Driving down the road and the vehicle shut off and said to restart. Wouldn't start back up. Check and found a 400 amp fuse was blown. Tested starter and was fine. Restarted the vehicle and it made a loud rattling noise and shut back off. Sent it to the dealer and they found that number 1 and 2 rods overheated and locked up the motor.

My 2021 Silverado with only 80,655 miles had to have the engine replaced. On 11/20/24, my vehicle indicated a P0303 code for miss-fire in cylinder 3. I took my vehicle to for repair to a local Chevy Dealership and was informed of the following: 1) Needed programming changes to the fuel injection based on service bulletin N242450631. This repair was completed by the dealer. 2) Needed a “tear down” for further diagnostic. It was determined that the specific code could not be repaired and the entire engine needed to be replaced which was done at my cost. The details on service bulletin N242450631 are limited and do not describe issues that could be caused by the fuel injector problem. Relative to service bulletin N242450631 fuel injector issue, based on my experience with my vehicle, I believe this fuel injector programming bulletin issue caused the engine malfunction and subsequent need to replacement. Before the bulletin repair was completed, I know that my vehicle engine surged often. Looking back now, this constant surging had to be hard on the engine and likely caused the failure. Regardless, if it wasn’t the service bulletin that caused the issue, a vehicle engine should last more than 80,000 miles. I believe GM needs to take responsibility for the engine failure which I believe was caused by faulty workmanship, design, computer engine programming, or some combination of these issues.

POWER TRAIN, ENGINE
Lifter failure at 8629 miles. All warning lights went on at time of incident, truck would barely drive home and I had it towed into the dealership where they replaced the entire bank of lifters. This is on my repair order- "Checked and found dead mis on cylinder 4 and ticking noise from engine//performed compression test and found no compression on cylinder 4//removed passenger side cylinder head and found lifter bad causing push rod to bend//replaced all lifters on right bank and 1 pushrod//changed oil and filter//filled coolant and test drove and found all ok. I called Chevy at time of incident (1/21/22) and opened case# 9-7252876703 stating I wanted both banks of lifters replaced because I pull a 30' camper with my family and didn't want the other side to fail while I'm pulling 7000+ pounds. They declined to replace the other bank stating that since the vehicle had more than 5000 miles it did not qualify for both sides to be replaced and it was for only vehicles after 11/21 and mine was built 2/21. I still would like to get the other bank of lifters replaced under warranty.

UNKNOWN OR OTHER
Originally Chevrolet offered a 2 phase approach for this recall. First phase was to install monitoring software in the ECU and TCU to monitor for early transmission control valve premature wear. Second phase was to actually replace the suspect valve. I've just received a second correspondence from Chevrolet for this recall, now only offering Phase 1, TCU and ECU monitoring software installation. So if the monitoring software detects premature valve failure, the vehicle will be limited to 5th gear. I don't think limiting a vehicle to 5 our of 10 gears is a safe solution. If I'm on the freeway, towing 10,000 lbs, and my vehicle is limited to 5th gear, I may have to travel a very long time at way below posted speed limits before I can get to a dealer for repair. As we all know, travelling on the freeway at lower than posted speed limits can be just as dangerous as travelling above posted speed limits. And in fact, here in Idaho, if you're travelling below posted speed limits you can be fined just as if you were exceeding speed limits. I feel Chevrolet's original solution is the best. Replace the suspect valve proactively instead of actually waiting for it to fail which can possibly cause an unsafe condition.

2021 Chevy Silverado RST 6.2 Crankshaft Failure – Trust bearing / Main Bearing – Verified by GM dealership. This incident occurred without any prior warning indicators. The check engine light illuminated only after the engine began to seize, and the engine abruptly stalled. At the time of the failure, the vehicle was traveling at 60 MPH on a busy highway. Upon the event, the vehicle came to an immediate stop and could not be restarted. The engine failed to turn over, rendering the vehicle inoperable and partially obstructing traffic. The vehicle was subsequently towed to a local General Motors dealership, where it was determined that the failure was due to a crankshaft thrust and main bearing issue. The vehicle has 27,000 miles on the odometer.

I have just been made aware that there is a lot going on right now with the l87 6.2 motor. I purchased my truck last September so I e had it almost a year 1/2. I recently started having what seems like a misfire issue as of 1/20/2025. I have it scheduled to be checked out Friday 1/24/2025. I’m just reporting this to cover my back if any recall or anything comes about. In addition I’ve had regular oil changes and maintenance on the truck. It’s currently inspected and insured.

Started my truck and the check engine light was flashing along with a few other warming lamp lit up. When I went to drive the truck the engine started to make some noise, and didn't have much power. After being diagnosed by the dealer ship the motor needed new valves, lifters and camshaft. The bill for the repairs is going to be around $8,500 and GM is not willing to help with the costs.

The crankshaft bearings failed causing engine to knock very loudly. I didn't get an engine light. Dealership did replace one bearing and said lifters we fault and replaced. This happened with just over 33000 miles on truck. I didn't receive any extended warranty from manufacturers for any problems that may occur in future from pieces of metal or other contamination to inside of engine.
