THE MERCEDES BENZ THOR MOTOR COACH SUDDENLY WENT LIMP (WOULDN'T GO HIGHER THAN FIRST GEAR OR FASTER THAN ABOUT 10-15 MPH). THE YELLOW ESP, ABS AND ASR/BAS INDICATOR LAMP LIT WHILE THE ENGINE WAS RUNNING, EVEN WHEN IT WAS STATIONARY. CRUISE CONTROL BECAME INACTIVE. THE COACH'S OPERATING MANUAL SUGGESTED TO NOT DRIVE THE VEHICLE AS IT COULD RESULT IN AN ACCIDENT. AFTER RESEARCHING MORE ON THE TOPIC, WE FOUND THAT IT'S A PROBLEM THAT MANY MERCEDES SPRINTERS HAVE AND MAY BE UNDER EXTENDED FEDERAL WARRANTY.

THE TRIMARK RV DOOR LOCK WITH DEAD BOLT BLACK, 60-1650 BROKE, LOCKING US OUT OF THE RV. HAD TO GET A STATE COP TO HELP US BREAK INTO THE MOTOR HOME. AFTER DOING SOME RESEARCH DISCOVERED THE BOLT IS MADE OF ZINC AND VERY PRONE TO BREAKAGE. I THINK THIS IS A SAFETY ISSUE AND TRIMARK SHOULD HAVE A RECALL ON THESE LOCKS.
