GM warns some Bolt owners to park outdoors due to fire risk

DETROIT (AP) — General Motors is telling owners of some older Chevrolet Bolts to park them outdoors and not to charge them overnight because two of the electric cars caught fire after recall repairs were made.

The company said Wednesday that the request covers 2017 through 2019 Bolts that were part of a group that was recalled earlier due to fires in the batteries.

Kelly said owners who haven't had the recall repairs done should still take their cars to dealers to get the fixes.

GM traced the fires to what it called a rare manufacturing defect in battery modules. It can cause a short in a cell, which can trigger a fire. Under the remedy, dealers were to install software designed to warn owners of problems, and any defective cells were to be...
