general problems of the 2018 Chevrolet Silverado 1500 - part 2

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.

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.

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.

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.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while attempting to stop the vehicle, the brake pedal extended to the floorboard, extending the stopping distance. The vehicle was taken to the local dealer who diagnosed that the vacuum pump was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA campaign number: 20v603000 (service brakes, hydraulic). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 30,000.

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

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.

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 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.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving approximately 2 – 15 mph, the vehicle shutoff while depressing the brake pedal. The contact stated that the “check brake monitoring alert system” was displayed. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure and the contact was informed that the vehicle was not included in NHTSA campaign number: 20v603000 (service brakes, hydraulic). The contact stated that the vehicle experienced the failure listed in the recall. The approximate failure mileage was 74,000.

2018 Chevrolet Silverado 1500 . 1/20/22 slow driving in a parking lot, applied brake to slow down for a stopped vehicle and pedal was soft and went almost to the floor could have killed someone, this happened 3 times within 4 minutes power brake assist warning came on, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. Called local Chevrolet dealer jenkins Chevrolet of homosassa service department told the manager that my truck was working right they said it was not involved in a recall my truck showed all the symptoms in this recall, NHTSA campaign number: 19v645000.

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.

Trailer brake system failure we noticed the sudden drainage of power resulting in death of battery multiple times alert was present after we notice the loss in voltage in battery to battery drainage after research I found that it is usually a short or a bad wiring harness which causes this and could pose a danger considering how I at one point in time have trilled things this could be an issue and a danger to others on the road.

On 10/03/21 at approximately 1251 hours, I was driving my 2018 Chevrolet silverado which is the vehicle with the above mentioned VIN. As I was traveling towards a heavily traveled intersection in my current city, I approached a steady red signal on the traffic light. It should be noted that this particular part of the roadway is a slight decline towards the intersection and traffic control signal. It should also be noted that on this particular day, there were no inclement weather or roadway conditions that would affect the vehicle to deviate from normal maneuvering. As I applied the brakes at a reasonable distance from the stop light, almost all pressure and power towards braking was lost. As a result, I was forced to apply extensive pressure to the brake pedal as the vehicle failed to slow and stop in a timely fashion. After gaining some braking power, the vehicle and brakes began to shake and produce a clunking sound. This was troublesome because had I failed to stop in a timely manner, I or other motorists could have suffered serious injury or death as a result of a crash at a heavily traveled intersection. Prior to this incident, there were no warnings or alerts provided by the vehicle, dealer, or manufacturer about this issue. As the event occurred, an alert flashed on my dashboard that read “service brake assist. ” following the incident, my vehicle was inspected by a certified mechanic. Said mechanic deemed that the problem with the braking was a result of a failure of the brake booster vacuum system. After doing some research, it is apparent that other years, makes, and models of GMC products suffered the same issue with the braking system. Said issues were remediated with a recall by the manufacturer. This defect also caused numerous vehicle crashes with reported injuries.

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.

Service trailer brake system warning has been activating, without a trailer attached, since October 2021 off-and-on. When this occurs it has created a very distracting situation while driving due to the relentless chiming of this warning notice.

Service brake assist warning on message center. Brakes go from power to manual.

When driving the brake pedal goes soft. In parking lots, areas of low speeds, making u-turns the brake pedal goes all the way to the floor and doesn’t stop. The brakes completely stop working until you release and pump the brakes again quickly before hitting something or someone.

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 it.

Truck loses power driving down the road. The service trailer brake system warning comes on the dash. The battery dies because of this also.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the service brake assist message was displayed, and the brakes were slow to engage. The vehicle was taken to the dealer and diagnosed that the brake booster pump had failed and needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 60,000.

Brake pedal gets hard and you will need to step on the brake hard in order to brake.

The trailer brake control module stopped working on the interstate while pulling a 37' fifth wheel camper. This defective part caused the truck to not have any electric brakes on the camper. A warning message appeared on the dash. A new trailer brake control module fixed the problem. Since the vehicle was out of warranty (37,878 miles) the part was not covered by the dealer. The dealership where the part was purchased informed me that it was a common problem. This problem occurred while traveling at 65 miles per hour. There was only the truck brakes to stop the camper without the trailer brakes working. This is a serious problem and should be addressed.

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.

The dic and infotainment both change settings on their own. It will change radio stations or call people on the infotainment and the dic will change information displayed. The safety issue is it will also flash that the trailer has been disconnected/connected and when it thinks the trailer has been disconnected the trailer brakes will fail to function. It is a known problem with the display issue but I am unaware of any reports on trailer brake function. I have had a few serious conditions on two trailers when the truck does not recognize the trailer being connected and fails to apply the brakes.

Reduced power steering assist engine stall ipc / radio / hvac goes blank various dtc. Had my head lights flickering, had stabilitrak errors, power steering errors, and the worst of all, the steering wheel jerking out of my hands. Isnt my video but similar when I was driving about 5mph https://youtu. Be/cwamophnxg8.

Abs (trailer braking system) and stabitrak warning lights randomly come on while driving and remain on until vehicle turns off. On multiple occasions the rear wheels have locked and steering becomes difficult even when brakes are not being applied. This has occurred while driving at varying speeds and in varying weather conditions. Vehicle has been checked by dealer on 3 separate occasions for this and service was reported unable once lights have gone off. Said incident has occurred approximately 30-50 times over the past 18months.

At low speeds, such as parking lot, or traffic jam, and even while at a stop light, the brake pedal pushes up and becomes very hard. The brakes stop working and the truck must be taken out of drive. Chevy has issued a recall on silverado trucks 2014-2018 equipped with 5. 3l motors the recall number is 20v603000. Everything that happens as a result of the faulty brake assist is exactly what is happening to my 2018 silverado (5. 3l) bomnin Chevrolet dadeland and chevy is telling me that my VIN number doesn't qualify me for the recall, yet my truck description and brake problem, both match the recall perfect. To add insult to injury bomnin charged me $630 and when I went to pick up the truck it is exactly the same. No brakes at idle.

I started my vehicle and put the truck in reverse to back out of a parking spot. Gave the truck gas and it wouldn't accelerate. Put the truck back in park and looked at the guages and there were no rpm's showing on the cluster and the oil pressure was at zero. There was a message that said trailer brake system on the screen. I turned the truck off and on again and the same thing happened. I put the truck in drive and it would move forward but the motor ran very rough and there was no power steering. I dismissed the first message and another message popped up that said "steering assist is reduced, drive with care. " I pulled into another parking spot, turned the truck off, and waited for a ride. I started the truck when my ride showed up to make sure it was still not working and it was as if nothing happened before. The truck had no issues on the 16 mile drive home. Got home and turned the truck off and started it again and the message came back up and the issues came back. I have a video of the trailer brake system and me shifting the truck and the guage cluster. I have a picture of the steering assist message.

While driving on 30-40mph and hit the brakes slowly, it feels as if the pedal is gonna fall off and can also feel a vibrate on it. It also stalls as if the brakes are being pressed but I'm not, this happens usually in the beginning after being turned on and then stops doing it after reaching the middle of the temperature.

Started having soft/hard braking issues when going at low speeds. Pump the brake petal a few times to try and apply more pressure but does not do the trick. Do not see any issue's with leaks or damage. Seen recalls for vacuum pumps with the year and model the same.

While driving 41-60mph, the truck starts to idle as if the brakes are being pushed on one tire and the brake pedals and gas pedal tend to vibrate as if it were to fall off. After awhile doing that, the stability control light message comes on after reaching the middle of the coolant temperature and the problem goes away. Seems like it does it when it's on low temperature.

Loss of power due to vacuum pump. Message pops up on speedo saying service brake assist as the brakes stop working. Happens at slower speeds while moving (city driving).
