I picked up my 2011 Overland in early December, 2010. I've been really happy with my Jeep until this year. I went two full years without any problems at all. I've had two fatal problems this year, both leaving me stranded and requiring a tow. The first was caused by the transmission fluid filter not being installed properly at the factory, and the second was a dead battery caused by a computer glitch involving the lift gate. Both issues appear to be isolated, but still very upsetting.
They were resolved quickly under warranty. Otherwise, I've been very happy with the ride & handling (air suspension), quiet cabin (no squeaks or rattles) and the the HEMI's performance.
