2015 Jeep Grand Cherokee Problems

0L Diesel engines. The crankshaft position sensor tone wheel may delaminate, causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall. An engine stall can increase the risk of a crash.

Fix: Dealers will update the powertrain control module software to maintain vehicle propulsion, free of charge. This recall is an expansion of recall 20V-475.

0L diesel engines. A high pressure fuel pump (HPFP) failure may introduce internal debris into the fuel system, potentially resulting in fuel starvation. Fuel starvation may result in an unexpected loss of drive power, increasing the risk of a crash.

Fix: Dealers will replace the HPFP, and inspect and replace, if necessary, additional fuel system components, free of charge.

0L EcoDiesel engines. The Exhaust Gas Recirculation (EGR) cooler may crack and allow pre-heated vaporized coolant to enter the EGR system. This mixture may combust inside the intake manifold. Combustion in the intake manifold can increase the risk of a fire.

Fix: FCA US LLC will notify owners, and dealers will replace the EGR cooler, free of charge. Dealers will also inspect and, as necessary, replace the intake manifold.

0L diesel engines. The crankshaft position sensor tone wheel may delaminate causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall. An engine stall can increase the risk of a crash.

Fix: FCA US will notify owners, and dealers will update the powertrain control module software to maintain vehicle propulsion by reading the camshaft position signal in the event that the crankshaft position signal is lost, free of charge.

These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating. If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.

Fix: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. Note: Owners are advised to stop using cruise control until the software update has been performed.

The supercharger mounting bracket may contact and damage the ABS line, possibly resulting in a brake fluid leak. A brake fluid leak may lengthen the distance needed to stop the vehicle, increasing the risk of a crash.

Fix: ATI will notify owners and will replace the supercharger brackets, free of charge.

The affected vehicles, equipped with an eight-speed automatic transmission and a monostable gear selector, may not adequately warn the driver when driver's door is opened and the vehicle is not in PARK, allowing them to exit the vehicle while the vehicle is still in gear. Drivers thinking that their vehicle's transmission is in the PARK position may be struck by the vehicle and injured if they attempt to get out of the vehicle while the engine is running and the parking brake is not engaged.

Fix: Chrysler will notify owners, and dealers will update the vehicle software to mitigate the risk of vehicle rollaway, free of charge. Note: On October 19, 2016 Chrysler identified some previously repaired vehicles did not receive the complete software updates.

In the affected vehicles, the left front brake caliper may crack due to being made from an incorrect material. A cracked brake caliper may lengthen the distance needed to stop the vehicle and increase the risk of a crash.

Fix: Chrysler will notify owners, and dealers will inspect the front left brake caliper and depending on its casting date, replace it, free of charge. The recall is expected to begin on May 12, 2016.

The affected vehicles may be equipped with rear lower control arms that may have been incorrectly heat treated. This may cause the rear lower control arm to fracture. If the rear lower control arm fractures it may result in a change in ride height, loss of rear end stability, and reduced braking capabilities, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will inspect and if necessary replace the lower control arms, free of charge. Note: This supersedes Recall No.

The affected vehicles are equipped with radios that have software vulnerabilities that can allow third-party access to certain networked vehicle control systems. Exploitation of the software vulnerability may result in unauthorized remote modification and control of certain vehicle systems, increasing the risk of a crash.

Fix: Chrysler will notify and mail affected owners a USB drive that includes a software update that eliminates the vulnerability, free of charge. Optionally, owners may download the update to their own USB drive from http://www.driveuconnect.com/software-update/ or take their vehicle to a Chrysler dealer for immediate installation.
