Top issues to watch for
The most serious Peugeot 4007 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Suspension ball joint severe wear (4007)
The front suspension ball joints on the 4007 show exceptional wear rates compared to the UK fleet average, with MOT data showing failures at 19.3 times the national rate at 80-100k miles. This is a structural joint failure that creates serious risk of wheel detachment. The 4007 shares its platform with the Mitsubishi Outlander and Citroen C-Crosser, and all three models show similar premature ball joint wear patterns. The worsening trend in MOT data suggests this is an inherent design weakness rather than age-related deterioration.
What happens if ignoredBall joint failure can result in complete loss of steering control and wheel detachment, creating extreme danger to occupants and other road users. The vehicle should not be driven if ball joint wear is suspected. Replacement requires specialist equipment for pressing joints in and out of control arms.

Dangerous
Structural corrosion near subframe mountings (4007)
6 times the average. This indicates systematic corrosion affecting load-bearing structure around the subframe and suspension mounting points. As a tall SUV with higher centre of gravity, structural integrity is critical for safe handling and crashworthiness. The worsening trend suggests this affects most examples as they age.
What happens if ignoredStructural corrosion in prescribed areas represents a fundamental safety risk. The vehicle may fail to protect occupants in a crash and could suffer suspension component detachment. MOT failure is mandatory and the vehicle cannot be driven until structural repairs are completed by a certified welding specialist.

Dangerous
Brake pipe corrosion (4007)
The 4007 shows brake pipe corrosion at 4.3 times the UK fleet average across all mileage bands from 40k miles upward, with a worsening trend over the 2020-2024 MOT data period. This affects the steel brake lines that carry hydraulic pressure from the master cylinder to the brake calipers. The high failure rate suggests inadequate corrosion protection on the brake line coating or routing through areas prone to salt and moisture retention.
What happens if ignoredBrake line failure results in immediate loss of braking ability and represents extreme danger. Even minor corrosion can lead to sudden catastrophic failure under braking pressure. The vehicle should not be driven if brake line corrosion is suspected. Complete brake system replacement may be required on high-mileage examples.

Major
Front suspension dust cover deterioration (4007)
The 4007 shows extreme rates of suspension joint dust cover deterioration, with MOT failures at 25.3 times the UK fleet average at 40-60k miles. These rubber boots protect ball joints and CV joints from dirt and moisture ingress. When they fail prematurely, they accelerate wear of the expensive joints they protect. The worsening trend indicates this is a systematic material quality issue affecting the entire model range, likely related to the rubber compound specification used.
What happens if ignoredFailed dust covers allow dirt and water to contaminate suspension joints, accelerating wear and leading to premature joint failure. While not immediately dangerous, deteriorated boots rapidly lead to expensive ball joint replacement. Early replacement of boots can prevent more costly joint replacement.
