Chevy Blazer has low milage. However, it still has several electrical issues radio at engine start goes to loudest point and car seats move backwards at awkward times which can cause an accident. Suspension very off guard, truck drifts to the sides while driving and makes an awkward sound when turning steering wheel. The complete break / steering system is off and may cause an accident if not properly take care right away. I have no money to do this big job. Please remediate.

TRANSMISSION COOLER LINES BETWEEN THE RADIATOR AND TRANSMISSION ARE CORRODED AND PITTED. THE LINES ARE INSTALLED OVER THE EXHAUST CATALYTIC CONVERTER. THERE IS TRANSMISSION FLUID LEAKING FROM THE LINES, WHICH IS DRIPPING ONTO HOT EXHAUST COMPONENTS AND BURNING, CREATING A FIRE HAZARD. THESE LINES APPEAR TO BE STAINLESS STEEL, WHICH SHOULDN'T BE CORRODING. THE LINES SHOULD NOT BE IN SUCH CLOSE PROXIMITY TO EXHAUST COMPONENTS. WHEN THE VEHICLE IS NOT RUNNING/IN MOTION, TRANSMISSION FLUID POOLS ON THE GROUND UNDER THE VEHICLE. IN MOTION, THE FLUID IS BEING BLOWN REARWARD, COATING THE UNDERCARRIAGE AND EXHAUST.

THE NEXT DAY THE BRAKE LIGHTS WORKED AGAIN, BUT REMAINED ON AFTER I SHUT OFF THE ENGINE. MY MECHANIC WAS ABLE TO DETERMINE THE PROBLEM WAS THE MULTIFUNCTION SWITCH ON THE STEERING COLUMN. THIS WAS A KNOWN ISSUE (GM RECALL NUMBER 01073) AND GM RECALLED A NUMBER OF THE SAME MAKE AND MODEL OF VEHICLES, BUT MY BLAZER'S VIN WAS NOT INCLUDED IN THE OFFICIAL RECALL.
