Toyota Proace MOT Failures
An analysis of 116,720 real DVSA MOT tests on the Toyota Proace — what fails, how often, and how that compares to every other car on UK roads. Generations covered: Gen1 (2013–2017), Gen2 (2018–2023).
Where the Toyota Proace fails its MOT
The single biggest MOT failure point on the Toyota Proace is brake pedal anti-slip provision missing, loose ... — this model is 26 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 116,720 MOT tests, 0.62% of all Toyota Proace tests recorded this as a failure.
Brake failures on the MOT range from worn pads and discs (routine maintenance) to corroded brake lines and seized calipers (more serious). Check for any pulling under braking and listen for grinding.
Other notable weak points include lamp missing, inoperative or in the case of a m... (97x the fleet average), power steering fault (16x the fleet average), tyre has a lump, bulge or tear caused by separa... (9.1x the fleet average), and engine mounting/bracket severely damaged or det... (8.4x the fleet average). These ratios compare the Toyota Proace's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 6 categories: Brakes, Lights & Electrics, Steering, Tyres, Bodywork and others. If you're inspecting a Toyota Proace before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Toyota Proace's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Toyota Proace specifically, the DVSA data shows the most common failures at this mileage are light unit fault (31x the average) and brake pedal anti-slip provision missing, loose ... (26x). lamp missing, inoperative or in the case of a m... (26x) and rear registration plate lamp does not illuminat... (18x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Toyota Proace specifically, the DVSA data shows the most common failures at this mileage are lamp missing, inoperative or in the case of a m... (89x the average) and power steering fault (16x). brake pedal anti-slip provision missing, loose ... (16x) and transmission joint, belt or chain worn (9.3x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Toyota Proace specifically, the DVSA data shows the most common failures at this mileage are lamp missing, inoperative or in the case of a m... (97x the average) and brake pedal anti-slip provision missing, loose ... (14x). power steering fault (13x) and engine mounting/bracket severely damaged or det... (7.5x) also appear frequently.
The shift from light unit fault at lower mileages to lamp missing, inoperative or in the case of a m... at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Toyota Proace specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Brake pedal anti-slip provision failure Dangerous
The brake pedal rubber pad degrades, becomes loose, or wears smooth at extraordinarily high rates on the ProAce, failing MOT tests at 36 times the national fleet average. Affects Gen1, Gen2; typical independent garage repair cost is £15–£30.
CV joint boot failure - premature deterioration Major
The constant velocity joint protective boots on the ProAce fail at significantly higher rates than the national average, with severely deteriorated boots appearing as early as 20,000 miles. Affects Gen1, Gen2; typical independent garage repair cost is £80–£120.
Power steering fluid loss and system malfunction Major
The hydraulic power steering system on first-generation ProAce models suffers from fluid leaks and pump failures at rates significantly above the fleet average. Affects Gen1; typical independent garage repair cost is £250–£400.
Engine management light - diesel emissions system faults Major
The ProAce suffers from engine management warning lights at nearly 5 times the national average, primarily related to diesel emissions system faults including DPF blockage, EGR valve problems, and NOx sensor failures. Affects Gen1, Gen2; typical independent garage repair cost is £80–£150.

What to check before buying a Toyota Proace
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Toyota Proace:
Brakes — check for brake pedal anti-slip provision missing, loose .... Lights & Electrics — check for lamp missing, inoperative or in the case of a m..., rear registration plate lamp does not illuminat.... Steering — check for power steering fault. Tyres — check for tyre has a lump, bulge or tear caused by separa....
Beyond the MOT items, ask specifically about brake pedal anti-slip provision failure and cv joint boot failure - premature deterioration. These won't show up on a standard MOT but can be expensive to fix — repairs start from £15. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
