Transmission doesn-??t shift smoothly and often slams into second gear from first very hard. Downshifting on rare occasions shifts to a lower gear before necessary causing rpms to go from 2800-3000 up to 4500-5000. I have to touch the gas real quick to upshift. Also brakes seem to require extra strength to engage if hard braking is required. Like the booster is not reacting properly.

The contact owned a 2018 Chevrolet Silverado 1500. The contact stated while driving at 80 MPH the steering wheel became stiff and the vehicle would not brake without any warning. The contact desperately pressed on the brake pedal but the vehicle would not brake, causing the contact to be struck by another vehicle on the driver's side. No one was injured and no major damage to none of the vehicles. A police report was filed. The vehicle was towed and deemed a loss. All the air bags deploy but the front driver side. The manufacturer was not unable to reach them. The failure mileage was 69,000.

The brakes failed to work when I was in a parking lot. As I was pulling into a parking spot, the brakes did not work even when I pumped them. I was going approximately 3mph. It startled me, so I put the truck in neutral and then into park. Then I turned the vehicle off. Fortunately, this happened in a parking lot and I was able to avoid hitting anything, including a pedestrian. Also, this put my husband and me at great risk because if I had not chosen to go back into a parking lot, and had gone into an intersection and been unable to stop, I could have entered the intersection and been in a serious accident. The truck functioned well enough to get to my dealership. I avoided driving it for a couple of weeks until they could run diagnostics. Between the time it first happened and bringing it to the dealership, the problem did not occur. However, when the technician was driving it into the shop, it happened to him too. They did perform diagnostics and found a problem with a brake Pump 3.280 (Part No. 12696313). I had it repaired at my own expense ($587.65) on Nov. 22, 2022. NOTE: This truck has only 25,673 miles on it. There has been a recall for this problem on Silverados from this year, but my VIN number was not included in the recall. There were no warnings prior to this event. I would like to have this repair cost reimbursed.

I have done some research and found other trucks same year and make have had the same problem and have had recalls but the problem is when I hit the break the lights will all flash like the truck is going to stall and it will say service trailer break system and stablitrak system and will even shut my truck off while I-??m driving causing me to have to either pull of the side of the road and start my truck back

On Saturday Aug 6th, 2022 my girlfriend and I were driving in my 2018 Chevy Silverado and the car just came to a complete stop really hard. Once the truck froze up, the car would go FOWARD but very slow, jerkish, and sluggish. We were almost hit by three cars behind us when the truck froze up. The truck was towed to the dealership where they diagnosed the truck with METAL SHAVINGS in the TRANSMISSION. And the engine light came on four weeks after I bought the vehicle last October. This time-??. There was NO engine light on. Nothing displayed on dashboard.

I'm getting a persistent message about servicing the trailer brake system. There is no trailer hooked up to the vehicle. The message covers the speedometer and chimes over anything else.

- Florence, KY, USA

While driving down the road, I received several non stop alert messages stating "Service Trailer Brake System". The messages were non stop and while I did attempt to acknowledge them and dismiss the alert, I was distracted from driving and had to pull over to attempt to acknowledge or dismiss the alert. After several minutes, I was able to dismiss the alert and continue on my way. This happened on Tuesday evening around 5:00 pm on August 30, 2022. I called Mike Anderson Chevrolet on Wednesday August 31, 2022 around 12:30 pm to advise them about the situation and was told it was water in the wiring.

Service Trailer brake system audible message appearing due to faulty wire harness between body control modules.

While towing a trailer the service trailer brake system light/alarm came on, trailer brakes stopped working and the alarm persisted for hours. It was extremely distracting and dangerous, and interrupted hands free phone calls.

I purchased a certified pre-owned 2017 Chevy Silverado on June 6 of this year. On June 13th, on my way back from a 10-hour trip, where I was towing a trailer with a car on it, my trailer brakes suddenly stopped functioning (about 4 hours from home). Not only did the trailer brakes stop functioning, but a warning message popped up on the dashboard "service trailer brake system". But this warning message didn't pop up just one time, it kept coming again and again and again and again and again, relentlessly chiming and distracting me from driving, it covered my speedometer readout, it prevented me from receiving or making voice commands, prevented me from hearing phone calls, and prevented me from listening to music. The service warning chime also prevented the turn signal chime from functioning. So for a full 4 hours, I was constantly reminded with a service trailer brake system chime, was unable to hear my turn signal chime, was unable to listen to music or make a phone call, and was unable to see the digital readout of my speed. The vehicle had been rendered completely undrivable, and I absolutely will not hesitate to say that the vehicle was not safe to drive in that condition. Especially if you consider that I was towing 5,000 lbs with no working trailer brakes. Your vehicle's defect endangered my life.

Trailer brake issues. Blows fuses non stop chiming in the dash. Once fuse blows it doesn't chime anymore. Replace fuse and it's non stop all day every day. Been dealing with it for a couple years. Tons of people have the same problem.

A faulty internal computer constantly beeps a warning about "trailer brake system" when there is no trailer attached to the vehicle. The beeping is extremely hyperactive and non stop and distracts you from safe driving and interrupts all other audible functions (such as turn signal blinking & navigation voice commands) to render the vehicle unfit to drive.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle would not properly accelerate while depressing the accelerator pedal with the check engine warning light illuminated. Additionally, while depressing the brake pedal, the braking system malfunctioned causing the braking distance to be extended. The cause of the failure was not determined. The manufacturer was contacted and notified of the failure. The local dealer was not notified of the failure. The approximate failure mileage was 96,000.

The trailer brake system warning suddenly came on, disengaging my cruise control. My cruise control has not worked since. Also, the stabilitrac warning came on and has not left. Ever since then I have been hearing a squeaking noise driving at low speeds.

- Belle Chasse, LA, USA

For months now, my 2018 Chevy Silverado 1500 has a -??service trailer brake system-??notification on the the dash that repeatedly pops up every 5-15 seconds while the vehicle is on, including while driving. This, along with the pinging sound that comes with the notification, makes the vehicle difficult to drive due to the constant distraction the notification makes. I have tried taking issue with the dealership but they are not helping whatsoever. From my own research online, I have seen hundreds of other people experiencing the same issue. Please help us eliminate this distraction by forcing a recall and thus making the roads safer for everyone. Thank you.

While coming to a stop at a traffic signal I experienced a sudden braking loss. The pedal began to vibrate and I noticed an extreme reduction in braking power. I then got a prompt on my dashboard saying -??service brake assist.-?? I narrowly avoided the car in front of me while trying to stop. I contacted GM and they claim even though my year make and model are the same as vehicles being recalled my specific VIN# is not.

Bought the truck new. Never towed a trailer till well after warranty. Service trailer brake light keeps coming on continuously. Then no trailer lights or trailer brakes. Found 2 blown fuses but now the same thing is happening again. After my research I found tons of information that lots of other people are having the same issues. I have not pulled my RV since because I'm worried about it not having brakes. It's quite large and without them this truck would not be able to stop in case of a quick emergency.

- Frostproof, FL, USA

My 2018 chevy silverado started making weird squeaky/popping sounds it almost sounds like something is rubbing against something else when stepping on the break pedal. When driving at any rate of speed the pedal seems to not make the squeaking noise but when I make a complete stop for example at a traffic light and let go of the break pedal and press again I can hear that noise loud and clear even passengers can hear it, Another example would be going in a drive thru of a restaurant that pretty much break pedal is used every 3 seconds as you pulling forward there the noise becomes constant every time stepping and letting go of the break pedal. My silverado has about 80,000 miles on
