What to check before buying a 2011 Grand Cherokee Crd A
On a 2011 Grand Cherokee Crd A, lighting & signalling is what the MOT record says goes wrong most — it appeared in 12.4% of tests. Check these areas before you commit.
- Lighting & signalling (12.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.5% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (5.4% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
