Engine And Engine Cooling Problems of Chevrolet Silverado 1500 - part 2

I purchase a brand new 2026 silverado zr2 with a 6. 2 engine. A little over a week later at 511 miles it left me stranded on the side of the road. Towed it to the dealership and the dealership advised there was a misfire and cylinder number eight. However, they were unable to find a solution and had to contact gm engineers. I had to replace it with another new vehicle and lost money on the “trade”. Dealership only advised that “it needed extensive repairs”. It’s clear that the 6. 2 issue had not been addressed properly.

Leaking oil cooler lines that had a customer satisfaction campaign but it’s over and now they are leaking.

I am filing a complaint regarding a potential recurring safety defect related to recall NHTSA 25v274 (gm n252494001). On July 29, 2025, my vehicle stalled while driving on the highway and was towed to quality Chevrolet. The dealer diagnosed a failed starter and battery fuse link. During this visit, I authorized inspection for recall 25v274, concerning possible crankshaft or connecting rod failure. I was told my vehicle was not affected but the dealer performed the recall remedy by changing the oil to 0w-40. On October 5, 2025, the vehicle developed a loud knocking noise from the engine. Quality Chevrolet diagnosed a connecting rod failure, the same issue identified in the recall. On October 10, 2025, I was advised that gm approved a full engine replacement due to internal damage. However, I was also told the new engine will use lower viscosity 0w-20 oil, contradicting the prior remedy intended to prevent this failure. This suggests the original recall fix was only a temporary measure, and the defect remains unresolved. I request that NHTSA investigate whether the current recall remedy adequately corrects this safety issue and whether gm’s use of 0w-20 oil could allow repeat failures. Additionally, I request assistance or reimbursement for vehicle payments, as my vehicle has been undrivable for an extended period due to a manufacturer defect. Thank you for your time and attention. I can provide all service records and diagnostic reports upon request.

I have had a problem with the theft deterrent system which, shuts the truck down and issues a message saying "turn the driver side window down and then up". After 5 minutes the truck starts back up by itself? this has occurred sitting in popeyes drive thru line in August 2024 in benton harbor, mi. This has occurred 3 times in the past week, 09/25/25 driving on garrett road it shut down during the entry into a "s curve" 09/26/25 driving into my drive way 09/28/25 driving into my drive way took the truck into wimberley chevy dealer and they searched for error codes and checked some of the ground wires not connected properly and found the negative cable on battery was ok. I don't know if any other wire connectors were checked, however I have had this before and the dealer said they would have to keep the truck as it may take quite some time in confirming all connections were good. The service manage of levalley cheverolet stated that they would require a $1,000 deposit for them to start looking into the problem and again require another $1,000 deposit to continue and then another etc. I will not drive my truck on any major highway or in any very busy large city for fear of having a return of another shutdown and no place to pull into as I was only coasting when I entered the "s curves" and had space.

2021 chevy silverado engine was under the 6. 2 recall on sept 4 2025. The engine blew and the truck was taken to local Chevrolet dealer. It had 38k miles on it. It stillf ell under the original powertrain warranty and the recall. Dealer informed me new engine was needed and ordered.

I am filing a formal complaint regarding a serious safety concern with my 2021 Chevrolet silverado, following the completion of recall n252494001 performed by galleria Chevrolet in dallas, TX. Prior to this recall work and related inspections, my vehicle operated without any abnormal engine noise. After the recall inspection and a subsequent fuel injector repair performed by the dealer, my vehicle began producing a bottom-end engine noise that had never been present before, and ultimately we have catastrophic engine failure. What is highly concerning is that the dealership staff previously documented the situation in writing as follows: “we performed the recall inspection and the truck passed. After performing an injector repair now there is a bottom-end noise when it's running. Did the failed injector possibly affect the validity of the test? that may be the case. We know that the truck did not experience the noise before the inspection; is it possible that the steps we took affected the truck in a way that got the noise to show itself? that’s what we need to determine. ” despite this acknowledgment, the dealership is now denying any responsibility, classifying the damage as unrelated “wear and tear”. This reversal appears highly suspicious, as it contradicts their own observations and written notes. It suggests that the dealership and gm may be refusing to fulfill their obligations under the recall and repair warranty, leaving me with a vehicle that has a blown engine and a significant safety risk. Given the timing of the noise, occurring directly after recall work and injector repair, and the internal documentation from the dealership itself, I request NHTSA investigate whether: this issue is part of a broader trend affecting other vehicles under the same recall. Gm and its dealers are properly honoring their obligations to fully repair vehicles impacted by recalls. Consequential damage resulting from recall work is being systematically denied coverage.
