general problems of the 2019 Chevrolet Silverado 1500 - part 1

Engine oil cooler line leaks and crimping does not hold hose tight enough and slipped off crimp fitting. Line came completely off of crimp fitting and leaked all engine oil. Forced engine to be turned off and low engine oil marked on dash.

"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.

Afm lifters has failed in my vehicle 3 times as of date. Being that its a costly repair this should be recalled. Information provided is the latest mileage.

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.

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.

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.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the transmission failed to shift properly and the vehicle failed to accelerate above 43 mph, with several unknown warning lights illuminated. The contact stated that the brake pedal became inoperable and required several pumps before the vehicle was able to stop. The contact stated that onstar service was contacted and initially provided several error codes on the vehicle. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired. The dealer was not contacted. The contact later contacted onstar service again to obtain the error codes and was informed that no error codes were present, and none were provided. The manufacturer was made aware of the failure and referred the contact to the NHTSA hotline for further assistance. The approximate failure mileage was 43,000.

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.

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.

Transmission failed while in drive and going up a hill.

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.

When driving normal speeds to work on a county road, engine light comes on, service light comes on. There was a tapping noise and reduced power. Luckily, there was a sports field parking lot that I could pull into to get out of traffic. We had the truck towed to our house through our roadside assistance program so that we could determine what to do. If we had not been able to pull off the road as quickly as we did, we probably would have been hit by the semi that was barreling behind us. The truck had reduced power.

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,.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving 40 mph, the vehicle jerked and vibrated abnormally. In addition, the rpms fluctuated, and there was an abnormal sound coming from the transmission. No warning lights were illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact stated that the failure persisted. The manufacturer was made aware of the failure and advised the contact to report the failure to the NHTSA hotline. The failure mileage was approximately 85,000.

I have had to put my vehicle in the shop for transmission repair. The first time it was in the shop for over a month to only get it back and have the same issue. Now the shop is telling me that gm is having a system glitch and they are unable to program it.

Truck lost power and began to shake while on the interstate traveling at 75 mph. The check engine light came on. The screen also displayed a message to service the esc system and the parking brake system. The truck has been maintained at the recommended service intervals. The dealership said the lifters needed to be replaced as well as the electronic brake control module. With a cost of over $8000. The truck has 108,000 miles on it.

Leaking oil cooler lines that had a customer satisfaction campaign but it’s over and now they are leaking.

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 transmission will down shift on the freeway losing power causing a safety hazard, engine rpm's start taching out & will not shift leaving you in traffic trying to avoid a collision.

Reduced engine power message pops up while driving check engine light stays on codes that came up for Cadillac converter and transmission failure.

The 6. 2 eco tech v8 is failing. Chevrolet new car of lowell massachusetts reports that motor needs to be torn down due to component failure. Also transmission is whining and will need replacement transmission shifts hard between gears and lunges forward while down shifting.

1. Engine/transmission 2. While driving and acceleration vehicle stalls/hard shifts. The truck was running just fine one day then the next day upon starting the truck, vehicle warnings for "service" parking brake system and ecs started showing up and the truck started running rough, smoking exhaust, smelling, and the air conditioner went out. All at the time/day. 3. An independent service center provided a diagnosis that stated the "motor was shot" oil was getting passed the rings/seals and entering cylinder 6.

Transmission is shifting and shaking and vibration funny whines when driving and hard shifts makes clunking noises when shifting or down shifting. Engine ticks very loud and loses power.

I have been hearing noise coming from the rear of the engine or front of the transmission. I took it to my local shop and they said it appears to be coming from the transmission and that I should take it to a Chevrolet shop because their is a service bulletin (pip5996a) that describe what I am experiencing. They gave me a copy of the service bulletin and it covers many models and years of the silverado. I called to make an appointment with chevy and they said my silverado is not associated with any recall, so this service bulletin does not apply. I don't understand how it does not apply when my make and year is listed on the service bulletin.

Passenger side lifters have failed, along with camshaft. The induced misfire caused a sudden and potentially unsafe jerking of the vehicle while on the expressway. The vehicle was on cruise control and running at 1,400rpms at the time of the failure. There were zero warning lights or vibrations/noises that could have indicated an imminent failure. Thankfully I was alone on the expressway at the time of the incident as the vehicle started bucking, jerking me out of my lane until I could regain control. Vehicle had 105,500 miles with all engine maintenance up to date prior to incident. Speed limit on this section of us31 is 75mph.

The valve body for the transmission failed. While driving the vehicle transmission would shift violently. This would cause the truck to jerk forward a few times before engaging the next gear. At times it caused a slowed performance and could have caused an accident with another motor vehicle especially when traveling uphill. I brought the truck to a Chevrolet dealership and they confirmed this issue. I also completed online forum and general searches through google which confirm this is an issue especially with the 4 cylinder and v6 engines. The check engine light came on when the issue first occurred. The issue happened a week after my catalytic converter was replaced under warranty in July 2025.

Took it to chevy dealer for oil cooler lines to be replaced I have been in touch with gm since my truck wasn’t under any open recalls to try to get some of the money back for the oil cooler lines since gm has had a big problem with them losing oil.

Vehicle transmission harsh shift and failed to shift gears. Feels as though I’m pushed forward when accelerating. Harsh clunk coming from the transmission. Transmission flush done at the dealer. Was told transmission needed a new valve body, part was on backorder and there were 25 similar trucks ahead and waiting. Several transmission related codes have also come up. 58000 miles.

During acceleration my vehicle had a whinning noise coming from near the transmission. It will buck and then when slowing down to a stop it bucks like being hit in the rear by another vehicle. It also shudders and makes the reduce engine power light come on.

Was driving on the highway, heard loud bang followed by a violent metal-on-metal slapping or knocking sound, and a sudden loss of engine power. Came to find it was crankshaft/connecting rod issue that is common in these vehicles. Have a picture of the broken rod and am waiting the get it repaired.

What component or system failed or malfunctioned, and is it available for inspection upon request? the ecu/power train failed/ yes the vehicle is available for inspection. The vehicle's check engine light & traction light came on & the dash displayed multiple warning messages including reduced engine power & service ecs. How was your safety or the safety of others put at risk? I was traveling on the interstate at 65 mph in traffic in the far left passing lane. Engine power was reduced & I had to safely navigate the vehicle through traffic & multiple lanes to safely get the vehicle to the shoulder of the interstate & avoid causing any accidents. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the problem was confirmed by my local Chevrolet dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? it was inspected by my local Chevrolet dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no there was not. The issue was attributed to a known manufacturing flaw on my vehicle. The wiring harness to the ecu was chaffed caused by rubbing on the frame, ecu bracket and/or a arm which in turn caused the issue. Gm published a repair bulletin on this issue as well as the NHTSA.

See attached document for complaint.

Gm says my VIN was not part of the recalls, the VIN wasn't the problem,it was the transmission!!! letter I sent to gm : transmission failure on 2019 Chevrolet Silverado 1500 lt dear general motors customer assistance, I am writing to formally express my concern regarding the complete failure of the 8l90 transmission in my 2019 Chevrolet Silverado 1500 lt. I have been a loyal Chevrolet customer and have always trusted gm vehicles for their reliability and performance. However, the recent catastrophic failure of my transmission—resulting in both internal and external damage—has left me extremely disappointed and financially burdened. This vehicle, equipped with the 8-speed 8l90 transmission, began exhibiting harsh shifting, delayed acceleration, and shuddering well before the failure. Despite regular maintenance and proper care, the transmission ultimately failed and "blew up" both internally and externally, rendering the vehicle undrivable and in need of complete transmission replacement. Upon further research, I discovered that numerous owners of 2015–2019 gm vehicles with the 8l90 transmission have reported similar issues, and multiple class-action lawsuits have been filed citing systemic defects in this transmission design. Though no recall has been officially issued, the volume of complaints and the existence of internal technical service bulletins (such as TSB 16-na-019) suggest gm is aware of the ongoing problems associated with this transmission. Given these circumstances, I am requesting that general motors stand behind its product and assist with the full cost of replacing the failed transmission. I am prepared to provide documentation including service records, a technician’s report on the failure, and photos of the damage if needed. Please let me know how gm intends to proceed with this request. I would appreciate a prompt and fair resolution to this matter. Sincerely, [xxx] VIN # [xxx] current mileage: 114850 information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 55.

Since I have owned this vehicle I have experienced erratic shifting, primarily when driving in traffic, and when the vehicle is downshifting to 1st or 2nd gear. It has occasionally occurred when traveling on the highway during an upshift, but this is rare. I have also experienced lurching when stopped, or creeping forward in anticipation of a turn. I can occur at any time, and under any type of conditions, hot or cold. It also has a tendency to shift harshly when shifting from park to reverse or from reverse to drive. I have expressed my concerns with my dealer, and it appears they are aware of the problem, and have told me that gm is also aware of the issue, but they dismiss it by way of saying it is normal. I have had the transmission fluid changed at the regular interval, but this has not cured the problem. Finally, gm is well aware of this issue, and is subject to class action lawsuit regarding these transmissions, and other owners have stated that they too have experienced this shifting issue. My concern is that this will eventually lead to a failure of the transmission and the drive components I. E. , drive shaft, pinon gear, differential housing, anything connected to the transmission. If this failure occurs at highway speeds, a possible loss of control and crash could occur.
