Three problems related to service engine light on have been reported for the 2014 Jeep Cherokee. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2014 Jeep Cherokee based on all problems reported for the 2014 Cherokee.
Service engine light comes on while in motion on the highway when trips are over 45 minutes. While service engine is lit up, the car will not accelerate and I have to pull over to the shoulder. After turning engine off and back on, car will then accelerate. This has been taken to the dealership and code was p1da9. Dealer claims that there is nothing they can do to fix this code at the moment. Code was cleared and after another trip, the same code came up.
On 2 seperate occasions in the past month, vehicle is driving straight on the highway just fine when the vehicle unexpectedly loses power (does not stall, simply will not maintain speed, until vehicle finally coasts to a stop as the momentum fades). Transmission light & other lights illuminate, finally the service engine light remains lit. After a prolonged resting of the vehicle (typically 15 minutes or more) the vehicle then becomes able to move again, but must accelerate very slowly at first. Eventually vehicle can resume normal speed. Very dangerous as vehicle loses ability to move during crowded rush hour traffic!.
The car is only 5 months old. Has a zf 9 speed automatic transmission and 3. 2l 46 24v -vvt engine. I was driving on a tollway in moderate traffic at a speed of approximately 60-65 mph. Without slowing down or changing speed, the display on the dash listed "service transmission". All power to the engine was lost and car began to slow down. Would not respond to acceleration. Check engine light, stability control light, p! were all displayed. Had to find a way to the shoulder and stop car. Turned off car and restarted it. "check transmission " was displayed. Put it in drive and it felt like it was starting in 2nd or 3rd gear. Would not shift gears. Could get up to 35 mph with the tach at 2000 rpm. Would not shift at all. Got home and let car sit for a few hours. Started car after sitting for a few hours and the "service transmission" was gone. All other warning lights were gone except for service engine light. Drove to dealer next day and car appeared to shift ok. Dealer loaded pcm flash update. Reprogrammed tcm per TSB 21-018-14. Reprogrammed rf hub per 08-077-14. Car appears to be driving ok. Dealer said they couldn't find any problems with the transmission. They treated this very lightly . I feel this is a significant safety issue. Lossed all acceleration and controll at high speed. No notification of updates were sent previously.
