What You Need to Know Before Buying Your First Jeep
Jeeps rank 18th out of 32 manufacturers for reliability with $583 average annual repair costs. They’re built for off-road capability, not daily-driver dependability. Here’s what that means for your wallet and peace of mind.
What Makes a Vehicle Reliable
Reliability comes down to three factors: how often it breaks, how much repairs cost, and how inconvenient breakdowns are. Jeeps struggle with the first two.
Jeep’s Reliability Numbers
According to J.D. Power’s 2019 Vehicle Dependability Study, Jeep ranked 18th out of 32 manufacturers – below industry average.
Average annual repairs: $583 (above average) Bottom line: Expect higher ownership costs than mainstream brands
