Acceleration & Cruise Control complaints by model year
Safety Issue. The raised cruise control speed set button on the steering wheel is prone to being touched when rotating the steering wheel while making sharp turns when driving through parking lots at low speed. If the distance cruise was previously set at say 45 mph the last time it was used, and the set button is very briefly hit upward when rotating the wheel through your hands to the left, it can inadvertently cause the truck to start accelerating to that previously-set speed. The cruise button needs to be programmed such that at certain steering angles it will not respond to inputs. This is very dangerous. I ave had this happen to me at least 5 times. Hitting the brakes stopped the acceleration. I reported it to the dealer as a potential engine surge but they could not reproduce it. I just recently realized what was happening. I believe this can easily be addressed by a steering angle lockout of the button. Other issues: Drivetrain vibrates occasionally and shifts very hard (drivetrain literally slams through gear change) when leaving driving from a stop a slow speeds. Dealer cannot replicate. This diesel truck gets very poor mileage possibly from spending too much time in regeneration mode. Truck is super sensitive to fuel. Mileage varies drastically from fill up to fill up depending upon station. I believe the fuel cetane content affects regeneration in unexpected ways. I buy fuel at name brand stations but mileage varies drastically from vendor to vendor. Mileage average goes down to about 11 mpg much of the time due to time in regeneration. Dealer has no comments. I know HD trucks don't have official mileage ratings but this is just crazy. I drive light on the accelerator. Rarely achieved up to 21 mpg but average mileage runs about 11-12. I believe this to be a fault with these trucks as I have read complaints from many others. The infotainment system frequently loses all audio, including turn signal sound, nav. GM has no fix. Possibly software.
NHTSA complaint #11755555 — an unverified report by a vehicle owner.
I was driving down the road at approximately 55 mph when all of a sudden, my truck decelerated and a warning signal displayed on my dash indicating my speed was being forcibly reduced to approximately 30 mph. Fortunately, I was on a rural road versus the interstate. I pulled over and had an OBD2 reader. The reader indicated I had a P-2138 error code from a "voltage correlation error between the two Accelerator Pedal Position (APP) sensors". I was able to limp along with emergency flashers to return home. After driving approximately 10 miles, the "issue" resolved itself. I have since replaced the gas petal assembly after learning this is a common failure on many years of the Chevy Silverado series.
NHTSA complaint #11722483 — an unverified report by a vehicle owner.
When driving, between the speeds of 40-50mph, the wheels would lock up without warning. This happened 4 times during the month of January, sometimes in 4wd. This occurred at speed when the vehicle seemed to be upshifting. Control of the vehicle would be lost during the lockup as the wheels would stop rotation entirely and rather violently. Check engine light came on after the 4th incident, reducing power and a code of P0747 "Pressure Control Solenoid "A" Stuck On". The transmission valve body was repaired by the local Chevrolet dealership under powertrain warranty. This is a known issue on previous years of this truck with the same transmission but has not been expanded to cover this vehicle. Thankfully, I was able to maintain contorol and was not in traffic when this occurred. I notified the dealer that the vehicle was shifting very hard during the last visit but no codes or issues were found at that time indicating an issue.
NHTSA complaint #11716445 — an unverified report by a vehicle owner.
I own a 2021 Chevrolet Silverado 2500HD Duramax diesel with approximately 100,300 miles. The truck began displaying a “Service Emissions System” warning and a countdown message that in a certain number of miles the vehicle will be limited in speed (for example to 65 mph). GM’s own Duramax diesel owner’s supplement explains that when a “Service Emission System” message appears it is accompanied by a distance-until-speed-limit countdown and that the truck will progressively limit speed first to about 65 mph and then to about 55 mph if the condition is not corrected, telling the owner to see the dealer. This creates a safety risk because the derate can occur while driving on highways or rural roads, where an unexpected limit on maximum speed can interfere with merging, passing, and keeping up with traffic. This is our only vehicle, and we must use it for important medical appointments, including cardiology and surgery-related visits. The condition started only about 300 miles beyond GM’s 5-year / 100,000-mile powertrain warranty. I opened a case with Chevrolet / GM Corporate (Service Request No. XXX) and took the truck to Sons Chevrolet in Columbus, Georgia on November 17, 2025 for this issue and a rear wheel lockup recall. The dealer kept the truck from about 9:00 a.m. to 3:00 p.m. and indicated they might need to keep it for at least two more days, but I was not given a clear written explanation of the diagnostic trouble codes or a firm repair plan. Because GM’s own manuals describe this “Service Emission System” message together with speed-limit countdowns, and because the vehicle can actively limit speed on the road if the fault is not resolved, I am concerned this represents a broader emissions/derate defect on late-model Silverado HD Duramax trucks. I request that NHTSA review similar complaints and consider whether further investigation or a safety recall is warranted.

NHTSA complaint #11700011 — an unverified report by a vehicle owner.
The contact owns a 2021 Chevrolet Silverado 2500. The contact stated that while slowing down and coming to a stop, the accelerator pedal was depressed while in drive; however, the vehicle started to roll backwards. The contact depressed the brake pedal to prevent the vehicle from rolling backwards, and the RPM became elevated to 5,000 RPM. The contact immediately turned off the vehicle to prevent the RPM from continuing to increase. The vehicle was shifted to park, restarted, and then shifted to drive(D) and the brakes released. While releasing the brake pedal, the failure reoccurred. The vehicle was immediately turned off and towed to the residence. The dealer was informed of the failure of the clutch pack, which was welded together from friction. The dealer scheduled an appointment; however, the vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 100,000.
NHTSA complaint #11698898 — an unverified report by a vehicle owner.
I am writing to express my serious concern and frustration regarding the unresolved recall on my 2020 Chevrolet Silverado 2500 (VIN: [XXX] ). Despite multiple visits to multiple dealerships, I was repeatedly told that the necessary parts to complete the recall repair were on back order and instructed to “wait for parts.” No interim solution or assistance was ever offered. As a result of this delay, my vehicle broke down without warning, leaving me stranded on the side of the road. This created a hazardous situation and significant disruption to my day. To make matters worse, I had to pay out of pocket to have the truck towed to a repair shop in an effort to get it operational—an expense I should never have incurred given the known recall and repeated attempts to have the issue corrected by Chevrolet. I have been a loyal Chevrolet owner and have always trusted the brand for its quality and dependability. However, this delay and lack of proactive support is causing significant inconvenience and eroding that trust. This situation is unacceptable for several reasons: 1.Safety Risk and Recall Obligation: Chevrolet acknowledged the defect by issuing a recall, yet I have been forced to operate a vehicle that does not meet your own safety standards for months. 2.Repeated Service Attempts with No Resolution: I followed the proper process and visited an authorized dealer multiple times, only to be turned away each time with no solution beyond “wait for parts.” 3.Breakdown and Financial Loss: The vehicle failure and subsequent towing expense are a direct consequence of Chevrolet’s inability to provide timely parts or alternative accommodations.

NHTSA complaint #11684509 — an unverified report by a vehicle owner.
Component/System: The Allison 10‑speed (10L1000) transmission valve body catastrophically failed on [XXX], while driving Sunday afternoon down Galveston Seawall Blvd. The truck abruptly dropped from 45 mph into limp mode in heavy traffic, forcing me to pull into the bike lane to avoid being rear‑ended. The vehicle remains at Classic Chevrolet (Galveston, TX) awaiting the OEM valve body—which is on national backorder—and the complete transmission assembly is likewise unavailable. The failed valve body and transmission are available for inspection upon request. Safety Risk: Unexpected limp mode and gear lock‑up in heavy traffic create an immediate risk of rear‑end collisions or side impacts as surrounding drivers have no warning of sudden deceleration or loss of drive. Reproduction/Confirmation: Classic Chevrolet diagnosed and confirmed the failed valve body on May 12, 2025. Their service advisor and my assigned GM Case Agent (#[XXX]) have both acknowledged the defect but report no parts available for repair. Inspections: The vehicle has been inspected by Classic Chevrolet under warranty. GM Customer Care has reviewed my service orders and correspondence. No police or insurance inspections occurred, as no collision ensued—however, the roadside inspection at Classic Chevrolet confirmed the mechanical failure. Warnings/Symptoms: There were no prior warning lamps, messages, or symptoms before the failure. The valve body failure occurred without any advance indication.

NHTSA complaint #11671056 — an unverified report by a vehicle owner.
In 2024, I noticed that my truck was experiencing rough shifts. It felt as if the back wheels were jerking over uneven ground, even though the vehicle was on a flat surface. In November 2024, my sister sent me an article about General Motors' massive recall due to rear wheel lock-up, which increased the risk of crashes. I contacted GM and learned that my truck was part of the recall. I reported the issues my truck was exhibiting, and GM instructed me to reach out to my dealer about the problem. However, I was informed that they did not have the parts to fix the issue and had no idea when they would receive them. I asked GM if they would provide me with a rental vehicle, but they declined, stating that if they offered a rental to me, they would have to provide one for others as well, which was not feasible due to the large number of affected vehicles. I explained that my truck is my daily driver for work, and I frequently transport my grandchildren in it. Driving the truck was hazardous given the issues it was already exhibiting. I was told to contact my dealer, and since my truck was under warranty, they should provide me with a rental. When I requested to speak with a manager, I was informed that they would only reiterate the same information. I then contacted my dealer, Sapaugh GM Country, located at 1435 McNutt St., Herculaneum, MO. I was informed that they do not have the parts. but they did a minor tweak which has caused more damage to my powertrain and engine.

Replaced with NEW OEM Part(s) - APP, Electrical Throttle Body and M15 Fuse - which did NOT fix issues and now due to safety concerns (further damage to vehicle and personal preservation) will be towing to dealership for diagnosis. Believe to be a known WIRING issues most likely due to WATER exposure/ SHORT in Connectors. - See IP, ECM/PCM and possible false activation to the APP circuit. This should be a RECALL due to the severity of mechanical issues of the malfunctioning system.
NHTSA complaint #11633203 — an unverified report by a vehicle owner.
While using adaptive cruise control, the system can detect a vehicle and immediately apply the brakes or slow down. In some cases, it may detect a vehicle (the vehicle icon appears) and trigger an immediate red collision light flash, followed by automatic braking. However, during these events, there were no cars ahead of the vehicle. There was no obstruction of sensors or cameras, and the incidents occurred in various weather conditions, including rain, snow, and clear days, both during the day and night. If the road is slick or slippery, this could potentially lead to a loss of control. Additionally, if another vehicle is following closely behind, it could result in a collision.

It is a transmission control module wear a lobster transmission into a Garin. Will not let you speed up or speed down and it is unsafe and GM IS making us pay for the bill. The contact stated transmission control module all across the country on back order, you cannot get a dealer to get you one within six months GM should have to do something about this.
NHTSA complaint #11539801 — an unverified report by a vehicle owner.
The infotainment center seems to malfunction and push buttons on it's own or not respond to input, which seems related to a more serious problem I experienced where the gauge cluster was not reading anything out when I was driving, including not knowing what speed I was at or what gear I was in. I had to turn the vehicle off several times and restart it several times before the issue resolved.

WHEN VEHICLE IS ACCELERATING ANYWHERE FROM 30-50 MPH, THE TRUCK LOSES POWER FOR SEVERAL SECONDS, AND STARTS SPUTTERING OR CHUGGING. THE RPM ON THE DASH STARTS BOUNCING UP AND DOWN. THIS GOES ON FOR SEVERAL SECONDS AND TRUCK SLOWS DOWN. IT THEN GOES AWAY AND CAN CONTINUE DRIVING. HOWEVER, WHEN TOWING TRAILERS, THE EFFECT IS ONLY INCREASED AND THE TRUCK SLOWS DOWN EVEN MORE.
