This happened to mine early on bc I put the rear seats up and down a lot. They fixed it under warranty. Now I feed the belts cautiously during folding/unfolding the seats to avoid any repeats. Stupid jeep engineers. My Grand Wagoneer, Cherokee Sport, Grand Cherokee Limited, LJ all had flawless seatbelt interaction when folding the seats. Then again the stupid F$!%# engineers and bean counters also removed the rear view mirror lights that all the aforementioned Jeeps had too. The JK is refined but also has done seriously annoying but minor flaws!
