general problems of the 2019 Chevrolet Silverado 1500 - part 2

86,000 miles on the vehicle and transmission and oil leakingproblem.

I was getting on the freeway and all of a sudden a lost power and heard a loud clunking noise. I drove as fast as I could to get in a safe area. Afterwards I had my vehicle towed to my mechanic. They said engine failure and possibly transmission failure. They found metal shavings in the oil. I had changed it myself a few weeks prior. I then took it to a gm dealer. I was just outside my powertrain warranty at about 70k miles. They said the same thing. 24k to repair. I had to junk the vehicle.

My truck out of nowhere will momentary lockup of the rear wheels, I can't get it to release unless I remove the battery. This has happened around a dozen times. It has happened a low speeds and high speeds. This is a safety issue and I can't drive my truck anymore out of fear I or someone will get killed!.

In 2024, I had the transmission replaced due it leaking transmission fluid. The transmission is sealed and there is no way to add fluid. This created an internal problem for the transmission. In January 2025, the engine made a loud pop noise and began performing horribly. My wife and I were on the interstate in a major city and surrounded by traffic. I drove it to the side of the interstate, immediately, and turned it off. I had to call someone to tow me back home(2 hours away) and my wife missed a very important doctor's appointment. Upon inspection, I found failed valve lifters, camshaft, pushrod and valve lifter tray. I managed to get everything replaced and the truck ran fine. March 2025, as I was driving on the highway, the truck stopped running. A message came on the dash screen saying, "shift to neutral and restart". I did and nothing happened. I had it towed to a shop. They told me it was a fuse block that was blown and the starter blew so they replaced them. It had struggled to start a couple of times and since I knew it had a new battery, a starter and fuse block made sense. I picked the truck up and in less than 24 hours, it happened again. It stopped running as I was driving and would not restart. The shop has checked gm tech forums and found where someone said to check if the motor would turn over manually. They have tried and failed. They, then, took the oil filter off and found metal shavings in the oil. Their diagnosis is that the engine bearing has seized and is causing the problems. My main issue is safety. My wife and I could have been seriously injured or killed and could have injured or killed someone else when the incident happened on the interstate. The same could've happened with just me in the vehicle or with our children. There were no warning lamps, messages or any symptoms whatsoever before January 2025 for the engine. The truck doesn't even have 100,000 miles on it and I have kept up all of the maintenance.

My truck is at hubler cevrolet in greenwood, in with engine oil cooler lines leaking at 40,000 miles. Gm customer satisfaction program for some VIN numbers expired in 2023 (n212326940). My VIN was identified as being ineligible. Upon my own further research these trucks are known to have issues with leaking or rupturing oil cooler lines leading to catastrophic engine failure. I suspect that the manufacturer of the previously covered lines is the same although the part application number may be different. The manufacturer produced a defective oil cooler line that is previously know to fail especially in cold climates. I am indianapolis, in where temperatures have been below 0 at times and is frequently below freezing during winter. My lines starting leaking after the first freeze, about 4 weeks ago. I closely monitored the oil level until I was able to take it to the dealer for further inspection, it always remained above half on the dipstick. I wrongly assumed that the leak was from an overtightened oil drain screw from the previous oil change. I had my oil changed at xpresspro a few days before I took my truck to the dealer because their technician identified the leak was from the oil cooler lines. The tech at xpresspro showed me a video he took on his personal cell phone showing the oil covering the engine oil cooler lines. The dealer is quoting 1400 for the repairs and they are not covered by powertrain warranty even though the engine would seize if they ruptured while driving. I reached out to gm customer service and spoke with kaylee she advised me to contact hubler to inquire about cost assistance and use my case number she gave for reference (xxx). I beleive this should be covered by a recall as it could have ruptured while driving causing the engine to lock and stop all forward momentum. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6.

Vehicle's cam shaft failed resulting in major engine damage and costly repairs, vehicle less than 100k miles, same issue as recent gm recall, but this was not included in recall.

See attached document for complaint.

Transmission slips going into 1st. Then when it shifts to the next gears it shudders. It is available for inspection but I have not taken it to a service center. No lamps and messages are present.

When I bought the truck it only had 82 miles on it. After owning it for about a month it was shifting very hard at times. So hard it felt like I was being hit from behind. I complained to the dealership and they told me "that's normal for those". I learned how to drive it to avoid the problem. At 52000 miles I had the dealership do the routine transmission service that is due @ 45,000. The truck was fine when I took it in. When I got it back it was shifting extremely hard and erratically. It would downshift and accelerate by itself. On wet roads it would fishtail and I would almost lose control. It did this in traffic and I almost slid into oncoming traffic. While pulling away from a stop sign, the transmission slipped so bad the engine revved to 5000 rpm before catching. Then the check engine light came on. I took the truck to the dealership the next morning and they checked it out. They said it needs a new transmission. They also said it was my fault for going past the recommended service interval by 14%. Now they say a new transmission is going to cost $12,582. 78. Gm has agreed to pay half of that but they have known about these transmissions for years and they kept selling them anyway. My truck was not showing any unusual signs that the transmission was failing until I got it back from the dealership after they serviced it.

There is an issue with the transmission. My vehicle had started shifting erratically and became very clunky. At highway speeds, my truck will shutter and shift up and down for no reason while remaining at a constant speed. I took it to a certified mechanic and I was told it is a matter of time before my transmission completely fails. I have an invoice confirming these claims. This is a very wide spread issue with these 8-speed transmissions. I was told by the mechanic that the 2020-2024 models of the exact same truck are now receiving recalls on the exact same transmission yet the 2019s are being overlooked.

They sold me a vehicle at the dealer. Three days after I bought it, I had to buy tires for it. Because they were in bad condition, they also charged me for a liquid called 3m nitro and I don't understand why they put it in if the tires were in bad condition, and they also promised to fix some details on the bumper and details on the paint on the body of the truck, and the transmission has already started to fail, and they don't want to help me or take responsibility. The truck still has a dealer warranty.

-the transmission on this vehicle has begun to shift erratically with an audible thumping or clunks at normal speed. At highway speeds the vehicle will shudder and shake as the transmission shifts through the gears and periodically upon reaching cruising speeds. - failure of the transmission is not out of the question. It could possibly lock up at any time while driving. - a reputable transmission service center reproduced and confirmed the complaint issues. - there have been no warning lights or messages pertaining to the issue. A vehicle diagnostic report confirmed no codes.

Transmission problems in 8l90. Needs valve body. Torque convert and few others. Lost communication with power steering control module. Most control to body CO trol module. Rear right and left speed sensor correlation.

Transmission jerks and bucks when shifting and when driving on high way it shakes so bad it messes with the steering wheel.

Transmission cooling lines leak,mileage 52363.

I own a 2019 Chevrolet Silverado 1500 lt trail boss that exhibits strange and persistent issues. A recurring engine code appears p0499, clears itself, and then reappears without consistent resolution. This affects the remote starter as the engine light will be engaged. Additionally, several service warnings flash momentarily and disappear, including: •service trailer brake system •brake system failure – top speed limited to 62 or 43 mph •parking sensor unavailable these warnings occur without warning and vanish too quickly to document fully. Despite multiple visits to the dealership, technicians have been unable to replicate or resolve the problem. This unpredictable behavior creates safety concerns, particularly regarding brake system reliability and sensor functionality. I and many others experiencing these same issues are concerned about a potential electrical or sensor issue impacting vehicle performance and safety.

Unknown, but I believe the torque converter gave out and messed up the transmission.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle briefly shuddered and lunged forward. The vehicle returned to normal functionality, but the failure became a regular failure. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the torque converter. The contact was also informed that the dealer observed metallic flakes inside the transmission fluid. The vehicle was repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 44,000.

Was driving and the engine died, lost power steering, lost gauges (no speedometer, no tachometer, gauges quite working at all) and lost power brakes. Had to try and pull over and was not able to stop or steer easily. I almost hit several other cars and a guardrail trying to stop and steer to emergency lane. After I got stopped, I was not able to restart my vehicle, the starter just kept running but the engine would not start and gauges didn't work. I had my vehicle towed home and started trying to figure out what happened. Put my code reader on the truck and it showed 12 different codes including ecm/bcm failure. I started checking fuses and relays but everything was good. Finally found the problem at the ecm. There was a wiring harness that was not secured and was rubbing against the frame of the truck. One little yellow wire had rubbed through and shorted out which killed the whole truck. It looks like the manufacturer didn't secure the wiring harness in several spots which allowed the wiring harness to rub on the frame and the mount that holds the ecm. The mount for the ecm has started to rub through a different wiring harness and had started rubbing through wires in that harness but I caught it in time.

Driving down road transmission felt like it locked the wheels and stopped the vehicle briefly. Vehicle went into limp mode. Almost got rear ended. Going 55 mph to immediate stop. Have been having transmission shifting hard with truck since purchase. When accelerating @low speeds and it vibrates. Every time it has been brought up to service department they say it was normal. Brought vehicle in 3 months prior to this incident for harsh shifting and vibration and dealership stated it was due to deteriorating fluid. They serviced transmission and filter. Once incident happened again took vehicle to dealership they ended up keeping vehicle for 58 days waiting on parts to replace the valve body and speed sensors.

The torque converter started vibrating and the transmission starting hard shifting its in shop now needing new torque converter and transmission.

I've replacd the transmission which was covered under extended warranty now I'm having to replace the engine which is not covered the car is only 5 yrs old.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle unexpectedly downshifted with the transmission overheating message displayed. The vehicle was able to restart however, the failure recurred. The vehicle was taken to an independent mechanic where the vehicle was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made not aware of the failure. The failure mileage was approximately 172,000.

When I started driving, the transmission began to feel loose, like gears weren’t seated all the way. And then it began revving for no reason, and would eventually catch a gear as I let off the gas. I was driving with my kids and I was afraid that the gears would catch at a high rev rate and send me forward into other vehicles or pedestrians so I needed to end my drive ASAP. I was attempting to turn left at a light and the truck stopped going into any gear and I was stopped in the middle of the road. I had to push my car out of the way with the help of others.

The engine oil cooler line detached from the crimp joints, causing an "oil pressure low turn vehicle off" alert. I was fortunately able to pull over immediately, and catch the 8 quarts of oil which dumped out. This resulted in $634 repair bill, and likely damage to the engine of the truck. Had I not been in a rural area and able to pull over immediately, I would have lost all power to drive and dumped that oil on the road, causing both safety hazard and environmental damage. This truck has been serviced by our local chevy dealer who confirmed the problem with gm. This is a known problem to gm, the subject of their customer satisfaction program bulletin n192220080, and a recall in canada and alaska. Clearly the issue exists in areas other than canada and alaska, yet gm refused to cover any of the cost under our 60,000 mile warranty and has not issued a recall in other states.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving 45 mph, the vehicle was vibrating abnormally and shifted out of gear independently. The vehicle was towed to the local dealer where it was diagnosed and determined that the engine needed to be replaced. The vehicle was then taken to an independent mechanic where it was diagnosed and determined that the torque converter was failing and needed to be replaced. The top of the engine was replaced, and the vehicle was repaired. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 112,500.

Vehicle has vibration at speeds of 40 and above. Vehicle shifts harshly and feels as if it’s constantly searching for a gear. You can feel transmission clunk when it shifts. Upshifts and downshifts at cruising speeds.

8l90 transmission failure at 60k miles.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? the transmission system appears to have malfunctioned, specifically causing hard, sudden jerks when shifting and sluggish acceleration. While the issue is ongoing, the dealer has not confirmed any problem. The dealer has performed transmission flushes twice under 60k miles and recommended a third flush a few months back when I took it in for the jerking issues. The transmission is available for inspection upon request. 2. How was your safety or the safety of others put at risk? the hard, sudden jerks when shifting can feel as if the vehicle has been rear-ended, potentially causing a loss of control or distraction while driving, posing a risk to both the driver and others on the road. Sluggish acceleration could also impair the vehicle’s response in critical driving situations, such as merging or avoiding obstacles. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? no, the problem has not been reproduced or confirmed by the dealer. The dealer claims the behavior is considered “normal operation,” despite the symptoms being severe enough to concern the owner. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the vehicle has only been inspected by the dealer, who did not find any issues with the transmission or other components. It has not been inspected by any other parties like the manufacturer, police, or insurance representatives. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? there were no specific warning lamps or messages associated with the issue. The symptoms of hard jerks when shifting and sluggish acceleration appeared over time but have not been linked to any warning signals from the vehicle’s systems.

Transmission shifts really hard and down shift hard. Have been the to dearships 3 times being told that’s just how the transmission is even them acknowledging. It’s a problem.

Transmission shudder and shakes at high speed and low speeds.

The oil cooler lines on my 2019 Silverado 1500 disconnected at the crimp while I was driving. The vehicle has only a bit more than 30,000 miles. I checked online, I. E. Various sites as well as NHTSA and found the gm customer satisfaction program n192220080. In the pdf on your site dated June 22, 2021, it is stated that only 530 vehicles were affected. I believe that this problem is more widespread than gm is willing to admit. Fortunately I was not driving on the interstate at a high rate of speed where “ a potential loss of propulsion” could have resulted in a tragic outcome.
