The vacuum in the braking system failed and would not stop the vehicle especially after going over 1500 rpm the vehicle would stop, but if you had to brake without being able to go above 1500rpm the brakes failed. You had yo put a lot of pressure on the brake pedal to slow it down and stop. When you have a hill to go down it could be very dangerous. Taking the vehicle on 11/15/22 to Kendall Chev I'm Marysville, WA. No warnings were given on brake problem. Since truck will not stop normally, any person, vehicle, bike, etc is in danger of being in front of truck because of brakes failing.

Trailer brake assist warning keeps going off at different times with no trailer attached. Quite annoying and unsafe distraction.

- Stevens Point, WI, USA

This is a 2015 Chevy Silverado, I continuously get a message reading "Service: Trailer Brake System". This error message would continuously chime every 5 seconds, no matter if I cleared the message with the check button on the steering wheel or left it on. This chime would override the radio, phone calls, turn signal chime and any other noises put out by the vehicle in addition to covering the digital speedometer readout. I have yet to take it to a dealership as today was the first repetitive issue lasting over 30 minutes. I first noticed this at random over the last 2 months, but these messages would stop after 2-5 minutes worth of chimes. I plan to take this to a dealer for inspection, but wanted to check for recalls/ report the issue before doing so.

Trailer brake system I have owned this Chevy Silverado 2015 since 2018 when I purchased it certified from a used car dealership in upstate New York. About one year into owning the vehicle I started to experience an alarm that was flash trailer brake system. This alarm would beep and flash in my center consul restricting me from sight distracting me from driving and is almost impossible to drive the car without distraction. I checked YouTube I called the manufacture I did so much to figure out what was going on and why this was happening considering I do not show any thing I did not understand why the trailer brake would cause such a problem considering I never told anything.After about three months of driving the car this trailer brake system alarm stopped. Now recently 2022 the trailer break system alarm is back and flashes nonstop and is relentless. I cannot listen to music I cannot hear my own self think the alarm is so loud and so distracting I would rather walk to the store then drive the truck I am forced to drive this truck because of the fact that I need to get to work but the safety hazards that are now limiting me and I am afraid this is going to cause a major accident or loss of life. I recently discovered that this is a manufacturers wire harness malfunction due to faulty wiring and a low-grade wire harness system. Before this gets any worse I need some sort of help. Knowing that it is impossible to fix without thousands of dollars being spent and finding a specific electrical auto technician to fix it it is nearly impossible to have this fixed Chevy refuses to even acknowledge there is a problem I need someone to please help me and the other Chevy Silverado owners to get this under recall so that these wire harnesses can be replaced please help us my name is [XXX] my address [XXX] [XXX] is my cell phone number INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

2015 Chevy Silverado, 62,300 miles. While driving at highway speeds. The air condition compessor locked up. Causing the engine to die and causing the loss of power steering and power brakes.

The vehicle is experiencing a low speed brake failure where the brakes either pulse like ABS brakes or there is no brake at all and you have to push hard to the floor to get brakes. I have seen some reviews that say this was a recall but I did not find anything on your site and I have not received a notice.

- Brecksville, OH, USA

Slow speed braking is severely affected upon engagement, such as backing out of my driveway, or maneuvering into a parking spot. The brake pedal will pulse as if the ABS system is activating, however, upon reaching/ keeping idle speed, the brake pedal will become very rigid and the pedal is very hard to compress downward. Once the vehicle is stopped, and power is applied again with the gas pedal, normal braking is restored.

- Somerset, OH, USA

At low speeds, like idle, brakes do not want to work. Very hard to press.
