2018 Jeep Cherokee: engine overheating

Filed Apr 8, 2026 · Transmission · NM

What component or system failed or malfunctioned, and is it available for inspection upon request? The Power Transfer Unit (PTU) has malfunctioned. Specifically, the Drivetrain Control Module (DTCM) is reporting a "TestFailed" status with active fault codes C1440-64 (Transfer Case Clutch Pressure Sensor) and C1477-4B (Transfer Case Clutch - Over Temperature). The vehicle and its diagnostic logs are available for inspection. How was your safety or the safety of others put at risk? The failure creates a risk of sudden loss of motive power while driving or a loss of the PARK function when stationary, both of which can lead to a collision. Furthermore, internal diagnostic data has recorded clutch plate temperatures as high as 437.1°F. This extreme thermal condition represents a significant fire hazard and the potential for mechanical seizure while the vehicle is in motion. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The problem was confirmed by Larry H. Miller Casa Chrysler Jeep after the 01C recall software was installed, which subsequently triggered the "TestFailed" status. Additionally, an independent inspection by Universal Transmission confirmed the specific PTU fault codes and verified that the overheating issue is originating from the PTU. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by a manufacturer-authorized dealership (Larry H. Miller Casa Chrysler Jeep) and an independent service center (Universal Transmission). Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, the vehicle displayed "4WD Overheating," "Temp Unavailable," and "Service 4WD" warning lamps and messages. These symptoms were formally documented in technical scan reports beginning in early March 2026.

2018 Jeep Cherokee Limited, 154k miles currently. Purchased vehicle from third party with under 100k miles. Vehicle maintenance was always done per manufacturer suggestions(from third party and myself), at 152k miles I noticed vehicle overheating when driving 25-55MPH (with AC off). Also noticed a reduction in the powertrain. Vehicle diagnostic done at local mechanic and cleared(no coolant leak, no oil leak engine was in good condition.) Oil change and other regular maintenance work done as well. Then engine eventually blew a gasket, and a hose resulting in me having to replace entire engine and other damaged components due to the engine being poorly built.

Within the last 6 months this vehicle has left me stranded at least 5 times. The first time it overheated because the heating coil is so close to another line that is created a hole that caused the vehicle to overheat. The second time was an ignition coil. The third time was because it was time for an oil change which was not the case because it wasn't even time for an oil change. The other times were (battery) related but yet with the battery being replaced 200 bucks later I am left stranded on the road in the middle of traffic without any indication that it was going to cutoff. I fear taking it on the interstate. Within the last 24 hours I have been left stranded after having the dealership again yesterday tell me I need a new battery which I replaced but yet broke down again this morning. The vehicle will start but it seems like now 2-3 minutes it cuts off while driving and has to be jumped by another vehicle. This has to be an electrical problem...the lights don't dim; everything stays on for a bit once I take the keys out, but yet I am being told my VIN has no recalls. Once again there is no lights or anything that appear on the dash letting me know where is an issue.

I have oil leaking from between the engine and cylinder head which has leaked enough to coat the engine block and is also losing coolant. Dealer diagnosed as a seepage says is normal and says chrysler won't fix it. So according to chrysler your 2.4 engine is supposed to leak and burn oil. This is a fire hazard.

This has been a recurring issue. The on board screen will suddenly show "service shifter" and all the shifter indicator lights go red. This has happened while driving and also at initial starts. When vehicle is shut down and restarted, everything returns to normal. Doing some research that says overheating problems can ensue.
