While driving the children to school making a Right turn in the school grounds. The Tahoe completely shut down and restarted. In the 10 seconds it was down I was unable to steer the vehicle and there was absolutely no power. When the vehicle restarted itself the "service trailer brake system", "Service stabilitrac" message come over the display. I immediately took it to the Sun Auto who recently replaced the AC compressor, they kept the vehicle for one day and part of another and they could not find any issues. It seems as if there is battery drainage and this has been inspected by North Side Chevrolet and they have been There are no service indicators and or messages. This is the second time it has done this to me and I am concerned for one my life, the five year old twins I drive everyday and any other people that could potentially be harmed by such a terrifying shut down. Imagine if I am on the highway driving to my job at the hospital and this happens.

I purchased a Certified pre-owned Chevy Tahoe, in 2017, for the past year to as of 2/18/2022, the Service Trailer Brake has been chiming. It isn’t continuous majority of the time, but I know it isn’t right and often alarms me when it does chime. I do not tow trailers behind my vehicle at all. I drive to work and home, take kids to school and sporting events. .I would like to know if this has or when will this be recalled? Obviously something is setting it off??

Trailer brake system error keeps showing. And not towing anything or using trailer brakes. Incredibly annoying

The trailer brake warning repeatedly alerts - even when not towing a vehicle or in use. This is distracting and has been for some time.

VEHICLE LOOSES POWER WHILE DRIVING FOR A SHORT PERIOD OF TIME. STARTS WITH WARNING DASH LIGHTS ACTIVING (ABS, GRADE BRAKE ASSIST) LOSS OF RADIO AND THEN THE TRUCK CUTS OFF, YET RESETS/RESTARTS ITSELF IMMEDIATELY.

Power Steering went out after being recalled in 2018.

There is a trailer brake warning that comes up, sometimes 10 times in a single mile of driving on the freeway. It beeps very loud and I cannot hear anything else. It is distracting to drive and I am unable to shut it off, I can only dismiss. I am now not sure if I can tow with my Tahoe because I fear there is something wrong with the trailer brake system. It is loud enough that if something else was wrong, I may not be able to hear it happening with the warning sound going off so often. I don't know exactly what is going on but my best guess is that it is either with the wiring, as this happens when I am not towing, or there is a sensor of some sort that is faulty. In any case, I don't think it is safe to tow because of potential hazards of the trailer brakes not working, or even worse, the trailer brakes locking up and me causing an accident.

Trailer brake system warning light keeps coming on, over 64 times in less then a 2 hour period, and I"m not even towing or using the trailer brake. It's very annoying, loud and can cause a crash as you immediately look down to see why the beeps are coming for

INTERIOR LIGHTS BLINK WHEN BRAKES ARE TAPPED AND WHEN USING LEFT TURN SIGNAL. HAS BEEN HAPPENING FOR 2.5 YEARS AND I NOTIFIED THE DEALERSHIP BUT REPAIR WOULD HAVE BEEN MY COST.

BOTH TAIL LIGHTS HAVE STOPPED WORKING AT THE SAME TIME. NOT A FUSE, IT'S A MALFUNCTION WITHIN THE LIGHT ITSELF.

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.

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

AND 2015 CHEVROLET TAHOE AND SUBURBAN VEHICLES EQUIPPED WITH A BASE RADIO AND AN INTERNAL AMPLIFIER. THE RADIOS IN THE AFFECTED VEHICLES MAY BECOME INOPERATIVE, AND AS A RESULT, THERE WOULD BE NO AUDIBLE CHIME TO NOTIFY THE DRIVER IF THE DOOR IS OPENED WITH THE KEY IN THE IGNITION OR NO AUDIBLE SEAT BELT WARNING INDICATING THE SEAT BELTS WERE NOT BUCKLED. AS SUCH, THESE VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD (FMVSS) NUMBERS 114, "THEFT PROTECTION AND ROLLAWAY PREVENTION," AND 208, "OCCUPANT CRASH PROTECTION."

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!
