Are Jeep Wranglers Reliable After 100K Miles? What Users Are Saying

One thing Jeep Wranglers are good at is dividing opinion. On the one hand, many Wrangler owners see this quintessentially American four-wheel-drive as unstoppable, the epitome of off-road toughness. On the other, this iconic Jeep with its seven-slot grille draws a barrage of criticism from its detractors, who take every opportunity to ridicule the Jeep faithful — a fan base as rusted-on as the bolts on a TJ undercarriage.

Born in 1941 out of the United States’ desire to bring an end to World War II, Jeeps are as good as anything on the market for off-roading, rock crawling, and trail-climbing, and continue to hold their own against lower-priced imports and fierce SUV competition. The brand has survived a string of ownership changes, from the early American Bantam, Willys-Overland, and Kaiser days to its current stewardship under Stellantis — via AMC, Renault, and some convoluted Chrysler-Daimler-Fiat iterations. Through it all, Jeep retained its own ruggedly individual identity.

But while a Wrangler is one of the best new off-road vehicles out there, is it reliable in the long haul? To find out, we headed to the Jeep forums. Jeep wheelers just love talking all things Jeep. It’s a Jeep thing. Like “ducking”, where a toy rubber duck is placed on an unsuspecting owner’s rig — a custom that polarizes opinions. When it comes to the high-mileage reliability of the Wrangler, however, Jeep owners are less divided. Are owners happy with their Wranglers, 100,000 miles on? Judging by user comments on the forums, yes they are.

Rusted frames, oil leaks, and damage from wheeling

The current fourth generation JL Wrangler rolled off the production line in 2018, so the majority are yet to reach their 100k milestone. Most forum discussions on high-mileage Wranglers revolve around the JK (2007-2018), with some pitching in stories on their 100k TJ (1997-2006), but scant mention of the first Wrangler, the YJ (1987-1995) — perhaps because even hardcore Jeep fans find it embarrassingly ugly.

On the Wrangler subreddit, users with 100k on their vehicle say they needed little more than maintenance and the odd replacement part. Water pumps, radiators, oil coolers, and alternators are commonly cited, along with slave cylinders. “My 2018 has 111k,” says Reddit user Moleculoso. “Other than a water pump and some warranty stuff, it’s been great.” Rusted frames and oil leaks are mentioned, with Lugknots reporting a “blown rear brake cylinder; minor valve cover oil leak; small transmission rear seal leak” on a 2004 TJ with 103k miles, while BlackthorneBuilds advises buyers “Check the rear corners for rust, just like you check the frame rails for rust” on 100k Wranglers.

Others warn if the Jeep has been wheeled heavily, steering and suspension components — ball joints, tie rod ends, rods, track bars, and links — may need replacing. “130-140k means nothing to me, as long as the frame is clean,” writes OldManJeepin. “Bone stock … I will not touch anything lifted or modded.” Southern-Mushroom536 reports steering system issues from oversized tires as “self-inflicted since I put 37s on it.”

What to watch out for

It’s not all beer and skittles, however. One owner had problems with a 2007 JK at just under 100k miles. “Had to rebuild most of the front end,” Tall-Poem-6808 writes. “Then the radiator started leaking, and the clutch is getting replaced this week … and it drinks 5 quarts of oil in 4000 miles.” Valve lifters are also cited as a common issue, with owners warned to listen for tell-tale ticking, particularly in the Pentastar 3.6 liter V6 engine.

“My 2015 had the Pentastar tick,” writes No_Space_B4_Comma. “Left head replaced at 90k, right head replaced at 130k”. This came on top of master cylinder failure, the radio dying twice, and a leaking radiator. Despite these horror stories, most users say a high-mileage Wrangler is a reliable ride, provided it has had regular fluid changes and preventative maintenance checks, including replacing parts at or near the end of their service life.

Buyers looking for advice on buying high-mileage Wranglers were given reassurances by forum members, with the caveat that the vehicle should be unmodified with a solid service history. “Just understand you’re buying something which is about to start having some problems,” writes BlackthorneBuilds, “but if it’s been maintained correctly and not abused, you’re fine. They hold value pretty well. If you’re mechanically inclined, it shouldn’t be a big deal.” Plaguezzz agrees, pointing to “gaskets, water pump, spark plugs, radiator, hoses, various emissions sensors” as likely being ready for replacement at the 100,000-mile mark.
