Subaru is recalling certain 2018 Subaru Legacy and Outback vehicles. Due to a software error, the low fuel warning light may not illuminate at the intended remaining fuel level and the miles-to-empty display may incorrectly indicate a positive number despite the tank being empty. The inaccurate fuel display may cause a driver to unexpectedly run out of fuel and the vehicle to stall, increasing the risk of a crash.

What's the problem?

The recall affects approximately 228,648 vehicles. Subaru began investigating reports in December 2017 of positive miles-to-empty displaying despite no available fuel. Through collaboration with its suppliers, Subaru determined the problem was related to a software error that fails to properly detect and warn of a low fuel condition.

The problem was corrected in all vehicles for the 2019 model year.

What happens next?

Subaru will notify owners, and dealers will reprogram the combination meter software free of charge. The manufacturer has not yet provided a notification schedule as the tools needed to perform the procedure are not yet available.

Owners may contact Subaru customer service at (844) 373-6614. Subaru's number for this recall is WTW-82.
