SUSPENSION
The front left frame that the wheel and suspension bolt onto is in advanced rust stages. It is being considered unsafe to drive although the right side is still considered safe. Common issue from what I have heard. Took car in to replace the starter and shop doesnwant to work on it. We cannot afford a new vehicle because of a knkwn weakness in the frame work

AIR BAGS
The front impact sensor, also known as a crash sensor (part # 10370150), is no longer functional. It detects rapid vehicle deceleration during a frontal collision and sends an immediate signal to the Airbag Control Unit (ACU) to deploy airbags. Located behind the front bumper or on the radiator support, these sensors measure impact severity to ensure airbags deploy only when necessary. This part is no longer available from GM or any other aftermarket distributor. It is a critical part for any occupants in a crash. I am just one of many people who cannot make safety corrections.

STRUCTURE:BODY, UNKNOWN OR OTHER
I HAD A CRACK IN THE WINDSHIELD AND WHEN THEY REPLACED IT THE TECHNICIAN SAID IT WAS SO RUSTED FROM THE INSIDE THAT IF ANYTHING HAPPENED AGAIN THEY WOULD NOT REPLACE IT HE HAD TO REALLY DO SOME WORK AROUNDS HE SAID TO EVEN REPLACE THIS ONE. THAT MAKES ME FEEL THAT THIS IS A REAL SAFETY ISSUE IF WE WERE TO GET IN A SERIOUS ACCIDENT. THERE IS NO RUST ON THE OUTSIDE AROUND THE WINDSHIELD AT ALL. SO I WAS VERY SURPRISED WHEN THE TECHNICIAN TOLD ME THAT.

SERVICE BRAKES
BRAKES FAILED "COMPLETELY", WITH NO WARNING. NO "WARNING LIGHT" ON THE INSTRUMENT PANEL WHILE DRIVING ON A PUBLIC ROAD IN THE COUNTY. ALL OF A SUDDEN ABSOLUTELY NO BRAKES. HAD RECENTLY HAULED A CAR ON A TRAILER FROM EMPORIA, KANSAS. WAS PREPARING TO HAUL CALVES TO THE SALE BARN. NOW THAT WOULD HAVE BEEN A TOTAL DISASTER. UPON INSPECTION, THE BRAKE LINES ARE SO RUSTED, THAT PINCHING OFF THE LINE RESULTED IN A RUPTURE IN ANOTHER LOCATION. I WAS TRYING TO GET SOME BRAKING ACTION, SO I COULD DRIVE IT TO A REPAIR SHOP. I'LL HAVE TO HAUL IT. *TR

SERVICE BRAKES
BRAKE LINES BUSTED. THIS IS A VERY SERIOUS PROBLEM BECAUSE I WAS HAULING A LOAD AND GOT EXTREMELY EXTREMELY LUCKY THAT IT BUSTED AS I WAS PULLING IN DRIVEWAY. I WAS PULLING A LOADED TRAILER WITH NO BRAKES. THIS IS A VERY COMMON ISSUE WITH THE 2005 AND 2006 2500 TRUCKS. I CAN NAME 6 VEHICLES I KNOW OF IN THE PAST 6 MONTHS THAT THIS HAS HAPPENED TOO. MECHANIC SAYS IT'S A VERY SERIOUS AND COMMON ISSUE THAT GM SHOULD BE RECALLING. IF I WOULD HAVE BEEN AT A STOPLIGHT IT WOULD HAVE BEEN BAD. CHEAP MATERIALS IS THE PROBLEM WITH THESE BRAKE LINES. 2006 YEAR MODEL IS MINE.
