2016 Bmw X5 Electrical Problems

Your 2016 BMW X5 hybrid won't accept a charge from any charging source, even after the high-voltage battery was replaced a year ago. You've also experienced warning messages about drivetrain and start/stop malfunctions, and the vehicle suddenly lost all power while driving on the highway at normal speeds—a dangerous situation in traffic. The underlying cause remains unknown, but it likely involves the hybrid control system, charging module, or related electrical components.

Your vehicle experienced drivetrain warning messages starting in September 2023, which your BMW dealer didn't properly diagnose and told you to keep driving. After a recent recall was issued for the electric water pump, it became clear that the pump was short-circuiting and causing electrical instability. This electrical problem has now permanently damaged your high-voltage battery's internal circuitry, leaving your vehicle unable to run. The repair will likely require battery diagnostics, removal, and possible replacement of the battery unit.

Water is leaking into your vehicle through the sunroof drain system and causing multiple safety systems to fail, including ABS brakes, stability control, collision warning, and airbags. You may see warning lights for these systems, experience loss of warning sounds, or notice electrical modules shutting down unexpectedly. This water intrusion appears to be caused by a design issue where the sunroof drains route water directly toward critical electrical components. The fix will likely involve inspecting and clearing the sunroof drain system, then diagnosing and repairing the affected electrical modules and safety system components.

Your water pump has a defect that's causing an electrical short circuit, which is disrupting your temperature sensor and other nearby electrical components. This short circuit is also causing an oil leak that's putting strain on your engine and turbo system. The combination of the faulty water pump and failed temperature sensor allowed your engine to overheat without warning, which has damaged your turbocharger seals, catalytic converter, and caused dangerous oil leaks throughout the turbo system. Fixing this will likely require replacing the water pump, temperature sensor, and possibly the turbocharger and related seals.

The electronic A/C compressor destroys itself internally on BMW hybrid and electric vehicles and should be considered defective. The A/C compressor is used to cool the cabin as well as the high voltage battery packs, and is considered an emissions component warranties for 7 years or 70,000 miles. Without a functioning A/C system the vehicle cannot charge or use the high voltage batteries. If the electric A/C compressor fails it could cause the high voltage battery system to overheat and risk of fire. I just had it replaced at 75,508 miles before it completely failed and there are plenty of other owners of BMW hybrid or electric vehicles experiencing the same.

Service Repair light is on indicating there is an issue but when you go to check there is no issue showing. I checked into the BMW service In Southampton with a complaint that the time on the dashboard wasn’t synching for daylight time savings. They said they’ll troubleshoot it. They did a hard reset with the battery and gave me the car back with service light on which wasn’t on when I drove into the service. I had the car serviced for 60k miles and they said this is a typical issue with 2016 BMW with electrical malfunction and it would cost anywhere from $200-$2500 to fix it. Now I am unable to get alerts on my vehicle. This is a big safety issue for me and my family as well as other vehicles on the road if anything goes wrong with the car, I won’t know what is the issue.

BMW NA is aware of this problem with the sunroof leaking water on the dashboard and damaging the electrical of the car. BMW NA is colluding with the dealers to inform customers they are clogged to charge them money for a clog that is non existent. The sun roof are not clogged as BMW NA and the dealers are saying I have video of the unclogged drain tubes and have caught the dealers all lying that they are clogged. I have video of this and can reproduce this collusion again again with the dealers lying.

Auxiliary cooling fan failed but engine light did not turn on causing EME fault. Cooling fan had to be replaced and overheated my engine.

Since 12v battery is down towing truck driver tried to jump start the car, there is no way to move the car, he failed to start car so move manually for towing to BMW service center. they reported EME(controller computer) Board damage, and BMW guessed jump start could damage, so insurance appraiser came to review and rejected this because BMW said there is no way to prove this, and then they charged EME B/D that is very expensive($9500) this is second time 12v Battery fail, it always make additional problem and make the car be unstable, I think this is design electrical issue

MY 2016 BMW X5 E40 STALLED AND LOST ALL PROPULSION POWER MULTIPLE TIMES WHILE DRIVING IN TRAFFIC, THE FIRST TIME AT ABOUT 40 MPH AND THE SUBSEQUENT TIMES AT AROUND 25 MPH, FORCING ME TO DRIVE THE CAR ONTO THE SHOULDER AND TRY TO RESTART IT. THERE WAS NO INDICATION OF ANY KIND AND NO WARNING LIGHT GIVEN PRIOR TO THE STALLS, IT SIMPLY JUST LOST ALL PROPULSION POWER. WE WERE TRAVELING UPHILL ON A BUSY HIGHWAY IN A CONSTRUCTION ZONE AND WERE FORTUNATE TO NOT BE IN AN ACCIDENT. AFTER THE STALL A WARNING INDICATOR MESSAGE INDICATED THAT THE AUTOMATIC START/STOP MALFUNCTIONED. THE CAR WILL EVENTUALLY RESTART AFTER ABOUT 5 MINUTES WITHOUT ANY WARNING INDICATOR AT ALL, AND THE PROBLEM WILL RANDOMLY REPEAT ITSELF WITHOUT WARNING. PROPULSION DOESN'T SLOWLY STOP, IT CUTS OUT COMPLETELY WITH NO WARNING. THE BMW SERVICE DEPARTMENT HAS INDICATED THAT THERE WAS A FAILURE INTERNAL TO THE TRANSMISSION. THIS CAR IS 5 YEARS OLD AND HAS 89,000 MILES ON IT.

WHILE DRIVING, ALL OF SUDDEN, DASHBOARD BECOMES BLANK. I BROUGHT THIS POINT TO BMW BELLEVUE DEALER. IT WAS CONFIRMED THAT THERE WAS NO ISSUE IDENTIFIED. HOWEVER, IT OCCURRED A COUPLE OF TIMES IN A YEAR. SINCE I WAS DRIVING 35-SPEED LIMIT ROAD, I PULLED THE VEHICLE AND STOPPED THE ENGINER AND THEN RESTART. THE ISSUE DISAPPREAD. I'M NOT SURE WHAT WOULD BE THE CONSEQUENCES OF IT WHEN I'M DRIVING AT HIGHWAYS OR AT HIGH SPEED.
