Radio changing channels by itself, menus changing by itself, instrument screen changing from info to audio by itself, calls being made to last number by itself, navigation image jumping to different areas by itself not showing the vehicles location, causing confusion when trying to get directions. All this is very distracting for driver and could possibly cause distraction enough to cause an accident.

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.

Radio is malfunctioning. Radio would randomly change channels. Than the radio would have a line in the bottom of the screen. Than the half the radio just quit. Now the radio or phone calls does not work at all. I do not have access to hands free calls. I believe there is a recall on the same stereo for the 2019 models. It has not been inspected but is available for inspection. No warnings lights prior to the radio not working. I have a video but I do not know how to attach.

I have a 2018 Chevy Silverado 4WD, Crew Cab truck purchased brand new in 2018. Over the last year, I have had intermittent, and relentless chiming of the "Service Trailer Brake System". This occurs any time, completely randomly during normal, everyday driving and while NOT towing. it is horrendously distracting, and won't stop once it starts, even after clearing the message, it will continue to chime again every 1-2 minutes until I park the truck and turn off the engine. I have taken it to my local Chevy dealer, they can't find anything wrong with my truck. I have checked fuses, switches and relays, to no avail. I see this is not a "once-off" problem, it would appear 10s of thousands of consumers have had the same issue posted about blogs, YouTube and more around the internet since at least model year 2017. This is a complete safety hazard and unacceptable! The chime is a distraction and prevents other vehicle safety features from being usable when it is going off. In addition, I imagine if I WERE towing, that means my braking system would be rendered unusable. That doesn't seem acceptable and there should have been a recall on this already based on my vast research. I am angered that this keeps happening even under normal driving conditions, and it is a defect of the trailer wire harness system, not something any vehicle owner has done, not due to abuse, or even normal wear and tear. I am angered that even my dealer can't find and fix the problem. However, it should not be my responsibility since this is a clear and obvious defect amongst nearly 100,000 similar model vehicles. I do not feel this is safe in any way and there needs to be a remedy "recall" performed so that other owners and myself can get this taken care of once and for all. Thank you.

The electrical power steering failed on my way home as I turned in to my street my steering became very hard to control nearly causing me to crash into a neighbors vehicle. This is the second time my electrical power steering has failed. About a year ago the original electrical power steering went out and a new one was purchased from a dealer ship and installed by a automotive company. Here we are a year later and it has gone out again but this time almost causing me to crash during a turn into my street. NO WARNING to me at all that my power steering was about to go out. Yes. My 2018 Silverado truck is available if an inspection request is asked of me.

At a low speeds while taking a turn, the electrical system clicks off and then clicks back on after about a second. Im able to see the voltage drop while taking the turn.
