Why won't my Porsche Taycan charge, or keep showing a charging error?

Short answer: Charging errors on a Taycan usually come from the Porsche 240V mobile charger (covered by recall 23V841000), a failing onboard charger, or trouble after recall work. Try a different charger, check your VIN for the cable recall, and if both home and DC charging fail, ask the dealer to test the onboard charger under warranty.

Symptom: The car shows a charging error, home charging won't start or stops overnight, you have to replug many times, or charging is slower than normal.

What to check first

1. Run your VIN at nhtsa.gov/recalls for 23V841000 and ask whether your mobile charger cable was replaced.
2. Try a different charger or a public station to see if it follows the car or the charger.
3. Try both charge ports.
4. If DC fast charging fails too, suspect the onboard charger.
5. Record a video of the error to show the dealer.

Likely causes

1. Recalled or faulty 240V mobile charger. Recall 23V841000 replaces Porsche's 220V/240V portable charging cable because some home outlets can't handle the current at the 100% setting. Owners with charging errors at home often had trouble with this cable.
2. Failing onboard charger (OBC). The onboard charger converts household AC power into DC for the battery. Owners said when it starts to fail, home charging goes first, then DC fast charging can stop too.
3. After recall or software work. One 2021 owner started getting power supply warnings and slow, inconsistent home charging right after the battery recall work.
4. Home wiring or wall charger. Several owners fixed constant errors by switching from the Porsche mobile charger to a wall charger.

What it usually costs

Recall and warranty work is free. One owner was asked to pay about $500 for diagnosis after recall work. Owners bought wall chargers for about $130-$300.

Is it safe to keep driving?

Yes, it's safe to drive, but watch your range. Stop using a charging cable or outlet that gets hot.

DIY or shop?

Trying another charger and checking the outlet is DIY. Onboard charger replacement is a dealer job.

Recalls, bulletins and complaints in plain words

• Recalls: NHTSA lists 23V841000 (various Porsche models including the 2021-2024 Taycan: at the 100% setting on the 220V/240V plug, some home outlets can overheat; dealers supply a new portable charging cable with a temperature sensor) and several high-voltage battery recalls (23V840000, 24V215000, 24V731000, 24V732000). If your car is part of a recall, the dealer fixes it for free.

What owners report

• In Periodic issues with charging on Reddit r/Taycan, an owner got a charging error on both charge ports, at home and at stations. Another 2022 owner's home charging failed first, then DC charging too, and the dealer diagnosed a bad onboard charger with no ETA on the part. Others said it's common when the OBC is failing and should be covered by warranty.
• In Charging issue on Reddit r/Taycan, a 2024 Taycan owner had to unplug and replug 4-5 times to start each home charge. Replies said Porsche's mobile charger has given many owners trouble, and the dealer's suggested fix was to charge at half power. One owner still had errors after both cables were replaced, and several said a separate wall charger fixed it for good.
• In Post-recall charging issues on 2021 Taycan — dealer wants me to pay $500. Advice? on Reddit r/Taycan, a 2021 owner started getting power supply warnings and slow or inconsistent home charging right after the battery and charging recall work, using the same 240V outlet that had worked for 5 years. The dealer wanted about $500 to diagnose it.

Quick tip

Swap chargers first. If the car won't charge anywhere, it's likely the onboard charger, and that's a warranty fight worth having.

Vehicle focus: Porsche Taycan (all versions), 2020-2025.

Safety / mechanic note

A hot outlet or cable is a fire risk. An EV's high-voltage system can stay live with the car off. Leave the orange cables, the big battery and the charging hardware to a trained EV technician. Verify with a mechanic.
