available, forcing me to rent a vehicle from Enterprise. The dealership ultimately stated it could not diagnose the problem and advised that the failure would have to occur again before it could be repaired. The vehicle was returned on May 22, 2025. On June 18, 2026, the engine shut off while driving and would not restart. The vehicle was towed to Bomnin Chevrolet. After several days, the dealership advised that the engine had suffered catastrophic failure due to a lifter issue and required complete replacement. GM approved the warranty repair; however, the replacement engine is on national backorder. No loaner truck was available. The dealership offered only a $44-per-day rental reimbursement, which is not comparable to the business use of a full-size pickup truck. As of June 29, 2026, the vehicle remains at the dealership, leaving my business without a suitable replacement vehicle and significantly impacting daily operations. I am requesting a voluntary manufacturer repurchase of the vehicle, reimbursement of all rental cars, and a fare financial compensation package for any inconvenience.

Took my 22 silverado with the L87 engine in for the recall. The dealer stated that my vehicle had a tick in the motor but it passed the pico test. They switched it to the 0W40 oil and stated that my engine will probably blow here soon, but until that happens there hands are tied. Today i took my truck in for another inspection because my motor had a very loud Tick noise almost sounding like metal on metal, they stated they did not hear anything and without more proof nothing can be done. My safety is very much put at risk when i report something to them thats happening with the vehicle, and if my motor blows while im driving 80 MPH i could crash into others or even die myself. My transmission is also having problems of what i would call Bucking when you put it into drive, i also filled up with gas last week shut my truck off pumped gas, got back into my truck and started it, went to put it into drive had no power shut it off and did it again, i had power but my rear wheels were locked up and wouldnt budge. shut it off turned my truck on and engaged the 4 wheel drive, and then disengaged it, still not able to drive. shut it off and put it back into drive and the rear wheels were able to drive normally. Dealership says theres a recall on the transmission to add a spacer plate so it was ordered. This issue needs to be taken very seriously this is why they say theres only 3% motors affected is because they decline the motors that have actual problems but its still running so to them its fine.

2022 Silverado 1500 LTZ w/6.2L 38082 total miles. First engine replacement due to seizure at approx. 17,782 miles around June/2025, The vehicle lost all propulsion and stopped running while sitting at a stop sign at a four way intersection during a really bad thunderstorm, Luckily the intersection was on a declining hill and i was able to coast it into nearby parking lot .I'm a senior citizen with a replaced hip and couldn't have gotten it out the roadway otherwise. Contacted Gm through the App. to arrange service and tow. The tow couldn't be completed by the assigned wrecker service because it was busy with other tows because of the severe storms. The following afternoon, it was towed to the local dealership for service. It took approx. a week before i was finally informed that the engine seized with explanation.. Repair took just over 3 months to complete under warranty/recall at dealership, didn't get vehicle back until the beginning of September 2025. Engine replacement Inspection passed by GMC on the recall inspection at local dealership. Oil changed from factory 0W-20 to 0W-40 around January or February 2026 if I'm not mistaken. Driving down the highway on 06/03/2026 and all the sudden loss of propulsion. Zero warning! Lucky I was able to coast onto an exit ramp without getting in an accident with hwy. traffic! Luckily i was able to find a church parking lot and asked a person that i knew to give me a ride home. Because it was after business hours, i waited till the local dealership opened the next morning and spoke with service personnel and they arranged a tow to take it to the dealership. As of the end of the business day 06/05/26 I have no word from dealership on the status of vehicle, but the vehicle experienced the same symptoms, a sudden total loss of power and no start, just a single click and no electrics. I feel that the inspection testing and oil change does not address and/or fix the root cause of these engine failures
