The Porsche Taycan is a high-performance electric vehicle that has garnered attention for its impressive technology and driving experience. The most common failures include tyre wear, suspension problems, and electrical faults, with repair costs varying based on the specific issue.

Tyre Wear and Damage

Tyres are a critical component of any vehicle, and the Porsche Taycan is no exception. Common MOT failures related to tyres include insufficient tread depth and damage from road hazards. The legal minimum tread depth in the UK is 1.6mm, and anything below this can lead to an MOT failure.

Replacing tyres on a Taycan can be expensive due to the high-performance nature of the vehicle. Regular checks and rotations can help extend the life of the tyres, reducing the likelihood of MOT failures.

Suspension Issues

The suspension system of the Porsche Taycan is designed for optimal performance and comfort. However, common issues such as worn shock absorbers or damaged bushings can lead to MOT failures. These problems often manifest as excessive noise or poor handling.

Regular inspections can help catch issues early, potentially saving on more extensive repairs down the line.

Electrical Faults

As an electric vehicle, the Taycan relies heavily on its electrical systems. Common MOT failures can arise from issues with lights, indicators, and battery management systems. Faulty bulbs or wiring problems can lead to immediate failures during testing.

Keeping the vehicle’s software updated and regularly checking all electrical components can help prevent these issues.

Brake System Concerns

The brake system is vital for safety, and any issues can lead to MOT failures. Common problems include worn brake pads, damaged discs, or fluid leaks. The Taycan’s advanced braking system requires regular maintenance to ensure optimal performance.

Regular brake inspections and timely replacements can help ensure that the vehicle passes its MOT without issues.

Windscreen and Wiper Failures

The windscreen and wiper system are often overlooked but are crucial for visibility. Common MOT failures include cracks in the windscreen or worn wiper blades. Any damage that impairs the driver’s view can lead to an immediate failure.

Regular checks can help maintain visibility and prevent MOT failures.

Exhaust and Emission Issues

While the Taycan is an electric vehicle and does not have a traditional exhaust system, it is essential to ensure that any auxiliary systems are functioning correctly. Issues with the battery cooling system or other components can lead to MOT failures related to emissions.

Regular maintenance and checks can help ensure that all systems are functioning optimally, reducing the risk of MOT failures.

Porsche Taycan recall record

17 recalls have been issued for the Porsche Taycan, between 2021 and 2026.

  1. ASB1 Recall campaign - Check wiring harness of the front seats and rework if necessary

    R/2026/015

    Issued 16 January 2026

    For affected vehicles there is a possibility that the wiring harness for the front seats has not been installed in accordance with specifications and the harness may be damaged by seat adjustment over the lifetime of the vehicle.

    Remedy:To prevent this the installation of the affected wiring harness is to be checked and if necessary reworked.

    Affects cars built Apr 2024 to Dec 2025

  2. ASA6 - Check the air suspension strut on the front axle and rework if necessary

    R/2025/264

    Issued 8 July 2025

    There is a possibility that a locking ring on the air-spring strut at the front left and right was not fitted according to specifications on the affected vehicles. If this is the case the locking ring on the upper side of the respective spring strut can loosen and air can thus escape from the air spring. As a result the driving characteristics may be impaired which increases the risk of an accident.

    Remedy:The locking ring on the air-spring strut at the front left and right must be checked and reworked depending on the test result

    Affects cars built Dec 2024 to May 2025

  3. ARB6 recall campaign – Checking HVB cell modules and re-programming BMCe software

    R/2024/454

    Issued 11 November 2024

    A short circuit within the battery modules during the vehicle’s service life cannot be ruled out under certain circumstances which could lead to thermal events and later to a fire in the vehicle.

    Remedy:On the affected vehicles the battery modules must be replaced and the on-board diagnostic software (BMCe control unit) will be installed.

    Affects cars built Oct 2019 to Mar 2024

  4. ARB5 Recall Campaign - Replacing cell block module on high-voltage battery.

    R/2024/407

    Issued 16 October 2024

    On affected vehicles production issues may have occurred at the battery cell / module supplier. A short circuit within the battery modules leading to thermal events and fires cannot be ruled out.

    Remedy:Replace the affected battery module on the high-volt battery.

    Affects cars built Nov 2019 to Jun 2023
