Jeep Wrangler Used Buying Guide: Known Issues

• Common Jeep Wrangler issues range from electrical failure to faulty welding.
• For the most reliable ride, shop the used market for late-model Wranglers.
• Old-school drivers and Wrangler enthusiasts can avoid a bevy of electrical issues with older Wrangler models, which also have a solid reputation for reliability.
• At Alan Jay, we only offer the best versions of Jeep’s iconic off-road SUV!

Although some of these problems are pretty widespread across the board, keep in mind that the most common issues don’t necessarily affect every model year! To help you sort through the used market, we’ve listed the Wranglers most likely to experience each issue.

Outside of the proverbial “death wobble” (more on this below), the main problem plaguing the latest generation of Wranglers has been welding — namely, improper welding in the intermediate steering shaft and track bar brackets. Luckily, though, the NHTSA issued safety recalls for both issues. Check the NHTSA website to verify that your used Jeep Wrangler has received the necessary repairs.

Wranglers that may be affected:

• Any 2018-2019 Wrangler models

As the Wrangler’s central electrical control unit, a faulty TIPM can wreak havoc just about anywhere electricity is involved. Without it, the fuel pump can’t transport gas to the engine, power windows become inoperable, the electronic throttle control goes kaput… you get the idea. This issue is so widespread among Chrysler models that there have been times when replacement TIPMs were on national backorder.

Wranglers that may be affected:

• Any 2007-2015 Wrangler models

Unfortunately, we’re not exaggerating. Many Wrangler owners have gone to fill up their tank, only to find gasoline suddenly gushing everywhere. Apparently an inlet check valve in the fuel-tank filler tube gets stuck. If that happens, the fuel system doesn’t respond to the shut-off mechanism and gas keeps pumping, even after the tank overflows. For 2007-2008 Wranglers, a lifetime powertrain limited warranty makes it easy to deal with this problem. Unfortunately, though, this issue may extend beyond those model years.

Wranglers that may be affected:

• Second-generation Wrangler (1996-2006)
• Third-generation Wrangler (2007-2017)

The Wrangler’s available electronic sway bar disconnects to enhance off-road performance. Unfortunately, some model years are equipped with a version of this equipment that’s too sensitive to wet conditions. Many drivers have found that when it’s time to return to the pavement, the disconnecting sway bar won’t reconnect due to an electrical failure. Faulty seals and electrical insulation seem to be the main culprits.

Wranglers that may be affected:

• 2007-2017 Wrangler Rubicon (JK)
• 2007-2017 Wrangler Unlimited Rubicon (JKU)
• 2018-2020 Wrangler Unlimited Rubicon (JLU)

In spite of its off-roading genius, one weak link in the Wrangler’s suspension setup can lead to shaky wheels. This issue is so common that Wrangler drivers have a nickname for it: the death wobble. There are many possible causes, but the wobble is generally rooted in worn-out steering or suspension parts. Some potential fixes include aligning the wheels, balancing the tires, or replacing the ball joints. Even low tire pressure can cause the death wobble. In general, you can avoid a teetering ride by opting for high-quality suspension parts and carefully maintaining them.

Wranglers that may be affected:

• 1997-current model Wrangler

Interestingly, the Jeeps with the best reputations are both the newest and oldest model years. Between the 2021 and 2022 model years, the Kelley Blue Book repair forecast greatly improved for the Wrangler. Whereas 2021 Wrangler drivers were paying around $100 a year for repair costs pretty much from the jump, the average 2022 Wrangler didn’t need any repairs until after it hit 36,000 miles.

Then there are the models from the early 2000s and 1990s — especially the 2003 and 1997 Wrangler. While these older SUVs may require routine maintenance to replace worn-out parts, they continue to rack up the least customer complaints, even after decades on the road. With durable parts and less reliance on electrical components, these off-roading SUVs are perfect for old-school drivers and DIY mechanic types.
