2023 Chevrolet Silverado 1500 Owner Complaints

I drive a 2023 Chevrolet Silverado 1500 3.0L Diesel with the 10-speed transmission. The transmission control software failed to monitor/detect valve body wear or trigger a 5th-gear 'limp mode' safety net, resulting in three separate instances of sudden rear-wheel lockup at speed. The dealer was unable to replicate the issue during a service visit from 6/10 - XXX. The issue was raised as the transmission was shifting increasingly badly leading up to this service visit. The first full lockup occurred a few days after receipt of the vehicle on XXX driving eastbound on [XXX]. Off the gas, coasting downhill. Once everybody started speeding up, I increased the throttle gently and the truck shook violently. I initially thought I had been hit by another vehicle but realized it was the transmission. Speed was noted 24 mph. The second incident occurred XXX while traveling to [XXX]. Driving southbound between [XXX] and [XXX] at approximately 50 MPH in a coasting condition. Went to pass a slow vehicle and the vehicle jerked violently an locked the rear wheels. Initial assumption was that I had been hit. Was able to regain control and continue. The third incident occurredXXX while traveling from [XXX] to [XXX]. Driving eastbound on [XXX] at approximately 35 mph, when moving from a coast to acceleration posture, the vehicle again locked the rear wheels and jerked violently. Finally, onXXX when traveling southbound from [XXX] to [XXX], I stopped for fuel. When attempting to accelerate onto the freeway, the vehicle failed to engage 6 gear, stumbled, and then went into limp mode with a check engine light. On XXX a [XXX] dealer found code P0747 and addressed the issue with [XXX]. I was forced to rent a car to continue my journey to [XXX]. GM ultimately shipped my truck back to me one week later. The software 'fix' clearly did not work as intended and remains a serious safety hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact's daughter owns a 2023 Chevrolet Silverado 1500. While the contact's daughter was driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with a failed evaporative emission purge pump. The contact was advised to take the vehicle to the dealer. The dealer was contacted by phone and made aware of the failure. The vehicle was taken to the dealer where the failure was confirmed. The contact was informed that the repair was covered under an unknown recall. The contact was later informed that the repair was not covered under the unknown recall. The contact referenced an unknown recall; however, the VIN was not associated with a recall. The vehicle was taken back to an independent mechanic and the vehicle was repaired. The manufacturer was contacted by phone and made aware of the failure. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 58,010.

Evaporative emissions purge pump failed at 18,473 miles. As the bumper-to-bumper warranty has expired GM refused to cover this repair. As this is a known problem with certain GM vehicles, the repair is covered for older model year out-of-warranty cars and for residents of other states (California, for example). This repair is covered by the emissions warranty in some states (California), but not Michigan.

While driving at Interstate speeds, the engine abruptly stalled, causing an immediate loss of motive power. I was able to coast off the Interstate to a surface street then into a gas station parking lot. Once stopped, the engine would not start again. It would crank repeatedly but never fire, like it was out of gas, but I had nearly 1/2 tank still. This is a safety concern having a 3yr old truck just die on you at highway speeds. This vehicle matches the exact year, make, and model of the expanded GM Emission Recall Campaign N262558690-01 (NHTSA ID 11037321) for Fuel Pump Power Control Module failures, but the VIN is currently excluded."

This truck and hundreds, if not thousands of others has many issues with the electronic shifter. Not only do they frequently fail, but Chevrolet does not have any parts available to the dealerships for weeks. These Duramax 3.0 diesel engines are also a huge problem with the emission system and DEF. They constantly fail and we are spending thousands to repair. My truck is stuck at a dealership in [XXX]. I had to rent a vehicle to drive back home to [XXX]. The dealer has no idea how long it will take to get a shifter from Chevy. Is there any help available. Why aren't these shifters under a major recall? I am literally stranded after paying $65,000 for a truck! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving my 2023 silverado 1500 down the highway when my engine started loosing power and then shut completely down at 65 mph. My safety and others were at risk due to speed and loss of power. I was lucky enough to not be on an interstate or in a metropolitan area. This happened due to a recall on this particular motor from General Motors (6.2 Liter). My vehicle was taken to a local General Motors dealership and the engine replaced. There were no warnings or abnormal behaviors of the vehicle prior to and the vehicle was taken in for the recall prior to the incident. The motor oil was changed to the recommended 0-W40 by the dealership.

On our way to [XXX], we heard a clacking noise coming from our engine. Pulled off the highway and had it towed to Reeder Chevrolet. It was Sunday XXX. On XXX we went to the dealer and they said we spun a connecting rod bearing and needed a new engine. Truck is a 2023 Slverado, 5,3 engine, with about 65000 miles on it. 5000 miles out of warranty. It took 18 days, and cost $12,214.37 to replace. Dealer stated that if I wanted to pursue a warranty claim, we would have tpo pay for them to disassemble the engine, diagnose the problem, then reassemble the engine, and they would send it to GM. GM would decide if it would be covered under warranty. If not, we would be out the cost of the diagnosis. I have always used 0W-20 full synthetic oil when an oil change was required. After searching this problem online, I found a tech service bulletin changing the requirement to 0W-40. We were never notified of the change, and the 2026 owners still say to use 0W-20. Attached are the invoice and recommendation to replace engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have noticed a ticking noise that is coming from the engine, driver side, the tick after the recall was preformed, 5-23-2025. The tick has grown in loudness from that date. Took the truck to the dealership and they did a check but was unable to locate anything, no parts were removed and no witness marks on any of the engine areas Example oil pan and so on. I was told that they would charge me if the truck was brought back for the same issue per GM not the dealership. They have been doing my oil changes at a 3,000 mile interval. The tick has gotten progressively louder, and I am nervous about driving my truck but I can't not work.

The engine in my 2023 Silverado ZR2 (6.2L L87 V8) failed. It is available for inspection at Rick Hendrick Chevrolet ([XXX]). On XXX at about 67,000 miles, and the days leading up to it, the truck repeatedly struggled to start due to metal on metal contact, almost leaving me and my family stranded multiple times. Driving the vehicle produced a loud rattling noise at 2200 to 2700 rpm, and felt unsafe to drive. Especially with my family. The problem was reproduced and confirmed to be an engine failure by the Rick Hendrick Chevy dealership a week after being dropped off with an appointment. I have been told the engine needs to be replaced under the special coverage program (N252494003). The L87 recall inspection and oil change was completed on XXX also by Rick Hendrick Chevy. There were not warning lights or other symptoms leading up to this engine failure. The symptoms of struggling to start and the ticking noise as 2200 to 2700 RPM started that weekend before I brought to dealership. They got progressively worse. Dealership has said I will receive a new engine under warranty but no timeline for completion. Additionally I have not been furnished with a service loaner or option for one. Leaving me with no vehicle to replace it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine failed and was replaced at 38k. Transmission shudders, have been back to dealership multiple times for transmission shudder, have been told it was tires, torque converter, and valve body. When those items didn’t fix the issue, I was told it was the engine dfm and that it was normal and not a problem, AFTER they had already acknowledged the transmission issue by trying to fix it with a torque converter and valve body. Engine failed again at 54,604 miles while at high way speeds in rush hour like traffic in between [XXX] and [XXX], while pulling a camper. Truck oiled down the interstate and produced a blueish/milky looking cloud that caused drivers behind me to lock up their brakes because of bad vision, creating a hazard. I was told by gm that they wouldn’t tow the camper that I had to take care of that but they wouldn’t tow send a truck for my truck. Tow truck gets there and says my truck is too big and leaves. I called my own rollback to get my truck 3 1/2 hours later and they came and got it. Was stranded on the side of the interstate for 4 1/2 hours in 90 degree weather, to my knowledge the 2nd truck gm was supposed to send never showed up. Requested a buyback and was denied with no reason given. I have a lot of records if anyone wants them.

Catastrophic Engine failure - Chevy, Silverado 1500, Yr: 2023; Odometer: 33,183: On 8/16/2026 we were traveling down a busy highway towing our camper and the engine completely stopped, no propulsion, no warning lights, no check engine lights; complete failure; we had to coast to side of road. The only thing that indicated a problem is that we started hearing what sounded like marbles rattling, it wasn't loud but noticeable. We pulled over at gas station to check oil, even though we just had the oil changed for maintenance on 7/17/2026 (Odometer: 32,587). Everything checked out ok; however, the marble sound became louder; then within 5 minutes of leaving the gas station, we lost all engine propulsion; the engine completely shut down. Our safety was put at risk as we had no truck engine and were towing a camper on a busy highway; and had to try and coast to a safe location on side of road; miles away from home. We had to call a tow truck to come get us and unfortunately, they could not help us with our camper so then had to call our son to come with his truck to get our camper and us home safely. The tow company also had a difficult time getting the truck into neutral to tow. The truck was towed to our hometown Chevy Dealer. The dealer said that they were not going to diagnose the problem and instead are ordering a new 6.2 engine; same as the 6.2 that failed. We asked if this would fix the problem and they said there were no guarantees as it is the same engine with the same problem. Prior to this event, we received a recall in Sep 2025 and an engine inspection and oil change was performed on 9/12/2025 (Odometer: 25,751); we were told that our engine was ok. As of 9/3/2026; we have been without our vehicle for 17 days.

My Second motor blew up while towing my camper with my entire family in the vehicle, leaving us stranded 1 foot from interstate traffic for over an hour as we waited for a tow truck—this was GM's 3rd attempt to fix the problem. There were no warning signs. The motor had roughly 4 thousand miles on it. I have since gotten rid of this truck (and suffered financial loss) before it gets me or someone else killed. GM needs to fix this. o30,317 miles – Started using Heavier oil 6/18/2025 o36,732 miles – Recall “fix” 11/10/2025 o38,917 miles – 1st Engine Failed 1/9/2026 oTruck returned to me – 1-24-26 o43617 miles – 06/20/2026 Replacement motor blew up I can't remember the exact speed, but I was going with the flow of traffic, so I'm going to guess it was 70-75. The file CTCS654636 is the second motor failure. Starr RO 626023.pdf is the first engine failure. and i have also uploaded the two files of when i swapped oil and had the recall fixed.

Description of the Problem: My 2023 Chevrolet Silverado 1500 has a recurring transmission issue involving hard shifting and shuddering during normal driving. The transmission frequently hesitates, clunks, or jolts when changing gears, especially at low to moderate speeds. These symptoms occur consistently and have worsened over time. Safety Concerns: The harsh gear engagement and shuddering make the vehicle difficult to control smoothly. It feels like something will break while I'm driving. The unpredictable shifting behavior feels unsafe in traffic, during merging, and when accelerating from a stop, or driving on the freeway. I am concerned this may be related to widespread transmission complaints reported by other 2023 Silverado owners, including valve body and TCM failures. Service History: I have not contacted my dealership regarding the issue. Why I’m Reporting: I believe this transmission behavior presents a potential safety defect. I am submitting this complaint so NHTSA can review it as part of ongoing monitoring of similar issues reported for this model year.

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.

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.
