2015 JEEP GRAND CHEROKEE with 95500.0 miles
This 2015 Jeep Grand Cherokee ecodiesel has an open recall for the egr system (recall w79). On december 29, 2020, the malfunction indicator light came on. I called the dealer (turnersville Jeep) for an appointment on monday, january 4, 2021. The first available appointment was on tuesday, january 12 2021. This dealer kept the vehicle until friday, january 15. This dealer declined to repair the egr system under the w79 recall, but did replace all fuel injectors and the fuel tubes after finding the fuel injectors restricted. This dealer then cleared the dtc P026C-00 and performed a stationary regeneration. I picked the vehicle up at 5:15 pm on friday, january 15, 2021 and proceeded to road test the vehicle. After about 75 miles of driving, i suffered a exteme and sudden loss of power at approximately 7:30 pm; the dash indicators included the malfunction indicator lamp, an error regarding the throttle body, and an error that the oil pressure was low. As i coasted to a stop, smoke began to rapidly pour from the hood cover and began to enter the cabin through the hvac vents. I vacated the vehicle immediately and under some duress. The smoke continued to billow from the engine area of the vehicle and i could see it continue to enter the cabin. At approximately 9:00 pm on january 15, the vehicle was delivered by flatbed to pellegrino Jeep. I spoke with the pellegrino Jeep service department on saturday, january 16, 2021, but they were unable to provide a commitment to examine the vehicle. I opened case #78239258 with fca (Jeep) us llc customer service. As of january 20 at 11:30 am, i do not have feedback on this case. The dealer has also provided no commitment to examine the vehicle. I believe this vehicle suffered a failure due to the inability of fca and it's dealers to remediate recall w79.
