What 2018 BMW i3 owners say
Steering
Hello , I am owning a BMW i3REX (2018). Recently like many other users experienced multiple times the loss of power steering after starting the vehicle. While previous events like this were short lived and resolved with stopping, turning off and on the vehicle, this time it was on entering a highway, where the car suddenly lost its power steering and could not be driven properly. I had to exit , switched the car off and restart after a couple of minutes, which resolved this problem completely. I am reporting this to you, as I see this as a major safety risk for the BMW i3, which as it seems also other driver experiences and so far no solution has been found by BMW (please see https://www.mybmwi3.com/forum/viewtopic.php?t=5065) ?
On two occasions the power steering failed while i was driving, once several months ago and again last Wednesday. Fortunately i was driving on surface streets close to home. i parked the car for twenty minutes and upon starting it the problem seemed to be gone. After the first occurance i went to the dealer and they said they knew nothing about the problem. I also called BMW USA.... again they knew nothing. The second time, last week, i took the car to the dealer again and they located a software update. Without actually acknowledging the problem, BMW had a software update and after initially asking me to pay for it, they agreed to pay.
Speed control & acceleration
The contact owns a 2018 BMW i3. The contact stated that while driving in the rain at approximately 45 - 50 MPH, the vehicle had unintended acceleration and the contact lost control of the vehicle. The vehicle came to a full stop after getting stuck in the mud on the side of the road. The failure nearly caused a collision. The dealer was made aware of the failure; however, the vehicle was not diagnosed nor repaired. The dealer referred the contact to the manufacturer. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 42,600.
On May 2, 2022, the car began to power down involuntarily every time I applied the brakes. This happened 2-3 times, and I was able to restart. The final time was in the middle of an intersection, the car would not restart, could not be placed in neutral to be moved out of the intersection, and I had to have a police tow. The tow service took it to Sport Motoring, where they performed a diagnosis on May 3, 2022. The diagnosis shows 8 faults in the EME module, among other things. I located a recall (Recall #19V310000) for the 2018 i3 which details the exact issue of the car powering down on its own due to a faulty EME module. Sport Motoring called BMW Customer Service on May 3, 2022, and asked if the car might need to have this recall applied. They agreed that the symptoms did seem similar and said they would need to have a diagnosis from a dealer. …
Fuel & propulsion system
This isn't a safety issue, rather it's a known problem with the factory AC compressor inside of BMW i3s and i8s that seem to constantly fail. I had a replacement under the car's factory warranty and the part already failed again right outside the part's warranty period. The replacement itself was quoted as a little over $9,000 but the dealership has since gone down to just under $4,000 to replace something that's just 2 months outside of warranty (but is probably something that would have failed an inspection had I just "taken it in" earlier). NUMEROUS people in online forums have confirmed this to be a known issue, but the company is holding their ground. Car companies should be held to a higher standard, and I'd like to ask the NHTSA to intervene and assist in this matter.
