2014 LAND ROVER LR4 Electrical System Problems

Communication error with system. This controls all functions from braking to cameras to suspension and audio/phone. Research shows that this is a habitual issue on almost all Land Rover models with no fix except to replace entire infotainment center which parts only range from 3-6k. Something needed to be done. This is supposed to be a high end vehicle. There are so many blogs with the same issue with no fix

AN AIRBAG MALFUNCTION LIGHT ILLUMINATED ON MY DASH TODAY. I SCANNED THE CAR FOR STORED FAULTS AND FOUND SEVERAL, BUT ONE IN PARTICULAR WAS FOR THE PASSENGER FRONTAL AIRBAG/SEAT. THE FAULT CODE SAID THERE WAS IMPROPER SERIAL DATA VALUES RECEIVED. THE CAR HAS JUST CROSSED OVER 50,000 MILES WITHIN THE LAST MONTH, HOWEVER IT IS STILL WITHIN 4 YEARS OF PURCHASE. SINCE THE MILEAGE IS OVER 50,000 MILES, I WAS TOLD BY DEALERSHIP THERE IS NO WARRANTY LEFT FOR THE AIRBAGS. SINCE THIS IS A MAJOR SAFETY FEATURE, I BELIEVE THIS SHOULD BE REPAIRED AT MANUFACTURER'S EXPENSE. THE PASSENGER SIDE DOOR LOCK ALSO FAILED AT THE SAME TIME. I HAVE ATTEMPTED TO RESOLVE THE ISSUE BY OPENING AND CLOSING THE DOOR, ADJUSTING THE SEAT POSITION AND FASTENING AND UNFASTENING THE PASSENGER SEAT BELT BUT THE LIGHT STILL REMAINS ON.
