Known problems with the 2020 Jeep Grand Cherokee

1 of the 5 issues we track for the 2012–2021 generation is documented against the 2020 model year.

  • Quadra-Lift air suspension leaks and compressor failure

    moderate

    The optional/standard-on-upper-trims Quadra-Lift air suspension is prone to leaking air springs (commonly at the top shock/strut fitting) and worn-out compressors, especially as the vehicle ages, symptoms include sagging overnight, the ride height stuck in one mode, or an audible compressor running constantly trying to keep up. It's a known-quantity failure across the whole generation rather than a specific recall; some owners convert to aftermarket coil-over conversions to avoid repeat repairs.

    Typical cost: $150–$400 per air spring/strut; $800–$1,500 for a compressor

4 more issues reported in other 2012–2021 years
  • TIPM fuel pump relay failure / stall (recall) — 2012–2013 (recall population); sporadic TIPM complaints reported through the generation
  • Monostable shifter rollaway (recall) — 2014–2015
  • EcoDiesel EGR cooler cracking (recall) — 2014–2019 (EcoDiesel only)
  • Uconnect touchscreen freezes / reboots — 2012–2017 (more common on earlier Uconnect versions)

About the Jeep Grand Cherokee

The Jeep Grand Cherokee is Jeep's mid-size, unibody flagship SUV, and the 2012–2025 window covers two very different generations plus a messy handoff year. 2L supercharged Trackhawk performance flagships from 2012 and 2018 respectively. It earned a reputation for comfort and off-road ability (Quadra-Lift air suspension, Quadra-Drive II) alongside a rap sheet of electrical and recall headaches, a Totally Integrated Power Module (TIPM) that could kill the fuel pump relay and stall the engine, a monostable 8-speed shifter that let cars roll away because drivers didn't feel it click into Park, and (on the EcoDiesel) a cracked-EGR-cooler recall layered on top of the wider FCA/VM Motori diesel-emissions settlement.

6L only. 0L turbo-four 4xe plug-in hybrid rated around 25 miles of EV range. Jeep dropped the HEMI V8 from the 2-row Grand Cherokee after the 2023 model year, leaving just the Pentastar and 4xe for 2024–2025 (the inline-six "Hurricane" that replaced the V8 elsewhere in the Stellantis lineup did not come to the 2-row Grand Cherokee in this window).

The WL's early years brought their own recalls: a steering intermediate shaft that could disconnect, rear coil springs that could detach while driving, and, on 4xe models, a serious high-voltage battery fire recall that told owners to park outside. Across both generations the 12V battery lives in the cabin, not the engine bay (under the front passenger seat on WK2; split between a main battery under the driver's seat and a small auxiliary start-stop battery under the passenger seat on WL), which trips up a lot of first-time DIYers expecting to pop the hood.

For how the specifications changed across every generation, see the full Jeep Grand Cherokee guide.
