2018 BMW X3 Electrical System

Digital dashboard which show speed, RPM, fuel, temp and other important information randomly goes blank while driving. It will come back on by itself or after restarting the car. This has happened many times.

When the temperature is cold, the instrument cluster won’t turn on.

The sos antenna in our x3 had a leak around the seal due to a poor design. Over time the tcb got corroded and caused an sos system malfunction. I have researched other cases in which a malfunction had not popped up, but still replicated the same issues as with the warning. Part of the module is the automatic sos help, if one were to get into an accident and rely on this system not realizing it was faulty, it could result in much slower response times if said person were unable to access a phone able to call proper emergency response teams.

The trunk on the vehicle can be opened while on the freeway. If you bump the trunk open switch or key fob button the trunk will open even when the car is in motion leading to personal belongings being thrown all over the road. This is a massive issue that should have been caught and fixed immediately.

WHILE DRIVING AT 60 MPH THE ELECTRONIC DASHBOARD COMPLETELY SHUT OFF. IT RESTARTED ITSELF AFTER SOME 30 SECONDS. WHEN IT REAPPEARS IT DOES NOT SHOW CORRECT SPEED, IT STARTS AT 0 AND WORKS ITS WAY UP TO THE CORRECT SPEED. I HAVE BEEN UNABLE TO GET A PICTURE OF THE DASHBOARD AS IT HAS HAPPENED WHILE DRIVING AT SPEEDS THIS CAR HAD PREVIOUS DASHBOARD PROBLEMS WITH THE DASH SLIDING TO THE LEFT. THIS WAS BROUGHT TO THE DEALER FOR CORRECTION. THIS IS DIFFERENT. IT IS A MOMENTARY COMPLETE DASH FAILURE.

DIGITAL IMAGE OF SPEEDOMETER AND TACHOMETER NEEDLES SHIFTED TO THE LEFT MAKING IT IMPOSSIBLE TO ACCURATELY READ THE SPEED OF THE VEHICLE. CONSISTENT WHEN VEHICLE STATIONARY OR IN MOTION; NEEDLE POSITION WOULD CHANGE WHILE IN MOTION AND CHANGING SPEEDS BUT MAJORITY OF "NEEDLE" NOT VISIBLE. DID NOT RESET AFTER RESTARTING THE VEHICLE SEVERAL TIMES. DID RESET AFTER A FEW DAYS.

TL* THE CONTACT OWNS A 2018 BMW X3. THE CONTACT STATED THAT THE SPEEDOMETER DISPLAYED THE INCORRECT SPEED. THE DEALER (GAULT AUTO SPORT BMW, 2311 NORTH ST, ENDICOTT, NY 13760, (607) 748-9875) INFORMED THE CONTACT THAT THERE WAS NO REMEDY FOR THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 5,900.
