I have a 2011 Overland built in 12/2010 with 17,000 miles. I've had the right rear turn signal burn out which I replaced myself. Wipers started to streak so I replaced them with Anco wipers. I also just checked the cabin air filter and it was filthy, so I will be going to Napa to get a replacement today.
Ohhh the problems that I've had with my Jeep..... I've had so many issues with this one, I might have to trade it in..... for another
For the air suspension, I don't expect it to be problem free for 15 years. Show me one that has. If/when I do have an issue with it, if it is outside of warrenty, I'll learn how to fix it myself or by that time, I'm sure that there will be after market replacements that will likely be better.
This has been my first Jeep, and we liked it so much we got my wife a wrangler. So far, it looks like I will be a return Jeep customer for a while.
I do miss the service that I got with BMW, but I was also having to get that service far to often when I had my 325xi.
