ENGINE
The water pump went bad at 31,000 miles. If I continued driving and the pulley fell off the engine would overheat. I took it to the dealer and they confirmed the pump failure and want me to pay over $1,400 for repair that should be covered under warranty. There was no warning lamps lit, the pump just started making a grinding sound.

UNKNOWN OR OTHER, ENGINE
My truck started skipping and over time the check engine light came on. I took it in and they are saying it is the lifters, which is costly. I know this truck was built during COVID and I know a lot of the manufacturers were dealing with skeleton crews. I heard this was an issue with the 2021 Silverado trucks, and a recall. Can you please advise?

2021 silverado engine failure. Yes it was inspected by a dealership and my extended warranty company and serviced by the dealership. Back on August 5th I experienced a misfire cylinder 3 and felt loss of power. On August 7th the dealership diagnosed both camshafts, 1 lifter, 1 valve, and 1 fuel injector was damaged and never received at warning lights or messages on the dashboard. I was without the vehicle for 39 days and within 10 hrs after picking up the truck i got an engine light on and several new codes on it and can not be driven and being towed. I feel these engines need a recall as it is well documented that these engines go between 60 and 80,000 miles and some a lot less than that, mine has 70,800 and went and now being towed with in less than 24 hrs after engine repair. I will be in contact with a lawyer to follow up on this matter.

ENGINE, STRUCTURE:BODY
Statement for NHTSA Subject: Safety Complaint – 2021 Chevrolet Silverado Unexpected Jerking/Harsh Transmission Engagement I am submitting this complaint regarding my 2021 Chevrolet Silverado 1500 2.7L Turbo with approximately 128,000 miles. My vehicle has developed a recurring problem involving harsh/jerking transmission engagement, hesitation, shuddering and abnormal shifting. The truck can jerk when engaging or changing gears and has also experienced a hard engagement when shifting from Reverse into Drive. During normal driving, the vehicle can hesitate or feel as though it is repeatedly fluttering/shifting instead of providing smooth and predictable acceleration. The vehicle has produced diagnostic trouble codes including P0700, U0100 and P0420. I am concerned that this condition could create a safety hazard, particularly if the vehicle unexpectedly jerks, hesitates or fails to respond normally when accelerating or changing gears in traffic. I am requesting that NHTSA document this complaint and review whether there is a pattern or potential safety-related defect involving transmission engagement, shifting or drivetrain control on 2021 Chevrolet Silverado vehicles. GM has published service information concerning delayed and harsh transmission engagement on certain Silverado applications, including 2019–2021 models, which makes me concerned that my vehicle may be experiencing a related issue. I am retaining my repair records, diagnostic information, receipts, videos and mileage/date information documenting when the problem occurs. I am willing to provide this information if requested. Please help me get my truck corrected, I love my Chevy Truck. Thanks Sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
My 2021 Chevrolet Silverado 1500 RST with the 6.2L engine experienced an engine seizure. The engine was replaced by a Chevrolet dealership under a GM safety recall. Immediately after picking up the vehicle following the recall engine replacement, the truck stalled while still in the Chevrolet dealership parking lot. There was no warning before this first stall. We continued our trip because we did not realize at the time that the stall could indicate a problem following the engine replacement. During the drive from [XXX] to [XXX], the problem continued. In [XXX], the check engine light illuminated and the truck began malfunctioning. The vehicle subsequently stalled again. The problem continued after returning to [XXX]. A Chevrolet dealership in [XXX] inspected the vehicle and reproduced/confirmed a problem involving the camshaft position sensor wiring/connector. The dealership demonstrated the problem by manipulating the connector/wiring and recorded a video of the diagnostic procedure. The vehicle is currently at the Chevrolet dealership and is available for inspection. The affected component should also be available for inspection because it has not yet been repaired. The [XXX] dealership has characterized the wiring/connector condition as normal wear. However, the first stall occurred immediately after the GM recall engine replacement, while the vehicle was still on the repairing Chevrolet dealership's property. Unexpected engine stalling creates a serious safety risk because the vehicle can lose propulsion without warning while driving, including at highway speeds or in traffic. I am concerned that the camshaft position circuit/wiring/connector problem may be associated with the recall engine replacement procedure or replacement engine. I am requesting that NHTSA investigate whether other vehicles receiving this GM 6.2L engine recall remedy have experienced similar camshaft position circuit failures or unexpected stalling after engine repair.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The automatic power-unlatching tailgate assembly failed. The tailgate unlatches, opens, and cycles closed completely on its own while the vehicle is in motion and driving on public roads and when the gear shifts from drive to park and park to drive. The vehicle and the tailgate assembly are fully available for inspection upon request. The tailgate opening unpredictably while driving at road speeds creates an extreme safety hazard. It risks cargo flying out into traffic, which could cause a severe multi-vehicle accident or injure pedestrians. Additionally, it creates a massive driver distraction while trying to monitor the opening and closing tailgate in the rearview mirror while maintaining control of the vehicle. Sometimes there isn’t a warning light and sometimes it shows a warning light “tailgate open” I have taken it to the dealership and was told it isn’t part of the active recall for similar makes and models and my vehicles year/make/model needs to be added to the current recall for these concerns. It opened on its own while in park and turned off when the mechanic was replacing the license plate light.

POWER TRAIN
While driving on the road, the transmission in my truck completly neutralized all the gears (meaning it just started revving and slowing down rapidly in the middle of the road with cars in front of and behind me). And almost got me hit by several cars. I got the vehicle towed to the Chevy dealership it was bought from. The mechanics then confirmed the code was for a failed valve body in the trucks transmission. Which they had recalled in all the diesels but not gas engines.

Vehicle went into reduced power mode and was taken to the dealership. They had to tear down the motor to diagnose the problem and determined it was the crankshaft and the motor needed to be replaced. It was out of factory warranty however it has an extended warranty and the warranty covered 80% of the repair. We still had to pay over $3k out of pocket. Vehicle is now making engine noises again and will be getting taken back to the dealership to be looked at. Currently not part of the recall however truck was built at the Mexico plant in question. We believe it may have the faulty components as well.

Rear tailgate does not open and sometimes will show a warning on the dash that the tailgate is open when it is not. The tailgate for the heavy duty 2500/3500 trucks were recalled for the same reason but not the 1500 trucks. This is a common issue on the truck forums and is an unsafe condition.
