Which 944 are you looking at?

Each 944 generation has its own weak spots. Here are the known problems.

  1. Subframe mounting point corrosion

    Safety risk 944

    The rear suspension subframe mounts to the main chassis through steel brackets that are prone to corrosion from road salt and moisture retention. MOT data shows this model fails at 29x the fleet average for load-bearing structure defects near suspension mounting points. The steel used in 1980s Porsches was particularly susceptible to rust, and failure can cause the rear suspension geometry to shift dramatically during cornering or braking. This is a well-documented structural weakness across all 944 variants.

    What to check: Inspect the rear subframe mounting points from underneath the car, looking for rust perforation or cracks in the chassis rails around the mounting brackets. Use a torch to examine the junction between the subframe and main chassis. Check for rust staining or flaking paint around the mounting area...

  2. Wheel bearing failure

    Wear item 944

    The 944 uses hub-mounted wheel bearings that show premature wear compared to the general fleet. MOT data shows this model fails wheel bearing tests at 136.8x the national average, affecting all engine variants across multiple mileage bands. The combination of the car's weight distribution, suspension geometry, and bearing design creates higher loads than typical passenger cars. Both front and rear bearings are affected, with rear bearings being particularly expensive due to the transaxle design.

    What to check: Jack up each corner of the car and grasp the wheel at 12 and 6 o'clock, then push and pull to check for vertical movement. Any play indicates bearing wear. Grasp the wheel at 3 and 9 o'clock and check for horizontal movement - this may indicate bearing or suspension arm wear. Spin each wheel by h...

  3. Brake system corrosion and binding

    Safety and MOT risk 944

    The 944 brake system suffers from multiple corrosion-related failures at rates far exceeding the national average. MOT data shows brake binding at 55.1x fleet average, brake pipe corrosion at 12x average, and brake hose ferrule corrosion at 13.6x average. The brake lines run through areas prone to salt retention, and the original brake hoses use crimped ferrules that corrode and fail. Brake calipers also seize due to corrosion of the sliding pins and dust seal deterioration.

    What to check: Check brake fluid colour in the reservoir - dark or contaminated fluid indicates system neglect. Inspect visible brake lines under the bonnet and along the chassis for rust, corrosion, or wetness indicating leaks. Look at the brake hose ferrules (crimped connections) for green corrosion or swelli...

  4. Universal joint failure

    Wear item 944

    The 944's rear-mounted transaxle design uses driveshafts with universal joints and flexible couplings to transmit power from the front-mounted engine. MOT data shows universal joint failures at an extraordinary 826.5x the fleet average, affecting all mileage bands. The driveshaft runs the full length of the car in a torque tube, and the rubber flexible coupling (commonly called the 'guibo') deteriorates with age and mileage, causing vibration and eventual failure. Universal joint wear is accelerated by the coupling deterioration.

    What to check: Inspect the rubber flexible coupling (guibo) at the back of the gearbox for cracks, chunks missing, or oil contamination that causes swelling. This is visible from above in the engine bay. Check for any obvious grease leakage around the driveshaft universal joints underneath the car. Look for pla...

  5. Emissions system deterioration

    Wear item 944

    The 944's emissions control system, particularly the catalytic converter and lambda sensor, deteriorates at This primarily affects higher-mileage examples and is exacerbated by irregular servicing and fuel quality issues. The original catalytic converters have limited lifespan and the lambda sensors fail causing rich running and emissions test failures. Cars from this era often struggle to meet modern MOT emissions standards without system updates.

    What to check: Ask to see recent MOT certificates and check the emissions readings - high CO or HC levels indicate system deterioration. Check if the lambda sensor has been replaced recently - it should be done every 60,000 miles on these engines. Look for any aftermarket exhaust modifications that might affect...

What the check includes

944 questions

What are the main problems with a Porsche 944?

The most serious known issues are subframe mounting point corrosion, wheel bearing failure, brake system corrosion and binding. Our car check flags whether a specific 944 has been written off or had insurance claims linked to these faults.

How do I check if a Porsche 944 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 Porsche 944 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 944 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 Porsche 944 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 Porsche 944 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 944 faults that HPI doesn’t include. At £7.49 it’s typically less than half the price of an HPI check.
