4/5 Overall
NHTSA 5-Star Safety Rating
For the 2015 Jeep Grand Cherokee, powertrain and seat-related complaints make up the bulk of what owners report, and the volume on both is substantial. On the powertrain side, owners frequently describe the transmission unexpectedly dropping into neutral while driving at highway speeds, often with no warning lights and no fault codes found during dealer inspection. Some also report the engine revving against brake input in what they describe as unintended acceleration, pressing the brake hard and waiting it out is how multiple owners say they managed it. The seat complaints center on headrests, with owners describing the front headrests suddenly and forcefully deploying or lunging forward without any collision. Engine complaints come in well behind those two systems, with a smaller cluster of reports covering performance and stalling concerns. The neutral-drop pattern stands out for occurring repeatedly on the same vehicles, sometimes at different speeds and on separate occasions.

By System
The 2015 Jeep Grand Cherokee has 9 recalls, with several serious issues including a fire risk on 3.0L EcoDiesel models where the exhaust gas recirculation cooler can crack and allow coolant vapor to combust inside the intake manifold.
The diesel engine recalls extend further: a high-pressure fuel pump can shed internal debris into the fuel system and starve the engine of fuel, cutting drive power without warning, and a crankshaft sensor component can delaminate and cause the engine to stall while driving. There is also a software vulnerability in the infotainment system that can allow unauthorized remote access and control of certain vehicle functions. A separate software defect can cause the cruise control to maintain or increase speed even when the driver tries to turn it off. On the suspension side, certain rear lower control arms can fracture, causing a drop in ride height and loss of rear stability and braking. The transmission gear selector can give a false indication of being in Park, meaning the vehicle may roll when the driver gets out. A brake caliper on some vehicles can crack and extend stopping distances. The transmission control module can also misread the selected gear, leaving the vehicle at risk of rolling when the driver believes it is parked.

What can fail
The crankshaft position sensor tone wheel may separate into layers, causing the engine to lose synchronization between fuel injector timing and camshaft timing, which can result in engine stall.
What the fix does
Dealers will update the engine control software to read the camshaft position signal if the crankshaft position signal is lost, maintaining engine operation.

What can fail
A wiring short circuit can prevent cruise control from disengaging. When engaged, you may not be able to turn it off by braking or using manual controls, causing the vehicle to maintain speed or accelerate unexpectedly.
What the fix does
Dealers will update the engine or powertrain control module software at no cost to fix the cruise control disengagement issue.
