On January 3, 2026, I started the truck, but it would not go into gear when I put into drive; I then attempted to put into reverse and same problem. I had to have it towed to the dealership, McCluskey Chevrolet, Kings Automall, Cincinnati Ohio, on Monday, January 5, 2026, this is where I purchased the vehicle on May 14, 2022, with 16,594 miles at time of purchase (estimated), it was towed on a flatbed, and arrived at McCluskey with 60,072 miles. Truck was looked and they found that it needed a valve body. At which time they told me GM warranty expired, over 60,000 miles, really by 72 miles. Ok there is a powertrain warranty then I had to prove oil changes, guess what I'm human and I missed two oil changes so the "extended warranty" McCluskey "gifted me" was void. I then complained I only drove the vehicle 43000 miles and for a 2021 with 60,072 miles this is an issue. Service advisor then went to management and they reduce the cost from est. $4000 to $585 plus tax through a program that GM offers. Picked up repaired vehicle on 1/30/2026, 2/1/2026 engine light came on went to have a veriscan and it found solenoid 3 stuck off & solenoid 4 (the one that was replaced) stuck on. This is an issue on gas 2021 Silverado 1500 and I wanted to report my experience because this is not "primarily" a diesel problem any longer.

Starting back in June 2025 Loss of engine power multiple times. Many times almost hit from behind as I turned onto a highway. Found out vehicle had a stop sale recall at the time of purchase and I had issues with back right tire. Took truck to a tire shop and learned that the wheel was welded in many places and fracture was visible. Finally, got the dealership to pay attention in October to my concerns. They were going to allow me to trade the vehicle out for another one while paying off the bank but that-??s not what they did. They attempted the repair and tried to hand it back to me. 1/27/26 Was recently told this was corrected, and the sales person told me when he picked it up from shop he couldn-??t go more than 30 mph. Dealership management told him not to tell me. I am submitting this complaint for immediate review regarding Ruiz Ranch Motors (Spring Branch, TX) for an illegal vehicle sale, prolonged withholding of my vehicle, misrepresentation of a -??loaner-?? vehicle, and coercive threats involving law enforcement. This matter involves ongoing safety risks, financial harm, and improper dealer conduct affecting both myself and my minor child. Summary of Key Facts (Concise): -?? On June 25, 2025, I purchased a 2021 Chevrolet Silverado (VIN 1GCUYHET7MZ155657) from Ruiz Ranch Motors, financed through Ally Financial. -?? The vehicle was subject to a GM Stop-Sale / No-Sale Safety Recall (NHTSA 24V797000) at or around the time of sale. -?? I repeatedly raised safety concerns beginning shortly after purchase. These concerns were dismissed for months. -?? In November, Ruiz Ranch Motors took possession of my 2021 Silverado under the representation that they were -??working on trade numbers-?? and a solution to correct the experience. Misrepresented -??Loaner / Trade-?? Vehicle: -?? I was provided a 2023 Chevrolet Silverado, represented as a potential trade option, no trade was made (only dealership delay) this vehicle now has a engine light and no cooperation from dealership

The contact owns a 2021 Chevrolet Silverado 1500. The contact was aware that the VIN was included in NHTSA Campaign Number: 24V797000 (POWER TRAIN). The contact stated that while driving 75 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the vehicle pulsated before stalling. The contact was able to coast to the side of the roadway. No warning lights were illuminated. The vehicle was towed to an unknown dealer, where it was diagnosed with transmission failure. The vehicle was not repaired. The vehicle was then towed to another dealer, where the transmission failure was confirmed. The contact stated that the dealer had not inspected the transmission and used a "peephole" to inspect the transmission. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

Component that failed: The valve train system failed due to collapsed lifters in the GM 5.3L L84 engine. The lifter failure caused internal camshaft damage requiring major repair. The failed components were removed by the Chevrolet dealership and should be available through the repair facility if inspection is requested. Safety risk: The engine failure caused a sudden and severe loss of power while driving. The vehicle would not accelerate beyond approximately 45 mph on a 65 mph roadway while en route to the dealership, creating an unsafe speed differential. When attempting to accelerate to pass another vehicle on a two lane road, the engine backfired and immediately throttled back, making it unsafe to complete the pass. The check engine light illuminated at the exact moment the vehicle lost power during the passing attempt. This sudden propulsion loss during an active maneuver created a hazardous driving condition. Dealer confirmation: An authorized Chevrolet dealership diagnosed collapsed lifters which damaged the camshaft and confirmed this as a known failure pattern in GM L84 engines. Inspection by others: Vehicle was inspected and repaired by the dealership. No accident occurred, so no police or insurance inspection was involved. Warnings or symptoms: No prior warning lights appeared before the passing event. The check engine light came on during the failure while accelerating. Additional context: This failure aligns with widely documented lifter collapse defects in GM 5.3L L84 truck engines. The breakdown was not caused by maintenance or wear and tear but by premature internal component failure known across this engine platform.

The powertrain transmission system, specifically the torque converter, failed on my 2021 Chevrolet Silverado at approximately 66,000 miles. The vehicle was taken to and inspected by a GM-authorized dealership, Pellegrino Chevrolet, on January 7, at which time the dealership diagnosed a failed torque converter and formally recommended a full transmission replacement due to the risk that metal debris from the failed converter may have contaminated the transmission; the vehicle and affected components are available for inspection upon request. This failure presents a safety risk due to the potential for loss of power, unpredictable drivability, delayed or failed acceleration, or sudden transmission malfunction, and this vehicle is my family-??s primary transportation and is used to transport three child car seats. The problem has been confirmed by the GM-authorized dealership and additionally reviewed by four independent mechanics, all of whom advised that replacing only the torque converter would be insufficient. The vehicle has been inspected by the dealership and documented under General Motors Case #87048318; it has not been inspected by police or insurance representatives at this time. Prior to diagnosis, the vehicle exhibited abnormal transmission behavior and drivability symptoms consistent with torque converter failure, which prompted inspection and worsened leading up to the dealer diagnosis.

1- Tailgate keeps opening by itself. It has opened while driving down the highway and things fell out of back of my truck almost causing an accident. It has opened while sitting in my driveway after I have turned the truck off and gone inside. I have reported this to a dealer they said my vin is not on the recall list. I would like my VIN added since it is obviously an issue with the Silverado's. 2- I recently has to bring my truck to the dealer for the transfer case sounding like there were bolts in a blended and a pinging sound by the bell housing while in park. They stated it was the front axle and fixed it saying it was a power train thing. The noise is back and now out of warranty.

Not sure of exact date I believe it was right before Thanksgiving. The truck started shuttering and vibrating. It feels like we are driving on a gravel road. the manual said to change transmission fluid between 45,000 and 60,000 so we took it to the dealer. that is what we did hoping that would fix the problem. but it did not so we took it back and they kept it for 3 weeks they said no codes came up and they said the tires needed balancing so we let them do that but the problem is still there. they say there is no recall on it. we did some research and found information stating Chevy is having problems with the transmission. as of now we only have 45,608 miles on it. It is riding worse now.

2021 Silverado 19,000 miles no indication of failure at a busy intersection about to go thru intersection and engines started knocking, multiple check engine lights on. Luckily got thru the intersection and to my place of residence which was very close by. Truck was towed to Chevy dealer. Dealer found 3 bent push rods, 3 bad valves. This engine had the lifters fail completely out of the blue. Oil changed at the dealer, meticulously maintained. Dealer only replaced the faulty bank of lifters due to mileage, seriously if it was under 16,000 they would replace all of them. This is unacceptable. This truck left me almost stranded in a busy intersection, lucky I knew well enough to keep going versus getting T-boned. I just think GM needs to do something about this. Now fast forward to 41K and I'm at the dealer same symptoms except this time my warranty is running up soon and being forced into an extended warranty. There are plenty of online claims, chat rooms, posts, etc to warrant this as a safety issue.

6 months and 20,000 miles after purchasing the 2021 Chevy Silverado custom 4x4 with the 8 automatic transmission and the 2.7L turbo charged engine with 32,000 original miles on it from Volume Chevrolet in Forsyth GA I noticed the transmission was jerking when the truck was first crunk and warming up after about 10 minutes and once it got to 8 mph after a while when the temperature gauge was half way up it would stop and when you slowed down from 55 mph to about 5 MPH to make a turn it would suddenly jerk again, I reported the issue to the dealership service mechanic shop reps during every oil change and they assured me that it was normal and that it would stop happening when I let the truck warm up for about 30 minutes prior to driving, once the factory power train warranty ran out, they informed me that it needed a transmission service and they would have to keep it a few days and it would cost around $800 or so to get it done, the purge pump on the emissions system has a factory defect and I received a recall letter about it 6 months after purchase and they are refusing to replace the purge pump until they perform a full diagnostic first even though they have done a scan diagnostic and it shows the purge pump failed and I have just been struggling with all the cost of living and increased prices I can't afford any kind of costly repairs right now and my truck now has 120,350 miles on it and the issue is getting worse to the point that I am sure that the transmission valve body and some other sensors and control modules are failing, this is not a single issue and other dealerships have said that the transmission was starting to have problems in other trucks at around 55,000 miles and some earlier than 55,000 miles, I believe that this is an ongoing transmission issue with the 2.7L turbo charged engine in both the 4x4 and 2x4 models and with the 8 speed automatic transmission In general, I have talked with several other owners and they have had similar issues.

Component is transmission. Stutter vibrate shift while driving. There is a recall on the 2021 Chevy 1500 Silverado which is exactly the issue we are having from our 2021 Silverado. The VIN for our truck is falling under the current recall. Chevy wants to charge to even diagnose the problem which has to be done with a dealer and not a private place. That is absurd and puts our safety at risk should the vehicle stop functioning while driving it. The dealer ship has inspected the vehicle for the yearly inspections which is interesting since this has happened and been complained about since purchase.

I was stopped at a stop light and all of a sudden, the engine just revved amd revved and no drive only reverse, and it happened 4 times until tonight, 11/11/25 @ 8:38pm I am stuck at another red light and have to back my truck up to Home Depot and get a tow. Only a 5 year old truck with 71122 miles and ALWAYS WELL MAINTAINED WITH PAPERS AND GOES OUT ON ME. NOT ACCEPTABLE GM! You make things and used to be solid, like a rock trucks but now I feel robbed as a long time Chevy fan/enthusiast but I may have to change manufacturers unfortunately.

The truck started to vibrate badly. Brought it to the dealership and have to replace the 6.2 L engine. I was happy to make it home without it breaking down. The truck only has 67,000 miles on it.

My transmission started to make a rumbling sound intermittently while I was on the highway. It happened during normal highway speed and not dependent on acceleration or deceleration. I brought it to the dealership with 84,000 miles and they dropped the transmission pan. No metal found in the fluid. The issue was with the torque converter. I had my oil changed 1.5 weeks prior with a 21 point inspection. I was curious if there was a TSB for this issue. I haven't been able to find a recall notice for this issue.
