## NHTSA's summary

If, during winter months, the vehicle is used mainly for short trips, it is possible for an excessive amount of condensed water to collect in the rear muffler. When the condensed water level in the muffler reaches a certain point, it is possible for this water to run into the exhaust pipe and freeze overnight, preventing the engine from starting.
