2023 Chevrolet Silverado 1500 Problems

Engine failed 6k miles after inspection and oil type changed to 0w40 from GM dealer Roger Dean Chevy Cape Coral FL

On June 27th 2026 at approximately 3am, I was driving my Chevy Silverado Trail Boss with 6.2 engine, it suffered a sudden catastrophic failure and it completely seized while in motion. There were no warning or signs given while vehicle was in motion. This resulted in an immediate highly dangerous loss of propulsion on a dark 2 lane road. The vehicle would not crank and had to be towed to Estero Bay Chevrolet.

Hard shifting, Shuddering, clunking sound when shifting between drive and reverse. Was informed by Ken Ganley Chevy in Brookpark , Ohio that the valve body inside the 8speed transmission is faulty and is on a nationwide backorder.

I am filing a formal complaint regarding General Motors' handling of a critical vehicle component that has left my vehicle and many others in an unsafe condition. For more than over a one month, I have been waiting for a replacement gear shift module that is currently on backorder. During this time, I have learned that numerous General Motors customers are experiencing the same issue and are also waiting for this part to become available. My primary concern is that this appears to be more than an isolated parts shortage. If so many vehicles require replacement of the same safety-related component, General Motors should be evaluating whether this issue warrants a safety recall or, at a minimum, notifying affected customers of the potential risks. The gear shift module is a critical component that affects the safe operation of a vehicle. Allowing customers to continue driving vehicles that may have a defective gear shift module without providing a safety notification or timely repair raises serious concerns regarding public safety. I respectfully request that the NHTSA investigate this matter and encourage General Motors to: Explain the reason for the extended backorder of this critical component. Provide customers with a reasonable timeline for obtaining replacement parts. Determine whether this issue should be addressed through a formal safety recall or customer safety notification. Offer appropriate assistance to customers whose vehicles have been affected by this prolonged delay. Customers should not be expected to operate vehicles that may present a potential safety risk while waiting indefinitely for a critical replacement part.

A valve on the 3.0L Duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for GM and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that GM knows is their fault.

“Service transmission now unable to shift soon” message. Vehicle is stuck in park. Message appeared in May. Transmission stuck shortly after. Safety is at risk due to transmission being unable to shift due to faulty module that is widely reported and known to Chevrolet.

a week ago I was backing up and this truck is supposed to be equipped with a "REAR CROSS TRAFFIC BRAKINGF – When in Reverse, the system warns of detected cross-traffic approaching in either direction and provides alerts and hard emergency braking to help reduce the severity or help avoid collisions at very low speeds", I backed into another vehicle that was parked behind me. I did not receive any warnings and the automatic braking did not activate. I was fortunate that I was going slow and only damaged the other drivers door and my tailgate and bumper.

The left front turn signal becomes inoperable at times. The foreword collision indicator warning will come on unprovoked at times. Both conditions correct when you cycle the ignition switch. I consider the turn signal problem a safety issue because it happens with no warning and oncoming traffic may not know I am turning left or changing lanes. When the foreword indicator appears, I doubt the system is operable.

Multiple times the truck has stopped running while driving. Once one the highway, once in an intersection, another time in a parking lot. It has not started when I have tried to turn it on. All the times I have called AAA. They have checked the battery and there is no battery issue. Twice AAA has come out, once the police have come and sat behind the truck to keep me safe. After about 10 minutes of the sitting with the truck off I can restart it and drive. Upon research, other Chevy trucks of similar age have a recall for a failed fuel pump module. This is the issue. If it is a known issue, and causing a dangerous situation it should be recalled on all trims of Chevy trucks. I will be getting this fixed, but don’t feel I should incur the $1,000 expense for a known defect.

Was making a left turn with a left turn street light green for me to turn across an intersection. Pickup stalled in the middle of the intersection and would not start. With the help of another person we manually pushed the pickup out of the intersection and onto another side street. I received an email at that exact time from General Motors showing a code of P129F which is the Fuel Pump Power Control Module. I am a [XXX] man stranded in 90 degree heat with no AC or shade to get under. My safety was put at risk in the above instance but more so if I had been entering IH 10 into traffic traveling 70MPH and my truck had just stopped running without any warning. This is a known problem as described in GM Service Bulletin 24-NA-139 with both the NHTSA and DOT. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 50 MPH with his wife and grandchildren inside the vehicle, the check engine warning light, collision warning light, and several other unknown warning lights were illuminated. The contact stated that the message "Braking System Failure - Do not exceed 62 MPH" and the trailer brake message was displayed. The contact continued to drive the vehicle; however, whenever the brake pedal was depressed, the vehicle failed to slow as intended. The vehicle was taken to a dealer where it was diagnosed and determined that a software update was needed. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 54,000.

On 4/09/26, while visiting friends near the border in [XXX] from [XXX] and driving on a dry paved road we lost the ability to stop the truck and engage the brake system. To avoid a crash, I drove the truck up onto the sidewalk and closed my eyes. Fortunately we did not crash into stopped cars but the truck does not work and it has body damage to all sides. Now when the key is in forward collision system unavailable, service traction control and service ESC shows on dash. Truck is unsafe and a hazard on the road. A call to GM has been made waiting on a response. Gm case#XXX. Truck is 2023 with 62k miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Upon purchasing a used 2023 Silverado, on the first night of ownership, I found the headlight on the passenger side to be defective. The high beams activated approximately a full second slower than the driver's side. It took me a few days to confirm what I was seeing, where I immediately reached out to help from the Chevy dealership it was purchased from. After back and forth, the dealership refused to fix this saftey item as it was "still operational just not 100%" or something to that affect (not a direct quote). The extended warranty company doesn't typically cover headlight housing. The dealership locally says both headlights need replacement. Chevy Corp is involved, under claim 104164057. I've brought to their attention that I have found several reports of this defect online for similar vehicles and model year. My contention is that, particularly due to being the passenger side, this malfunction could lead to accidents and collisions due to distraction of troubleshooting, and the delay of lighting on the side where animals and night hazards typically come from. I've read online reports of these headlights may take up to 3 seconds between sides to both activate, with one side running slower than the other, and eventual failure where the switching mechanism will get stuck. A Chevy dealer confirmed the defect and recommended replacement of both headlights, at my cost, for approximately $4000. Chevy is still investigating and trying to find a conclusion with the dealership, but I contest that I have malfunctioning saftey equipment that could lead to harm or injury, and at the moment, both dealer and manufacturer have been unwilling to resolve the issue. The failure occurs both in auto-headlight and manual modes.

Tailgate unexpectedly opened when driving. Switch on and off when parked and drained battery

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the tailgate lowered unexpectedly while driving at various speeds, and occasionally closed unintendedly. The failure also occurred while the vehicle was parked and turned off. The vehicle was taken to the dealer, and the failure was demonstrated. The tailgate switch was replaced. The contact became aware of a Canadian Recall, ID Number: N232426400, for the tailgate failure. The manufacturer was made aware of the failure; however, no repair was performed. The failure mileage was approximately 60,000.

Truck will hard shift and bang into gear while driving. This usually happens when slowing then starting up again. happens at all speeds on highway, so hard it lunges me forward. condition getting worse. random times my windshield wipers will just come on ( I do not have rain sensors) the switch is in the off position and wipers will just come on and I have to turn them on then turn them off to get them to stop.

What component or system failed or malfunctioned, and is it available for inspection upon request? Glass sunroof blew outwards driving 60mph on the highway. No other vehicles were around and I did not see anything impact the vehicle. The glass was broken outwards and created an 8” by 8” hole in the sunroof glass. There was no extreme temperature differential, approx. 55 degrees outside. It has been repaired and not available for inspection. How was your safety or the safety of others put at risk? It sounded like a gunshot inside the truck, causing extreme distraction at highway speeds. Luckily the interior shade was closed and caught the glass, but if it was open all of the glass would have fallen on the passengers. Has the problem been reproduced or confirmed by a dealer or independent service center? No the dealership did not consider it a manufacturing defect. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Insurance inspected the vehicle and it was covered under a glass claim. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No indication prior to the incident at all. It happened out of nowhere.

When driving normally OR pulling a camper (same day), power steering seems to "stick" as I exit either a moderate RH or LH corner. I must apply extra effort to the steering wheel to straighten out, and that invariably leads to an over-correction and departure into either the shoulder or the opposite lane. Problem is not sensitive to speed or weather conditions. The symptoms are not necessarily worse when pulling a camper, but the consequences are much more drastic and losing control of the vehicle feels much more imminent than when driving just the truck. Because the problem comes and goes so quickly, I can be applying force to straighten the wheel when suddenly, no force is required and the truck veers either left or right. I see no warning lights, nor do I see any messages displayed. I have not yet had the opportunity to get the truck to a mechanic. I'm not confident that I can safely drive to a repair facility, as the steering is so unpredictable.

My 2023 Chevrolet Silverado 1500 experiences an intermittant, uncommanded mechanical drivetrain lockup and severe binding when accelerating from a complete stop. The vehicle rolls fine in a straight line for several feet, but the exact moment the steering wheel is turned slightly (a couple degrees), the drivetrain violently binds up. This creates resistance in the steering and acceleration, as well as a severe physical and audible metallic clunking slam and massive shockwave vibrations felt directly through the steering wheel, floorboards, brake/gas pedals, and driver’s seat. During the last event, the vehicle threw a "Service 4 Wheel Drive" dash message and refused to shift out of "Auto" mode back into 2WD. Because this is a pure mechanical interference/binding issue, it does not consistently throw active electronic trouble codes. A standard OBD2 code scan will show nothing. After turning the vehicle off for several hours and testing again, the problem persisted. After towing the vehicle to a dealership (6/10/2026) it sat for at least 5 days before dealership service looked at it. By this time, the active warning lights cleared. My initial servicing dealership refused to perform physical hardware or fluid diagnostics under my factory warranty, stating they would not look at the vehicle unless I paid $860 out-of-pocket or until the drivetrain "completely grenaded" on the road. Because this uncommanded lockup restricts my ability to steer the vehicle safely from a stop, it presents an immediate crash hazard. At the direction of General Motors Corporate, I am escalating this issue and moving the vehicle to a secondary certified facility (Feldman Chevrolet of Novi) on June 23, 2026, for a formal physical hardware and fluid tear-down inspection.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the tailgate was constantly opening unintendedly. The failure also occurred while the vehicle was parked overnight, causing the battery to drain. Additionally, the contact stated that the rearview camera was inoperable. The vehicle was taken to the dealer, where it was diagnosed, and determined that the tailgate switch and rearview camera had failed due to water intrusion. The dealer replaced the tailgate switch; however, the rearview camera was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 38,000.

Driving at highway speeds the message center prompted us to restart the truck and put itself into neutral. Upon attempting to do so, the message center read conditions not correct to shift. We were traveling in a single lane highway thankfully on a decent where we coasted into a parking lot. The truck list all power steering and brakes. We turned the truck off and attempted to restart. Lights were randomly flickering on and off, but the starter couldn’t turn the engine over. After 3 hours of waiting on Chevrolet roadside assistance we obtained our own tow service. The truck tires had seized up causing the driver to drag the truck into the flatbed. The emergency brake kept resetting itself. The following day 7/13 Chevrolet had the truck towed to the dealership. On Monday 7/16 we were informed the engine had catastrophic failure with less than 24k miles. This is the second major engine breakdown as the first was at 5k miles where one side of the engine had collapsed lifters. Engines are on back order but in reviewing other experiences the replacements experience the same issues. The truck is not a safe vehicle to drive.

Vehicle sways/wobbles on grooved pavement. Magnified immensely when towing a trailer. Threatens to pull you into other driving lanes. Service technician and service manager at dealership state it is a known condition with the type of tires Chevrolet has put on the vehicle and that Chevrolet is refusing to do anything about it. Multiple dates and is repeatable.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving approximately 70 MPH and hauling a small box trailer, the vehicle slid several times. There was no warning light illuminated. The contact pulled over to the side of the road temporarily and resumed driving; however, the failure recurred several times. The contact pulled over to the side of the road. The manufacturer was contacted and informed the contact that towing assistance could be provided for the vehicle but not for the box trailer. The contact decided to continue driving the vehicle to the residence while the manufacturer remained on the phone with the contact. The contact stated that upon test driving the vehicle the following day, the vehicle operated as needed. The vehicle was taken to the dealer, where it was inspected, and the dealer removed the valve body of the transmission per the manufacturers' instructions. The dealer then informed the contact that metal shavings were found in the transmission pan. The dealer replaced the transmission. The contact stated while driving at various speeds, the rear end of the vehicle continued to make an abnormal humming sound. The vehicle was taken back to the dealer, where it was test-driven, and the dealer determined that the rear end of the vehicle needed to be rebuilt. The vehicle was repaired. Additionally, the contact stated that while his wife was driving 40 MPH on a wet road, the vehicle inadvertently slid off the road and drove on the grassy area covered with snow. The contact's wife steered the vehicle and missed a ditch; however, the rear passenger's side of the vehicle and the rear passenger's side tire struck a pole. The air bags did not deploy. The driver did not sustain any injury. The driver exited and inspected the vehicle. The driver was able to continue driving. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 23,000.

There is a noticeable clunking or knocking noise from the rear suspension, possibly the leaf springs

The contact's husband owns a 2023 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at approximately 60 MPH, and shifting gear, the vehicle lost motive power for 15-20 seconds. The Forward Collision Avoidance warning light was illuminated. On another occasion, while her husband was driving at an undisclosed speed, the driver assist function was activated, an error message was displayed, and the vehicle failed to operate as intended. The vehicle was taken to a dealer and the contact was informed that the transmission fluid needed to be flushed, and the TCM module needed to be updated. The vehicle was repaired, but the failure persisted. The manufacturer was notified of the failure. The failure mileage was 42,000.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at 15 MPH, the brake pedal depressed to the floorboard and failed to stop as needed. No warning lights appeared on the instrument panel and the forward collision avoidance feature failed to operate as needed. Due to the failure, the contact crashed into another vehicle. The air bags did not deploy upon impact. Neither the contact nor the passenger sought immediate medical attention; however, the other driver did state they would be seeking an X-ray. A police report was filed. Due to the accident, the vehicle was towed to an independent mechanic where it remained in their possession. The dealer was notified of the failure but offered no assistance. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 11,000.
