Headlight assembly leaks and retains significant amounts of water resembling a half filled fish tank. This causes the bulbs to burn out or corrode the light power supply leaving you with no headlights! This is a very common problem across many GM platforms. I am surprised the Government regulators have allowed a safety problem this wide spread and known to continue unaddressed.

DRIVING TODAY IN SNOW, INCREASED ELECTRICAL DEMAND ON VEHICLE WHILE ACCELERATING. SMELLED BURNING WIRES AND ALL DASH LIGHTS FLICKERED THEN DIED. ENGINE TURNED OFF AND HAD TO BE RESTARTED WITH THE PUSH BUTTON. HAPPENED WITHIN 30 MINUTES LATER WHILE ACCELERATING ONTO A MAIN ROAD WITH TRAFFIC, LOST CONTROL OF VEHICLE AND HAD TO FORCE THE STEERING WHEEL TO TURN THE VEHICLE OFF THE ROAD TO AVOID BEING HIT BY ONCOMING TRAFFIC.

PURCHASED A 2015 SUBURBAN NEW FROM JIM ELLIS CHEVROLET. AT ABOUT YEAR 3 OF OWNERSHIP, JUST AFTER WARRANTY EXPIRATION, I NOTICED MOISTURE IN DRIVERS SIDE HEADLIGHT ASSEMBLY. ABOUT A YEAR LATER THE BLINKER STOPPED WORKING. THE ONLY WAY TO REPAIR IT IS TO INSTALL AN ENTIRE NEW ASSEMBLY. THE PART IS $1,200 ALONE. THE IS NOT A WARRANTY ISSUE, BUT A DEFECT THAT CHEVY WILL NOT ADDRESS OR ADMIT. IT IS ALSO A MAJOR SAFETY ISSUE. ADDITIONALLY, THE PAINT ON THE HOOD AND ROOF STARTED FAILING AT ABOUT YEAR 4. AGAIN, ANOTHER DEFECT. CHEVROLET WILL NOT ADDRESS EITHER OF THEM. ONE IS A SAFETY ISSUE, THE OTHER COSMETIC. VERY FRUSTRATED.

STATE REJECTS VEHICLE CITING MOISTURE INSIDE A SEALED HEADLAMP ASSEMBLY IS A SAFETY HAZARD. THOUSANDS OF COMPLAINTS POSTED ONLINE. GM/CHEVROLET ADMITS THE SEALED ASSEMBLIES ARE DEFECTIVE HOWEVER THEY DO NOT OFFER ANY ASSISTANCE WHATSOEVER REGARDING REPLACEMENT OF THE DEFECTIVE EQUIPMENT AND FURTHER STATING THEY CANNOT BE REPAIRED. DEALER HAS QUOTED A PRICE OF UP TO $1,400 TO REPLACE THE HEADLAMP ASSEMBLY ON MY VEHICLE. THIS ISSUE FIRST APPEARED WITH LESS THAN 40,000 MILES ON THE VEHICLE. THE MOISTURE ACCUMULATION CAN INCREASE OR DECREASE WITH RAIN OR OTHER ATMOSPHERIC CONDITIONS. THE ELECTRICAL CONTACTS WITHIN THE HOUSING OF THE SEALED LENSES RUST CAUSING THE LAMPS AND TURN SIGNALS TO INTERMITTENTLY GO ON AND OFF AND FAIL ALTOGETHER. ONCE FAILED, ATTEMPTS TO REPLACE THE BULBS HAVE BEEN UNSUCCESSFUL DUE TO THE OXIDATION AND/OR RUST ACCUMULATION ON THE LENS HOUSING CONTACT POINTS.

THE HEADLAMPS DO NOT PROVIDE SUFFICIENT LIGHT OUTPUT TO SAFELY OPERATE THE VEHICLE AT NIGHT. IT IS VERY EASY TO OVER DRIVE THE VEHICLE HEADLAMPS AND THE BRIGHT LIGHTS DO NOT PROVIDE ENOUGH INCREASE IN LIGHT OUTPUT TO ADDRESS THE ISSUE. I DO NOT FEEL SAFE OPERATING THIS VEHICLE AT NIGHT IN ANY REDUCED LIGHT CONDITION.

ESPECIALLY AT NIGHT, THE "WELCOME LIGHTS/REVERSE LIGHTS" OF A CHEVROLET SUBURBAN CONFUSE ME BECAUSE I THINK THAT PERSON'S VEHICLE IS BACKING UP. THIS CAUSES ME TO EITHER HESITATE OR AT WORST, PANIC IF I THINK THEY ARE ABOUT TO BACK INTO ME. THE PHOTO ATTACHED IS OF A DIFFERENT GM VEHICLE, THE GMC TERRAIN, BUT THE APPEARANCE IS THE SAME.
