ELECTRONIC STABILITY CONTROL (ESC)
General Motors LLC (GM) is recalling certain model year 2014 Cadillac ELR vehicles not equipped with adaptive cruise control and manufactured September 26, 2013, through February 14, 2014, and equipped without adaptive cruise control. In these vehicles, the electronic stability control (ESC) system software may inhibit certain ESC diagnostics, preventing the system from alerting the driver that the ESC system is partially or fully disabled. As such, these vehicles fail to conform with Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control Systems."
SEATS
General Motors LLC (GM) is recalling certain model year 2013-2014 Buick Encore and Cadillac ATS; 2014 Cadillac CTS, ELR, Chevrolet Caprice and SS vehicles; and 2014-2015 Chevrolet Silverado and GMC Sierra Trucks. Due to an incomplete weld on the seat hook bracket assembly, the front seats in the affected vehicles may not stay secured in place during a high load condition such as a crash.
