The Totally Integrated Power Module (TIPM) can fail, causing various electrical issues including fuel pump relay problems (no start), random horn honking, and erratic behavior of lights and accessories. Repairs typically run $800-$1,500. Severity: high.
Certain 2012-2014 Jeep Grand Cherokee vehicles are covered by alternator-diode safety recalls P60 / NHTSA 14V-634 or T36 / NHTSA 17V-435. P60 covers specified 3.6L vehicles with a 160A alternator. T36 covers VIN-included WK vehicles with electro-hydraulic power steering and speci… Repairs typically run $0-$0. Severity: high.
The integrated engine oil cooler/oil-filter housing on the 3.0L EcoDiesel develops internal failures that let engine oil and coolant cross-contaminate — owners report 'milkshake' oil and oil in the coolant bottle. Casting debris left in the engine can become trapped in the cooler… Repairs typically run $500-$4,000. Severity: high.
The 2014-2015 Grand Cherokee uses a ZF monostable electronic 'E-shift' gear selector that always returns to a center position regardless of selected gear, giving poor tactile/visual feedback. NHTSA tied it to over 300 rollaway incidents and 117 crashes after drivers believed they… Repairs typically run $0-$0. Severity: high.
Certain 2014-2019 Jeep Grand Cherokee vehicles with the 3.0L EcoDiesel engine are included in safety recall W79 / NHTSA 20V-699. NHTSA lists 28,884 potentially involved Jeep vehicles. Thermal fatigue can cause the EGR cooler to crack internally over time, allowing pre-heated vapo… Repairs typically run $0-$0. Severity: high.
Grand Cherokees with electro-hydraulic power steering subject the alternator to cyclical electrical loads that cause thermal failure of the internal diodes. The alternator can fail suddenly, stalling the vehicle without warning and, in some cases, short-circuiting and causing an… Repairs typically run $0-$700. Severity: high.
Recall 18V332000 covers 2014-2018 Jeep Grand Cherokee models among a long list of FCA vehicles. The defect is in the cruise control system: a short circuit in the vehicle's wiring can leave the cruise control unable to be disengaged once it has been set. According to NHTSA, the d… Severity: high.
A persistent tick and cylinder misfire on a 5.7L Grand Cherokee can be consistent with valvetrain damage, but those symptoms do not identify a failed MDS lifter or worn camshaft by themselves. Exhaust-manifold leaks, ignition or injector faults, oil-pressure problems, rocker/push… Severity: high.
Certain 2014-2020 Jeep Grand Cherokee (WK) vehicles with the 3.0L diesel engine are included in safety recall Z46 / NHTSA 22V-406.

The ZF 8HP 8-speed automatic transmission can exhibit harsh shifts, hesitation, or erratic behavior. Some owners report the transmission hunting between gears or feeling like it's in the wrong gear for the driving conditions. Repairs typically run $150-$2,500. Severity: medium.
The water pump on the 3.6L Pentastar V6 can fail, causing coolant leaks and overheating. The pump is internal and driven by the timing chain, making replacement labor-intensive. Failure often occurs between 80,000-120,000 miles. Repairs typically run $800-$1,800. Severity: medium.
Oil found around the Pentastar oil filter adapter does not prove that the complete adapter or oil cooler has cracked. FCA's service guidance separates several repair paths: a cap O-ring that is cut, damaged, or installed in the wrong groove; five adapter bolts that are not at the… Severity: medium.
The electronic-throttle-control warning lamp and reduced-power or limp mode are protective responses, not a diagnosis that the throttle body has failed. Depending on the stored DTC and application, the factory path may lead to a stuck or contaminated throttle plate, throttle moto… Severity: medium.
A DEF/SCR warning or reductant-system DTC on a 2014-2016 Grand Cherokee EcoDiesel does not prove that the complete DEF tank has failed. FCA documentation shows materially different causes and remedies within this model range: one defined 2015 population received PCM software and… Severity: medium.
The 2014-2015 Jeep Grand Cherokee is one of the vehicles covered by FCA US LLC's radio software recall. The radios in these Grand Cherokees have software vulnerabilities that can allow third-party access to certain networked vehicle control systems. According to NHTSA, exploiting… Severity: medium.
Uconnect resets or a blank screen, intermittent accessories, a discharged battery, and communication faults may occur together, but they do not establish that the Body Control Module is defective. Radio software or hardware, a weak battery or charging problem, poor power or groun… Severity: medium.
A WK2 front-end clunk over bumps, during braking, or while steering can come from more than the sway-bar links or lower control arms named in the old card. The source can vary with loading and may involve a stabilizer link or bushing, control-arm bushing, ball joint, tie-rod end,… Severity: medium.
Grand Cherokee 4x4 differentials (and the transfer case) are a known spot for pinion-seal leaks — owners find gear oil weeping where the driveshaft meets the diff, leaving puddles and, if ignored, running the diff low on lube. A low/contaminated differential then produces a speed… Repairs typically run $150-$900. Severity: medium.
WK2 Grand Cherokees commonly develop a speed-dependent driveline vibration or shudder felt through the floor/seat, typically appearing around 45-75 mph and often worse under light acceleration or on deceleration.
