SERVICE BRAKES, VEHICLE SPEED CONTROL, STEERING
Intermittent issue where info says brake failure/steering assist not working/limited speed to 43 mph. Very dangerous if you’re on the interstate. Becomes hard to steer, brakes don’t work, brakes start burning up. Have to carry tools with me to reset ecm. Very common problem with Silverado with 5.3 gas engine. Chevy needs to fix this issue before someone gets killed. I would give them my truck back if I could.

POWER TRAIN
This is a supplemental update to complaint #XXX filed February 7, 2026, regarding my 2020 Chevrolet Silverado 3500HD Diesel (VIN: [XXX] ). The vehicle experienced a sudden and complete loss of propulsion on January 21, 2026, consistent with the defect mechanism described in Recall 24V797. Recall software was installed May 27, 2025. Failure occurred eight months later with no warning. GM's response has been as follows: A Field Technical Service Engineer made a remote determination that the failure did not match the recall without physically inspecting the transmission. GM Executive Resolution required teardown at customer expense with no reimbursement guarantee. The authorized dealership (Dave Kirk Chevrolet, Crossville TN) declined to perform a documented inspection -- citing unwillingness, not inability. Written refusal was withheld for over one week. GM's Executive Resolution liaison admitted she had known of the refusal and withheld that information from me, directly delaying my ability to act. The final repair order (RO 50479) contains a self-documented notation: "Added tech notes 3/16/26" -- eight weeks after the January inspection. The transmission pan was fully removed, fluid was discarded, and pan bolts were not reinstalled. The only photograph provided does not reflect as-found conditions. Evidence integrity has been materially compromised. The vehicle has been without propulsion since January 21, 2026. Full chronology, documentation, and supporting evidence are attached.

ENGINE
I have 2020 Chevy 1500 with L87 engines on it. We have the exact same issues that the 2021 1500 recall is having. Loses power, noisy engine when at start. Paradise Chevrolet in Temecula told me that they were going to replace the engine per GM but then GM only auth the repair. 8 barring kits, 8 rings 8 piston kits lot of bolts and gastkit and seals. Talked to GM every tho it’s the same engine they won’t replace it since not on recall. Don’t understand how the same engine in a car one year before the recall. I have all the paperwork video of the noise pictures of the Pistons. I failed from the dealer. Had to get the truck towed to the dealer cause the car wouldn’t turn on and all this happened with only 68,833 miles.
