2015 Jeep Grand Cherokee power train problems

“The contact rented a 2015 Jeep Grand Cherokee. The contact stated that while driving at 55 MPH or higher, the steering wheel shook violently. The vehicle was taken to a certified mechanic who diagnosed that the front left tie rod, brake assembly, gear shifter, tires, and several electrical components required replacement or repair. As instructed, the vehicle was returned to the rental business. The failure mileage was approximately 200,000. The VIN was not available.”

“Recall 20V-475 / 23V-411 software patch was performed, but the underlying magnetic tone wheel defect has now physically failed, causing an active crankshaft position sensor error and stall hazard. While traveling 60mph the car stalled and went into limp mode with no prior warning. The vehicle has been diagnosed at a repair shop as a fault with the crankshaft position sensor performance which was apart of a pervious recall listed above. The vehicle has not been inspected by any others at this time as its not safe to drive and do not want out of pocket cost to do so.”

“I own a 2015 Jeep Grand Cherokee Summit 4x4 with the 3.0L EcoDiesel, with approximately 113,170 miles. The vehicle has experienced multiple intermittent episodes of “Service Electronic Throttle Control.” During the most recent episode, the vehicle briefly jerked/lurched forward and then experienced a significant loss of engine power/boost. I scanned the vehicle and found DTC P0336 (Crankshaft Position Sensor A Performance, intermittent). Clearing the code temporarily restored normal operation, but the fault later returned. During the most recent recurrence, the engine also cranked noticeably longer than normal before starting. FCA previously issued safety recall W79 concerning loss of crankshaft-position signal on these vehicles. The recall involved a software update intended to maintain engine operation using the camshaft signal if the crankshaft signal is lost. FCA also lists warranty extension X95 concerning the 3.0L diesel crankshaft tone wheel. FCA technical documentation identifies P0336 as a possible symptom associated with crankshaft tone-wheel magnetic material failure. The vehicle has not yet been inspected by a dealer or independent shop to confirm…”

“System Failed: Total engine failure caused by a defective Recall W79 EGR Cooler, which is available for physical inspection at my residence.Safety Risk: The vehicle suffered a sudden, complete loss of motive power at speed. This caused an immediate traffic hazard, risking a catastrophic rear-end collision due to lost propulsion, power steering, and braking.Dealer Verification: The vehicle is currently undrivable. Jeep Corporate is actively giving me the runaround and refusing to tow or diagnose the vehicle under the EcoDiesel Settlement Extended Warranty.Inspections: No inspections have been conducted yet by police, insurance, or the manufacturer; the vehicle is fully preserved.Symptoms/Warning: No long-term warning lights appeared. The vehicle suddenly lost AC cooling and instantly stalled out without advanced mechanical warning.”

“No check engine lights prior to this, car started to make a noise pulled over to check it out as I was merging over low oil pressure showed and coolant level over temperature, gear then dropped to neutral, managed to pull over without any accidents car then shut off, oil leaked, it makes a horrible engine noise when starting, had to tow it back. only had the car a year maintenance was up to date.”

“ACC automatically canceled without braking causing car to either slow down immediately or speed up unsafely, slippery road light turns on, on dash while driving straight, lunging of the car that feels like tires are spinning and or hesitation.”
