WHEN HAVING MY OIL CHANGED AT A GARAGE WHILE THE VEHICLE WAS ON THE LIFT BOTH FRAME RAILS HAD SEVERE RUST DAMAGE. SINCE THIS IS WHAT GIVES THE UNIBODY FRAME IT'S STRENGTH, WHY DIDN'T GM ZINC COAT THEM OR APPLY RUST PROOFING? I LIVE IN SOUTHEAST MICHIGAN WHERE THEY USE SALT ON THE ROADS IN WINTER.

WHEN HAVING MY OIL CHANGED AT A GARAGE WHILE THE VEHICLE WAS ON THE LIFT BOTH FRAME RAILS HAD SEVERE RUST DAMAGE. SINCE THIS IS WHAT GIVES THE UNIBODY FRAME IT'S STRENGTH, WHY DIDN'T GM ZINC COAT THEM OR APPLY RUST PROOFING? I LIVE IN SOUTHEAST MICHIGAN WHERE THEY USE SALT ON THE ROADS IN WINTER. SEEING GM IS ALSO IN MICHIGAN YOU WOULD THINK THEY WOULD BE AWARE OF THIS AND ACT ACCORDINGLY? THE ONLY REASON I CAN THINK OF IS TO SAVE MONEY, INCREASE PROFITS, AT THE EXPENSE OF THE VEHICLE BEING SAFE FOR THE CONSUMER. I DON'T SEE DESIGNING THE FRAME RAILS TO LAST FOR 20-25 YEARS FOR SAFETY REASONS AS BEING UNREASONABLE.

WHEN IT'S COLD AND YOU START THE VEHICLE I GET A MESSAGE REDUCED ENGINE POWER. YOU HAVE TO IMMEDIATELY SHUT IT OFF. SOM ETIMES WHEN YOU ARE DRIVING DOWN THE ROAD AND IT IS WARMED UP IT WILL DO THIS AND YOU HAVE TO FIND A SAFE PLACE TO PULL OVER BECAUSE IF YOU TRY TO GIVE IT GAS IT WON'T GO ANYWAYS. I THINK IT IS A SAFETY HAZARD BECAUSE IT CAN HAPPEN WHEN YOU ARE GOING 70 MPH ON THE INTERSTATE AND CARS ARE RIGHT ON YOUR ASS. LUCKILY I WASN'T ON THE INTERSTATE BUT I WAS ON A HIGHWAY GOING 60MPH WHEN IT HAPPENED.
