March 13, 2019 — General Motors power steering problems have caused a recall of nearly 27,000 model year 2016-2018 Cadillac CTS, 2017 Cadillac ATS, 2017 Chevrolet Camaro and 2017 Chevrolet Corvette vehicles.

The electric power steering may fail while driving and cause the vehicles to revert to manual steering, making turning the steering wheels much more of a chore.
A loss of power steering while driving slow speeds or around curves can easily cause a crash.

GM opened an investigation in September 2018 into sudden power steering losses in 2017 Chevrolet Camaros based on information from the National Highway Traffic Safety Administration.

Engineers determined intermittent electrical problems occurred in the torque sensor printed circuit boards of the power steering gear assemblies in about 80 percent of the cases.
The gear assemblies were supplied by Bosch, and additional investigations also found the same problems in two Chevy Corvette steering gear assemblies.

By analyzing the data GM found the same circuit boards were installed in Cadillac ATS and CTS vehicles.
This was followed by spikes in warranty rates that were traced to manufacturing errors made by the power steering supplier.

The automaker says a loss of power steering can last the entire time the vehicle is running, but it's possible power steering while return once the vehicle is restarted.
A driver should see a message and hear a chime within a few seconds of losing electric power steering.

The recall starts in March 2019 when GM dealerships will replace the power steering gear assemblies.

Affected customers may call the automaker at 800-222-1020 and refer to recall number N182182760.

Complaints about the Cadillac CTS, Cadillac ATS, Chevrolet Camaro and Chevrolet Corvette.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-3Four General Motors models – including Corvette – are being recalled because of potential electric power steering failures.

Included in the recall are about 27,000 vehicles, including the 2017 Corvette, 2017 Chevrolet Camaro, 2017 Cadillac ATS, and 2016-18 Cadillac CTS.
GM discovered the problem after opening an investigation last September into sudden power steering losses in 2017 Camaros based on information from the National Highway Traffic Safety Administration.
The failures may occur while driving, making it difficult to turn the steering wheel.
That could make it especially dangerous at slow speeds or around curves.
GM engineers determined that in about 80 percent of the cases involving Camaros, intermittent electrical problems occurred in the torque sensor printed circuit boards of the power steering gear assemblies.
Further investigation discovered the same problems in two Corvette steering gear assemblies, and GM also found the same circuit boards being used in the two Cadillac models.
GM also noticed a spike in warranty repairs that were traced back to manufacturing errors made by Bosch, which supplied the power steering assemblies.

The failure will apparently last the whole time the car is being driven, but the steering sometimes returns once the vehicle is turned off and restarted.

Drivers are alerted to the failure by the difficult steering, obviously, as well as an instrument panel message and the sounding of a chime.

GM dealers will replace the power steering gear assemblies starting this month.
