Intermittently the brake lights staying lit after vehicle is turned off and key is removed. Likely that this failure also caused the brake lights to remain lit while driving, rendering the signal ineffective. Lights actually stayed on two occasions causing a dead battery once. Lights were noticed the second time, and wiggling the brake pedal extinguished all three indicators. Dealer replaced the brake light switch under warranty.
