ELECTRICAL SYSTEM, UNKNOWN OR OTHER
There is an issue with the radio head unit that causes a high pitched noise, even when the radio is off. It happens with anything connected to the radio, like the indicator, seatbelt warning, door ajar warning. The high pitch noise causes migraines and nausea in drivers and passengers. Issue has been ongoing for months. All 3 radio heads installed by dealer have emitted this sound. Dealer refuses to send in 3rd new unit. Relief from sound only happens when the fuse for the radio head unit is pulled. Attaching a picture of the sound frequency after opening the door, car not on.

SERVICE BRAKES
The trailer break service light is coming on. There is not a way to dismiss the sound and comes on every few seconds, it's very distracting a HUGE safety risk. I have contacted GMC Valencia California and they have have several vehicles with the same issue / hazard. This has apparently been going on for years yet GMC refuses to put a recall on the vehicles nor take action on correcting this on this critical issue. This is very upsetting and with all the complaints / concerns it appears nobody cares for the lives this defective issue could cause, especially when towing. Thank you.

Radiator is leaking antifreeze because of excessive thermocycles within the cooling system caused by excessive cycling of the thermostat. Vehicle leaking antifreeze causing environmental hazards and possible overheating causing vehicle to shut off. GM knows about this and posted a service bulletin but will not repair when out of warranty.

ENGINE, POWER TRAIN
2014-2018 Chevy and GMC's have a problem with cycling of the thermostat that causes stress fractures on the radiator leading to coolant leaks. Attached are GM bulletins on the 2014 and 2015 models. As one can see they have provided special coverage on the 2014 models to 5 years or 100000 miles for this problem.(Bulletin 15829) This is not true of the 2015 through 2018 like mine. Although they use similar verbiage in the bulletin P11513A and P11513F. It should be noted that Bulletin P11513A and F also applies to 2015 Cadillac Escalade Models, 2015 Chevrolet Suburban, Tahoe, 2015 GMC Sierra Denali, Yukon Models, Yukon Denali Models Equipped with 4.3L, 5.3L or 6.2L Engine (RPOs LV1, LV3, L83 or L86). ***Basically this is a safety hazard because when traveling highway speeds it puts car into reduced power mode and you can only drive very slow on highway or be stranded on side which is just as dangerous ***

STEERING, EXTERIOR LIGHTING
Both my tail lights have failed. Dealer wants insane amount of money for new ones, so I opened up the lights and there is an obvious design flaw in the lights, to me it seems intentional at worst, incompetent at best. I am an electrical engineer, and there is no reason they should put a friction connection in the LED power bar, it is a glaring design flaw. Also having steering assist issue at low speed which was an issue that was supposed to be fixed in a previous recall service, but it is still malfunctioning.

SERVICE BRAKES
Last week, the power brake assist began fading away intermittently at low speeds, and caught my wife off guard in a grocery store parking lot when she pulled into a parking space and the brakes were not available. She had to plant both feet on the brake pedal in a panic stop before crashing into the car parked in front of her, and has since never driven the vehicle. This is a danger, and is potentially life threatening.

POWER TRAIN
Transmission failure at 167,000 miles. Transmission failed during a 100 mile trip initially slipping and eventually would not engage. Vehicle traveled on I 26 and could have resulted in accident on this 80 mph interstate. This vehicle is typically driven by my wife. No warning and GM Onstar provided vehicle diagnostic check in days prior to failure with no issues. Technician advised this was the 3rd vehicle this month in his shop with 6L80e transmission failure and said they normally fail around 150,000 miles. This is a known failure on numerous general motors vehicles across the product line. Repair required replacement of 6l80e transmission with a factory rebuilt transmission. Cost $4,100.

STRUCTURE:BODY
Vehicle is kept inside in a garage in Pennsylvania with 53000 original miles. While driving the vehicle a heard a sound that sounded like plastic cracking, low and behold I watched a crack form beginning at the split between the upper dash panel and the larger dash and it continued over the instrument cluster. I also noticed another smaller crack in the panel surrounding the air bag, of which as also been recalled but no solution as of today. Upon researching further I find I am not alone, this is an obvious defect in either part material or assembly and should be covered by a recall. Dealer replacement for this will run around 1,000 dollars. I am worried that if I am involved in an accident not only do I have to worry about pieces of metal being propelled into a passenger now I also have to worry about plastic from a defective dash. Thank you for you attention to this matter.
