Top issues to watch for

The most serious Toyota Avensis problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Brake pipe corrosion (T220/T250/T270)
T220, T250, T2701997–201840k–150k miles
Brake pipe corrosion is a documented safety critical issue on all Avensis generations, with MOT failure rates up to 25.3 times the fleet average. Steel brake pipes are particularly vulnerable where they pass through the rear beam and along the underside of the vehicle. Failure can result in sudden brake fluid loss and complete brake system failure. The problem is most severe on higher mileage vehicles but can occur from 40,000 miles in adverse conditions.
What happens if ignoredBrake pipe failure results in immediate loss of braking ability and presents an extreme safety risk. The vehicle should not be driven if pipe corrosion is suspected. Complete brake pipe replacement is often required once corrosion begins, as attempting to repair one section typically reveals further deterioration elsewhere.

Major
Suspension component corrosion and damage (T220/T250/T270)
T220, T250, T2701997–201820k–150k miles
Front suspension components including lower control arms, anti-roll bar links, and subframe mounting points are prone to accelerated corrosion on all Avensis generations. MOT data shows failure rates up to 53 times the fleet average, with 85,925 recorded failures over 2020-2024. The issue affects all engine variants and becomes increasingly severe at higher mileages. Later T270 models show some improvement but still exceed fleet averages significantly.
What happens if ignoredCorroded suspension components can fail suddenly, causing loss of vehicle control. Minor corrosion can be managed with regular inspection, but severely affected components require immediate replacement. Repair costs vary widely depending on how many components need replacement simultaneously.

Major
Petrol engine emissions system failures (T220/T250/T270)
T220, T250, T2701997–201860k–150k miles
Petrol Avensis models show exceptionally high emissions test failure rates, with MOT data recording up to This affects both catalyst efficiency and lambda sensor operation, particularly on 1.8-litre VVT-i and Valvematic engines. The problem becomes more severe with age and mileage, with failures concentrated above 60,000 miles. Poor fuel quality and short journey patterns accelerate the deterioration.
What happens if ignoredFailed emissions tests result in MOT failure and the vehicle cannot be legally driven on public roads. Repair typically involves replacing the catalytic converter and associated oxygen sensors, with costs potentially exceeding the vehicle's value on older examples.

Electronic parking brake malfunction (T270)
T2702009–2018120k–150k miles
Third-generation Avensis models equipped with electronic parking brake systems show failure rates 24.9 times the fleet average for parking brake malfunction indicator lights. The system uses electric motors to operate the rear brake calipers and is prone to motor failure and cable corrosion at high mileages. Failures typically manifest as inability to release or apply the parking brake, potentially leaving the vehicle immobilised.
What happens if ignoredA failed electronic parking brake may prevent the vehicle from being driven if it cannot be released, or may fail to secure the vehicle if it cannot be applied. Repair typically requires replacement of the electric motor assemblies and associated cables. The vehicle remains roadworthy with a functioning foot brake but fails MOT requirements.
