A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
My concern is a potential unintended acceleration forward as. I was. parking vechicle. Sudden burst of speed, went thru shrubbery and off a 2 foot wall. Felt as if we were taking off a runway in a plane. Car went nose up over the wall and then dropped into a neighbor yard digging a divot, ripping rear left fender and bumper with some undercarriage problems. My spouse and I were seatbelted and not injured.
Instrument cluster lighting is too bright even on lowest setting. Combined with poor side visibility from headlamps it is easy to hit object or pedestrians when turning on unlit areas. Have run over a curb three times and damaged two wheels because they can't be seen from the overly bright instrument lighting at night.
