i have never had a problem with reliability. my grand cherokee has 209k on the clock, my hubby's yj has 109k, my cj7 has 175k, and my hubby traded in his 2001 TJ with 125k on the clock. the wranglers have their quirks, but so do most vehicles. the only issues i have ever had were as a result of me off roading. my daily driver is a 2005 X with 80k, every time i turn the key it starts and drives, that is all i ask of a dd.
