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.

THE BRAUN CORPORATION HAS NOTIFIED NHTSA ABOUT A DEFECT IN CERTAIN MODEL YEAR 2005-2008 GENERAL MOTORS MOBILITY CONVERSION, HANDICAPPED ACCESSIBLE LOW FLOOR MINIVANS. DURING CONVERSION, THE DRIVER OR PASSENGER SIDE TRAILING ARM MODIFICATION MAY NOT HAVE BEEN ADEQUATELY WELDED.
Consequence & remedy
Consequence: A SQUEAKING OR CLUNKING NOISE MAY DEVELOP. THE TRAILING ARM BUSHINGS MAY PREMATURELY WEAR AND THE TRAILING ARM MAY FRACTURE OR SEPARATE, ALLOWING THE REAR AXLE TO BECOME PARTIALLY SEPARATED FROM THE CHASSIS INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT AND WILL HAVE A SUPPLY OF RETROFIT PARTS AVAILABLE TO REMEDY THE VEHICLES FREE OF CHARGE. THE SAFETY RECALL BEGAN ON JUNE 4, 2010. OWNERS MAY CONTACT BRAUN AT 1-800-488-0359.
CERTAIN TRUCKS AND SPORT UTILITY VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 110, "TIRE SELECTION AND RIMS." THESE VEHICLES WERE SHIPPED WITH TIRE AND LOADING INFORMATION LABELS LISTING AN INACCCURATE VEHICLE CAPACITY WEIGHT.
Consequence & remedy
Consequence: A MISPRINTED LABEL COULD LEAD TO IMPROPER VEHICLE LOADING SPECIFICATIONS OR TIRE INFLATION WHICH COULD RESULT IN A TIRE FAILURE, INCREASING THE RISK OF A CRASH.
Remedy: OWNERS WILL BE PROVIDED WITH CORRECTED LABELS AND INSTALLATION INSTRUCTIONS. AT THE CUSTOMER'S OPTION, A DEALER CAN INSTALL THE LABEL FOR THEM. THE RECALL BEGAN ON MARCH 31, 2006. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, HUMMER AT 1-800-732-5493, PONTIAC AT 1-800-620-7668, SATURN AT 1-800-972-8876, OR ISUZU AT 1-800-255-6727.
