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.

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.

Some 6L engines may have a fuel rail crossover tube damaged during assembly. Over time this can cause a fuel leak, and fuel near an ignition source can start a fire.

Fix: The dealer will inspect the engine for damage to the fuel rail crossover tube and replace it if needed, at no cost to you.

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.

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.
