    The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at 30 MPH, the rear wheels locked upon depressing the brake pedal without warning. The contact temporarily lost control of the vehicle, and the rear wheels skidded, almost causing a crash. Due to the failure, the vehicle was towed to the residence, where it remained. The dealer was notified of the failure, and the contact was informed that there were no recalls related to the VIN. Upon investigation, the contact discovered NHTSA Campaign Number: 25V148000 (POWER TRAIN); however, upon contacting the dealer, the dealer claimed that there was no knowledge of the recall. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 136,000.

    Driving my truck and I suddenly got a warning on my dashboard that said, "Low Oil Pressure. Turn Engine Off." I pulled over immediately, shut off the the engine and called for a tow. Dealership called to let me know the engine was seized and would cost $22,270 to repair. Looking online I found that Chevy had released a Customer Service Program (CSP) detailing that the oil coolant lines in 2019 Silverado 1500 could have a weak / defective crimp holding the oil coolant line onto the connector and could separate causing catastrophic oil loss. It is also stated in the CSP that cold weather makes the issue more likely. I have tried getting GM to cover the repair since they knew about the issue and never contacted me to make the fix. GM is maintaining that they did nothing wrong and that my VIN is not listed as one of the vehicles in need of repair. This, despite the acknowledgement of the CSP and that the CSP "is for the dealerships." Which I pointed out the correction listed was for me to have the oil lines replaced and that never happened. I also pointed out as they said this wouldn't have been listined on my VIN because it was for dealerships and yet no one: not GM, not the dealership I bought the truck from, nor the dealership that regularly serviced my truck mentioned the oil line issue to me.

    I have a 2019 Chevrolet Silverado LT 1500 with only 19K Miles. When I brought this vehicle I was having problems with hearing a loud clunking noise coming from the rear of the Vehicle. Every Time I Stop at a red light, stop at a stop sign, yield at a yield sign, and slow down to turn in my driveway I can hear this clunking noise coming from the rear of the vehicle. If someone is riding in the backseat of the vehicle, they can feel the clunking noise every time I hit the brakes or slow down. After doing some research I honestly believe it’s the drive shaft that is on my vehicle that is causing this issue. Also, my vehicle does a hesitation when trying to accelerate on the gas pedal, which the drive shaft can cause this issue as well. There is a recall against this issue (Drive Shaft) but my Vin Number doesn’t call for a recall, I believe my vin number was missed in this recall. This is very dangerous because my Drive Shaft can drop beneath my vehicle while driving on the roads or highways and can cause my Truck to loose control and get into a serious accident or fatal accident. All I want is to have the Chevrolet Dealership to repair my Drive Shaft for free, because Chevrolet states that they will fixed all the drive shaft that is on recall on there time and the customer doesn’t have to pay anything. Please follow up on this serious matter. I don’t feel safe driving my truck anymore, so I keep it parked in my garage. PS : I took my truck in several times to three Chevrolet Dealership when I had full warranty’s and each Dealership told me that my truck is fine, I just have to drive it because it’s still new and this is not a problem at all.

    "Approximately four months ago, I noticed an oil leak coming from the midsection of the engine/transmission of my 2019 Chevy Silverado LTZ with the 6.2-liter engine. At the same time, I noticed a slight knocking or rattling noise coming from, I believe, the front of the engine. Upon taking it to the dealership, they replaced the engine oil coolant lines, only to find out that the engine was still leaking oil and still making the knocking and rattling noise. They then discovering that it was the rear main seal, they have since replaced it about one week ago. Yesterday, February 6th, about 12:15 pm in the afternoon, while I was getting off the I-405 in Renton Washington and merging onto the southbound lanes of 167. I was in the left lane and I made it about a quarter mile down 167 doing about 60 to 65 miles per hour and I lost power suddenly. As I started to merge into the right lane, I noticed the engine light came on, and then the truck seemed to kick down into first gear while I was doing 50 miles per hour, which instantly slowed it down. This forced me to cross over an on-ramp lane to get to the shoulder and come to a complete stop. After that, the truck would not start at all. I then had to sit on the side of the road for three and a half hours waiting for a tow truck to take me and my truck back to the dealership, which is also the same dealership where I bought the truck back in 2019. They have not diagnosed it yet as I just dropped it off at 4 pm on 2/5/2026. My truck has approximately 155,000 miles on it.

  12. Power train, Jan 22, 2026

    My 2019 vehicle experienced premature torque converter failure resulting in transmission shuddering, hesitation, and loss of power while driving. The transmission fluid was found to be burnt, and the vehicle requires major transmission repair. These symptoms occurred during normal driving conditions and created a safety concern due to unpredictable vehicle behavior, particularly during acceleration and merging. This issue is widely reported in 2019 vehicles equipped with GM 8-speed transmissions. GM has acknowledged the issue through technical service bulletins but has not issued a recall.

  13. Power train, Engine, Jan 15, 2026

    While driving the vehicle I began to hear a ticking noise in the engine (lifter tick) and the check engine light came on. The vehicle began to lose power and started shaking. I stopped the vehicle and turned it off and restarted it and began to drive as I was not far from home. I found that the vehicle did not have full power and was not firing on all cylinders. After getting the vehicle home a diagnostic code showed cylinder 2 was not firing. The vehicle was towed to the dealership who confirmed there was a bad lifter and roller that dug into the camshaft. The sudden loss of power and shaking of the vehicle while driving is the safety concern. It seems that this is a common problem with these engines that GM is aware of and has failed to address.

    I have a 2019 Chevrolet Silverado 1500 with the 5.3ltr V8. The vehicle has 44,500 miles and has zero accident history. On 01/12/2026, the oil cooler line broke while driving, leaving 8 qts of oil covering the underside of the vehicle (exhaust, suspension and tires) creating a fire hazard along with possible loss of control with the rear tires coated in oil. Additionally, the vehicle is undrivable almost immediately due to zero oil pressure. The local Chevrolet dealership diagnosed it as a oil line failure. There is a Chevrolet Customer service program N212326940 for only certain VIN for this vehicle for this specific problem, however it doesn't cover my vehicle. In reviewing different web forums, this is a commonly known failure point with some defect to the hose clamp. GM has not extended a recall and has stopped covering this known failure. I'm not sure if it's a vendor/supplier failure with the oil line or an installation problem. A full recall and/or 10yr/100k warranty coverage should be provided for all oil line failures due to thousands of prior similar failures with the same oil line.

    The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle remained stuck in 3rd and in 4th gears upon depressing the accelerator pedal. Additionally, the vehicle contact stated that the vehicle experienced a hard shift while driving. The contact stopped, parked, and turned off the vehicle for 10 minutes; however, the failure recurred while driving. The vehicle was taken to a dealer, where the failure could not be replicated. The contact was informed that the vehicle was operating as designed. The manufacturer was notified of the failure. The failure mileage was 3,900.

    Component or system failure: The engine valvetrain (camshaft and lifters) sustained severe internal damage, including camshaft scouring, confirmed during inspection and teardown by an authorized Chevrolet dealership. In addition, the rear differential was found to contain no gear oil when the fill plug was removed during inspection. The vehicle and components are currently at a Chevrolet service center and are available for inspection upon request. Safety risk: The vehicle experienced persistent drivetrain vibration and abnormal operation that worsened over time and ultimately rendered the vehicle non-operable. Internal engine damage and a rear differential without lubrication present a risk of sudden drivetrain failure, loss of propulsion, or loss of vehicle control, particularly at highway speeds. The vehicle is currently unsafe to operate. Problem confirmed: Yes. Engine damage has been confirmed by the dealership during teardown. The absence of gear oil in the rear differential was directly observed during inspection. Inspections by others: Yes. The vehicle has been inspected by an authorized Chevrolet dealership and by third-party inspectors associated with the extended drivetrain warranty administrator. Two inspections have been completed, and a third inspection has been ordered. No repairs have been completed as of this report. Warning lamps or prior symptoms: Beginning around approximately 21,000 miles (2022), the vehicle developed drivetrain vibration. The vehicle was taken to a Chevrolet dealership at that time, but the cause was not identified or corrected. No warning lamps or messages are recalled.

    The vehicle was shifting hard and eratically on the highway. All dashboard lights came on including the ESC failure warning. A misfire in cylinder 2 occurred without any warning lights causing the vehicle engine to stop running on a highway. The mechanic repair shop did a disgnostic evaluation and reported a catastrophic engine failure from cylinder 2. The engine does not run and requires full replacement. The vehicle has only 80,000 miles.

    Purchased Truck in 2019 - 2 weeks after purchase the truck gave a Code and started to stall while in motion. We took into dealership and they did a complete review. They discovered and documented the following: Removed transmission fluid pump and disassembled to inspect- found a large piece of manufacturing metal flashing - that got stuck in valve bore preventing full movement etc. we kept up on all of our maintenance oil changes. We had the transmission flushed just near the end of the warranty as they recommended it. Shortly after, we started experiencing the same issue. Per the dealership, no recalls for this. The power would completely shut down while driving. Took to dealerships , now telling us we need new transmission $12,000 and is the reason for the power shutting down. They are saying GM will offer us $2,000. We feel this is all due to the flushing and maybe having particles from the flushing,

    My 2019 Chevrolet Silverado 1500 with the 5.3L engine developed a severe tick, misfire, and rough idle at only 93,000 miles. This was diagnosed as a collapsed AFM lifter on Cylinder 2. GM 5.3L AFM lifter failure is extremely common in these trucks and causes sudden loss of power, misfires, and unsafe driving conditions. This is a known widespread defect, yet GM has not issued a recall. The failure happened without warning and required major engine disassembly. This should be investigated as a safety and reliability issue.

    The 8-speed transmission has been a problem from day 1 of owning this truck. It has a bad vibration, slips into gear and hard shifts. I have maintained this truck to the fullest and have done all service to the fluids as requested by the manufacturer. I have never pulled a trailer, and I want The NTHSA to make all Chevrolet products that have this 8-speed transmission recalled. GM should make this right. These vehicles aren't cheap.

    The transmission consistently fails to shift properly, hanging between Drive and Overdrive. The dealership initially diagnosed the issue as a faulty torque converter & lines, then a tow/haul switch, and replaced it; however, the failure persists. The transmission now requires full replacement. I believe this is a known manufacturing defect present prior to the vehicle's release. Additionally, the lifetime powertrain warranty originally attached to the vehicle has been removed from GM's records. This hesitation causes unpredictable acceleration and loss of power, creating a significant safety hazard when merging onto highways or navigating heavy traffic. It is available for inspection upon request.

    During the first transfer case fluid service on a 2019 light-duty 4WD truck equipped with an Autotrac two-speed transfer case, the drained fluid was bright red and consistent with automatic transmission fluid rather than the required GM Auto-Trak II blue/green fluid. The transfer case had never been serviced since new, so the fluid appeared to be the original factory fill. Before the discovery, the vehicle occasionally hesitated when shifting between drive modes and sometimes felt as if the system was binding or briefly locking up during transitions between 2WD, Auto, and 4WD modes. These symptoms were intermittent and no warning lights appeared. Using the wrong fluid in this type of transfer case can affect clutch-pack operation and may cause premature wear or loss of proper torque transfer. The system has now been refilled with the correct fluid, and the drained fluid is available for inspection. The issue has not yet been inspected or confirmed by a dealer.
