The short version

General Motors LLC reported a problem with the power train automatic transmission. Here is what owners need to know.

WHAT

The start/stop accumulator endcap may have missing bolts.

WHY IT MATTERS

Missing bolts on the start-stop accumulator endcap could result in a transmission oil leak and may progress to a loss of propulsion, increasing the risk of a crash. A transmission fluid leak in the presence of an ignition source may increase the risk of fire.

WHAT TO DO
