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.

A part called the crankshaft position sensor tone wheel can come apart, which may cause the engine to lose timing and stall while you are driving. A sudden stall can increase the risk of a crash.

Fix: The dealer will update the engine control software so the car can keep running by using the camshaft signal if the crankshaft signal is lost, and this repair is free.

A short in the wiring can keep the cruise control engaged even when you press the brake or turn the system off, so the car may hold its speed or speed up. This raises the risk of a crash, so stop using cruise control until the repair is done.

Fix: The dealer will update the engine or powertrain control software at no charge.

The supercharger mounting bracket may rub against and damage the ABS brake line, which can cause a brake fluid leak. Losing brake fluid can make the car take longer to stop and raise the risk of a crash.

Fix: The dealer 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.

The left front brake caliper was made from the wrong material, so it can crack. A cracked caliper can make the vehicle take longer to stop and raises the risk of a crash.

Fix: The dealer will inspect the front left brake caliper and replace it if needed, depending on its casting date, at no charge.

Some rear lower control arms may have been heat treated incorrectly, making them likely to crack or break. A broken arm can change the ride height, reduce rear stability and braking, and raise the risk of a crash.

Fix: The dealer will inspect the rear lower control arms and replace them if needed, free of charge.

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.
