“Our car would not make it up the hill during a rainstorm on the highway in camarillo, ca. It went from 65 down to 45. It happened to us twice on this trip. We were using the range extender. We have videos the vehicle losing power.”
NHTSA complaint #10946914, filed 2017-01, 14,000 miles“2015 Bmw I3 with range extender (rex) just hit 1000 miles. Had for 6 weeks. I was traveling down a freeway at 75 MPH using my electric car. As the battery was almost out of juice, I knew the fuel range extender would kick in. However, when the extender kicked in, my MPH immediately started to drop. Within the 15 seconds, I was down to 35 MPH from the 75 I was traveling. I had the accelerator floored, but could not get any power to keep up with the flow of traffic. With my hazard lights turned on. My car and I safely navigated to the side of the road. …”
NHTSA complaint #10817494, filed 2016-01, 985 miles“The acc (active cruise control) surprisingly stops working when facing a bright sun. This happens often, but it took me a while to understand what was happening. It is very dangerous at high speeds if someone is behind me. When the sun hits the camera, the acc shuts down (with a warning on the screen) and the regen braking system kicks in causing the car to slow down much more than coasting. I have been told that the brake lights go on, but if a car is following and traffic conditions do not suggest that our car should be braking, the car could rear end us. …”
NHTSA complaint #10839234, filed 2016-03, 400 miles“The cruise control randomly turns itself off and the car immediately goes into regenerative braking. The service technician was unable to duplicate the problem and no repairs were performed by the dealer. It has happened under many different driving conditions, and different times of the day and night on freeways and back roads.”
NHTSA complaint #11175174, filed 2019-02, 21,000 miles“The adaptive cruise control (acc) in the I3 is single camera based, and will deactivate during a number of conditions (such as driving into direct sunlight which blinds the camera.) this is a design limitation, but not the problem. The problem is when acc deactivates, the car immediately goes into full regen braking without warning. At highway speeds this is a sudden and significant deceleration that poses a safety hazard (being rear ended).”
