What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Fuel leaking onto exhaust system had to tow to dealer due to freighting experience of possible fire and injury to myself and others. Dealer stated cost would be a min. 1000 dollars would have to remove fuel tank to access problem and stated a two day wait on parts to repair ..car has 16000 mi on it.
Passenger side headlamp failed after condensation build up in the headlight assembly. I have the hid headlamps and changed the bulbs checked all the fuses and relays but it still will not work consistently.
Driving home on the interstate at the posted 70 mph speed my electronic stability light goes off and the cars engaged suddenly begins to rapidly power down. A few moments later I was unable to maintain 40 mph as the transition revived to 2x normal levels.
Led taillights are distracting, especially those with low refresh rates. The human retina takes 1ms to take a snapshot of the world, so lights with a refresh rate below 1000hz should be banned from the roads. Cadillacs in particular are bad, with refresh rates apparently around 60hz or so.
