General Motors (GM) is recalling certain 2016-2018 Cadillac CTS, 2017 Cadillac ATS, 2017 Chevrolet Camaro, and 2017 Chevrolet Corvette vehicles. The electric power steering (EPS) assist system may fail while driving. If power steering assist is lost, manual steering functionality is retained but would require increased steering effort, particularly at lower speeds, increasing the risk of a crash.

What's the problem?

These vehicles may experience a loss of EPS assist while driving. Loss of EPS assist may last an entire ignition cycle, but may return once the vehicle is restarted. Customers may experience this condition during subsequent ignition cycles. A manufacturing error at the power steering supplier affected electrical connectivity on the printed circuit board within the steering gear assembly. The connectivity issues could result in intermittent open circuits and a loss of EPS assist.

If power steering assist is lost, manual steering functionality is retained but would require increased steering effort, particularly at lower speeds, increasing the risk of a crash.

If power steering assist is lost (i.e., the vehicle reverts to manual steer) a driver information center (DIC) message and audible chime will occur within a few seconds of the intermittent condition and may alert the driver of an EPS problem.

What happens next?

GM will notify owners and dealers will replace the power steering gear assembly free of charge.

Interim letters informing owners of the safety risk are expected to be mailed in late March 2019. Owners will receive a second notice when the remedy becomes available.

GM's number for this recall is N182182760.
