2016 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.

6L engine built at the Saltillo engine plant. During the assembly of the engine, the fuel rail crossover tube may have been damaged, which, over time, may result in a fuel leak. A fuel leak in the presence of an ignition source, can increase the risk of a fire.

Fix: Chrysler will notify owners, and dealers will inspect the engine assembly for damage to the fuel rail crossover tube, replacing it as necessary, free of charge.

The brake transmission shift interlock solenoid may have a loose electrical connection which could result in a loss of solenoid function. If the solenoid loses function, the transmission may lock in the Park or Neutral position when the vehicle comes to a stop, possibly rendering the vehicle disabled in traffic, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace the shifter assembly, free of charge.

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.
