## NHTSA's summary

Hyundai has launched a Product Improvement Campaign to perform a knock sensor software update on the subject vehicles. The software update installs a newly developed Knock Sensor Detection System \(KSDS\) that detects vibrations indicating the onset of excessive connecting rod bearing wear in the engine. The KSDS is designed to alert a vehicle driver at an early stage of bearing wear before the occurrence of engine damage. If vibrations caused by bearing wear start to occur, the Malfunction Indicator Lamp \(MIL\) will blink continuously, an audible chime will sound, and the vehicle will be placed in Limp Home Mode. At that time, Diagnostic Trouble Code \(DTC\) P132600, specific to the KSDS, will be recorded in the ECM. The vehicle can continue to be operated for a limited time in Limp Home Mode, but it will accelerate slowly and have a reduced maximum speed with RPMs limited to approximately 1800\-2000 RPM.
