2022 GMC Sierra 1500: hesitation when accelerating

Filed Sep 10, 2026 · Engine · WA

I purchased said vehicle with a little over 76,000 miles on XXX from NW Chevrolet, [XXX]. Dealership service the engine on XXX and remained on their lot until it was sold. While driving home, I smelled gas fumes coming into the cabin and the engine was misfiring causing slight hesitation in motor acceleration while adjusting to speed limits and climbing hills. I told management at the dealership about these issues on XXX. My vehicle is currently in the shop to fix the fuel injection system, spark plugs, grounding issues as of XXX to fix the dealerships mistake costing more out of pocket expense. Management will not do anything about it because it was sold (As Is) without a warranty which I refused to purchase through finance and interest charges on a car loan. I purchased a 4-year warranty through Endurance on XXX with a 30 day wait period before filing a claim. GM is letting their dealerships advertise and sell problem vehicles with known motor issues to consumers while marking up the sale price. Vehicles should never be sold until GM fixes all motor defects before advertising to the consumer. The consumer is at serious financial risk when getting an auto loan paying on a broken vehicle.

My 2022 GMC Sierra started hesitating two weeks ago between the speeds of 17-35 mph. It also hesitates going downhill. When I try to accelerate it hesitates causing a serious safety issue for me driving. I cant trust to move when I need to move across a busy intersection with semi tractor trailers coming at me. I can trust it to tow or haul anything anymore. This is well known and documented problem General Motors has and the company deems it "Normal Operations" which is totally not normal.

The vehicle is subject to Safety Recall N252494001 (the federal safety agency Campaign 25V‑274) due to manufacturing defects in the engine crankshaft and connecting rod bearings. • Component/System Failed: The 6.2L V8 (L87) engine crankshaft and connecting rod assembly. The engine is available for inspection upon request. • Safety Risk: The defect can cause catastrophic engine damage and sudden loss of propulsion while driving, significantly increasing the risk of a crash. • Dealer/Manufacturer Confirmation: The problem was confirmed via the issuance of Safety Recall N252494001. A dealership inspection was performed previously as part of the recall. • Warning Signs/Symptoms: Common symptoms include engine knocking, check engine lights, and hesitation before sudden failure. The Issue with the Remedy: Federal law (49 U.S.C. § 30120) requires manufacturers to remedy safety defects "without charge". As a permanent safety remedy for this defect, GM has mandated a switch from 0W-20 to 0W-40 (dexosR) oil for the life of the engine to prevent bearing failure. However, the dealership and manufacturer are refusing to provide this mandated safety spec change without an ongoing $85 surcharge per oil change. While they performed the initial "inspection" oil change for free, they are now using the recall-mandated spec change to create a financial burden on the consumer. Because 0W-40 is now the mandatory factory requirement to prevent the safety defect, charging a premium for it constitutes a failure to provide the recall remedy "without charge." General Motors refuses to offset this cost, effectively penalizing the owner for a manufacturer safety defect. The dealership is also failing to honor my Platinum Wrap warranty and GM Prepaid service contract to perform the continued oil changes without additional charges.
