This BMW vehicle's odometer readings are inconsistent and inaccurate resulting in overage of mileage for lessee. This cars BMW tires were not verifiable to be from BMW and tires subsequently failed within 15,000 miles. No entity at BMW, not the dealership, not the sales, not BMW Financial Services or BMW of North America LLC could provide any information regarding the original tires or provide any warranty information regarding the tires - this impact mileage efficiency, miles per gallon and is a way to game the systems. BMW front sensors on act erratically sometimes working and sometimes going off without anything present, during rain/snow sensors would constantly go off for no reason. Issues have been raised through certified mail to BMW and all have been ignored. There is no accountability regarding the tires with no warranty that fail, inaccurate odometer readings, car sensors and we request an investigation into these three matters.

On 5/22/24 had a catastrophic failure of the Electric Motor Electronics and 12v Battery. I have requested that the BMW Serice Assistant provide me with all affected parts for inspection. Shutdown of the vehicle high voltage system could result in a crash. When this part fails along with the 12v battery you lose control of all vehicle electronics (steering, braking, electrical power, and propulsion). Yes, there was a previous voluntary recall campaign 19V-599s Service Information Bulletin (Revision 2) which replaced SI B12 27 19 dated October 2019 by BMW for this device. The vehicle and component has been inspected by the Richmond BMW Service Technician. I started to experience problems with the vehicle in late April and took it in for servicing and repair in early May. I was told that the problem was a computer programming recall that was fixed.

While I was driving down the highway, sunroof has exploded without any apparent reason. I really didn’t realize what had happened at first, all I heard was a loud bang which could’ve lead to distraction and cause an accident. Luckily it wasn’t the case for me.

I brought the vehicle to BMW dealership, by the time I got there there was an apparent hole in the sunroof, they inspected it and saying it happened because something making contact with sunroof but when I asked for a proof for their claim they told me there is no physical evidence to provide.

Message on Console - " Passenger Restraint system malfunction ". Took vehicle in for Repair; BMW Dealership "thinks" it may be a wiring harness electrical short. They evidently need to discuss problem with BMW Corporate to figure out to properly diagnose problem and how to repair. My husband and I are very concerned about driving this car even after it may be "so called" repaired. We are concerned that if an accident does occur, and one or more of the airbags do not deploy; there may be serious injury or death to myself, my husband, grandkids, or other passengers.

Engine Wiring is made of Soy products with attracts Rodents to feed and destroy the wiring. When this occurs it puts the driver ad passengers in danger because certain functions such as brake light, Headlights and windshield wipers may not work properly. This is becasue when the wiring is compromised , circuits are broken which causes the vehicle's systems connected to that circuit to partially or completely fail, Rending a vehicle partially or completely inoperable. The vehicle was inspected the the BMW dealership service center and they confirmed it was rodent damage . Geico insurance also inspected the vehicle. The vehicle started to restrict engine performance and the Engine service light came on stating there was a Drive Tran malfunction.

In Buford GA at the corner of Elm Tree Terrace and Buford Dam road, I was waiting for the light to turn on a decline. It is important to note that the car was driving in all-electric mode on a full charge. Once the light turned green I stepped on the accelerator to go and the car stalled. I believe the transmission slipped. The gears caught at high torque and jolted the car involuntarily forward. I didn't notice it at first but after a couple of sleepless nights with shoulder pain: I got an MRI and was found to have a torn rotator cuff. It is difficult to associate the injury as it is hard to access the force applied to the jolt. The only word I can use to describe the force of the jolt was violent. I believe there is a safety issue when a high torque electric motor is being run through a slipping or failing transmission and I suspect as a result I have suffered a injury as a result.
