NHTSA complaint #11399039, filed 2021-03, 57,000 miles“I was driving the car down 880 until I suddenly heard a cracklings noise coming from the back of my car. I had just gotten the car serviced a week before so this was very unpleasant and surprising. I ended up turning back and parking my car at home. The next day while driving to the dealer I still heard the noise and there was a weird burning smell. The noise continued even after shutting off the car. I went to the dealer and they diagnosed that the right passenger speaker had melted and they also changed my amp. …”
NHTSA complaint #11331863, filed 2020-06, 67,000 miles“Trunk has opened 6 - 8 times on its own. In just over 5,000 miles of ownership and two documented attempts to repair the problem persists. The trunk opens on its own in nearly any combination of; in motion, stopped, in gear, out of gear, moderate speed (40-50 MPH), low speed (a crawl) cool temps., warm temps., top up, top down. I have even tried, while the car is in motion, to deliberately open the trunk with the key fob and with the door mounted release. It did not open when I tried to replicate an unintentional opening. …”
NHTSA complaint #11366193, filed 2020-10, 35,000 miles“The vehicle was in transit on the highway at cruising speeds when suddenly the right rear speaker began to make noises that sounded like a rattling or crackling. Previously, the car had been making similar crackling noises from the front dashboard, however upon the spread of this noise to the right rear speaker, the car soon filled with the smell of burning rubber and smoke. As the smell progressed, I pulled over in fear of a potential fire and had the vehicle towed after I was told that it could catch on fire if I continued driving it. …”
NHTSA complaint #11219879, filed 2019-06, 42,000 miles“While driving on the highway, I attempted a heavy acceleration to get the car up to traffic speed. Two times in the past 60 days, the car seriously malfunctioned with multiple dashboard indicator lights and the main text pre safe functions limited accompanied by a total loss of speed control. The accelerator became 100% unresponsive and I had to coast to an emergency lane. There was significant danger in both instances as I had to cross multiple lanes of traffic with no power to get to safety. …”
