NHTSA investigations into the 2019 Chevrolet Silverado 1500

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

While flat towing my pickup truck behind my motorhome, on interstate 94 eastbound, in Minnesota I noticed smoke on my screen in the motorhome back facing camera. I safety pulled over to a truck rest area in Avon Minnesota. I went to investigate and realized that the pickup truck had flames coming from underneath the hood. Because of the fire and heat I wasn’t able to release the pickup truck from the motorhome which ultimately caused the Motorhome to catch fire as well. Police and fire department were called and both the Motorhome and pickup truck were totaled. My insurance company has possession of both vehicles. I previously had electrical problems with the pickup truck and took it to the Chevy dealership to address the issue. Evidence of module overheating with traces of burn were found on one occasion. I’m uploading photos of the police report and work orders from the dealership. No one was injured but all of our belongings were destroyed or damaged from the fire. We were left with nothing but what we had on at the time.

SEAT BELTS

On January 28, 2023, my Chevrolet Silverado was involved in a significant multi-impact collision. At the time of the accident, I was a front-seat passenger and my vehicle was fully stopped when it was struck from behind at high speed by a Dodge 2500. The force of the rear impact pushed my truck into the vehicle in front of us, resulting in a secondary front-end collision. This sequence occurred twice. During the collision, the front passenger-side airbag did not deploy, and the front passenger seatbelt failed to lock. As a result, I was thrown violently within the passenger side of the vehicle and struck my head on the dashboard. In contrast, the driver’s seatbelt locked properly, as did the rear seatbelt where my child was seated. Due to the failure of the passenger-side seatbelt to lock, I sustained a severe concussion, a black eye, and other injuries. The vehicle was subsequently inspected by my insurance company. When sheriff’s deputies and state police arrived at the scene, they expressed concern and surprise that the passenger seatbelt did not lock and that no airbags deployed despite the severity of the collision. Shortly after the accident, I contacted GMC regarding these safety concerns. GMC retrieved the vehicle’s Crash Data Recorder (CDR) and conducted an investigation. I was later informed that GMC found no defects or issues with their products. Nearly three years have passed since the accident, and I remain deeply concerned and dissatisfied with GMC’s conclusion. The passenger-side seatbelt did not function as designed, while the driver and rear seatbelts did, and no airbags deployed. I do not believe adequate accountability or explanation was provided regarding the apparent failure of the passenger-side restraint system. Given the force of the impact, I could have been ejected through the windshield.

I was driving my 2019 Chevy Silverado TrailBoss with 81,000 miles at 65MPH on I-80 East in Omaha, NE, when 3 warning lights came on. The first was the Service Parking Brake. The second was Service ESC. The final was a flashing Check Engine light. My truck started backfiring/misfiring, making a loud ticking noise, and running extremely rough. I was trying to merge off the interstate, but it was running so rough that it made it very difficult to do so safely. Eventually, I just had to finish going where I was headed and park it in the lot. I did some research and called my local shop. They said to stop driving immediately and have it towed to them for inspection. They used a diagnostic tool and diagnosed the issue as a DFM lifter failure. But they could not fix it there and recommended I take it to a different shop. I had it towed again, and they did their own diagnostics and have the same idea, but without taking the engine completely apart, they can't tell for sure. They want to charge me $1,250.00 to inspect it further. I called the dealer where I purchased the truck back in 2019 and am working with them on next steps. The last shop quoted me $7,800 repair if it is indeed the DFM lifters. Based on what I know, this is a known issue with these trucks. GM has an "Out of Warranty Policy Assistance" in place just for these know lifter issues. This is very concerning that GM hasn't done a recall on these parts as it has shown to be a safety issue when driving the vehicle in traffic on the interstate. I just hope that GM assists me with the repair costs because it is not guaranteed and I cannot afford $7,800 right now.

I am reporting a potential safety defect involving my 2019 Chevrolet Silverado 1500 Z71 Trail Boss (VIN [XXX]), currently at approximately 63,000 miles. My truck suddenly developed a rough idle, engine ticking, and a cylinder 3 misfire. The check engine, traction control, parking brake, and “Service ESC” warnings appeared. The transmission also began shifting extremely hard, at times feeling as though another vehicle had struck the truck from behind. The oil pressure gauge also stopped functioning. Due to these symptoms, I stopped driving the vehicle. A diagnostic scan produced P0303, P0449, P0498, P0499 and P0500. After replacing a failed cylinder 3 spark plug, the truck initially ran perfectly for approximately 20 minutes before the rough idle and warning lights returned. The vehicle was subsequently diagnosed by a Chevrolet dealership. The dealership determined that the engine suffered a collapsed lifter that damaged the camshaft and other internal engine components. The engine repair estimate is approximately $10,000–$12,000. The dealership has also reported that the transmission is slipping and believes the torque converter/transmission requires approximately another $6,300 in repairs. I am concerned that a lifter/DFM-related failure causing a misfire, rough running and potential loss of engine power could occur while a vehicle is traveling at highway speed and create a significant safety hazard. The severe transmission shifting and subsequent slipping are also concerning because unexpected vehicle behavior during acceleration or while in traffic could increase the risk of a crash. The truck has been regularly maintained and has relatively low mileage for its age. I am requesting that NHTSA review whether similar engine/lifter/DFM and related powertrain failures represent a broader safety defect and whether an investigation or recall is warranted.

Third transmission failure in 10 months on this vehicle (8-speed automatic). (1) Oct 2025, 67,885 miles: transmission shuddering; dealer replaced the complete transmission with a GM remanufactured unit under extended warranty (RO 240481, Nucar Lannan Chevrolet of Woburn, MA). (2) Jul 2026, 82,439 miles: vehicle would not shift on the highway while driving; DTC P2824 stored; dealer replaced the transmission valve body under warranty (RO 248929). (3) Aug 3, 2026, approx. 82,500 miles — three days after the valve body repair was returned to me — the transmission locked up and the vehicle would not shift gears while in traffic. Loss of gear engagement while driving creates risk of a crash from sudden loss of propulsion. Vehicle is back at the dealership now for the third repair. This vehicle's 8-speed transmission (8L90/8L45 family) is the subject of known shudder/valve-body defect litigation covering 2015–2019 Silverado models.

At 70,000 miles the engine failed. Dealership said it was due to the current issues with the 6.2 motors but mine was not included in the recall but was being evaluated to be part of the recall so I did have to buy a new engine.

POWER TRAIN

What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission and drivetrain system appear to be defective. The vehicle repeatedly experiences hard shifting, transmission shudder, hesitation during acceleration, delayed engagement when shifting into gear, and erratic gear changes. These problems occur during normal driving and have progressively worsened over time. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The transmission hesitation and delayed acceleration create a serious safety hazard. When pulling into traffic, crossing intersections, or changing lanes, the vehicle does not respond immediately when the accelerator is pressed. The delay leaves the vehicle exposed to oncoming traffic and increases the risk of a collision. The hard shifting and shuddering also cause the vehicle to behave unpredictably, reducing driver confidence and making it unsafe to operate in normal traffic conditions. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem is consistently reproducible during everyday driving. The transmission shudders, hesitates, and shifts harshly on a regular basis. Although the condition is intermittent in severity, it occurs frequently enough to create ongoing safety concerns. At this time, the vehicle has not been inspected by police or insurance representatives. The vehicle remains available for inspection. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? The first symptoms were occasional hard shifts and slight hesitation during acceleration. Over time, the condition worsened, progressing to severe shuddering, delayed acceleration, and increasingly harsh gear changes. No warning lights or diagnostic messages appeared when the symptoms first began, making it difficult to identify the problem before it be

I was driving the vehicle and suddenly there was a loss of power and a ticking noise. I was up to date with my oil changes per dealer recommendations. Had the vehicle towed to to Chevy dealer and they said they weren’t able to find what the problem is without further diagnosing. Further diagnosing was estimated to be about $2500. I had it towed to an independent shop, Viking Motorsports, to which the owner/mechanic tore down the engine and deemed it as bearing failure in my 6.2 L87. There was no warning whatsoever, just went from running to engine dead immediately. I proceeded to an engine change that has costed me approximately $15,000 and would like full reimbursement if not partial reimbursement from GM given that this is a known issue for the problem. I did not go with the Chevy Dealership for the job since they quoted me $20,000+ for the engine swap and realistically that wouldn’t make financial sense. I have a High Country and at 102,000 miles when the engine has failed. This has put me in such a financial bind.

Wife was driving on the interstate when the vehicle revved up and then a loss of power. had to drive home while vehicle was popping and still loss of power. I took to an Independent Service Center, and they started a tune up with changing plugs. They checked vehicle and advised that it was possibly a lifter failure, but they couldn't fix it. I took to another independent service person and after a diagnostic check and looking into the engine it was confirmed it was a lifter issue. Vehicle has been in the shop for 3 weeks waiting on parts.

I have a 2019 Chevy high country that went into engine failure when going down the freeway to work. The engine light came on flashing and the engine was stuttering. I had it taken into the local Dealership where they first replaced catalytic converter. 3 months later I had engine failure again going down the freeway. I had them drop a whole new engine into it. I understand there is an investigation regarding a recall for 2019-2020 year vehicles. How I got the vehicle: I had previously bought a certified used Chevy Silverado 2016. It also had engine failure where it would shut off in the middle of driving. I repeatedly took it back to the dealership (different dealership) and they could not fix it; Instead had me test out another loaner vehicle for possible purchase. Driving off of the lot that loaner vehicle engine light came on. I took it back and they failed to mention to me that they dropped a new block into that one. After that I got another loaner vehicle that I was pigeonholed into purchasing as they could not figure out the issue with my previous purchase. 6 months later it started having electrical problems with rear cameras not working, sensors out, etc; Then eventually the engine failed. The amount of money I have spent and growing safety concerns I have for transporting my family and myself are beginning to grow. I do not want to incur subsequent mechanical failures/expenses in other areas due to previous engine failure.

STEERING

I had a complete loss of steering and had to have the truck towed to the dealership. This could have caused a very serious accident. There was no previous warning - it just went out. The dealership charged me $2183 to replace the steering gear. According to the literature, the steering function should last to well past 100K miles (my truck had 66,552 miles on it). In addition, there are multiple reports of steering going out online - perhaps a recall is in order. The literature also states that if diagnostic code C1599 then the steering rack is completely fine mechanically but it has simply lost its electrical connection. That is the code that the dealership saw - it sounds like the fix could have been much simpler and cheaper.
