2017 BMW 3 Series Electrical System Problems

During normal street and highway driving operation, the whole console and digital warning systems shutdown causing safety issues while driving.

Unsure of the exact cause, appears to be the high voltage battery/electric drive function that is faulty. It is creating a hazardous condition causing the vehicle to propel itself forward while driving in traffic and almost hitting other vehicles on the roadway when the electric drive fails or it switches between battery and the engine. If it’s not propelling itself forward, it’s unexpectedly decreasing power and preventing the vehicle from driving after stopping for traffic, traffic signals and traffic signs. Increasing the risk for a rear-end collision. The electric drive is failing & rapidly switching between battery & engine multiple times in a short period. Likely increasing risk for a fire hazard. This is putting the driver & others on the roadway at risk due to increased collision and fire risks. Ferman BMW has recreated the issue. They advised it needed 2 new batteries, standard and the auxiliary battery. Those were replaced and the vehicle still is having issues. Six replaced 3 times. They now blame it on the high voltage batteries & their age. HV batteries are covered under warranty, yet Ferman BMW states they are not because there’s no fault code. Their position is the electric drive malfunction message is a notification & not a fault code. Despite duplicating the issues, having notice of the hazard they refuse to fix it. The message states “ Electric drive is temporarily restricted. You can continue driving. After cooling/heating of high-voltage battery full electric drive power will immediately be available.” A brief search will reveal many others with the same issue and some were successful in getting it handled under warranty. The car has been inspected by Ferman BMW 6 times. This is an ongoing issue with this model and a hazard to the driver, passengers and others on the roadways.

I received a warning on the dashboard that the tires needed inflating and that I should not drive the car over 80 miles per hour. When this happened the communication system on the car failed. I could not use the telephone or the direction feature. I do not know if other parts of the car also failed. When the tires were re inflated, these other features returned. This has happened twice. (In addition the tires needed reinflating on one or two other times.) BMW offers a courtesy service to reinflate the tires so that they don't maintain a record of the problem and they are unable to add a note to their service record to document the problem.

What component or system failed or malfunctioned, and is it available for inspection upon request? Coolant lines How was your safety or the safety of others put at risk? The car would state that it is overheating a month after oil change and fluids replaced Has the problem been reproduced or confirmed by a dealer or independent service center? Dealer confirmed that there is a coolant issue Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has been inspected by the dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Engine light, coolant low warning, overheat warning, I am also having issues with car start/stop controls. With my car at 58k miles on it I don’t think the auxiliary battery should be having issues like it does. I read that some starters could be the issue but there is no recall on my vehicle which is in the USA. I have only had the car for 5 months and have significant auxiliary battery issues which ping off a lot of different sensors. They are listed in the photo.

THE AUTOMATIC LIFTGATE WOULD CLOSE ALL OF A SUDDEN WHEN I'M REACHING FOR ITEM(S) DEEP IN THE CARGO AREA. I WAS TOLD BY THE DEALER THAT SINCE MY FEET ARE UNDER THE HANDS-FREE/ KICK SENSOR FOR THE AUTOMATIC LIFT GATE THAT THAT WOULD ACTIVATE IT. HOWEVER, THE LIFTGATE WOULD ALSO OPEN OR CLOSE WHEN I'M NOT UNDER THE SENSOR SUCH AS FILLING UP FOR GAS OR PUTTING THE CAR COVER ON. FORTUNATELY, THIS ONLY HAPPENS WHEN THE CAR IS STATIONARY. THIS PROBLEM HAS OCCURRED SINCE PURCHASE IN 2018, BUT DEALER SERVICE HAS NOT BEEN ABLE TO DUPLICATE THE SITUATION.

WHILE THE CAR WAS PLUGGED IN OVERNIGHT IN THE GARAGE, (IT IS A HYBRID), A TERRIBLE ODOR WAS RELEASED AND CARBON MONOXIDE WAS DETECTED. FIRE DEPARTMENT WAS CALLED TWICE (THIS OCCURRED TWO NIGHTS IN A ROW) AND DETECTED HIGH LEVELS OF CO FROM INSIDE THE CAR AND FROM THE HOOD. WE NEEDED TO EVACUATE THE HOUSE EACH TIME. GAS COMPANY AND PLUMBER CONFIRMED THERE WAS NO OTHER ISSUES IN GARAGE. UPON REMOVAL OF THE CAR, ISSUES NO LONGER PERSIST. BMW CANNOT FIND ANYTHING WRONG WITH THE CAR, BUT I REFUSE TO TAKE THE CAR BACK, GIVEN SAFETY FOR MY FAMILY. THE VEHICLE WAS PARKED, TURNED OFF, LOCKED, AND CHARGING OVERNIGHT.
