What's wrong, in plain English

The pre-collision automatic hazard lights on certain Taycan vehicles may turn on during situations that are not actual emergencies. Because the lights are not being used the way they're meant to be, the vehicle does not meet the federal requirements for this equipment.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your vehicle is included.
2. Contact a Porsche dealer, or call Porsche customer service at 1-800-767-7243 (recall number AMC1).
3. The repair (reprogramming the hazard lights) is free.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 21V794000.
