Example complaints
Transmission and drivetrain: “On september 20th, 2018, the car suffered a sudden and abrupt catastrophic shut down while I was driving my son to school. We were on city streets driving straight at normal speed and it stalled right in an intersection but I was lucky to be able to still have some momentum to get into the left turn lane. There was a flashing red text warning on the display for a few seconds- something about turn off immediately and do not restart. Then the car shut down. I was terrified that we would get into an accident all throughout the time we had to wait for the tow truck. …”
NHTSA complaint #11140783, filed 2018-10, 45,559 milesElectrical system: “While operating the vehicle on the road the car lost the ability to accelerate beyond 10 mile per hour; fortunately, we were just blocks away from our home. My wife call the service center and they picked it up and provided her with a loaner. While driving at 35 MPH, the vehicle decelerated without warning. The vehicle was taken to the dealer for diagnostic testing. The technician performed a software update on the vehicle. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 8,184.”
NHTSA complaint #10778583, filed 2015-09, 8,184 milesEngine: “I was cruising down a pretty busy main street. As I was trying to manuever in traffic, I sensed that as I was pressing on the gas, the car was unresponsive. I looked at the dash and noticed the car had moved itself into neutral. I tried to turn the key, but nothing happened. The car was unresponsive, but still on (from the look of the dashboard). I quickly tried to coast to the side of the road, in between speeding traffic, which was very dangerous, as I was near the highway onramp area. Once I safely pulled aside, I tried to again turn the car on using the key. Again the car was unresponsive. …”
NHTSA complaint #10743359, filed 2015-07, 4,910 milesBrakes: “This is an electric vehicle. When slowing down the paddle shifters can be used to put the car in 'd-' mode, for more aggressive engine braking. This increases the rate of decl without using the mechanical brakes. This has worked well for four years and 65,000 miles. Today there was a 'one time' malfunction. I did the usual 'd-' 'down shift' to slowdown from 30 MPH, in traffic, for red light. The car did not aggressively slow down and I applied the brakes. I noticed the car need excessive break pedal pressure to make what should be a normal stop. …”
