2014 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.

In some vehicles with the 6L engine and 160 amp alternator, the alternator can fail without warning. When that happens, the engine may stall while you are driving, which raises the risk of a crash.

Fix: Your dealer will replace the alternator at no cost to you.

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 had brake booster shields installed under a previous campaign to prevent water from entering the brake booster and limiting braking ability. This recall is to verify that the brake booster shield installation was performed properly. If the brake booster shield was not installed properly, the vehicle's braking ability may be reduced, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will inspect the brake booster shield, correcting the installation as necessary, free of charge.

The affected vehicles have electro-hydraulic power steering (EHPS) and are equipped with a 5.7L or a 3.6L engine and a 160, 180 or 220 amp alternator. In the affected vehicles, the alternator may suddenly fail. If the alternator fails, the vehicle may stall without warning, increasing the risk of a crash. There is also the possibility that the alternator may short circuit, increasing the risk of a fire.

Fix: Chrysler will notify owners, and dealers will inspect the alternator and depending on the part number, will replace the alternator, if necessary, 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 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.

Due to a fault within the Occupant Restraint Control (OCR) module, the frontal air bags, seat belt pretensioners, and side air bags may be disabled. The malfunction indicator light “MIL” should illuminate to initially warn drivers of a failure. If the frontal air bags, seat belt pretensioners, and side air bags are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates use of the passive restraint system.

Fix: Chrysler will notify owners, and dealers will replace the ORC module, free of charge.

A software problem in the steering column control module can turn off electronic stability control. In certain driving situations, the driver may not be able to keep the vehicle under control, which raises the risk of a crash.

Fix: The dealer will update the steering column control module software free of charge.

6L engine and a 160 amp alternator. In the affected vehicles, the alternator may suddenly fail. If the alternator fails, the vehicle may stall without warning, increasing the risk of a crash.

Fix: Chrysler has notified owners, and dealers will replace the alternator, free of charge.

After a service repair, the wiring for the sun visor vanity lamp may short circuit. A short can cause a fire, so the problem is serious.

Fix: The dealer will inspect and repair any damaged wiring and install a new sun visor that routes the wire correctly, free of charge.

When adaptive cruise control is on and you press the gas to speed up beyond what cruise would do alone, the car may keep accelerating briefly after you let go of the pedal. This unintended speeding can raise the risk of a crash.

Fix: The dealer will re-flash the Driver Assistance System Module (DASM) software at no cost to you.

The subject vehicles have a brake booster with a center shell that may corrode and allow water to get inside. The water inside could freeze and limit the braking ability of the vehicle, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will add a water diverter shield to the booster after the booster has been tested to confirm it can hold an acceptable amount of vacuum pressure. If the booster inspection confirms an unacceptable loss of vacuum pressure, the booster will be replaced.

Loose alternator ground wires and a computer communication fault can cause warning lights to flicker or go dark, and can disable anti-lock brakes and electronic stability control. Without them you have less control in a skid or emergency stop, and you may not be warned of brake or other system failures, which raises the risk of a crash.

Fix: The dealer will update the ABS and instrument cluster software and tighten the alternator ground wire, free of charge.

When the car switches between daytime running lights and parking lights, electrical spikes can turn the parking lamps off. Without them, other drivers may have a harder time seeing your vehicle, which raises the risk of a crash.

Fix: The dealer will update the Central Body Controller software at no cost to you.
