On the 2020-2025 Porsche Taycan, the Taycan 12V auxiliary battery drains excessively when the vehicle is parked, even for short periods. The numerous electronic modules and always-on connectivity features draw more current than the 12V battery management system can sustain. A dead 12V battery prevents the car from powering on even with a full high-voltage battery.

This issue also affects: Audi Q8 e-tron, Porsche Panamera

Common Symptoms

Vehicle will not power on despite full main battery
12V battery warning on dashboard
Keyless entry not responding
Dashboard going blank after short parking period
Need to jump-start 12V system

How to Fix

Update to the latest Porsche software version which includes improved 12V battery management. Replace the 12V battery with an AGM unit if degraded. Install a 12V battery maintainer for extended parking. Disable unnecessary always-on features in the vehicle settings.

On the 2020-2024 Porsche Taycan, a supplier manufacturing defect in certain LG-built lithium-ion battery modules (assembled in Poland) can cause internal damage that develops into a short circuit within the high-voltage pack. There is no early warning to the driver, and in the worst case the short can trigger a thermal event or fire. This is a safety/fire-risk defect separate from the gradual capacity/range loss owners also report. Porsche issued an interim instruction to limit charging to 80 percent state of charge until the fix was available.

Common Symptoms

No early warning before failure
Battery-related warning messages
Charging limited to 80% per Porsche advisory
Potential thermal event or fire in rare cases

How to Fix

Recall remedy (NHTSA 24V-732 / Porsche ARB6/ARB7, which superseded earlier campaigns 23V-840, 24V-215, 24V-217): dealers install advanced battery-monitoring diagnostic software that continuously watches for patterns of internal damage, and replace individually affected cell modules — or the entire pack where flagged — free of charge. Owners were told to charge only to 80% until the diagnostic software/repair was applied.

On the 2020-2025 Porsche Taycan, the Taycan occasionally fails to initiate or complete DC fast charging sessions. Issues include charge port communication errors, reduced charging speeds below the advertised 270 kW peak, and charging sessions terminating prematurely. Software compatibility between the vehicle and various charger networks is the primary cause.

Common Symptoms

Charge session failing to start
Charging speed much lower than expected
Charging session stopping prematurely
Error message on charger screen
Charge port light flashing red

How to Fix

Update vehicle software to the latest version. Try a different charger or charging network if one consistently fails. Pre-condition the battery (use the navigation to route to a charger) before DC fast charging to achieve maximum charging speed. Report charger-specific failures to both Porsche and the charging network.

On the 2020-2025 Porsche Taycan, some Taycan owners report faster-than-expected range degradation, particularly in cold climates and after frequent DC fast charging. The battery management system may also display inconsistent range estimates. While some degradation is normal for lithium-ion batteries, rates exceeding 5% per year are considered above normal.

Common Symptoms

Noticeable range reduction compared to when new
Estimated range lower than expected for charge level
Range dropping faster in cold weather
Battery capacity showing degradation in diagnostics
Inconsistent range estimates between drives

How to Fix

Have the battery health checked at a Porsche dealer using PIWIS diagnostics. Minimize DC fast charging to 80% and prefer AC home charging. Avoid storing the vehicle at very high or very low states of charge. Porsche provides an 8-year/100,000-mile battery warranty covering capacity loss below 70%.

On the 2020-2025 Porsche Taycan, transient signal noise between the control unit and the Surround View cameras can, in rare instances, interrupt the rearview camera's ability to display an image when the car is shifted into reverse. A blank or failed backup camera image when reversing reduces rear visibility and violates federal rear-visibility requirements, increasing the risk of a backover collision.

Common Symptoms

Blank/black rearview camera screen in reverse
Camera image fails to appear when shifting to reverse
Intermittent loss of backup camera feed

How to Fix

Recall remedy (Porsche campaign ASB2): dealers install a free software update that makes the camera system more resistant to signal noise and better at recovering a lost signal if the feed is interrupted. As an interim measure owners should rely on mirrors and direct visibility when backing up.

On the 2020-2024 Porsche Taycan, the electrically actuated charge port doors (power supply flaps) commonly fail to open or close, or get stuck halfway, preventing charging. Because the Taycan uses a 'cross-lock' safety function that locks the opposite flap whenever one is opened, a fault on one side can produce a misleading error message for the other side, making diagnosis confusing. Owners report this across model years from 2020 onward; failures are typically the flap actuator motor, wiring, or module.

Common Symptoms

Charge port door won't open or close
Flap stuck halfway
Error message references the wrong (opposite) side due to cross-lock
Unable to charge

How to Fix

Porsche addressed it via TSB 186/24 and workshop campaign WLK2 (covered by a later TSB dated April 7, 2025): dealers replace the failed actuator, repair wiring, or replace the entire flap module as needed. As a temporary workaround, lock the car, move the key fob at least ~30 feet away, and wait 15-20 minutes to let the systems reset, which can restore flap function. Out-of-warranty actuator/module replacement typically runs a few hundred dollars in parts plus labor.

On the 2020-2024 Porsche Taycan, the optional 22 kW onboard AC charger (OBC) is prone to failure. When it fails the car throws a yellow 'Electrical System Fault' warning and, in some cases, the car will not move at all; AC (Level 2) charging stops working. Porsche reportedly cannot reliably supply replacement 22 kW units and has discontinued the option, so it offers owners compensation (~€1,700-€1,800) to downgrade to the more reliable 11 kW charger. Out-of-warranty replacement of the original unit is very expensive.

Common Symptoms

Yellow 'Electrical System Fault' warning
AC / Level 2 charging fails
Car will not move in some cases (yellow screen)
Reduced or no onboard charging capability

How to Fix

Under warranty (including Porsche Approved Warranty), the OBC is replaced as a warranty claim. Because 22 kW units are scarce, Porsche commonly offers a goodwill payment (~€1,700) to downgrade to the stable 11 kW charger, which dealers note rarely fails. Out of warranty, a replacement can run roughly $7,000-$10,000 depending on dealer, making the 11 kW downgrade the practical fix.

Typical repair cost:$1,800 - $10,000

On the 2021 Porsche Taycan, an incorrectly machined groove in the support-bearing area of the air spring strut can cause the retaining ring to seat improperly. The ring can come loose, allowing the strut to become dislodged and air to escape from the air spring. The vehicle then drops on one corner, an air-suspension warning appears, and handling/control can be compromised. Documented on air-suspension-equipped early Taycans (and the sister Audi e-tron GT) via a US recall; German owners have reported similar low-volume cases on motor-talk.de.

Common Symptoms

Vehicle lowers/sags on one corner
Air suspension warning message in instrument cluster
Audible air leak from a strut
Degraded ride height and handling

How to Fix

Recall/repair remedy: dealers inspect and replace the affected air spring strut(s) where the retaining-ring groove is out of spec, free of charge under the campaign. Owners noticing the car sitting low on one corner with a suspension warning should stop driving and have it inspected before further use.

On the 2020-2025 Porsche Taycan, the Taycan front suspension produces clunking and creaking noises over bumps and during low-speed maneuvering. The issue is traced to the upper strut mounts, control arm bushings, and anti-roll bar end links. The heavy battery pack places additional stress on the front suspension components, accelerating wear.

Common Symptoms

Clunking over bumps
Creaking during low-speed turns
Rattling from front suspension area
Noise worse in cold weather
Steering wheel vibration over rough surfaces

How to Fix

Replace worn upper strut mounts, control arm bushings, or anti-roll bar end links. Porsche has released updated parts with improved durability. Lubricate suspension contact points with silicone-based lubricant as a temporary measure.

On the 2020-2025 Porsche Taycan, the front brake hoses can become over-stressed at their point of minimum bending radius during certain steering and driving conditions, damaging the inner fabric liner. Over time the hose can crack and leak brake fluid, dropping hydraulic pressure at the front axle, extending stopping distances and degrading braking in extreme cases. Production cars built after May 13, 2024 received revised hoses with a larger bending radius.

Common Symptoms

'Brake fluid low' warning
'PSM failure' message
Longer stopping distances
Spongy or reduced braking
Brake fluid leak at front axle

How to Fix

Recall remedy (NHTSA 24V-455 / Porsche ARB0): dealers replace the front brake hoses with revised hoses that have an increased bending radius, free of charge. Owners seeing 'brake fluid low' or 'PSM failure' messages should stop driving and have the vehicle inspected.

On the 2022-2023 Porsche Taycan, a manufacturing defect in the crimp connection of the front passenger seat cushion's heating mat can cause the Occupant Classification System (OCS) to malfunction and enter a fail-safe mode, deactivating the front passenger airbag even when the seat is occupied. In a crash the passenger airbag may not deploy. Affected cars were built between Jan 3, 2022 and Mar 31, 2023; the faulty cushion was supplied by Lear Corporation Hungary.

Common Symptoms

'Passenger Airbag OFF' warning light stays on with an occupant seated
Airbag warning chime
Dashboard airbag error message

How to Fix

Recall remedy (NHTSA 25V-221): dealers replace the entire front passenger seat cushion with an updated version featuring a more robust crimp connection, free of charge. Owners who see the 'Passenger Airbag OFF' light illuminated with an occupant in the seat should treat it as the defect symptom and get it inspected.

On the 2020-2021 Porsche Taycan, a software fault in the pulse-control inverter / power electronics and motor control unit can incorrectly detect a fault and trigger a complete shutdown of the powertrain while the car is in motion. The driver gets a warning such as 'Motor control error - Stop vehicle in a safe place' and the car coasts to a stop with no drive power; steering and brakes remain. This is a high crash risk in highway or passing situations. Affected roughly 43,000 cars globally.

Common Symptoms

Warning 'Motor control error - Stop vehicle in a safe place'
Sudden complete loss of motive power
Car coasts to a stop
Acceleration lost while steering and brakes remain

How to Fix

Recall remedy (NHTSA 21V-486 / Porsche campaign AMB5): dealers reprogram the power electronics / motor control software so a false error message no longer triggers a full powertrain shutdown. The update is free and takes about an hour in the workshop.
