6 months ago, I was driving on the interstate and the ESC system light came on, the vehicle lost power/ability to accelerate, and would only allow acceleration after pulling over and restarting the car. This happened several more times on the interstate, and when the ESC system kicked in it would suddenly lurch the car down about 15 mph and leave no ability to accelerate, causing near collisions at high rates of speed. After eventually taking it to the dealership, it turned out to be failed lifters on the driver's side cam shaft, a known design issue that has apparently plagued the Pentastar engines. This all happened in spite of meticulous maintenance and no warning signs from the engine whatsoever. How is such a significant, known design defect that causes such dangerous driving conditions never been flagged for a recall?

The engine and powertrain are affected by a defect described in Safety Recall 66A / the federal safety agency 23V‑411 (loss of crankshaft position). Despite the recall software update being performed, my 2014 Jeep Grand Cherokee continues to display Diagnostic Trouble Code P0336 (Crankshaft Position Sensor Performance). This issue causes intermittent stalling, hard starts, and loss of engine power, which creates a serious risk of crash if the vehicle stalls while driving. The safety defect described in the recall — tone wheel magnetic material delamination leading to crankshaft signal loss — is still present. Two diagnostic reports (one from an FCA-authorized dealership and one from an independent mechanic) confirm the presence of DTC P0336. The Service Manager at the dealership agreed this is likely recall-related but said FCA corporate must authorize hardware repair. FCA (Case #93427994) has refused to approve full repair, leaving the safety defect unresolved. The defect has been confirmed by the dealership and independent service center and persists despite the software reprogramming remedy. Warning lights (check engine) are active and the issue is repeatable.

the federal safety agency recall # 23V‑411 (FCA#66A) was performed, but did not fix the issue with lost power. Even though the recall "fix" didn't work, FCA said that the proper fix wasn't covered, because the vehicle isn't under warranty. According to the dealership, the tone wheel needs replaced, and they said FCA should cover the cost.

While traveling down the highway with my gastank 3/4 full my car suddenly lost all power. Thankfully the large truck behind me and the car beside me were alert and they let me glide into the breakdown lane, where I was able to put the car into park and restart it. After doing a search I have noticed 2014 jeeps have been recalled for this issue, although when I entered my VIN a recall didn't come up.

I have a 2014 keep grand Cherokee. The car has made shifting noises and changed gears.The sensor goes on and then comes off.The car had suddenly lost power and then it makes a clinking sound and goes back to gear.. I was on the highway when this happened and almost got into a crash.This vehicle is not used often and well maintained.I took it to be checked from diagnostic and it read codes about a module and defective cranks.The shop informed me that many people were having the same issues and that there was a recall due to this.That the crank shift position was defective and causing transmission issues as well.He also stated that recalls for software issue that needed to be updated which many 2014 jeeps had the same issues. I called Chrysler to find out about the recalls and they stated that there were2014recalls for this but not my vin number.I informed them that I believe my car was also in need of this recall and defective parts because many of the things that were happening were the same as the recall and the model. They said they couldn’t help me and to take it to keep to be checked. I made an appointment and told Chrysler that the problems what the shop said about recalls and it software update.They stated that this has been happening but since my vin was not recalled yet that I would have to cover whatever cost to be fixed.I paid for it to be evaluated by them and they stated it is going to cost 8000 to repair because of the shift and it has a transmission replacement.My vehicle only has 61000 miles. I feel Chrysler is deceiving customers and also selling defective cars that can be fatal.They are not taking responsibility for defectives and leaving the consumer blindsided by costs.I paid a lot of money for this vehicle when purchased 35000 and I have only used 40000 miles in six years. My family and I could of lost our lives due to defective parts in vehicle.
