Which Sx4 are you looking at?

Each Sx4 generation has its own weak spots. Pick the one you’re viewing to see what to check.

  1. Brake pipe corrosion

    Safety risk GY, JY

    Brake pipes on SX4 models suffer from accelerated corrosion, particularly on the rear axle where pipes run close to road spray and salt exposure. MOT data shows this model fails brake pipe inspections at 506.8x the national fleet average, with the highest failure rate on 2.0 diesel variants at 20-40k miles. The corrosion typically begins at pipe joints and brackets where water collects, progressing to dangerous thinning of the pipe walls.

    What to check: Inspect all visible brake pipes running along the underside from front to rear, paying particular attention to areas where pipes are clipped to the body or pass through brackets. Look for any brown staining, surface rust, or white corrosion deposits on the metal pipes - these indicate active corr...

  2. Suspension component corrosion

    Wear item GY, JY

    Suspension components, particularly front lower arms and rear trailing arms, suffer from structural corrosion that can compromise safety. MOT data shows 23.7x higher failure rate than the fleet average, peaking on 1.6 petrol variants at 100-120k miles. The corrosion is most severe where suspension arms meet their mounting points and around bushes, where water and salt accumulate.

    What to check: Inspect the front lower suspension arms visible through the wheel wells for rust, flaking metal, or obvious structural damage. Look at the rear suspension trailing arms and mounting points for similar corrosion - these are visible from underneath at the rear. Check around rubber bushes for rust s...

  3. Coil spring fracture

    Wear item GY, JY

    Coil springs on SX4 models are prone to fracturing, with MOT data showing 88.2x the fleet average failure rate, peaking on 2.0 diesel variants at 20-40k miles. The fractures typically occur at the spring ends where stress concentration is highest, and can happen relatively early in the vehicle's life. This affects ride quality and can damage tyres through altered suspension geometry.

    What to check: Visually inspect all four coil springs through the wheel wells, looking for any obvious breaks, cracks, or separated coils. Check if the vehicle sits level - a dropped corner can indicate a fractured spring. Look for any sharp edges or protruding spring ends that might indicate a recent fracture....

  4. Brake hose ferrule corrosion

    Safety and MOT risk GY, JY

    The metal ferrules (crimped end fittings) on flexible brake hoses corrode heavily on SX4 models, with MOT data showing 506.8x the fleet average failure rate. The corrosion typically occurs where the metal ferrule meets the flexible hose, creating a weak point that can lead to brake fluid leaks. This is separate from but often occurs alongside the brake pipe corrosion issue.

    What to check: Locate the flexible brake hoses at each wheel (these connect the metal brake pipes to the brake calipers) and inspect the metal ferrule fittings at each end. Look for rust, corrosion, or white crystalline deposits around these fittings. Check for any signs of brake fluid weeping or staining aroun...

  5. Brake pedal anti-slip pad wear

    Safety and MOT risk GY, JY

    The rubber anti-slip pad on the brake pedal wears smooth or detaches completely on SX4 models, with MOT data showing 52.9x the fleet average failure rate, particularly affecting 1.0 and 1.4 Boosterjet variants from the S-Cross generation. While not affecting braking performance, this creates a slip hazard in wet conditions and is an MOT failure point.

    What to check: Check the brake pedal rubber pad for wear, smoothness, or complete absence. Feel the pedal surface with your hand - it should have a textured, grippy surface rather than being worn smooth. Check if the pad is loose or has detached from the pedal. Ensure the pedal face provides adequate grip for s...

What the check includes

Sx4 questions

Is the Suzuki Sx4 reliable?

21.6% of Sx4 models fail their MOT based on 148,075 tests analysed. That’s about average for the class. There are 5 known problems to watch for, the most serious being brake pipe corrosion. A full history check shows whether a specific car has had related write-offs or insurance claims.

What are the main problems with a Suzuki Sx4?

The most serious known issues are brake pipe corrosion, suspension component corrosion, coil spring fracture. Problems vary by generation, so check which apply to the year you’re looking at. Our car check flags whether a specific Sx4 has been written off or had insurance claims linked to these faults.

How do I check if a Suzuki Sx4 has outstanding finance?

Enter the registration on this page. We query Experian’s finance database and return any outstanding agreements within a minute. If finance is still owed, the finance company can legally repossess the car even after you’ve paid the seller. At £7.49 it’s the cheapest way to avoid a car that isn’t legally for sale.

How do I check if a Suzuki Sx4 has been written off?

Our check queries Experian’s insurance write-off database for Cat A, B, S and N markers. A Cat S or N Sx4 has been structurally or non-structurally damaged and repaired. This doesn’t mean it’s unsafe, but it affects resale value and some insurers won’t cover it. The check costs £7.49.

Can I check a Suzuki Sx4 for free?

You can check MOT history free on GOV.UK, which shows past test results and advisories. What it won’t show is outstanding finance, write-offs or theft markers, which are the things that actually cost you money after you’ve bought. Our full check adds all of that for £7.49, using Experian data.

Is a Suzuki Sx4 HPI check worth it?

HPI is one brand of car check. Our check uses the same Experian data covering finance, stolen, write-off and keeper history, plus MOT analysis and known Sx4 faults that HPI doesn’t include. At £7.49 it’s typically less than half the price of an HPI check.

What does a Suzuki Sx4 fail its MOT on?

The most common MOT failure on the Sx4 is emissions failure. 21.6% of Sx4 models fail overall, based on 148,075 tests. Checking a car’s full MOT history before buying shows you recurring problems the seller might not mention.
