2018 Jeep Grand Cherokee Problems

A malfunction in the antilock-brake system (ABS) module may incorrectly illuminate the brake lights and disable the ABS and electronic stability control (ESC). In addition, the vehicle operator may be able to start and shift out of Park without the brake pedal being applied. A vehicle that can be started and shifted out of Park without applying the brake pedal can result in a vehicle rollaway. Disabled ABS and ESC systems can reduce vehicle handling and control in certain driving situations. Brake lights that incorrectly illuminate can fail to properly indicate the driver's intention to following traffic. Any of these scenarios can increase the risk of a crash.

Fix: Dealers will replace the integrated pressure transducer and update the ABS module software, as necessary free of charge. This recall replaces previous recall number 22V-426.

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.

A malfunction in the antilock-brake system (ABS) module may illuminate the brake lights, and allow the vehicle to start and shift out of Park without the brake pedal being applied. A vehicle that starts and shifts out of Park without applying the brake pedal can result in vehicle rollaway, increasing the risk of a crash without prior warning and/or injury to others outside of the vehicle.

Fix: This recall is replaced by NHTSA recall number 24V838. Vehicles already repaired under this recall will need to have the new remedy completed.

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.

The driver's floor mat may have insufficient clearance between the mat and the accelerator pedal, possibly preventing the pedal from returning to the idle position. If the floor mat prevents the accelerator pedal from returning to idle, there would be an increased risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace any of the affected floor mats, free of charge.

These floor mats may have insufficient clearance between the mat and the accelerator pedal, possibly inhibiting the pedal from returning to an idle position. If the floor mat prevents the accelerator pedal from returning to idle, there would be an increased risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace any of the affected floor mats, free of charge.

The powertrain control module may be equipped with a voltage regulator chip in the circuit board that may fail, causing a stall or a no start condition. A vehicle stall can increase the risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace the powertrain control module, 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.

An incorrect transmission park lock rod may have been installed in the transmission. If the incorrect park lock rod is installed, the transmission may not shift into 'PARK' and keep the vehicle from moving, increasing the risk of unintended vehicle movement and the risk of a crash.

Fix: Chrysler will notify owners, and dealers will install the correct park lock rod, free of charge.

2L Supercharged Engine. The fuel line may separate. If the fuel line separates, the engine may stall, increasing the risk of a crash. In addition, a fuel line separation increases the risk of an engine compartment fire and injury.

Fix: Chrysler will notify owners, and dealers will inspect and, as necessary, replace the fuel line, free of charge.
