NHTSA Complaint #11466777 — 2021 JEEP GLADIATOR

3.0 EcoDiesel in the Jeep Gladiator has cooling issues. Thousands of users affected and discussing on forums and on Facebook groups but the manufacturer is unwilling to fix. Core of the issue is that the engine was altered in the Gladiator and Wrangler over previous installations in the Ram and Grand Cherokee by removing oil coolers and a larger oil pan, which has resulted in high oil temps. At 265 degrees (which is accomplished easily during the summer with a trailer UNDER the tow rating), the engine starts derating and limp mode. The aftermarket community has tested everything ... removing hoods, fenders different cooling solutions, etc and nothing is working at the moment other than aftermarket solutions to cool the oil (which are negligible at best at the moment due to the space constraints imposed by the engine being quite large in the engine bay not not substantial room for a larger oil pan and external cooler). Chrysler should have put more work in to the design, or not sold the EcoDiesel in the vehicle.
