Top issues to watch for

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

Dangerous
Brake flexible hose deterioration
XR10/201990–199960k–150k miles
The first-generation Previa suffers from premature brake flexible hose failure, with MOT data showing failure rates 24.9x higher than the fleet average on 2.4L petrol variants. The rubber brake hoses connecting the brake lines to the front calipers deteriorate internally, causing restriction or complete blockage. This is a dangerous defect that can cause brake failure or uneven braking force between wheels.
What happens if ignoredBrake hose failure can cause complete loss of braking on the affected circuit or cause brakes to bind on. Internal collapse restricts brake fluid flow, reducing braking efficiency and potentially causing brake fade. Complete failure results in brake fluid loss and severely compromised stopping ability. The vehicle should not be driven with suspected brake hose deterioration.

Suspension ball joint and bush wear
XR10/20, XR301990–200660k–120k miles
The Previa's front suspension uses ball joints and control arm bushes that wear significantly faster than the fleet average. MOT data shows this model fails suspension component inspections at 23.1x the national rate, with peak failure rates on diesel variants around 80,000-100,000 miles. The issue affects both upper and lower ball joints plus control arm bushes. Worn components cause steering instability and uneven tyre wear patterns.
What happens if ignoredWorn ball joints can separate completely, causing loss of steering control and wheel collapse. Even moderate wear causes poor handling, increased tyre wear, and MOT failure. Replacement typically requires both sides to be done together for even handling characteristics.

Engine mounting failure (XR30)
XR302000–200680k–150k miles
The rubber-to-metal bonded mounts separate or tear, allowing excessive engine movement during acceleration and deceleration. This affects driving refinement and can stress other components including exhaust connections and radiator hoses.
What happens if ignoredBroken engine mounts cause increased vibration, harsh gear changes, and potential damage to exhaust systems, cooling hoses, and electrical connections. In extreme cases, excessive engine movement can cause radiator damage or exhaust system failure. The vehicle remains driveable but should be repaired promptly to prevent secondary damage.

Emissions system deterioration (XR10/20)
XR10/201990–1999100k–200k miles
First-generation 2.4L petrol Previas show extremely high emissions failure rates in MOT testing, with levels exceeding default limits at The catalytic converter loses efficiency over time, and the engine management system struggles to maintain proper air-fuel ratios. Age-related deterioration of oxygen sensors and carbon buildup in the intake system contribute to emissions failures.
What happens if ignoredEmissions failures result in MOT failure and prevent legal road use until repaired. Catalytic converter replacement is expensive, and underlying engine problems causing rich running or oil burning may require additional work. Poor emissions performance also indicates reduced fuel economy and potential engine wear issues.
