Porsche Taycan Problems: Common Issues and Repair Costs
The Porsche Taycan is one of the most advanced electric vehicles on the road. With its lightning-fast performance, sleek design and luxury features, it’s a strong alternative to Tesla and other premium EVs. But as with any first-generation car, some common faults have emerged. In this guide, we break down the most reported Porsche Taycan problems and what they cost to fix in the UK.
1. Charging and Software Problems
Charging Failures
Owners have reported issues with charging interruptions at both home wallboxes and public rapid chargers. These problems are usually due to software communication errors or charging port malfunctions.
Typical costs:
- Dealer software reset: Free
- Replacement charging port: £400 to £800
- Faulty charging controller: £900 to £1,200
Software Update Glitches
Over-the-air updates sometimes cause problems such as frozen screens, Bluetooth disconnects or inaccurate range readings.
- Dealer reflash or reset: £150 to £350 if out of warranty
- Often covered free under software support
2. 12V Battery Failures
The Taycan uses a standard 12V battery alongside its high-voltage system. If the car sits idle, this battery may drain, leaving the car unresponsive or locked.
Symptoms: Dead screens, doors won’t open, no power.
Replacement cost: £250 to £400
Fitting at dealer: Additional £100 to £150
3. Infotainment System Issues
The Taycan’s large touchscreen interface looks great but has its flaws. Known problems include:
- Frozen or unresponsive displays
- Rebooting during use
- Reversing camera not activating
Fix costs:
- Software update: Free to £250
- PCM unit replacement: £1,500 to £2,200 if not under warranty
4. Suspension and Ride Faults
Air Suspension Sensor Failure
The adaptive air suspension may show incorrect ride height, self-level unevenly or trigger warning messages.
Repair cost: £700 to £1,200 per corner
Rear-Axle Steering Faults
Models with rear-wheel steering can suffer calibration errors or sensor failures, leading to steering system warnings.
Repair cost: £400 to £1,000
5. Electrical Errors and Warning Lights
The Taycan uses dozens of onboard control modules. Occasionally these systems trigger false errors or enter limp mode.
Common warnings:
- Drive system fault
- Chassis error
- “System fault, drive carefully”
Fixes:
- Software reset: £150 to £300
- Module replacement: £1,000 to £2,500 depending on the part
6. Heating and Air Conditioning Faults
The Taycan uses a heat pump to manage both cabin and battery temperature. This system can fail, especially in cold weather.
Common problems:
- Blower doesn’t respond
- Poor cabin heating
- Climate control screen freezes
Repair costs:
- Software fix: £150 to £300
- Heat pump or AC compressor replacement: £800 to £1,400
7. Inverter and Drive Unit Issues
Though rare, some Taycans experience sudden power loss or jerky acceleration. This may point to inverter failure or high-voltage communication problems.
Repair costs:
- Inverter replacement: £2,000 to £4,000
- High-voltage labour (specialist): £500 to £800
Note: Covered under Porsche’s 8-year EV system warranty
8. Braking System Feedback
Some drivers have complained about uneven brake pedal feel, often during the switch from regenerative braking to mechanical braking.
Wear-related repairs:
- Brake pads and sensors: £400 to £800 per axle
- Brake fluid change: £150 to £200

Final Thoughts
The Porsche Taycan is one of the most exciting EVs you can own, but like any premium performance car, it comes with some complexity. Most problems are software or electronic-related and can often be fixed under warranty. But once out of warranty, costs can rise quickly—especially for modules, drive units or climate systems.
