I think that’s more on older ones.
I have an 01 with 150k, both have been flawless. My mom drives an 01 XJ with 185k, and both items are original.
I did do a CPS on my brother’s 96 Grand Cherokee at 115k. They must have improved the system because the 01s have DIS, and seem to last far longer.
As far as starters on 4.slow Jeeps, so far so good.
In general, 4.0 Jeeps are extremely reliable. Much like DSMs that people buy for $2k and blow up in weeks because they spend money on mods only and not maintenance, the 100k+ Jeeps that have been packed with mud and washed out a dozen times tend to break down a lot. While the Chrysler built Jeeps have their fair share of problems, a lot of them electrical, they seem to start and drive very reliably. Now if you’ve ever had death wobble, you may have a different opinion, but they still start and drive, haha.
