general problems of the 2015 Chevrolet Silverado 1500 - part 1

Transmission just won’t last in this truck and it’s dangerous when you have kids in it.

2015 5. 3 with afm related failure / lifter collapse still within warranty by mileage (5 yrs, 100,000 miles I think), out by years in service, was diagnosed by a gm authorized dealership by a gm master certified technician and under the supervision of service manager. Issue description on 6/18/2025, the dealership diagnosed a failure in the #7 lifter due to afm / afm related failure / lifter collapse. The vehicle’s engine, diagnosed at approximately 58,000 miles and minimal idle hours. While the gm master technician is confident that only one side of lifters require immediate replacement, there is a possibility of damage to the camshaft lobe, which cannot be inspected without significant additional labor. There is also a concern about potential metal contamination in the oil, which could further impact the engine’s performance. I also have many documented repair orders indicating my concern with the transmissions performance.

My engine shakes when shifting into the v4 from the v6 and my transmission shifts hard as well as a dieseling affect when shifting from 2nd gear to 3rd gear. Rear main seal was replaced 1000 miles ago and now has to be replaced again due to the rapid shaking of the v4 cylinder deactivation(which was a terrible way to make the reliable 4. 3 lt engine unreliable).

Experienced a problem with electrical theft deterrent system and it shut the vehicle off while driving. I tried to start the vehicle and nothing happened except it said theft deterrent system. I took the key out tried starting again and it turned over immediately. The dash said theft deterrent and I clicked dismiss but the dash icon (a car with a lock light) remained on. I then drove 11 miles home. I turned on my directional proceeded to brake upon approaching my driveway. As I attempted to turn the steering wheel the vehicle completely shut off. The info system stating theft deterrent active. I lost power steering and brakes. I needed to press the brakes with great force because the vehicle was headed towards the sidewalk and a road sign. Steering was virtually unresponsive. Vehicle stopped as the tires reached the curb and approximately 1 ft from the sign. Placed vehicle in park and started it back up. Pulled into my driveway and the info system stated I need to roll the drivers window down and the up to deactivate. I have checked all battery connections are intact and tight. The battery, starter and alternator were all checked and fine. I have no idea what caused this dangerous behavior. The incident happened on MA rt. 126 988 s. Main st bellingham MA 02019.

The valve body on my transmission failed and needs to be repaired again. It was already replaced by gm, 1k miles later it failed again.

Transmission failure at 133,000 miles due to faulty tourque converter … which was replaced after … I repeat after… replacing all components that failed because of the faulty torque converter … so now its showing same symptoms as did before failed … only 30,000 since repairs.

While on the freeway at 65mph the truck experience a hard gear shift, loss of acceleration, went into shut down, lost steering assist, and brakes became hard, lights came on the dash for transmission issue massage, as well as check engine light. Safety became a major concern with loss of power in the mids of a flow off traffic at freeway speeds. Vehicle had to be towed.

The torque converter with the 6l80 transmission went and destroyed the transmission in my 2015 silverado. Which is going to cost me thousands of dollars to fix. With the 10's of thousands of people affected, chevy should of done a recall on the torque converter and/or transmission. There were no signs/symptoms, the truck started shaking like I was driving over rumble strips, no check engine light. I was able to get it to a mechanic immediately and it sits there unusable at this time.

In the middle of driving the truck stopped working and wouldn't accelerate. No light for the engine was on and no warning. Truck won't restart.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated while driving 70 mph, there was an abnormal sound under the contact’s feet, and the vehicle started shaking abnormally. The contact stated that the vehicle lost motive power. The vehicle was steered to the side of the road and restarted. The vehicle was taken to the dealer where it was diagnosed that the cooler lines and transmission needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 123,341.

After start up and when putting the vehicle into drive the transmission seemed to not recognize and then began clunking into gear. While driving it felt like it was slipping and racing with no response. The vehicle became to precarious to drive on the road because the gears wouldn't shift and the vehicle decelerated quickly and would not accelerate upon demand. I felt as if I could endanger others and lose control and endanger myself and the occupants of the vehicle. We chose not to drive it and bring it in for an assessment and ultimately was told of the problem and agreed to the repair to gain our vehicle back in safe working condition. The vehicle needed a total transmission rebuild and torque converter as well as other tranny related items. No warning lights but we did begin to hear a whining noise while cycling through what seemed to be the gears.

My transmission is not shifting into gear and is not pulling anymore. Also,the transmission has been shifting hard and jerking into and out of gear while driving. The jerking into gear while driving has been going on since I purchased the truck in 2015. I told the Chevrolet dealership about it a few times. I even asked if there was a recall. Their answer was, no recall and all of the silverado transmission pull like that.

Torque converter failure. The torque converter went out suddenly with no warning of possible problems. No engine, or transmission warning lights. Just suddenly started jerking when accelerating. Rpms jump every time it jerks.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds, the vehicle began shuddering. There were no warning lights illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 64,000.

Transmission shudder and hits hard at times.

Transmission sounds different and clunks lightly once in a while. There is a known problem w this type of transmission but gm is not accepting it as a recall concern and many dealers are ignoring repairs are needed.

The transmission has failed in less than 150,000 miles. I was driving in traffic and lost gears. I stopped and tried to get back going and I was stuck being a traffic hazard to the other motorist. I talked to a local transmission shop and he stated that the 2014-2016 silverados are known for transmission problems even when they were new. He’s rebuilt hundreds of them and Chevrolet should have recalled and fixed them. There were no warning lights or anything through the truck.

Transfer case is shifting to neutral while driving.

I have been having problems with my vehicle cutting off and I would jump start. It often gave be a theft code on the dash. Until one day it stops starting all together. Now to find out there is a recall on the electrical system I was told by my mechanic please contact me so I can get this resolved will be with out of transportation, paying insurance and a car note thank you.

The truck shutters and shifts horribly hard. Check transmission light is now on.

The transmission began slipping and failed at 106,000 miles in spite of obtaining all recommended services throughout the life of the vehicle. It failed completely while driving, which was a major safety issue. It now needs a new transmission. After searching online, I see that numerous owners have reported issues with the 2015 chevy silverado transmission. There were no warning lights. It began to make a noise and a shaking and failed about one week later.

My flex fuel sensor went out at 58000 miles, transmission always giving problems on all chevy transmission & should be on recall.

4wd (transfer case) malfunctioned, locking the truck in 4wd mode and making road driving dangerous and potentially damaging to the truck. No prior issues. $500 software repair.

A 2015 Chevrolet silverado seemed to be running rougher after an oil change. When inspected by dealership, litha Chevrolet located 200 east cypress Ave in redding CA, they identified lower end knocking and lifter ticking noise. Also identified was po300 was randomly missing and po324 knock sensor performance. The dealership recommended total engine replacement, after reviewing the report. The 2015 silverado is currently out of commission. It is not roadway safe. The silverado has been serviced regularly as recommended and has not been in any collisions in the past. The truck has had one owner previously, my father, who left me the truck when he perished. I relied on the truck for daily and extended transportation for myself and my children. I have maintained excellent care of the 2015 silverado with regular maintenance and services. There is no explanation of this issue other than it was caused by faulty equipment from the manufacturer. If you can provide any information regarding how to fix this please contact me. Thank you.

It started out with the transmission slipping/jerking at about 50 mph. Then as it progressed it began whining. We were barely able to get it to a mechanic to have it looked at. We were told it was the torque converter which caused the transmission to need to be replaced.

Vehicle went into neutral while driving on highway. Depressing accelerator only caused engine to wind. Pulled over into a parking lot, put vehicle into (p)ark, turned engine off, restarted ignition, and transmission began to function again.

Transmission keeps going in neutral all by itself. Me an my family has almost got hit several times.

For several years this truck will at times start "grade braking" on its own. In other words, at speed, 55 mph, the computer chip will tell the transmission to downshift to assist in "grade braking". The danger is that it actually speeds up the truck, and while attempting to stop at a stop sign, (or light), the truck is actually speeding up, while I am actively pushing on the brake pedal to stop at the light. I ended up having to replace the transmission with a new (rebuilt) transmission. I hoped this would end the problem, but now once again, I have the problem occurring with the replacement transmission. Gm tells me they cannot program out the grade braking component. This is a very dangerous situation in which one day I will be unable to stop where required, due to stopped traffic, or a stop signal.

My wife came home and told me there was something wrong with our truck. I went and inspected it and found nothing. The next day I drove the truck about 30 miles up river. Coming home I was traveling around 55 mph the truck came to a sudden slow down as if I had locked up the brakes then drove fine again. This happened three or four times not as bad as first time. While in town stopped at a light it tried to take of. Not like something giving it gas but like it was in gear and the brake wasnt going to hold it. Almost put me into a school bus ahead of me. Then the rest of the way home it kept binding down and releasing then binding back down. Hard to control but not necessarily a break problem. Its something else. I have worked on vehicles all my life, professionally for 25 years. I never seen a vehicle do this. It has to be in the transmission. Maybe something in the torque converter would be my guess. I have heard of the issues with the 8 speed ever sense this happened I have parked this truck. I cant afford a need transmission that doesnt actually fix the problem from what I hear. I feel gm needs to do something here. At least pay for the parts to fix it.

Driving 25mph for 3 miles leaving my house speed limit increased to 55 and as I stepped on gas to speed up truck shuttered, shook, and ck engine light came on. #6 cylinder has no compression, found info about common chevy problem 122000 miles.

Vehicle is shifting hard between 1st and 2nd. It only seems to do it at lower speeds. The rpms had a shudder between and only once the truck has been running for awhile. Has been in to an independent service dept. At the local dealer where it was purchased and has had all work done since purchased. There are no warring lights or check engine messages. They flushed all fluids and hooked to diagnostic machine found nothing. Had it back for a week and it did it again. Took it back to them and had them ride along so they could see what it was doing. They replaced the torque converter although the shudder is gone but it still shifts hard between 1/2.

Transmission failed at 70 500 miles.

Nhtsa campaign number 18v586. Gm’s recall is 18289. Power steering at low speeds with voltage drop causes power steering to lose control.

I am having issues with my transmission. When I first turn on the truck in the morning, put it in gear, and lightly accelerate the truck accelerates way too fast then cuts out the power. It is enough to throw me forward or back in my seat and it honestly is frightening. I am also having problems with the vehicle shifting incorrectly causing me to have no power or a sudden surge of power. This is usually when I have slowed down and them am trying to accelerate again. Also, when I am slowing down to stoplights, the vehicle will occasionally shift down to too low of a gear and act like I am slamming on the brakes. I have had several close calls with this truck due to this issue. Gm knows about the issue and has refused to recall the vehicles that are having these problems. They are recommending changing out the fluid multiple times at the owners costs. This has resulted in several class action lawsuits. They also have gone to the lengths of changing warranty coverage to no longer include abnormal shifting. This is not safe. This is causing accidents and they are actively covering it up. Please help the hundreds of thousands of people that are having issues. We need your help, I need your help and gm is no longer standing behind their vehicles.

Transmission slipping, set cruise control and it would engage for some time and then disengage without warning. I followed all maintenance requirements for the transmission like flushing the transmission at the appropriate mileage.
