The 2.4L Tigershark MultiAir engine suffers from defective piston rings allowing oil to burn in combustion chamber. Owners report consuming 1 quart per 1,000 miles. Engine can stall when oil falls below 3.5 quarts without warning light. Repairs typically run $0-$8,500. Severity: high.
The ZF 948TE 9-speed automatic transmission exhibits harsh shifting, delayed engagement, and unexpected shifting into neutral. Early models (2014-2015) experienced the most severe issues. The transmission can unexpectedly shift into neutral while driving, creating a crash risk. Repairs typically run $0-$6,500. Severity: high.
Multiple factors cause sudden engine stalling including low oil levels (2.4L), VVT issues, faulty sensors, fuel system problems, and transmission-related stalling (2019 9-speed). Stalling typically emerges after ~1,000 miles. Repairs typically run $0-$2,500. Severity: high.
The Totally Integrated Power Module fuel pump relay fails, causing no-start conditions or fuel pump running continuously. Unlike older models, the relay is integrated and cannot be replaced separately. Repairs typically run $75-$2,000. Severity: high.
The plastic oil filter housing and cooler assembly on Pentastar V6 engines develops leaks due to thermal cycling. The plastic warps, becomes brittle, and cracks over time from constant engine heat exposure. Repairs typically run $700-$1,500. Severity: medium.
Controller Area Network electrical system experiences communication failures between modules, triggering multiple warning lights and system failures simultaneously. Common codes U0001 and U0131 indicate wiring harness breaks or connector corrosion. Repairs typically run $150-$2,000. Severity: medium.
Sunroof drain tubes become clogged with debris, causing water to overflow into cabin. Drain hoses can become kinked or detached, allowing water into headliner. Leads to water damage, mold, electrical issues. Repairs typically run $0-$900. Severity: medium.
Front brake rotors warp prematurely (often around 25,000 miles) due to heat management issues. Soft rotors combined with harder pads and thermal cycling causes excessive wear. Corroded caliper slide pins worsen problem. Repairs typically run $250-$800. Severity: medium.
Moisture accumulates inside headlight housings due to vent holes designed for manufacturing. While FCA considers minor condensation normal, excessive moisture or water droplets indicate seal failure. Repairs typically run $0-$1,200. Severity: low.
