Buying a used Jeep Grand Cherokee: what to check

These checks follow the Jeep Grand Cherokee’s own MOT record: the areas it fails on most often, and how that changes as the car gets older. None of them replaces a mechanic’s inspection, but they tell you where to look first.

The biggest drop in pass rate for the Jeep Grand Cherokee comes between 10–15 years and 15+ years old, from 81.9% to 70.7%. If you are looking at one in or just past that range, read its MOT history closely.

By mileage, the steepest fall is from 60,000–90,000 mi to 90,000–120,000 mi: 84.9% down to 77.4%. Mileage matters as well as age, so compare the car’s recorded mileages with its year.

  1. 1. Lights and electrics

    Recorded in 51.5% of failed Jeep Grand Cherokee MOTs. 22.6% of tests at 15+ years failed on lights and electrics, against 9.6% at 3–6 years.

    Walk round with the lights on: headlights (dipped and main), indicators, brake lights, fog light and number-plate lamp. Check the dashboard warning lights come on with the ignition, then go out once the engine starts.

  2. 2. Brakes

    Recorded in 46.8% of failed Jeep Grand Cherokee MOTs. 17.0% of tests at 15+ years failed on brakes, against 4.4% at 3–6 years.

    On the test drive, the car should stop straight without pulling or juddering, and the handbrake should hold it on a slope. Look through the wheels for scored or heavily lipped discs.

  3. 3. Suspension

    Recorded in 30.9% of failed Jeep Grand Cherokee MOTs. 19.8% of tests at 15+ years failed on suspension, against 0.7% at 3–6 years.

    Listen for knocks over bumps and speed humps, and check the car sits level. Push down on each corner: it should settle rather than keep bouncing.

  4. 4. Tyres

    Recorded in 15.6% of failed Jeep Grand Cherokee MOTs. 4.1% of tests at 10–15 years failed on tyres, against 1.8% at 3–6 years.

    Check tread depth across the whole width of every tyre, including the inner edge. Uneven wear can point to alignment or suspension problems. Look for cuts and bulges in the sidewalls.

  5. 5. Windscreen and wipers

    Recorded in 15.6% of failed Jeep Grand Cherokee MOTs. 6.2% of tests at 15+ years failed on windscreen and wipers, against 2.9% at 3–6 years.

    Look for windscreen chips and cracks in the driver’s line of sight, and check the wipers clear the screen and the washers work.

Check the car’s own MOT history. Averages describe the model, not the car in front of you. Look up its registration for past failures, advisories that were never fixed, and gaps or dips in the recorded mileage.

Ask for the service history. Invoices show what was done and when; a stamp alone shows less. See how to check Jeep service history and what a service history check can tell you.
