The car, while driving on a 2 lane road, ceased it operation announcing it had drive train failure. Luckily I was slowing for a light, as the steering and brakes also became unresponsive. The car could be manually turned off (the remaining functions and power off). It then could be turned back on and driven. In other words, the car decided to go off line while in a state of engagement with the road and the driver.

My bmw i3 over the past year when driving at any speed has had a handful of times where power steering becomes extremely twitchy our cuts out completely like it doesn't know what centered is so that I have no power steering and this creates a safety hazard for drivers. The car is unstable and no longer returns to center when taking corners and feels extremely heavy. The only way to fix this is to shut the car off for 3-5 minutes until it resets. Because it happens randomly and there is no error code dealers are unable to duplicate or fix the issue.

The rex (range extender) on my i3 does not turn on, at random, when the battery level of the vehicle gets to a point that is low enough for it to turn on. When this happens, the vehicle experiences a sudden and violent loss of speed with no warning. This has, on more than one occasion, nearly caused an accident while in traffic. The bmw dealership has confirmed this is an issue in my vehicle and has successfully been able to reproduce it on more than one occasion. It has been 'fixed' on more than one occasion as well. The vehicle still experiences this issue intermittently with no warning. The dealership is no longer able to reproduce this issue when taken in for service. The dealership has now taken a stance that the vehicle violently losing power and speed (as if the brakes have been applied heavily) is "operation normally for conditions" and "no actions taken" and advice that this is an acceptable and known and have "advised customer of limitation of driving on the rex with too many customer demands..." the vehicle has experienced the rex not turning on and losing power while in motion and on the highway and surface / light commercial streets at all levels of speed. The direction of travel does not likely have any impact on this. It has happened while going 35mph and also while going 70mph, and other speeds in between. It has been confirmed and happened to myself, my wife, and at least two separate times (during the same trip, on different days) to the dealer while it was in their care for repair.

This car is extremely dangerous. 'the eme malfunction happened the first day that I drove the car after purchasing. Not long after I started driving in the morning the computer said that the rex wasn't working. About 40 minutes later on my trip, the computer said that the car was performing maintenance on the rex. In the evening while driving home, the computer said that the battery was discharging, and then the car lost power on the freeway. I was able to get it to start again after some time. This was particularly scary at the time as I had my 18 month grandson in the back seat. 'the second eme failure was seriously more dangerous. I was traveling on 405 southbound when the power train malfunction warning came on and immediately the car lost power. I was not able to pull off the freeway and the car stopped in the far right lane with no shoulder. Cars were coming up so fast and close. I was afraid for my life so I fled the car and jumped over the guardrail for safety. I called the police and they had to block the lane and put out flares until an emergency tow truck could arrive. 'I am very afraid of this car and since the second event happened I haven't driven the 100-mile journeys for which we bought the car. I babysit my grandson who lives up north, and this is the reason we purchased this car, to save on gas. I do not want to put my grandson in danger so I now use our other car, which does not have good gas mileage. Both times were on the freeway at freeway speeds

Left motor mount bolt broke when traffic light turned green at 4:00 pm in friday rush hour traffic. The bolt failure shifted motor down ~3" and broke power cable(s) and battery cooling lines. The car shifted into "n", once, and rolled off the road into a parking place. Shifted into "p" and contacted bmw road side service. Bmw service asked to shift into "n" but the car remained in "p". They did not have workaround instructions to force it into "n" and reported there were no tire "skates" to slide car on a flat-bed.

Driving southbound on i680 in northern california, car switched to the range extender just before me getting to the altamont pass. Part way up the hill car lost power unexeptedly. Took car back to bmw dealership as it was in the shop the week before for a drive train malfunction. Dealer said this powre loss was normal for the vehicle on the grade as the rex cannot keep high voltage battery charged up enough while going uphill. They said it was to be expected. Nothing received prior to sale information of this possiblity.

I test drove a bmw i3. I got into trouble because they forgot to charge it up completely when I drove it. Almost died. Consumer reports describes it all better than I can: "a new lawsuit alleges that bmw i3 electric cars can suddenly slow down when their battery power is low, potentially putting passengers in dangerous situations. Filed tuesday in u.s. District court in los angeles, the class-action suit alleges that the i3's 'range extender feature ... Doesn't produce enough power to prevent a dramatic decrease in the vehicle's performance. As alleged, if the car is under any kind of significant load (such as going up a hill, or loaded with passengers), the speed of the car will dramatically decrease as the battery charge diminishes,' according to a press release from plaintiff attorney jonathan michaels of newport beach, calif." -- consumer reports magazine reports.
