Please read this. You don't deserve to endure what I've endured over 1.5 years. I've had the entire fuel assembly replaced; the entire air compressor suspension replaced; the air bag assembly replaced; the radio (twice) and the inside of the rear tires are bald while the outside are in fine shape, due to a major suspension design flaw. It now lives in the garage until my lease is up (I rent cars to travel for my job.)
If I can safely get to a mountain, it holds the road very well.
Recall the entire vehicle and replace it and acknowledge that you create a bottom-of-the-barrel product with an expensive price tag.
