POWER TRAIN
10 speed transmission failed at 70K miles. Metal found in the torque converter. Manufacturer recommended routine maintenance was performed on transmission. There needs to be a recall on 2020 to 2021 vehicles with the 10 speed transmission due to the reporting of safety issues of the vehicles locking up while driving. I was lucky to feel the issue happening and getting off the road before it was able to lock up on me causing serious injuries. This needs to be addressed and taken seriously before someone loses their life. Best regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have 112,000 miles on my truck and my 6.2l motor is going out or knocking. I am very unhappy that my truck is not covered under the recall and I would like to understand why it is not since this is the issue of the recall. I would like to clarification on this and what options I have since it is going to cost me 14k to replace the motor. Case #101943027

ENGINE
I bought a 2021 Chevy Silverado 1500 Badlander edition in February of 2025. I love the truck and drive it everywhere. I have brought it in for every oil change when needed. I got my first oil change April of 2025 and had no issues. Then I got my second oil change June of 2025 and both of these were done at the dealership that I purchased the truck from. At the June oil change I asked Jeff Belzers to do an oil consumption test and they said they would not because my vin did not show up in the recall. On July 31 of 2025 I got an engine oil low light on my dash, which I took a picture of. At that time I had to add two quarts of oil. Then in August of 2025 I went in for my oil change at Jeff Belzers again and I told them about adding the two quarts of oil and asked again at that time if they could do an oil consumption test and they told me no again because my vin was not on the recall list. I then got another low engine oil light on September 29, 2025 and at that time I added 2 quarts of oil. In October of 2025 I brought my truck to Maur Chevrolet for an oil change and asked them to check my vin for a recall and they said there were no recalls. Then I brought my truck to Maur Chevrolet in November of 2025 for an oil change and I asked if the vin recall had changed and they said no. At this time I was just checking my oil and adding as needed. I took my truck in for an oil change in January of 2026 and asked about the recall again and no changes. Then after that oil change, I was adding a quart of oil every 600 miles. So when I went in for an oil change in April, I asked for an oil consumption test to be done and the service advisor said yes. This was the first positive step I had in this entire ordeal. At the end of the consumption test, which was on June 12, 2026 it was verified that the engine was burning 3 1/2 quarts of oil every 3,000 miles. At that time I had another oil change done and they told me that they would discuss what would happen on Monday June 15, 2026

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
When i first purchased the vehicle off the lot a few years back (its a 21, so probably in 22?) Brand new off the lot minimal miles. Within the first few months we started having issues with the power wanting to shift down. We took it in, the dealership found nothing wrong with it and cleared the codes. This happened a few more times. The last 2 times I took it in. They mentioned that there were recalls on it and could possibly be causing the issue. Took care of that (last august- have docs. to prove it as along with what they did and what we stated). Fast forward now 2 months ago (April of 25) and it starts acting up again and wants to downshift, shifting hard, stuttering and not wanting to drive, the same things we have been complaining about since beginning with lights on etc. However, this time we tried to shut it off and give some down time to get back home. After about 10 mins, we went to start the truck to get it home, and it would not start. We had it towed to the dealership. Once they got it, after 2 weeks of waiting we were finally presented with, the starter went out and the wiring box needed to be replaced (this has to be done before they can look into the original problem again) (because without those 2 things fixed, they wont be able to do) it is now June. I took the vehicle home, due to not having funds to fix right away. After doing some research and some digging, it would appear that the issues that we are having with the truck are issues that are already being recalled on this specific truck and model. However, for mine it is not, because I have the 2.7 l turbo and not the 6.8. THere have been numerous complaints about the known issue.(which i found out is the other wiring by the engine that is being chafed which is causing the wires to break and causing the other box and alternator to go and be replaced). If you replace it fries all again. Why is the 2.6 engine problem thats reported not recalled but rest is and it is known. I also see this online

ENGINE
On June 3, 2026, my 2021 Chevrolet Silverado 1500 LT Trail Boss, which has a 6.2L L87 V8 engine, stalled and shut off unexpectedly while I was stopped at a traffic light on a public highway. The engine died without warning, leaving me stranded in traffic and creating a serious safety risk for me and other drivers because of the chance of a collision. I had to call the police to come and sit behind me to keep myself safe from a collision while I waited for a tow truck. A dealer diagnosed the vehicle with DTC P0016, indicating a crankshaft/camshaft position correlation fault. This points to either an engine timing problem or an internal engine failure. The dealer confirmed the issue and gave me a repair estimate of about $11,000. Both the vehicle and repair records can be inspected if needed. Before the failure, the vehicle showed signs of an engine timing or internal issue and eventually triggered the check engine light with code P0016. After researching, I discovered many reports from other owners with the same 6.2L L87 engine who faced similar problems, including P0016 faults, engine stalling, internal engine damage, and complete engine replacement. While some vehicles with this engine have been part of recalls or special coverage programs, my vehicle is not included, even though it shows the same failure pattern. At the time of the failure, the vehicle has about 140,336 miles. I believe my vehicle has the same defect affecting other 6.2L L87 engines. I ask that NHTSA look into whether more vehicles should be added to any current or future recalls or defect investigations. Thank you for your attention to this matter.

I have fighting this issue since January and have not gotten any help or relief from Chevrolet. This issue caused a significant safety risk and has cost me $12,000. I am writing to formally report a serious safety issue involving my 2021 Chevrolet Silverado that resulted in a sudden loss of power while merging onto an interstate highway. On XXX, I brought my vehicle in for service to replace the upper and lower ball joints, as well as the control arms. I retrieved the vehicle from the repair shop on XXX, and departed the same day for travel to [XXX]. Later that evening, while traveling southbound on [XXX] near [XXX], I stopped at Exit XXX. Upon re-entering the highway and accelerating to merge into traffic, the vehicle began shifting through gears abnormally. While in approximately 6th gear at around 2,900 RPM, a loud banging noise occurred, followed immediately by a significant loss of engine power. At the same time, the check engine light illuminated. Due to the sudden and unexpected loss of power while actively merging into highway traffic, I was nearly rear-ended by another vehicle. I was forced to take immediate evasive action and pull onto the shoulder to avoid a collision. This incident created a highly dangerous situation not only for myself but for surrounding motorists. This failure occurred without warning and directly impacted my ability to safely operate the vehicle in a high-speed traffic environment. I believe this presents a significant safety concern that warrants investigation. Please let me know if any additional information is required. I appreciate your attention to this matter and request that this incident be formally documented and reviewed.

Was on way to trade truck in onb6/6/26 and got a cylinder #7 misfire. Replaced spark plug and wire and moved coil packs around to trace and stayed on #7. Just had recall completed on 9/25/25 and stated that I've heard a rattling noise in engine area. They performed recall and changed to new oil suggested by GM. Dealership said noise was transmission. I told them that was replaced already within last 50k miles under warranty. Drive it for a few days and rattling noise still there. Took back to dealer on 9/30/25 at cost of $200 diagnositc and stated there is a grinding noise under light acceleration like it's metal on metal. Dealer stated that it was the rear seat rattling. There were NO noises in the cab, only coming from outside at driverside motor area. Called GM 10/1/25 to let them know the denial of motor replacement and we wanted 2nd opinion but we would have to pay out of pocket again. On 6/4/26 had to have truck towed to new dealer. New dealer won't make deal on new truck because of this and we have 2 trips already booked and paid for and 1 at end of June. New dealer is putting in service on 6/8/26 to verify cause. I have called GM after making repairs and they said it was between me and the dealer, there is nothing they can do. This is unacceptable! Im fine if they would offset cost and buy a new Chevy truck and we are going to fight to get it made right. This does make us want to change brands even though we've bought 5 Chevys in the last 10 years.

UNKNOWN OR OTHER
After putting our Silverado in park it will not turn to the off position or release the key from the ignition immediately. We have to wait 1-3 minutes without attempting to turn it in the off position and then the key will release from ignition. No warning lamps. No error codes on reader. Repeatable by auto technician who suggested a battery change- our current battery was fine and did not fix the issue. If you forget and try to remove the key in under a minute after parking you have to restart the truck, go back to park and then start the 1-3 minute countdown all over before it will release the key. The truck is in park, the parking brake is engaged (although we tried without using the brake and still won’t release key) This means the trucks battery has to run until it will release the key. Or chance leaving the key in the ignition (still draining battery) since it won’t turn to the off position.

ELECTRICAL SYSTEM
1. An electrical failure from a component of the main wiring harness causes the ECM to respond with Service ESC, Reduced Engine Power, Service parking brake, service traction control. 2. Interstate driving requires maintaining rate of speed to avoid collision. The vehicle is much more difficult to drive as acceleration is very poor and also main safety functions like traction control are disabled. 3. Check engine light stays on until codes have been read. After codes have been cleared, normal driving and usually turning or bumps in the road tend to trigger the recurrence. 4. The vehicle has only been reviewed by the dealership for this issue. 5. No warnings before the failure occurs.

Truck started ticking/clicking a few months back and the ESC or ECS light came on took it to the dealer Carl Black Chevrolet in Orlando, where the was supposed to to fix the problem under the previous owner, my boss who gave me the truck and 30 days after receiving the title the motor is bad. Mileage now is 112,000, the truck has burned the right fuel and had proper oil changes. Now the motor is blown as per a certified mechanic northeast auto and truck service in Ocala. First owner called General Motors to see if they could help and was told it should have gone to a Chevy dealer so they won’t or cant help. Motor is blown on a truck with low miles and this is how Chevy appreciate its drivers who purchase their vechiles. Buy American, they say…wow! On [XXX] the same reading came on again. This time it said service emergency brakes, parked it, went in store to purchase food, came out, started truck, drove 4 miles, parked truck went in to work and three hour later came out and white smoke rolled out the back and inside cab. What the heck! Embarrassing … had to leave truck… Chevy replace this engine, please. Was concerned about it INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2021 Silverado LT trailboss. Catastrophic engine failure. Camshaft bearing and lifter failure. First lifter replacement @ 16,000 miles. Second at 104,000 miles. Was told by GM the 6.2L L87 I have is not affected due to a Canadian VIN. The sticker on the truck says Assembled in Kentucky. Gm charged $18,000 for a refurbished motor. The “new” motor had lifter failure at 12,000 miles. Canada is now included in the recall but I was again told by GM that my engine is not affected due to being built in September 2020. I believe this engine bearing failure goes back further than they like to admit.
