Known issues on the 2018 Grand Cherokee. Five recalls are on federal record for this model year: an emission-control fault that allows combustion in the intake manifold and increases the risk of a fire, a front underhood wiring problem that can cause a vehicle stall and a crash risk, an antilock/traction-control brake fault that lets the vehicle start and shift out of Park without the brake pedal applied, a diesel fuel-pump issue where fuel starvation can cause an unexpected loss of drive power and a crash risk, and an engine fault that can cause the engine to stall and a crash risk. Owners have filed 1,179 complaints and Jeep has issued 399 technical service bulletins for the year.

From a routine service to a hard-to-trace electrical fault, you stay on the right year-specific numbers for your 2018 Grand Cherokee instead of cross-referencing the wrong generation.
