2021 CHEVROLET SILVERADO 1500 Complaints

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 tailgate randomly opens and closes during driving causing contents to fall out of the tailgate and creating a hazard for other motorists and damaging personal property. The tailgate now will not open and there is no manual override to open the tailgate. Certainly a design flaw and now not allowing access to the tailgate. I've contacted 5 local gm/chevrolet dealer service departments and they cannot offer any guidance on how to manually or power open the tailgate. I have a tonneau cover on the tailgate which makes it pretty much unable to access. I'm a firefighter and put my gear in the tailgate and need access asap. Please advise on how I can get GM/Chevy to assist with this issue. A police officer was behind me when the contents fell out of the tailgate on 6/9/25. This has happened several times since and most recently on 1/17/26. This needs addressed asap. Thanks!

The contact owns a 2021 Chevrolet Silverado 1500. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The local dealer was contacted but was unable to schedule an appointment because the service center was fully booked. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure.

I own a 2021 Silverado 1500 6.2 v8. Since October of 2025 this truck has been in and out of the dealership. First engine (Oct. 24, 2025) issue as my teen driver was on the expressway and luckily was able to get off and get safely to an unknown persons driveway. Then the motor seized and died as we tried to drive it home. A friend was able to tow it to our driveway and GM sent a tow truck to pick it up and haul to the dealership. The truck was in the dealership for 2 weeks prior to the first engine failure and "EVERYTHING WAS FINE". Nov 26, 2025 new engine comes in. December 12th SECOND motor was put in and FAILED as cylinder 7 had no compression. Dec 31, 2025 picked up my truck with the THIRD motor. Jan 14, 2026 took the truck back AGAIN for engine ticking, noise, loss of propulsion/speed, running sluggish. Dealer kept it until Jan 21, 2026. Dealer said they drove it and the noise is normal injector noise. They did nothing other than drive it. They will not investigate any further as it wasn't pulling codes or warning lights. It is still not running right and I'm waiting for it to have a major failure. It is not safe to drive. The first motor did not show any warnings either. GM really needs to get this figured out soon. No vehicle with 52,000 miles should have 3 motors put in it. This is not quality work and concerns for safety are real.

Lights appeared on dash, brought to the dealership. Dealership states engine damage due to valve train and a remanufactured engine was installed. This was approved by us for a $2000 charge. This charge included new manifolds, water pump, fuel pump and all associated gaskets

Ignition key fails to release from column lock. It will return to accessory position but not full return for release. Frequent but intermediate problem. Dealer just replaced ignition switch however problem returned same day. (Have not contacted dealer back yet). Restarting the truck and turning the wheel back and forth, shifting to other gears then back to park sometimes works, and sometimes does not. I am often forced to leave the key in the column and lock/unlock truck with remote. No CEL, no other indicators or messages present. 49,515 miles on truck.

I am the owner of a January 2021 6.2 liter Chevy Silverado 1500. I have had multiple issues with this vehicle. Oil pressure control solenoid, many no starts, failure to starts, engine lights, oil lights. Truck started to use an excessive amount of oil before scheduled oil changes. The engine sometimes hesitate and fails to accelerate. The engine became noisy. My mechanic started that the engine is noisy and the oil pressure is at 15 lbs. They said it will need a replacement engine that is not covered under my expired power train warranty. The mechanic stated it's not a matter of if it will go, is a matter of when We are a family of 5 and this is our family vehicle. We feel very uncomfortable driving this vehicle with our family knowing the engine is going to fail at any time while driving. This is a heartbreaking expense that I don't believe that we should have to pay for. We have always maintained our vehicle and have never abused it.

Vehicle: 2021 Chevrolet Silverado Issue: Infotainment system failure after GM-pushed OTA update Description of Problem: On 10/31/2025, my vehicle’s infotainment system attempted an over-the-air software update. The update failed and the screen has been locked ever since, displaying only the message: “Update Failed – Return to Dealer.” As a result: - I cannot access any settings (clock, preferences, system menus). - All warning chimes and signal sounds (turn signal click, seatbelt reminder, back seat reminder, etc.) are disabled. - The backup camera still functions, but no other infotainment features are usable. - The system is completely unresponsive to reset attempts. I brought the vehicle to a Chevrolet dealer, who verified that it was the OTA update that caused the failure, they attempted a reflash but was unsuccessful. They now claim the entire infotainment unit must be replaced at my expense, even though the failure was caused by GM’s own update which I neither approved, initiated, or requested. My vehicle is out of warranty, but this was not a wear-and-tear issue — it was introduced by GM’s software. Safety Concern: The loss of audible warnings and chimes poses a safety risk. Drivers rely on these alerts for seatbelt reminders, turn signal confirmation, and other critical notifications. A manufacturer-pushed update disabled these among other functions including radio, navigation, and all vehicle settings. Resolution Attempts: - Dealer attempted reprogramming on 11/6 (charged $295) but failed and state I need a new infotainment system. - GM Customer Assistance refused to provide goodwill coverage. - Vehicle remains stuck in failed update state as pictured. Request: I am submitting this complaint because GM’s OTA update disabled core safety features of my vehicle along with other basic features such as radio. I believe this is a manufacturer defect that should be investigated and addressed, regardless of warranty status.

Went to put the truck in gear and it will not move the Chevy dealership saids it needs a new transmission and I see that the 21 Silverado has multiple tranny issues I bought extended warranty and they are telling me it might not be covered

Jan 2024 lifters on one side went out. Towed to dealer and had repaired. 9 months later lifters went out again. Had private shop repair it. Less than 3 months later, motor went out. Paid out of pocket to have new motor shipped and repair shop fixed it. A few months later, GM put out the safety recall for 6.2L engine failure.
