Credov's researched list of the 4 faults the Jeep Grand Cherokee WK is known for (2005–2010), 4 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Check the dash for ETC and engine lights, and look for oil wetness around the intake manifold.
Why it matters: A swirl motor alone is a moderate job, but where the turbo and intake have also been damaged by oil ingestion the bill becomes very large.
What to look for: Drive hot and cold, feeling for harsh or flared shifts, and ask what the car has towed.
Why it matters: A gearbox rebuild or exchange unit is a major cost, and a car that has towed heavily with no fluid changes is a much higher risk even if it still drives normally.
What to look for: Start the car three times cold, and check the battery terminals and main cable for corrosion.
Why it matters: Intermittent electrical no-start faults are hard to diagnose and can leave the car off the road for a long time, and a WIN or TIPM replacement is a significant cost.
What to look for: Listen at idle and just off idle for a ticking or tapping noise that follows engine speed.
Why it matters: Repair is a camshaft and lifter set, and sometimes the MDS solenoids, which is a significant cost, or a replacement engine in a worse case.
