July 2024 my 2019 Chevrolet Silverado got a message of 'brake system failure will not go over 43 mph'. Computer reset twice by local tire dealership. On Thursday September 26, 2024, while driving breaks STOPPED working. Vehicle would not come to a complete stop. Brake pedal hit the wall and still not working. Had to release the gas in order to put the vehicle into a complete stop. UNSAFE, VEHICLE COULD NOT BE DRIVEN. ALMOST CRASHED. Had to get a wrecker to tow it home.

Was driving and the engine died, lost power steering, lost gauges (No speedometer, No Tachometer, Gauges quite working at all) and lost power brakes. Had to try and pull over and was not able to stop or steer easily. I almost hit several other cars and a guardrail trying to stop and steer to emergency lane. After I got stopped, I was not able to restart my vehicle, the starter just kept running but the engine would not start and gauges didn't work. I had my vehicle towed home and started trying to figure out what happened. Put my code reader on the truck and it showed 12 different codes including ECM/BCM failure. I started checking fuses and relays but everything was good. Finally found the problem at the ECM. There was a wiring harness that was not secured and was rubbing against the frame of the truck. One little yellow wire had rubbed through and shorted out which killed the whole truck. It looks like the manufacturer didn't secure the wiring harness in several spots which allowed the wiring harness to rub on the frame and the mount that holds the ECM. The mount for the ECM has started to rub through a different wiring harness and had started rubbing through wires in that harness but I caught it in time.

The brake system went out last month on my vehicle. While driving down a road approximately 35 mph I went to stop the vehicle and realized my brakes went out. I had to continuously pump the brakes to avoid hitting the car in front of me. When I hit the brakes several codes came up on my dashboard. Then the brakes began working again but the lights on the dashboard stayed on so I went to a parts house and they checked the codes. There was a code for the brake sensor. They cleared the codes at the parts house I did not order the sensor because the warning lights went off and I had no more problems with the brakes. Sunday, July 7th, I started the truck in a parking lot. As I was backing out of the parking spot the power steering went out and I almost hit the car parked next to me. Again the dashboard lit up with codes. I had no choice but to drive the truck to my house with no power steering. It was difficult to drive the truck back home and then to the Chevrolet dealership the next morning. I presently have the truck at the Auto nation Chevrolet. When I brought the truck in to the service department they hooked up the scanner to download the codes on the vehicle. Vehicle had several codes for the brake system, Telematics communication, engine control module, power steering control module and Body control module. The service Manager stated that they would need to charge me $200 to diagnosis the problem. They would need to keep the truck there 3-5 days. I am waiting on their diagnosis to determine the problem but I believe there is a safety issue involved with this vehicle and the repairs should be addressed by the manufacturer before someone gets hurt.

Complete loss of power assist steering with multiple safety codes causing loss of vehicle control. Was able to pull over in parking lot to get vehicle off the road. Near impossible to steer when incident happened. Frightening experience. As other complaints have noted frame to body ground strap located behind passenger front tire severely corroded and causing loss of ground contact. No service center open so had to be towed home. Vehicle only has 27,000mi. This has been reported frequently and should be a safety recall as very dangerous.

This 2019 Silverado pickup truck lurched forward on 2 different occasions. The first time it lurched forward, it was in a parking lot and no damage was done to the truck or any other vehicle. The second time our 2019 Silverado pickup truck lurched forward I was turning around at a farm. The truck hit a wooden building on the farm and did damage to it and our truck did damage the front end of the truck to the tune of $3,474. If someone was in front of the truck, they would have been killed or seriously injured. We have been very careful with the truck ever since. We could pull it into our garage and it could lurch forward and go through the garage wall.

While traveling on the [XXX] at 70mph the truck started making a loud noise and started feeling like all tires were flat. Getting off the road the routors were very hot. Getting back on the interstate to get to an exit, a message appeared that said brake failure. There were no brakes when pedal was applied. It was towed to the Integrity Chevrolet in Chattanooga, Tn. A case was opened with General Motors #[XXX]. GMC reported to us that the truck which we bought with 5900 miles (driven by a salesman), had had the brakes reprogrammed 4 times which we were unaware of. They reprogrammed the brakes, put on new brake pads, milled the router and replaced the brake fluid, informing us this was needed, charging us $1210. GMC refused to pay because the dealership said it was normal wear and tear. Truck has 38,000 miles. Brake pads showed 62% front and 78% back life. We have emails as documentation. I was unable to upload but can forward if email address is provided. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). The contact stated this is the 5th time the brake system has been reprogrammed, (4xs before we purchased it unaware of this and on March 11th).

I started vehicle. Everything seemed fine. Drove 2 blocks and all eletricals started acting up. Lights flashing all warning lights went off. Service brakes, Service parking brake, service ECM, etc. Motor started to bog down and major knocking from engine. Took to GMC dealership. They found issues with lifters and had to replace all lifters and camshaft. Also replaced faulty brake sensor. Get truck back and oil cooler hose or line came off and was leaking oil. 1 week after repairs. Take back to dealership for repairs. 2 weeks later went to start truck all electronics went haywire, lights flashing, all warning lights start going off again. Truck will not start. Let sit for 15 mins. Try starting and no electrical power at all. Truck will not shift out of park. Major issue. Sounds to be a common issue with 2019 Trail Boss. Only has 40,000 miles.

Currently own a 2019 Chevrolet Silverado 1500 Texas Edition Z-71. Transmission continues to hard shift / lunge in forward and reverse. The transmission has popped so hard, on multiple occasions that I was convinced that someone had hit me from behind and had to pull over. The downshift is occasionally so hard that it that you jerk forward out of the seat. In October of 2022 the downshift at 15 mph made me lose control of my truck and utility trailer, sliding me into a small tree causing over two thousand dollars in damages. The suspension is also extremely shaky and any rough terrain makes the vehicle uncontrollable even at low speeds. I have almost had 3 additional accidents because of loss of control in rain and snow. The suspension is also noisy when you first drive with a grinding / rubbing sound. Vehicle has been in for service for these issues on more than one occasion and I have been told they cannot find anything wrong. I have had a transmission code in the past that eventually turned off. A quick internet search shows these all to be known issues and Chevrolet refuses to address of repair these major safety issues.

Started truck in morning and service brake assist was displayed. Called dealership and was told ok to drive probably just a brake pad sensor. We were on vacation so kept driving, drove around Colorado Springs brakes seemed different but ok. Proceeded to drive up pikes peak just past 10 mile mark instrument cluster light up and chiming. The dash had service engine light, traction control, and brake light on. Instrument said brake system failure 43mph top speed, service esc, service trailer brake system and service brake assist.Was not using brakes as was climbing mountain. Proceeded to pull over and called dealer again. Was informed can-??t really do anything as that far away and try disconnecting the battery. Did that and nothing changed. Proceeded to drive down mountain and contact local dealer. Drove truck in limp mode to dealership. The were able to get truck in and diagnosed internally leaking master cylinder. Master cylinder has to be replaced as it has failed. Truck has 63000 miles on it. This is a major safety item and should not of failed with this low of mileage.

Trailer brake service indication comes on constantly and cannot see speed use the radio or make a call. Already have changed the switch that they say is the problem, did not fix issues. Other mechanics on the internet are saying it's a wire harness between the switch and the module this needs to be replaced due to poor quality. We'll have a professional mechanic assess this but it looks like it's a common problem across the board. Please get GM to issue a recall on this because it becomes a safety issue, distraction and not able to read speed. Thanks

While I-??m driving the truck will start jolting and driving rough. When I looked at the dashboard it said that the parking break is on. This has occurred on several occasions now. I have never used my parking break in this truck because I live in an area that is pretty flat.
