NHTSA Complaint #10393133 — 2010 LAND ROVER LR4

I HAVE HAD REPEATED FAILURES DRIVING MULTIPLE LR4 AND A RANGE ROVER SPORT (I OWN BOTH). IF WHILE DRIVING THE VEHICLE YOU LIGHTLY REST YOUR FOOT ON THE BRAKE PEDAL (FOR INSTANCE IN DRIVING IN CLOSE QUARTERS) THE CAR WILL ILLUMINATE MULTIPLE WANRING INDICATORS INCLUDING ENGINE FAILURE, BRAKE FAILURE, GEARBOX FAILURE, PARKING BRAKE FAILURE, ABS FAILURE, TRACTION CONTROL FAILURE, STABILITY CONTROL UNAVAILABLE AND CRUISE CONTROL UNAVAILABLE. GENERALLY WHEN THESE CONDITION OCCUR THESE SYSTEM WILL DEFAULT TO REDUCED FUNCTIONALITY MODES. THIS PROBLEM IS REPRODUCIBLE AND IS A KNOW ISSUE WITH THE DEALER AND LRNA. LAND ROVER HAS ACKNOWLEDGED THIS ISSUE AND HAS NO CURRENT FIX OR PLANNED FIX. ITS APPARENT CAUSE IS A TWO STAGE BRAKE SWITCH WHICH CAUSES A SOFTWARE FAULT WHEN ONLY ONE OF THE TWO SWITCHES IS ENGAGED. LAND ROVER CANNOT CONFIRM THAT THE FAILURE OF THESE SYSTEM DOES NOT COMPROMISE THE SAFETY OF THE CAR. AT THE LEAST THIS FRIGHTENS THE DRIVER WITH WHAT APPEARS TO BE A MASSIVE SYSTEMS FAILURE OR AT WORST COMPROMISES VIRTUALLY ALL THE ELECTRONIC SAFETY SYSTEMS OF THE CAR. THIS ISSUE SEEMS TO APPLY TO THE LR4, RANGE ROVER SPORT, RANGE ROVER AND JAGUAR MODELS THAT USE THE SAME ENGINE COMPUTER SOFTWARE AND BRAKE SWITCH. MY RESEARCH HAS SHOWN OTHER OWNERS HAVE EXPERIENCED SIMILAR ISSUES
