2015 Chevrolet Tahoe Exterior lighting Problems

The 2015 Chevrolet Tahoe seems to be known for thermostat failure. My thermostat gauge while driving would drop from 210 to 160 and stay pinned on 160 and the fans would turn on. I was told by an auto body shop that it seemed to be electric issues. I also had a wire under the car catch fire and the auto body shop said that is why my standing lights would not work in the rear but my brake lights would work. It’s very dangerous that the electrical failure caused a fire to start under the car. Then, I ran into another issue just this week where the vehicle has a cracked AC condenser and is slowly losing coolant. It’s a manufacturing issue because all of them seem to crack and we’re not made with a proper seal. Another electrical issue I have is when I turn the wheel all the way to the left or right, even when the key is in and engine is on, the engine will shut off. The car completely shuts off and then I have to turn the key to the off position and then it will turn right back on. The steering wheel is also losing power steering and gets very tight when I have to make a turn. The fuses for my radio are blown and when you put new ones in, it blows immediately and doesn’t turn on. I have MANY issues with this vehicle and it’s obviously a manufacturer issue. This is not ok for a vehicle to all around have such horrible electrical issues. I have had issues driving over a pothole and I lose my radio screen or my whole dash screen and then the dealer and auto body shops say the electrical work is too in depth for them.

I have not had a wreck but the fact that when you press the brake pedal the dome lights blink and when you turn on the left turn signal, the dome lights blink. If you hold down the brake like if you’re at a traffic light the dome lights blink continuously until you let off the brake. Now, during the day, that’s no big problem but at night it poses a serious safety risk. A bright light in your eyes while driving is blinding and a sudden bright light in the pitch black dark could lead to an accident. I called the dealer to ask about it and was told yeah, they knew about it and it would cost me like $550 to repair even though it was a defect that they readily acknowledge.

On several occasions at various speeds, both driving straight and turning, my 2015 Chevy Tahoe has turned off. During higher speeds the SUV will turn back on, instantly, by itself but during lower speeds and turning the car has to be manual turned back on by switching into neutral, pressing the break, and pushing the start button. The most recent time this has happened, it was dark outside and I was turning. I lost everything including my head and tail lights so it was hard for oncoming traffic to see me. I also almost hit someone coming in the other lane because I was unable to fully turn due to the loss of power steering. After this happens, I get many warning/action required messages across the dashboard but no check engine light or code have come up. I will be taking it to the dealer but since it does not happen every time the care is driven, I can only hope they can experience what happens.

Dome lights keep flickering. Not specific to any light. All of them flash sporadically. Looks like a camera flash at night. It is beyond distracting at night and the dealership could not find what is causing it to happen. It is making driving at night dangerous because it is distracting because it can sometimes flash non stop like a strobe light.

NOT LONG AFTER I PURCHASED MY TAHOE NEW I NOTICED MOISTURE IN THE HEADLIGHTS, MORE SO ON THE PASSENGER SIDE. I HAD THE VEHICLE BROUGHT IN FOR AN AC RECALL AND THE DEALER DIDN'T NOTICE OR FIX THE PROBLEM. AFTER THE WARRANTY EXPIRED I STARTED GETTING ACCUMULATING WATER IN THE LIGHT ASSEMBLY WHICH WOULD CORRODE THE BLINKER HOLDER MAKING IT INOPERABLE. SO I EITHER HAVE TO CHANGE THE BLINKER HOLDER OR REPLACE THE ENTIRE LIGHT ASSEMBLY. I FEEL LIKE THE DEALER SHOULD HAVE NOTICED THE ISSUE WHEN IT WAS IN THE SHOP FOR THE AC RECALL.

MY TAHOE SHOWED STABILITRAK ISSUES WHEN I FIRST BOUGHT IT A YEAR AGO. I RECEIVED A RECALL NOTICE AND TOOK IT INTO THE NEAREST DEALER. IT WAS OK FOR AWHILE BUT THE SAME PROBLEM STARTED AGAIN A MONTH AGO. THE TRUCK TURNS ON AND OFF FOR ABOUT 1 SECOND AS I'M PULLING INTO A PARKING SPACE. HOWEVER, NOW I'VE HAD ISSUES WHEN I TRY TO LOCK IT WITH THE FOB; IT DOES NOTHING. I HAVE BEEN STRANDED AT A BUSINESS BECAUSE IT WON'T TURN BACK ON AND I HAVE TO WAIT AWHILE AND TRY TO CRANK IT. IT COMES BACK ON BUT THIS HAS HAPPENED TO ME MORE THAN 3 TIMES. NOW, I WAS DRIVING TO WORK AND AS I PULLED INTO MY WORK GARAGE, EVERYTHING TURNED OFF COMPLETELY AND THIS TIME NOTHING CAME BACK ON. I HAD TO QUICKLY TURN THE IGNITION KEY TO THE OFF POSITION, THANKFULLY I HAD MY FOOT ON THE BRAKE AND I HAD TO TURN IT BACK ON AGAIN. I WAS WORRIED BECAUSE THIS IS IN THE DOWNTOWN AREA AND THIS IS A VERY BUSY CITY STREET IN THE MORNING HOURS. I WAS LUCKY IT TURNED BACK ON AT ALL. ANOTHER TIME, I COULD NOT START MY TRUCK WHEN I GOT OFF OF WORK AND I WAS STUCK ON THE 3RD FLOOR OF MY PARKING GARAGE. I AM CONCERNED THAT I'LL BE DRIVING AND ALL OF A SUDDEN THIS TAHOE WILL SHUT OFF WHILE I'M IN TRAFFIC. I HAVE TO TRAVEL 3 FREEWAYS TO GET TO WORK AND BACK HOME DURING HEAVY TRAFFIC, I'M WORRIED ABOUT MY SAFETY AND OTHERS AS WELL BECAUSE SINCE THIS IS AN ISSUE WHERE THE TRUCK TURNS OFF COMPLETELY, I WILL HAVE NO CONTROL ON GETTING HIT OR HITTING SOMEONE ELSE AT A HIGH RATE OF SPEED (65 MPH)

MY 2015 CHEVROLET TAHOE LTZ'S HEADLIGHTS HAVE DEVELOPED CONDENSATION INSIDE OF THEM. THE DRIVER SIDE LIGHT HAS AN INCH OF STANDING WATER IN IT AND NOW THE TURN SIGNAL AND LED RUNNING LIGHT NO LONGER WORK ON THAT SIDE. CHEVROLET SAID IT WILL COST OVER $2,000 TO REPLACE BOTH HEADLIGHTS. I KNOW SEVERAL OTHER TAHOE OWNERS THAT HAVE THE SAME PROBLEM AND OUR LOCAL POLICE DEPARTMENT HAS ALSO HAD TO REPLACE HEADLIGHTS IN SEVERAL OF THEIR PATROL TAHOES. CHEVY NEEDS TO ISSUE A RECALL ON THEIR DEFECTIVE PRODUCT!!!

THE FRONT LEFT HEADLIGHT IS IN EXCELLENT CONDITION BUT FILLS WITH CONDENSATION UPON WASHING THE VEHICLE AND DURING RAIN STORMS. WHEN DRIVING AT NIGHT UNDER THESE CONDITIONS VISIBILITY IS POOR. THIS IS A SAFETY HAZARD AND NEEDS TO BE RECTIFIED BY GM WITH A SAFETY RECALL.

WHILE THE VEHICLE IS IN MOTION, AND THE INTERIOR DOME LIGHTS ARE OFF, I PRESS THE BRAKE PEDAL, AND THE DOME LIGHTS FLICKER VERY INTENSELY FOR A HALF-SECOND. THIS FLICKERING ALSO HAPPENS WHEN THE LEFT TURN SIGNAL IS ACTIVATED. IT IS A VERY BRIGHT FLICKER AND COULD CAUSE AN ACCIDENT DUE TO MOMENTARY DISTRACTION OR LIGHT-BLINDING.

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.

THE INTERIOR LIGHTS FLICKER WHENEVER THE VEHICLE'S BRAKES OR LEFT BLINDER IS USED. THE FLICKERING CAUSES DISTRACTION FOR THE DRIVER AND PASSENGERS. FLICKERING HURTS EYES, IN ADDITION CAUSING HEADACHES AND POTENTIAL FOR SEIZURES. FLICKERING OCCURS WHEN THE VEHICLE IS IN MOTION AND WHEN THE BREAKS ARE USED AND/OR THE LEFT BLINKER IS TURNED ON. THIS IS ESPECIALLY DISRUPTIVE WITH INNER CITY DRIVING.

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 CONTROL PANEL. THIS IS DANGEROUS TO DRIVING WHEN MAKING LEFT TURNS WITH NO FRONT TURN SIGNAL AND WILL CAUSE AN ACCIDENT EVENTUALLY TO SOME OWNERS WHO CANNOT AFFORD TO GET IT FIXED. CHEVY WILL NOT TAKE OWNERSHIP OF FAULTY DESIGN, PART, OR SYSTEM AND WANTS OWNER OF CAR TO ASSUME RESPONSIBILITY FOR REPAIR COSTS WHICH ARE VERY HIGH ON THESE FAULTY PARTS. THE EXTENDED WARRANTY WE PURCHASED DOES NOT WANT TO PAY FOR REPAIR EITHER WHY SHOULD THE OWNER WHO HAS NO CONTROL OVER THE INSTALLATION OF DEFECTIVE SYSTEM HAVE TO PAY FOR IT ? PLEASE HELP SAVE LIVES FROM POTENTIAL CRASHES.
