Hello all. I'm new to Jeep. I bought my first three weeks ago. Jeep Cherokee Limited V6, 4wd. So far, I'm very nervous for its future. I kept getting a message that read, 4wd unavailable, service required. I took it in twice, only to be sent away after the dealership rebooted the software. This time around, I was told I need a new PTU, old term transfer case. Thoughts? Experiences? This is hard to deal with considering my last car was a RAV4 with 160k miles and I never replaced a thing besides brakes twice and tires once. Jeep IS better than this, right?
