Reliability report · 2020 Jeep Grand Cherokee · Updated July 2026

The quietest and most sorted WK2 year — a short recall list and the fewest complaints, though the 3.6L valvetrain check still earns its keep.

The 2020 is the last full model year of the WK2 before the redesign, and it's the calmest one in our data — 224 complaints against 837 for 2018 and 356 for 2019, with only three recalls. The platform is fully mature; a mechanic's take on the generation is that 'many of them are minor and many of the bigger ones are covered under warranty or the dealer will cover them.'

That's not a free pass. The 3.6L Pentastar's rocker-and-camshaft wear is a lifetime-of-the-engine pattern, so the top-end-tick and misfire-scan check still applies. And on a 3.0L EcoDiesel, the high-pressure-fuel-pump recall (22V-406) and tone-wheel recall (23V-411) reach into 2020. But as a used buy, this is the WK2 to hunt for — provided the valvetrain is clean and the diesel recalls, if applicable, are done.

Canary status

Calm

What that means: 224 federal complaints — the lowest in our Grand Cherokee data — and just three recalls. The final full year of the mature fourth-generation (WK2) platform: the redesign-era problems are behind it, and what's left is the familiar 3.6L valvetrain check plus a couple of software and diesel recalls. Calm here means no expensive pattern unique to the year, not that you skip the inspection.

3.6L Pentastar valvetrain — the one lifetime check that stays

moderate
  • 3.6L Pentastar V6

Even on the calmest WK2 year, the 3.6L Pentastar V6's rocker arms and camshaft lobes are the wear item to check. The tell is a top-end tick that can become a misfire; a teardown mechanic quotes $1,000 to $2,000 to fix the rockers early, more if it spreads, and Chrysler's service bulletins cover the valvetrain-noise condition across these years. It shows up far less in the 2020 file than in 2018, but it's the same engine — listen for the tick and scan for misfire codes.

This is a 3.6L Pentastar V6 problem. The 3.0L EcoDiesel V6 and 5.7L HEMI V8 don’t share it.

3.0L EcoDiesel — fuel pump and tone wheel recalls reach 2020moderate

  • 3.0L EcoDiesel V6

On a 3.0L EcoDiesel, two recalls extend into 2020: the high-pressure fuel pump that can fail and starve the engine of fuel (22V-406, code Z46) and the crankshaft tone wheel that can delaminate and stall the engine (23V-411, code 66A, an expansion of 20V-475). Both are free. The EGR-cooler fire recall (20V-699) ended at 2019, so it does not apply here. Verify the two that do on any diesel.

Rearview-camera software recall — 20V-191minor

A software error can leave the rearview camera image displayed after the truck is shifted out of reverse — a distraction and a federal rear-visibility (FMVSS 111) non-compliance. Chrysler's fix is a free radio-display software update, available over-the-air. Confirm 20V-191 shows completed; it's a quick one but it's the kind of item that lingers unaddressed.

Coolant, water pump, and Uconnect — the usual WK2 checksminor

The generation's cheap-part wear items still apply: the brittle oil-filter housing, the HEMI water pump, and cracked thermostat housings — look for coolant loss between changes. The Uconnect touchscreen can delaminate as on the earlier years, though it's much less common in the 2020 file; confirm the screen responds cleanly and shows the backup camera. None of these is expensive if caught early.
