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

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.

The oil cooler lines came disconnected and oil leaked out. Had to have it towed and repair shop fixed it said the front lines where broke and rear lines where coming apart

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.

Coming home from work one morning, the truck all the sudden displayed lights across the dash saying no oil pressure shut off engine now. So I Immediately pulled over and got out to find oil was coming out of everywhere, my front bumper, the hood, underneath. I had it towed to local Chevrolet dealership and they contacted me today to tell me the oil line from the engine had came loose because of a clamp. So I looked up some problems because it was over $1000 to fix it and found there was a customer satisfaction issued through GM because of the same problems within my year and model truck. Are they in contacted GM to see if they would fix the problem and they told me because my model number was included in their customer satisfaction that they couldn’t fix it even though it was the same year and the same type of truck. So I asked them how I got my model number included and they told me I had to go through the national Highway 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 dri

The contact owns a 2019 Chevrolet Silverado. The contact stated that while driving at an undisclosed speed, the contact received a warning message that displayed low oil pressure to turn the vehicle off. The contact pulled the vehicle over and turned the vehicle off. The contact inspected the vehicle and noticed oil leaking from the bottom of the vehicle. The vehicle was towed to the dealer where it was diagnosed that the oil coolant failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The approximate failure mileage was 31,000.

I had known transmission problems resulting in $5974 repairs. I consider this an extreme safety issue. Had the transmission failed in heavy traffic, it would present a dangerous situation for both me and others near me. This is a known issue by GM, nothing is being done to correct this problem.

When put in drive and start driving as I start going it won’t shift and takes longer than normal when finally shifts it’s to hard and truck jumps a lot as if had hit a bump with rear tires, Also while driving in highway truck vibrates to much have already try new tires new rims and different parts of suspension to solve issues but continues to do the same.

*Lifter / Rocker Failure *There was a good jerk of the truck (safety) *Confirmed independently *Not inspected by dealer, police, ect *Small stuttering right before failure

Premature failure of hydraulic lifter and cam which happened suddenly when driving on the highway. Truck had 106000 miles and it was am expensive repair. It caused the truck to violently shake and I had to get towed. Truck had been maintained with all recommended services through the dealership.

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 contact owns a 2019 Chevrolet Silverado 1500. The contact stated that upon reversing out of the driveway and shifting into drive(D), the vehicle jerked several times, then the vehicle responded as needed. There was no warning light illuminated. The contact stated that the failure mostly occurred when the engine was cold. The vehicle was taken to the dealer, where an unknown software update was performed; however, the failure persisted. The vehicle was taken back to the dealer, where the contact was informed that the manufacturer had advised that the vehicle was operating as designed. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not under recall. The failure mileage was approximately 52,000.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving 45 MPH, the vehicle started vibrating and hesitating. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the transmission fluid needed to be flushed and refilled. The torque converter was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 64,000.

Wires were improperly installed during assembly, on truck and rubs on a frame which chafes, which causes the protective covering to get rubbed off causing a short circuit on my wiring harness which causes the "check engine light" to stay on constantly. This is a factory mistake yet they want to charge me for the fix. I also have come to know this is getting too common on Chevy Silverado 1500 and GMC Sierras. GM needs to correct their factory defect for free. This chafing can happen in three different areas on the trucks. These shorted wires can cause failure of the fuel pumps and leave you on the road when the engine shuts down. GM knows about these problems but has not acted on this problem. they never mentioned or noted the wiring problem on my repair summary, Oct. 23, 24, when they were replacing the torque converter. They showed it to me, but never made note of it. They are going to work on it Monday 12/9/24, I will talk of, who's going to cover the cost of this after it's repaired.

Twice the vehicle has malfunction at high rates of speed no brakes no steering and almost caused serious injury to myself and young son the second occurrence I record the last 15 seconds safely to have proof of exactly the speed of disengaged control. For this very reason. Vehicle has been at dealership since 10/28 I’ve had to rent a car 1700.00 and more than 30+ days no diagnostic or response to purchase this defective vehicle with number of same occurrence of brake electric emissions and transmission malfunction.

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.

8L90 Transmission failed. The transmission was inspected by a chevrolet Technician at a Chevrolet dealership and found to be defective, thus rendering the vehicle not drivable. There was an engine light that indicated a TCM problem. The vehicle is currently in the mechanic shop at the Chevrolet Dealership awaiting a new transmission.

Pulling an enclosed trailer with my 2019 Chevy PU. Stopped at a gas station and discovered the tailgate had dropped down while driving. Making the turn into the gas station with the trailer in tow creased the tailgate considerably by the jack on the trailer. Thankfully nothing was noticed missing from the truck bed that was needed for our trip. Very unhappy for the faulty tailgate opening while traveling. Request contact for repair as I see there are recalls on this matter but not my truck when indeed it did happen.

The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 74,000.

Transmission shudder and shakes at high speed and low speeds

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.

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 rear brakes lock up when slowing down. mechanic said its the transmission and that he had seen alot of this in this make and model of truck. The only fix is to clean but that is a temporary fix. The transmission we have is not made anymore. There is a recall in the 2020 model of my truck but doesnt include my 2019 even though it is the 2020 model.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while operating the vehicle, the transmission malfunctioned, causing the vehicle to shudder and vibrate abnormally while changing gear. Additionally, after shifting to the drive(D), the vehicle occasionally lunged forward. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 30,000.

I keep on getting the Service Brake System warning, even when I am not pulling a trailer. When I am pulling a trailer the warning comes on and I lose all braking on the trailer and it usually blows the trailer brake fuse. This has been happening intermittently for the last two years and now is more frequent. Now I heard there is a recall on the same scenario but my VIN number is not included. Now what?

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.

The contact was informed that the grounding strap needed to be repaired. The manufacturer was not made aware of the failure. The failure mileage was 37,551.

Transmission shift hard.

The contact owns a 2019 Silverado 1500. The contact stated that after making a left turn, the “Low Engine Oil - Stop Engine Immediately" message was displayed with an audible dinging chime heard. The vehicle was steered to the side of the road and turned off. The vehicle was towed to the residence. The contact stated that while at the residence he lifted the vehicle and observed condensation leaking from the skid plates. The contact removed the skid plates and noticed that that the skid plates were filled with oil. The contact then stated that leak detecting dye was administered to the engine and almost instantly, the contact heard leaking sounds and turned off the vehicle. The contact then observed condensation on the ground under the engine compartment. The contact then used the UV light to locate the leak and observed that the high-pressure oil cooling line was severed. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 125,000.

-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.

A couple months ago, my wife was backing down a sloped driveway the brakes gave out and would not stop the truck. She had to push the brake extremely hard to get it to stop and the service brake assist light came on briefly. It then went off and the truck's brakes came back. It happened to her one other time in a similar situation going slow in a driveway. Today I was driving and was slowing down coming to a stop sign moving forward when the brakes gave out so I had to push the brakes extremely hard to come to a stop which felt like they were fighting back and I almost hit the person in front of me. The service brake assist light also came on. There are known recalls on this part in prior years of this same vehicle and others. This recall should be expanded to 2019 Chevy Silverado's as well. I should not have to pay to fix a known issue.

The sway bar detached from the frame running down the road due to a faulty installation completed by the production line. My wife heard a clunking sound and recognized instability in the vehicle during turns she immediately stopped driving it until it could be evaluated. Apparently during manufacture the mounting holes for the sway bar were threaded too big for the bolts used so they installed helicoil repairs into the frame which failed allowing the sway bar to detach. I have pictures from the dealership showing the failure and chevy is trying to weld a nut into the frame to be able to reattach the assembly at my expense.

Rupture of Oil Cooler Lines. NHTSA previously completed a safety field investigation. GM issued a bulletin to their dealerships (only). Has both safety and environmental impacts. Vehicle suddenly losses oil pressure and provides a warning light to turn engine off. This will strand the driver wherever and whenever it should occur. I have spoken with GM, they are aware of the problem, but will not recall for the problem. This scenario also exposes the environment to the sudden loss of oil to the ground and surrounding area.

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 hard shift and downshift also has a torque convertor shudder it also has high transmission temp the coolant temp on the dash is above the middle point have been to the dealership multiple times they state everything is normal transmission problem can cause a safety issue on the road if truck doesn’t shift how it’s supposed to.

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

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.

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
