The Jeep Grand Cherokee is a comfortable, capable SUV, but it has had a string of expensive issues: Pentastar V6 cylinder head failures, Hemi MDS lifter problems, electronic shifter recalls, and air suspension failures on Summit trims. Knowing what to avoid matters.
The 2011-2013 3.6L Pentastar V6 has documented cylinder head failures (rocker arm and head replacement). The 5.7L Hemi MDS lifter and air suspension issues are also common.
Early Pentastar V6 cylinder heads suffered from a failed valve seat and rocker arm issues, often causing a tick or misfire on cylinder 2 or 4. Stellantis extended warranties; head replacement is the fix.
View P0302 Diagnosis →Multi-Displacement System lifters collapse, similar to the GM AFM issue. Camshaft damage often follows. MDS-disable tunes are popular preventive measures.
View P0300 Diagnosis →The 8-speed transmission has hesitation, harsh shifts, and the infamous monostable shifter recall. Many issues are software fixable, some require valve body or full rebuild.
View P0700 Diagnosis →Air struts and compressors fail, causing the vehicle to sag or lose height entirely. Conversion kits to coil springs are popular alternatives.
Run free diagnosis →The monostable shifter caused vehicles to roll away after being parked - a major recall after high-profile incidents. Confirm recall is complete before buying.
Run free diagnosis →The TIPM controls power distribution and is a known failure point on early WK2 Grand Cherokees, causing random electrical gremlins, no-start, and stalling.

2011-2013 (3.6L Pentastar cylinder heads, TIPM failures), 2014-2015 (electronic shifter recall, 8-speed transmission complaints)
2018-2020 Grand Cherokee with the updated 3.6L Pentastar and refined 8-speed software. The Trailhawk and Limited trims tend to age better than the air-suspended Summit.
Plan for $800-1,400/year in maintenance and $6,000-12,000 in lifetime non-routine costs (transmission service, suspension, lifters). Air suspension models add significant cost.
If your Grand Cherokee is throwing a check engine light, these are the codes most often associated with the problems above. Click any code for full diagnosis steps and typical repair costs.
It depends on year and condition. Avoid 2011-2013 Pentastars (cylinder head issue) and 2014-2015 with shifter and transmission problems. The 2018-2020 WK2 with the updated Pentastar is a much better bet.
2018-2020 Grand Cherokee with the 3.6L Pentastar and 8-speed (post-software refinement). Avoid air suspension if you can - the steel-spring trims are far more reliable.
The post-2014 3.6L Pentastar V6 is the most reliable choice. The 5.7L Hemi has MDS lifter risk. Avoid the EcoDiesel due to emissions and reliability complaints.
Yes, especially compared to Asian competitors. Air suspension, complex 4WD, and engine quirks lead to $800-1,400/year average maintenance costs.
A well-maintained Pentastar V6 model can reach 200,000 miles. Air suspension and MDS lifter risks shorten the practical lifespan unless preventive maintenance is done.
