Driver's side tire continues to leak air - note low tire pressure even with new tire replacement. Airmatic Suspension failure. Rear airbag suspension airbag. Compression also failed. Several complaints to dealer advising the car was bouncing up and down while in drive. Took vehicle to the shop with suspension complaints at the end of April 2021. We were told they did not find an issue with suspension but saw an issue with the sway bar. This cost $549. The week we brought the car home it was still bouncing up and down and we contacted the dealer again and was advised they did not find anything wrong. Within 2 weeks of having the vehicle, I was driving and the vehicle was violently bouncing up and down even traveling at a low level. We took the vehicle back and have not been advised now that they see the malfunction light for the suspension on they realize that's the issue. The suggested cost to repair only the rear is $4k. If the front and rear need repairs it over $7k. The issue is it appears this is a known issue for the Airmatic system and with a vehicle in this price range and under 90k miles - appears to be a issue with manufacturing. I was also advised this repair is no longer covered on their extended warranty.
