2012 Jeep Grand Cherokee: engine knocking or ticking

Filed Sep 29, 2020 · Transmission · 80,100 miles · GA

While travelling on the interstate at approx 70 MPH, the vehicle lost torque and lost ability to accelerate and had a loud knocking noise while hitting gas pedal. Vehicle is only 80,100 of 100,000/5 year powertrain warranty. Dealer would not warranty this powertrain issue even though the VIN has multiple earlier powertrain warranty items completed. Dealer diagnosed as front transfer case internally failed, and front drive shaft has failed. My independent mechanic indicated this failure is common and may also require a front differential replacement. The dealer initially diagnosed as front differential failure but determined it to be the transfer case. Parts are not readily available due to this being a common failure (4+ weeks for parts). A font drive shaft and transfer case failures are very dangerous and can cause the vehicle to crash.

Vehicle shuts off after starting, ticking from engine at random speeds, runs rough at random speeds during different times. I took it to my dealer because of this and they said that it sounds like the fuel pump relay is failing and can cause me to crash/stop in the middle of the road suddenly and that theres been a recall for this for almost a year but they cant help me or fix my car because theres no parts. I am now afraid to drive at all

A ticking noise coming from the engine area. When accelerating the ticking gets louder. Had noise checked by mechanic and it was the lifter and rocker arm. Had some replaced, this would be the third time. I have a 3.7 engine v6 grand cherokee and found that dodge has a recall for the charger, which is the same company.

On the first of march, my wife and daughter were about to start their day in the usual way. She opened the garage door and used her key fob to remote start our 2012 jeep gc limited ( around 42k miles) ( factory installed remote starter) she walked away for less than 4 minutes and returned to see smoke coming from front passenger side of jeep. She called for me, and pushed the aux button to be sure the vehicle was off. I came running and despite my attempts to open the hood and beat back what quickly escalated into open flames I retreated to ensure my family's safety and to be sure the emergency responders were called. Thankfully I was able to remove some potential fuel for the fire by removing our second car from the garage (also a chrysler) and securing the door between the house and garage. Luck intervened when the flames destroyed the garage door assembly causing the garage door to fall and help remove some oxygen from the fire. Eventually first responders arrived and were able to knock down the fire with foam . Later the firemen pushed the jeep into the driveway to ensure it was doused. Though the remote start may not be directly responsible for whatever arc sparked the fire, it's my belief that its use contributed directly to the conditions that conflagrated the situation. If the wiring harness is otherwise suspect I would not be surprised considering recent revelations on related models. The vehicle was just removed from the site today 3/9/2016 to copart facility, by insurance company for further investigation into the source of the fire.
