Recalls for the 2007 Kia Optima: 2
The clock spring contact assembly for the driver's side air bag supplemental restraint system (SRS) may become damaged through usage over time. If the clock spring develops high resistance, in the event of a crash, the drivers air bag will not deploy and will not be able to properly protect the driver, increasing the risk of injuries.
There is a possibility that the shift cable may have been installed incorrectly, causing tension in the cable. If present, this condition could cause the cable to detach from the shifter assembly's dowel pin preventing the transmission from being shifted. If the driver leaves the vehicle without engaging the parking brake, there is a possibility that the vehicle can roll injure a person in its path or cause a crash.
