SERVICE BRAKES, ELECTRICAL SYSTEM
I keep getting a warning message "service trailer brake system". The warning may come on for a second or it may stay on for 10 to 15 minutes. It may do it once a month or 10 times in a 2 minute period. Whenever this happens I lose the electrical braking system on what I am towing. There is no set pattern or circumstance for when or how long it will happen. I was told if the alert is not on there is not a way to diagnose the problem and since I never know when it will happen I cannot schedule any type of diagnostic service. It does seem to happen more often when it is raining but has happened in perfect weather too. The warning has occurred both when I am towing and when I am not. I've done searches for possible causes and it seems to be a common problem. I regularly tow a 12,000 lb. fifth wheel RV with my family. I cannot afford to lose my ability to stop in a reasonable amount of time. I simply cannot do it when I lose my trailer braking system. The date below is the last incident.

VISIBILITY/WIPER
Both the outside mirrors are loose and will fold while driving. At night if I am not aware and it is dark the mirror fails to identify vehicles in the visibility area because they vibrate closed to the door from the driving air on the mirror. I will have to pull over and push the mirror back. I have brought it to the dealer and they say they all do it. It is normal. The issues has been confirmed by the dealer. It has been present on the car for about 1 year. The internet is filled with this safety complaint. They are starting to fold when you close the door.

SERVICE BRAKES
I was backing my boat into the water at a boat ramp and my brakes got very hard to push when I was backing into the water. I had to stand on the brakes to get it to stop, if my wife had been backing the truck in, it would have been in the lake. I see that there are no recalls on this vehicle. I bought it about four months ago and don't know the history of any recalls that have been done. I also had the transmission problem with the shimmy, and per the GM dealer flushed the fluid and the shimmy has all but disappeared. I am glad, because when I ask if it didn't repair it would the transmission be covered under warranty, he said no because of the mileage. These reasons are probably why the guy traded it in in the first place.

TIRES:SIDEWALL, TIRES
I noticed a sway in the vehicle while driving down the highway, bad enough to pull over and check the tires and suspension. Took truck to dealer where upon inspection I was told that the cause was the tires' sidewalls are not stiff enough and the tires try to follow the grooves in the road. The dealer recommended changing the tires but had to defer to General Motors who denied the tire change under warranty. GM informed me that this is a normal condition of the tires on roads that have grooves cut in and would not be covered under warranty. I explained that I do not feel safe towing a trailer behind this truck and was told that they could not replace the tires but offered me multiple options for my trouble including: Onstar, service voucher which cannot be used on tires, accessory voucher which cannot be used on tires, and a wheel and tire protection plan which would not cover the issue at hand. I declined all of the offers as my only concern is having a truck that is safe to tow a trailer behind and new tires are required in order for me to have that. The truck is designed to be able to tow a trailer and I am too concerned to tow behind my brand new truck because the truck would induce a sway into the trailer posing a significant safety risk to myself and other motorists on the road. If this is a known issue, which it seems to be, then General Motors should not include these tires on trucks sold in markets with grooved pavement to reduce the risk of accidents resulting in injury or even death. I shouldn't have to spend an additional $1200+ on new tires for a vehicle that was less than a month old when I took it into the dealership.

SERVICE BRAKES, STEERING
Driving at certain speeds the truck will just shut off while trying to turn or merge onto the highway. The electronic steering draws to much voltage on the vehicle and it just dies turning and braking after that is a very serious safety hazard and should be looked into I’m a mechanic myself and I’ve replaced grounds done everything I can and still nothing has fixed the issue

STEERING
We have been told that the recall #17V414 has been completed on our vehicle. However, we have only owned this pickup a little over a year and now the power steering has gone out again. it is throwing a code U0131 which says it is lost communication with power steering control module. We have been told that the power steering module needs to be replaced. I would like to delve into how many people have had to replace this (which is a very EXPENSIVE repair). I truly feel this is still a defect and GMC should own this problem. Thank you for your time.
