Top issues to watch for
The most serious Toyota Auris problems ranked by severity. We track 9 known issues — here are the ones you need to know about first.
Dangerous
Subframe corrosion and structural weakness (E150)
The E150 Auris suffers from severe corrosion of the rear subframe mounting points and load-bearing structure within 30cm of suspension component attachments. MOT data shows this model fails at up to 26.9 times the fleet average for prescribed area structural failure, with suspension components becoming excessively corroded at 44.9 times the fleet average. The thin steel construction and poor rust protection in these areas leads to structural weakness that compromises vehicle safety. Later E150/E180 models have improved corrosion resistance but are not immune.
What happens if ignoredStructural failure of subframe mounting points can cause loss of vehicle control, particularly under heavy braking or cornering. Suspension components may detach from the vehicle body. Repair typically requires subframe replacement and welding work costing £1,500-£3,000. Cars with significant structural corrosion may be uneconomical to repair.

Dangerous
Brake pipe corrosion (E150)
First-generation Auris models suffer from accelerated brake pipe corrosion, particularly affecting the rear brake lines that run along the corroding subframe. MOT data shows this model fails at 17.4 times the fleet average for brake pipe damage or excessive corrosion. The brake pipes are vulnerable to damage from debris and corrosion products falling from the deteriorating subframe above them, creating a cascading failure mode unique to this generation.
What happens if ignoredBrake pipe failure results in sudden loss of braking ability on the affected circuit. Even minor leaks allow air into the system, reducing braking effectiveness. Complete brake failure can occur without warning. Replacement of corroded brake pipes costs £300-£800 depending on how many sections require renewal.

Major
DPF issues
Diesel Auris models suffer from diesel particulate filter blockage, particularly when used predominantly for short urban journeys that prevent the DPF reaching the temperature required for passive regeneration. The 1.4 and 1.6 D-4D engines are especially susceptible, with MOT data showing diesel variants fail emissions tests at
What happens if ignoredA completely blocked DPF prevents the engine from running properly and triggers limp mode. Professional DPF cleaning costs £300-£600, while replacement costs £800-£1,500. Cars that fail to complete regeneration cycles may suffer turbocharger damage from excessive exhaust back-pressure.

Major
Injector failure
Diesel injectors on Auris models are prone to failure due to contamination from poor fuel quality and carbon build-up from DPF regeneration cycles. The high-pressure common rail system operates at up to 1,800 bar, making the injectors vulnerable to wear from contaminated diesel fuel. Failed injectors cause rough running, increased emissions, and can damage other engine components if left untreated.
What happens if ignoredFailed injectors cause poor fuel economy, increased emissions, and potential damage to the catalytic converter or DPF. Individual injector replacement costs £150-£300 per injector plus labour. Complete set replacement can cost £800-£1,200. Continuing to drive with failed injectors risks expensive damage to other emission control components.
