No check engine light come on until continued driving over 15-20 miles. Transmission slams into second gear when taking off or when stopping it may or may not downshift into first causing safety issues when in traffic. Possible electrical error or clutch inside transmission. On this model it is a sealed transmission so no way of identifying if metal shavings come out with a transmission flush. The issue only happens when vehicle is at temperature, if under and still cool drives perfect but as soon as it hits the temperature of 210 it slams very ugly.

Transmission jerking on downshift between 3/2 and 2/1 gears! I have seen GM has been aware of a recent transmissions issue with 2012-2018 plus 2019-2022 years

6l80 transmission out of no where started kicking in and out of gear while in busy traffic. The motor would rev up and then kick itself back into gear multiple times. This wasn’t stop and go traffic also moments later i was at a light turning left as i did the vehicle start this losing power to the transmission except this time i was in the oncoming traffic’s lane trying to turn. Thankfully the other vehicles stopped although it could have ended much worse.

The transmission has been slipping since the truck was brand new (<100 miles) and has always slipped but recently became worse and slips all of the time. This is a known issue with this transmission and should be included in the recall. The transmission slipped going around a curve and almost lost control of the vehicle.

Bad torque converter cause transmission to totally fail. Had chevy do transmission flush,2 yrs ago. Back in Aug 2024, transmission started to slip,while driving,then totally failed,no forward or reverse gears,nothing, had truck towed into chevy dealer, almost $7000.00 later,transmission had to be replaced.

I own a 2018 Chevrolet Silverado (8‑speed, ~81,000 miles). The engine has been audibly ticking, and the dealership confirmed hearing it during diagnosis. This aligns with known AFM lifter collapse issues in the L86 Gen V V8, a design failure rather than simple wear. I’ve consistently used premium Schaeffer 0W‑20 synthetic oil, changed regularly on schedule. Maintenance logs and receipts are available. So far, the engine hasn’t completely failed, but lifter collapse can spiral into catastrophic camshaft or short‑block damage—with no advance warning and high risk of sudden failure. I haven’t had an accident yet, but the ticking is driving home how precarious this is—one mile closer to a full grenade without warning. I’m reporting this in the hope NHTSA will identify a widespread safety risk in these L86 lifter failures and prompt a formal investigation or recall to prevent sudden engine failure in similar vehicles.

Transmission failed and truck shut down mid road while going uphill. Shifting jumps when gears are switched and power jumps and goes down while stepping on gas pedal. At first it showed a check engine light but because i was traveling i had to skip and tried turning on again. It happened at least 5 times while on the road that day and now shifting is messed up and jumps while stepping on gas. I inspected and took to a mechanic for an inspection and said need a new transmission unless there is a recall because it happens to many 2018 chevy silverados 1500.

Hi i toke in my truck twice because of it was jerking was told it was fine noting was wrong my truck is now doing it so hard it feels like I been hit by another car

Transmission failed at approximately 120,000 miles. All maintenance had been done and 90% of miles on vehicle were highway miles. Appears as though there's a thermostat mounted on the exterior of the transmission that is prone to failing around the 100,000 mile area, and when this part fails, there is no transmission fluid circulating to be cooled, so the transmission gets so hot it fails. There are tons of youtube videos from many GM owners that have had to spend thousands and thousands of dollars to replace the entire transmission, when General Motors knows of the faulty part.

2 separate lifter failure incidents at 61,000 miles. One failure, happened on a busy interstate, while flowing with the speed of traffic. Truck started to misfire, jerk and blow smoke. I had trouble getting to shoulder of highway to get out of the speed of traffic. The issue was a collapsed AFM lifter # 6. All the lifters were replaced on the passenger side on my dime. 450 miles later, I had to limp again to the repair shop that performed the previous repair to find AFM lifter # 4 failed this time. GM has been knowing about these lifter issues for many of years and this is a safety concern while on busy highways.

The engine/ transmission has been rebuilt 3 times now and still having issues. The RPM goes up out of nowhere. Something is wrong with the truck. I have taken it to my mechanic over 10 times in the past year. It is still having transmission issues even after being repaired 3 times by a transmission shop.

So the recalls were done on my vehicle in September 2023 , I purchased the vehicle in August and after the recalls were performed the truck would seem different but I thought it was just me, we'll I had an alignment done because it was driving crazy , this wasn't done at the chevrolet dealership, so recently we've experience some braking issues and pulling off to the side well I took it to the ryan chevrolet on a thursday and the mechanic kept the truck until Monday so he can diagnose the issue. We'll then he says nothing wrong but recommended I pay for an alignment because ones never been done the original pins were still attached. I declined because I knew better and so he charged me 80. 00 times 2 because I iefused, he was diagnosing the 2 different things I told him we were experiencing. These are the things that can occur if If the recalls arent taken care of, but he didn't care about my concerns, nor did he want to listen , o me I went to big o and I asked about the alignment and they showed me mt truck is perfect in alignment. The brake issues and the going off to the side are getting worse.

Vehicle shuts off while driving in traffic at low and high speeds stabilitrak service light comes on and the vehicle dash goes dark Radio and temp control panel go dark/ black

2018 Chevrolet Silverado 2020 was under warranty (22,000 miles)….felt a little vibration in my steering wheel and suspected a transmission problem and called the dealer’s service department. I told them what I felt and they said…yes you have a transmission problem (that Chevrolet knows about) bring it in and we will fix it. The fix was…change transmission fluid to synthetic. Now I was not comfortable with the repair but what can I do. I also know changing to the synthetic fluid can handle higher temperatures and will not breakdown as quickly. So my point is Chevrolet knows and knew about the problem and did not even think about a recall due to the expense it would cost them. Chevrolet expects me to absorb the cost of a manufacture problem. Last year was the start of my families transmission problems. It started May of 2023 with my 2014 Silverado’s transmission (175,000 miles) and ended up getting it overhauled. The truck was not abused. November my 1st grandson’s 2018 Silverado’s transmission failed, December 2nd grandson’s 2015 Serria’s transmission failed. I also recently (3 days ago) found out my friend’s 2018 Silverado went failed last year. All within a 6 month’s period. Now I have lost my 2018 Silverado transmission (mentioned above) with 88,000 miles. This is just my family…I really can’t imagine what is going on country wide. All of the above events has prompted me to look into this problem. Every transmission shop and dealer is telling me Chevrolet knows and knew about the problem…I can go on. I am very concerned and will not stop at getting resolve with GM/Chevrolet taking ownership of the transmission problem. Sure I want help...but I also want to help others with the same problem.

Rear sliding window with defrost started sizzling sound than emit a bunch of smoke into the cab. Shut off rear defrost, preventing a fire. The window than shattered. There is a recall in Canada for this very issue. We live only a hour south of the Canadian border. GM says Canada get colder so that’s why the issue is up there.

Rear window defrogger overheated and caused the back electric sliding window to shatter and when door was closed the window blew out!

Doing 65mph on interstate on cruise control, the transmission went into 'false neutral' and engine revs went sky high. Truck slowed quickly, almost got rear ended. After that, the transmission did engage and I barely made it home. Very dangerous! Transmisison had to be rebuilt. Only 126,000 miles on a 2018 truck.

Vehicle wouldn't accelerate while in moving traffic. Rpm gauge would move but speed gauge would not and vehicle would not accelerate past 30-35. When I pulled over and put my vehicle in park then attempted to put in drive, it would not move. Transmission light turned on. Had it towed to a mechanic who after diagnostics, states it's definitely the transmission/torque converter.

Vacuum Pump is leaking oil and internal components are rattling indicating imminent failure and that is a safety hazard for the vehicle and passengers. Oil is being slung all over the front of the engine and multiple belts creating additional operating hazards for the vehicle and passengers. There was a recall concerning reprogramming software to reroute air pressure to the brake system and prevent total failures. Also, technical service bulletin addresses related issues to vacuum pump failures and other affected system components. My vehicle is available, no one has looked at it, we are in danger every time we ride in this condition, no indication of failure other than those already stated. My truck is going on 6 years old and 118K miles. Hardly the time for a brake system failure for a normal use vehicle. This is a safety hazard that GM has created by utilizing faulty components and should be treated as such with all vehicles affected recalled for replacement before vehicles and passengers are seriously injured.

Transmission issue!! Jerks on downshift as well rpm ramp up after shift of gear in 2nd to 1st gears

Last night the truck wouldn’t turn on. The battery had died 4 days after the car was serviced at a local Chevy dealership. I turned the truck on this morning, with what seemed like it didn’t want to turn on and now I’m getting an alert “trailer brake system” i will be contacting the dealership once it’s open

While driving my 2018 Silverado, the 5.4L, 327c.i. engine began idling very rough, shaking and periodically stalling. The check engine light began blinking and it threw codes PO308 & PO301. After compression test & new plugs/wires, it was found that the injectors had open circuits on injector #'s 1 & 8. The only way to replace the injector is through the bank. In this case both banks 1 & 2 were affected. Cylinder #1 is through bank #1 & cylinder #8 is through bank # 2. After removing the intake manifolds and injectors, it was found that the injectors were not providing fuel to the engine causing a misfire on 2 random cylinders #1 & #8. Called the dealer to order parts and discovered they have already been superseded. Original part# is 12698484 and it has been superseded by part# 12710481. Then injectors were replaced & new intake manifold gasket installed w/ proper torque. After repair completed and engine tested, the problem was resolved. Repair shop's invoice will be attached for reference.

My truck has been into the dealership repeatedly from Aug 2024 to where it sits now to this day because of the engine and the electronic fuel management system. This fuel management system has destroyed my engine by allowing excessive oil consumption to which it turns the oil black. The engine goes from v8 to 4 cylinder to save on fuel which makes the engine work harder. It causes the rocker arms and pistons to work harder which makes them fail. These problems have occurred with my truck and now the dealership wants 20,000 to replace the engine when they worked on it continuously even after my warranty period had expired. Keep in mind that they were still fixing these problems when my warranty hadn't expired yet they fail to fix it properly. I make payments on a truck that I hardly ever get to drive. I have service invoices to back up my claims. There are numerous others that are dealing with this problem and it's all over the internet so i am not the only person
