I purchased my vehicle'2015 chevy tahoe lt on july 1, 2019 i have had intermittent glitches in the electrical system. the headlights, dash lights, and mylink touchscreen will completely black out and then come back on. however, when this happens the steering wheel locks up for a split second. this is happening while driving, at speeds over 50mph, during the night and day. it was suspected to be the alternator or battery, after replacing the alternator there was no change in the behavior. it continues to happen. the service stabilitrack warning will also pop up after the power is restored. this issue is very dangerous and after reading dozens of forums it's clear this is not an isolated incident. this has happened over and over at least 20 times since july 2019, randomly and completely unexpectedly.
I put on the brakes and the interior lights flicker it is distracting while driving at night. seems to happen while car is running on the cooler side or just starting. this has been happening since we purchased the vehicle. i have done some research and it seems that i am not the only 2015 chevy tahoe owner who is experiencing this issue.
Driver side seat buckle doesn't latch at all times. also all interior overhead lights 'disco lights' flicker when the brake pedal is pressed or the turn signal is used.
When turning on the brights on my 2015 chevytahoe the dash screen will flash on and off, as well as shut off the cruise control when on. in addition, the stabilitrak will flash an error message. in addition to all of this the headlights flash while driving. at night this is very scary and harmful. these electrical issues need to be corrected!

Tl* the contact owned a 2015 chevrolet tahoe. the contact stated that while driving at various speeds the vehicle engine would cease. the cause of the failure has not yet been determined the contact was left stranded in the middle of the road and expressed concerns for his safety. the contact indicated that previously, the dashboard gauges had suddenly shut off and on occasions, the vehicle would not immediately start. the vehicle was towed to herb chambers chevrolet (90 andover st. danvers ma 01923). the manufacturer was not notified. the failure mileage was 96,000 .

While driving on the highway at high speeds, 70-80 mph, steering became extremely difficult for brief periods. often times it was immediately following actuation of the automatic window switch. it was accompanied with a lot of the loss of electrical power, a flickering control panel, abs light, stab trak, brake assist, and park assist warnings. a/c would stop, radio would turn off, the dashboard would flicker, then i would have to acknowledge all of the warnings in order to clear the issue. steering was tough, though controllable, but i question the ability of a less experienced drive to be able to handle the same problem at those speeds. this has happened before at lower speeds, usually while backing up to park. at lower speeds the suv would cut off completely. at higher speeds, the stall was recoverable, very fortunate in this matter. unable to get the issue to repeat at the dealership and it is very inconsistent. usually resets itself once the car is turned off and restarted.
Heavy moisture is accumulating in the front left headlight with no cracks in the light. it is causing the left front turn signal to malfunction with a warning on our instrument panel. this causes a dangerous situation when when making left turns as the left turn signal is inoperative. chevrolet is not accepting ownership of the faulty design, or part, or system and wants us to assume responsibility for the quoted $1200 in repair costs just to replace one headlight assembly. the extended warranty we purchased also won't cover it. i'm finding out through research that this is a common problem on this vehicle. just over 50k miles on the vehicle! these should be recalled!
All of the dome lights in my tahoe flash when i brake or put on the left turn signal. a simple google search shows that this seems to be a fairly common problem with specifically the 2015 tahoe.
While driving at night when applying the brakes the truck will shut off .all power will cut off ( truck will cut offf, no lights , all power shuts off . i will pop the hood move the battery post it hi the battery area and the power comes back on
Vehicle randomly loses steering control and flashes warning lights. at times, xm radio will not play. at one time, vehicle shut off and would not resart for approximately 10 seconds. occasionally, the warning lights flash when making an adjustment like changing to bright lights or activating the turn signal. left turn signal disengages cruise when activated. gm has updated the software twice due to service over the above complaints. fixes problem for short amount of time.
On several occasions my care has given me a warning of stability rack issues and it will then just shut down. this has happened in the middle of turning into parking lots as well as backing into parking spots. i then have to roll down and up my driver side and passenger side windows before i can restart my vehicle.
