Exterior lighting

48 reports
“THE VEHICLE'S GAS TANK WON'T HOLD MUCH AND CLICKS AS IF FULL. ALSO, WHEN ON UNEVEN PAVEMENT OR GROUND, THE ⛽ GAS WARNING LIGHT COMES ON, EVEN AFTER GAS WAS JUST PUT IN. IN ADDITION, AT TIMES I SMELL A "BURNING ELECTRICAL" SMELL AND THE HEADLIGHTS GO OUT, THE BRIGHTS FAIL TO "CLICK" ON OR GOES OFF BY ITSELF. THE TURN SIGNAL LIGHTS HAVE TO BE TURNED MANUALLY TO BLINK. ALL TURN SIGNAL LIGHTS HAVE BEEN REPLACED MULTIPLE TIMES AND THIS DOES NOT FIX THE PROBLEM. THE BACK TURN SIGNALS WORK AND LIGHT UP, BUT NOT THE FRONT & BLINK AT A FASTER RATE. EVEN ONE SIDE HEADLIGHT ENGAGEMENT WAS REPLACED AND THE PROBLEMS STILL EXIST.”

Electrical system

24 reports1 crash
“HORN BUTTON IS PART OF AIR BAG. THE HORN BUTTON SHORTS OUT AND THE HORN BLOWS ALL THE TIME. HAVE TO REMOVE FUSE TO STOP HORN BLOWING. HAD TO REPLACE AIR BAG TO FIX. IN A FEW MONTHS THE PROBLEM REOCCURRED. ITS TOO EXPENSIVE TO REPLACE AIR BAGS SO I AM LEFT WITHOUT A HORN THIS IS A SAFETY ISSUE. CAN THE MANUFACTURER PROVIDE A FIX? THE INTERNET SHOWS THIS IS A VERY COMMON PROBLEM FOR A LOT OF GM CARS.”

“EVERY BUICK OWNER, I HAVE TALKED TO AT ABOUT 80,000 TO 100,000 MILES HAS TO REPLACE INTAKE MANIFOLD AND BOLTS. THIS IS ABOUT A $1200.00 JOB, GASKETS AND BOLTS SHOULD LAST A LOT LONGER. *TR”

“THE 2003 HAS A NUMBER OF ISSUES. 1. THE LIGHTS TURN OFF AT RANDOM IN THE DARK. THIS HAS HAPPENED ON NUMEROUS OCCASIONS. 2. THE BRAKES NEED TO BE REPLACED ROUGHLY EVERY 8 MONTHS. MY MECHANIC SAID THE BUICK CENTURY HAS BRAKES THAT ARE NOT ADEQUATE FOR THE WEIGHT OF THE CAR. COSTLY! 3. OIL SYSTEM LEAKS, COMPLETE BREAKDOWN. $1200 TO REPLACE THE SYSTEM. 4. THE DIALS ON THE TEMP CONTROL COME OFF. I AM TRADING THIS POS OFF BEFORE IT COSTS ME MORE MONEY! *TR”

Structure

“My vehicle was receiving a PA state required annual mechanical safety inspection by an ASE certified mechanic. I was informed that the "sway bar" which stabilizes the steering system had failed, and as a critical part of the steering operation, the vehicle could not pass a PA state mechanical safety inspection. I had the "sway bar" replaced with the GM re-designed part at considerable expense to pass the PA state safety inspection. The ASE certified mechanic advised me that he had replaced many mechanical failures like mine (broken lug ends) before GM changed the design to one that could withstand the application (a solid forging as opposed to a sheet metal fabrication). I wrote to the CEO of Buick/GM (see attached letter) to request an explanation as to why a known safety defect like the "sway bar" was not recalled when it was first discovered, resulting in a re-design of the "sway bar" for subsequent production models. I received a telephone response from the GM Executive Team, who called himself "Debbie", at 1.855.880.1500, extension 5917674, Reference Number [XXX], on 26 July 2023. "Debbie" refused to document GM's position on this issue in writing, and…”
