4/5 Overall
NHTSA 5-Star Safety Rating
The 2018 Jeep Grand Cherokee draws the highest complaint volume around its electrical system, which accounts for roughly a quarter of all reports filed. Owners frequently describe the UConnect infotainment screen malfunctioning on its own, changing settings, placing unintended calls, and showing signs of screen delamination. Broader electrical gremlins, including unexpected shutoffs and no-start conditions, also appear across multiple reports. Engine complaints form the next notable cluster, with owners describing internal fluid leaks that lead to engine failure and, in some cases, full replacement. Powertrain reports center on the transmission unexpectedly dropping into a low gear or entering limp mode at highway speeds, often without any warning lights, and typically resetting after the vehicle is turned off and restarted.

By System
The 2018 Jeep Grand Cherokee has 15 recalls, the most serious being a cluster of issues that can allow the vehicle to shift out of Park or roll away without warning, a fire risk from a cracked diesel EGR cooler, and a fuel line separation on supercharged models that can cause an underhood fire.
Several recalls center on the anti-lock brake system module, which can malfunction and allow the vehicle to start and move out of Park without the brake pedal being pressed; an earlier repair attempt did not fully resolve this for all affected vehicles, and a second fix is required. Related to this, an incorrect park lock rod in the transmission can prevent the gear selector from holding in Park at all.
On diesel-equipped models, a cracked EGR cooler can allow vaporized coolant into the intake manifold where it can ignite, and separately, the high-pressure fuel pump can shed debris that starves the engine of fuel. A crankshaft sensor component can also delaminate and cause the engine to stall. On supercharged 6.2L models, a fuel line can separate, cutting power and raising the risk of fire. On SRT and Trackhawk trims, the driver's floor mat can trap the accelerator pedal in a pressed position.
Electrical and software issues round out the list: front underhood wiring can cause a stall, and a cruise control software defect can prevent the system from deactivating, causing the vehicle to hold speed or accelerate against the driver's input.
