NHTSA recall 15V011000

What's wrong: Affects vehicles equipped with an accessory trailer light module. The software within the module may incorrectly detect an electrical short and preventively turn off the electrical current and the trailer lights.

Why it matters: If the system incorrectly detects an electrical short and turns off the trailer lights while the trailer is being towed at night, there is an increased risk of a crash.

The fix: Set will notify owners, and dealers will replace the trailer light module with a new unit with corrected software, free of charge. The recall began on March 17, 2015.
