Jeep Grand Cherokee (WL) Common Problems & Reliability

The WL generation Jeep Grand Cherokee marks a significant move upmarket, introducing a plug-in hybrid (4xe) powertrain to the UK to challenge the likes of the Volvo XC90 and BMW X5 PHEV. It features a dramatically improved, tech-laden interior with multiple screens and high-end materials, alongside a much sharper exterior design. In the UK, it aims to capture premium buyers seeking a blend of zero-emission commuting capability and legendary Jeep off-road prowess. Early reliability signs are positive, though the complexity of blending a turbocharged petrol engine with an electric motor and heavy battery pack requires careful maintenance. It suits affluent buyers who want a luxurious, capable SUV but want to avoid the predictable European choices.

Essential Pre-Purchase Step

Buying a used Jeep Grand Cherokee (WL)? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for Jeep Grand Cherokee (WL) Buyers

Test the transition between electric and petrol power in the 4xe hybrid system; it should be relatively seamless.
Check the operation of the passenger-side dashboard display (if optioned) to ensure it functions correctly.
Inspect the charging port flap and ensure the vehicle accepts a charge without throwing electrical error codes.
Verify that all ADAS features, including the night vision camera if fitted, operate without warning lights.
Test the air suspension system on rough surfaces to ensure it provides the expected luxury ride quality without knocking.
Ensure the vehicle has received the latest software updates, as the highly digitized cabin relies heavily on current firmware.
