My transmission keeps shuttering during passing gear around 50-55 mph. It causes my truck to slow down drastically. It's always a knee jerk. I've serviced my transmission around 40 to 50k miles.

Right after our warranty expired which was 36,000, the transmission started harsh or rough shifting, delayed acceleration, sudden lurching, and shuddering, hesitating to the point that you don-??t think the truck is going to move or someone hit us from behind. It-??s horrible. Every time you drive you pray the truck is going to get you there safely. We tried to take the truck to the Chevrolet dealer and they insisted there was no recall and it was no longer under warranty. Then we took to a private place and had transmission fluid flushed which made it worse. We are waiting patiently for a recall because we can-??t afford a transmission.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, while accelerating from a stationary position, the vehicle shuddered while accelerating. Additionally, while decelerating, the vehicle erroneously lurched forward. The vehicle was taken to the local dealer who reprogrammed the TCM, and changed the oil which temporarily corrected the failure; however, the failure reoccurred. The cause of the failure was not yet determined. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 41,000.

The first thing that happened was the transmission, driveshaft, and rear end all blew at the same time while I was on the freeway. I had to swerve over and get out of the lane I was in and part of the driveshaft was still sitting in the road and cars were hitting it. There was no lights or anything until it happened. I got out of the passenger side of the vehicle and looked under the truck and there was a flame coming out of the rear end. I was able to extinguish it. It was inspected by delta transmission and they said that the rear end gave out first and damaged the rest. Not even 2 weeks later the second thing that happened was my engine gave out. I was driving on the freeway and the engine stalled out on me and I barely got off an exit before the truck stopped moving. I had to get it towed to a shop where they told me that the 2 rods on cylinders 1 and 7 had given out and that I needed a new engine. Again no warning lights or anything until it happened. This all happened in February of 2025.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds, the vehicle lost motive power and ran sluggishly with an abnormal knocking sound coming from the engine compartment. The check engine, traction control, and two other unknown warning lights illuminated. The contact stated the -??Service ESC-??, engine, transmission system, and emissions notification were displayed on the Chevrolet App. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the lifters had fractured and damaged the cam shaft. The contact was informed that the cam shaft and lifters needed to be replaced. The vehicle was not repaired. The contact stated that while the vehicle was parked on several occasions, the engine was idling rough. The manufacturer was notified of the failure. The failure mileage was 112,000.

Lifters froze up on #4 piston twice, both times going down the highway. Transmission would jerk after shifting gears, had bad torque converter shudder from 18 mph on up. Can-??t pull trailer over 55mph without the whole cab vibrating like crazy

I was driving down the interstate stuck in slow moving traffic going 55 in a 70 in Jacksonville, FL. The Chevy suddenly lit up like a dang Christmas tree, parking brake service, check engine light, lane assist, and EVAC all flashing on the screen. Everytime I hit clear it like a new warning popped up. It started to drive super rough as in bumpy, loud and hesitant. I parked it, turned it off. Waited maybe an hour since I went to class, then came back to start it. Issue was still there. I took it to the dealership who seemed more interested in buying it than repairing it, they said it could be a number of things and estimated 10k even though they couldn-??t tell me exactly what was wrong. They knew, they just wouldn-??t say. Anywho, $100 later for a wacky diagnosis, I left to take the truck to an actual mechanic, who stated the lifters failed which caused a bent rod, which then damaged the cam shaft. We had just bought the truck outright for 27k three months prior and only driven it 1,500 miles. It was estimated to be anywhere between 12-15k to fix. Which we didn-??t have that money and personal loans are too high so we traded it in and took a loss of 17k while being thankful that no one was injured driving this thing. The truck didn-??t even have 80,000 miles yet. It was at 75,000 or 76,000. Truck engines shouldn-??t fail that soon or fail at all and this is a common safety issue with this truck. If you have time, google the main issues for this truck and you-??ll see several posts about people complaining about their truck doing the same and having to do a computer deletion to get the engine to function correctly to prevent this issue.

Vehicle is showing the GM "SHIFT TO PARK" error code on the dash board, when turning the engine off.

This truck has very low miles (22,900) and has broken down on me 4 different times over several years. It will randomly slam into 2nd gear and I will almost loose control as the rear wheels will almost lock up. Then the vehicle will barely move even at WOT. This has caused me to almost be in accidents and is very unsafe. GM knows there is several issues with this 8 speed transmission and cannot resolve it. I am afraid to be in an accident because this thing is so unreliable in it's operation. GM needs to be forced to address this issue. There are multiple TSBs on this transmission that claim to be collecting data and investigating the cause of issues dating back to 2020. Time for a repair!

- Edmonds, WA, USA

I noticed up on start up a warning light comes on & display says brake system failure 62 MPH then goes away. I have been reading numerous other reviews online that they are experiencing the same issue. 2nd problem is when I bought the vehicle I noticed numerous oil spots on the tailgate, I asked a GM representative & they said it was road grime, but I noticed the rear pinon is leaking, so it's been leaking since I bought the truck & the dealership either doesn't know it's a known issue or they didn't want to come out & say it.

- Anderson, CA, USA

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving 60 MPH, the vehicle jerked and briefly lost motive power before slamming into gear. The check engine warning light was displayed on the instrument panel. The vehicle returned to normal functionally, but the failure became a regular occurrence. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure, and the contact was referred to the NHTSA Hotline for assistance. The contact stated that weeks before the failure the oil pump was replaced. The failure mileage was approximately 108,000.

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.

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.

While driving on the highway with my four year old with me the truck jerked and then triggered 3 lights on my dashboard, this made getting to a safe spot uneasy as it was jerking and sounded like it was reving up and down and overall sounded not good. Truck was towed to mechanic and was discovered the lifter failed due to the Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) in that engine model. That failure caused further engine damage to the cam shaft and needs an entire rebuild of the top part of the engine. There were no other indicators that this would happen until it did. I contacted Chevy and they are aware of the situation and offered "cost assistance" only if it was brought to a GM dealership. Given the engine had to be taken apart to figure out what was wrong they said the only way to get assistance was to have the garage put it back together and then tow it there and have their mechanics look at it to determine if they could cover part of it. This isn't a viable option to me seeing how there isn't a guarantee of any assistance and would potentially cost more long term.

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.

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.
