2023 Chevrolet Silverado 1500 problems

ENGINE

On [XXX], my 2023 Chevrolet Silverado 1500 ZR2 (VIN: [XXX]) underwent GM's safety recall service for the 6.2L L87 V8 engine (Recall N252494000 / Special Coverage N252494003). The vehicle passed dealer inspection and received the prescribed higher-viscosity oil and calibration remedy. On [XXX], at 25,287 miles—less than five months and a few thousand miles after the recall was performed—the engine suffered a catastrophic internal mechanical failure, resulting in a sudden and complete loss of propulsion while I was getting off of the freeway. I had to coast to a stop on the side of the road. I had it towed to Murcock Chevrolet. The vehicle was serviced at Murdock Chevrolet (Woods Cross, UT), where technicians confirmed the internal failure and completed a full engine long-block replacement under GM Special Coverage warranty (Invoice total: $10,852.26). GM's initial recall remedy failed to prevent catastrophic failure, posing a serious safety hazard due to unexpected propulsion loss while operating the vehicle.

FUEL/PROPULSION SYSTEM

Main bearing failure at highway speed. Engine replaced by GM under warranty. Vehicle had the recall service done prior to the failure, the recall test and different oil was inadequate to predict or prevent this failure. Vehicle was serviced by the dealer for all oil changes on time.

VISIBILITY/WIPER

I needed a replacement driver-side windshield wiper arm for my 2023 Chevrolet Silverado 1500 LTZ Z71 with factory rain-sensing wipers. GM's electronic parts catalog directed the Chevrolet dealer to part #23387855. The dealer physically compared the part to my original arm and confirmed it was the wrong shape and would not fit. The dealer opened a formal Catalog Omission/Error (COE) ticket with GM. I was then informed that GM redesigned the wiper arm on my truck. The correct redesigned arm has been ordered, but I was told there is no estimated availability date and that it is not currently available through GM dealerships or GM's parts distribution/warehouse system in North America. This is a safety concern because a damaged or failed wiper arm could leave an owner without proper windshield visibility during rain or severe weather. I am also concerned that the passenger-side arm may have the same catalog and availability problem, although this has not yet been confirmed. I am requesting that NHTSA investigate whether this issue affects both wiper arms and other 2023 and newer Silverado 1500 trucks with this wiper configuration nationwide.

FUEL/PROPULSION SYSTEM

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.

FUEL/PROPULSION SYSTEM

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)

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

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.

STEERING

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.

EXTERIOR LIGHTING

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.

ENGINE

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.

POWER TRAIN

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.

ENGINE

On Sunday, July 12, 2026, the 6.2L V8 (L87) engine in my 2023 Chevrolet Silverado 1500 ZR2 seized and locked up completely, resulting in total loss of propulsion. I was driving at 65 MPH when it felt like the transmission was slipping and I lost power and coasted the truck to the side of the road. COMPONENT: Engine (6.2L V8, RPO L87) — connecting rod/crankshaft failure consistent with Safety Recall N252494001 (NHTSA Recall 25V-274). The vehicle is available for inspection. It is currently at Cable Dahmer Chevrolet, where it was towed on July 13, 2026, and remains inoperable. SAFETY RISK: The engine seized during operation, causing sudden and complete loss of propulsion in traffic. This is the exact failure mode identified in Recall 25V-274 as increasing the risk of a crash. CRITICAL DETAIL: This vehicle previously underwent inspection under Safety Recall N252494001 and PASSED on Feb 3rd 2026 at VAN Chevrolet in Kansas City. GM deemed the engine non-defective and issued extended warranty coverage of 10 years/150,000 miles under the associated special coverage program. Despite passing GM's recall inspection, the engine suffered catastrophic failure. This appears directly relevant to NHTSA's open recall query regarding the effectiveness of GM's recall remedy. DEALER CONFIRMATION: A technician at Cable Dahmer Chevrolet has verbally confirmed the engine is locked up/seized. Formal diagnosis is pending master technician sign-off and submission to GM, expected the week of July 20, 2026. The manufacturer has not yet inspected the vehicle. WARNING SIGNS: No warning lamps, messages, or symptoms appeared prior to the failure. The engine failed without warning

EXTERIOR LIGHTING

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.

POWER TRAIN

While shifting my vehicle from Park, a "Service Transmission" warning message appeared on the dashboard. The warning would illuminate and then disappear, but the vehicle continued to shift into the other gears. At the time the issue occurred, my truck had only 47,000 miles. I brought it to Blasius Chevrolet in [XXX] on XXX, for diagnosis. The dealership determined that the Transmission Control Assembly (Part # XXX) had failed and needed to be replaced. I was informed that this repair was not covered under the powertrain warranty because Chevrolet considers the Transmission Control Assembly to be excluded from powertrain coverage, and my basic warranty had already expired. I was quoted more than $900 for parts and labor. Initially, I was told the replacement part would arrive within a few days. Later, the technician stated that other Chevrolet dealerships had the part in stock. However, after contacting those dealerships, he was told they would not release their inventory. Chevrolet then advised that the part was on national backorder, with the earliest estimated availability of XXX. As a result, I have been without my truck for approximately one month, creating a significant hardship. After researching this issue, I found numerous reports from other Chevrolet owners experiencing the same failure involving the Transmission Control Assembly. The apparent frequency of these failures, combined with the nationwide backorder of the part, suggests this may be a widespread defect rather than normal wear and tear. I believe Chevrolet should either: Cover this repair under the powertrain warranty, as it directly affects the operation of the transmission, or Issue a recall or warranty extension if this is determined to be a common defect affecting vehicle safety and reliability. I am submitting this complaint because I am concerned that a failure of the Transmission Control Assembly could impact the safe operation of the vehicle.

ELECTRICAL SYSTEM

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.
