Overheating on other Wrangler years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2015, 2016, 2017, 2018, 2019, 2020, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
Most owners in this group notice the coolant before they notice the heat: a reservoir that keeps dropping, a sweet smell, or a bright puddle under the front of the car.

What got replaced

Is this a known problem?
The manufacturer has sent NHTSA 4 service bulletins or notices for the 2014 Jeep Wrangler that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote
“My Jeep only has 60,000 and I already have to replace the oil cooler on it. This causes the radiator fluid to leak and overheated my car. This could cause major damage to my engine and its components. This would also cause the oil to leak into my coolant reservoir. Itâs a major defect by Jeep and needs modifications.”

Should you keep driving it?
This page can't tell you that. 0 of 34 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
