One problem related to power steering pump has been reported for the 2012 Infiniti G37. The most recently reported issues are listed below.
Power steering pump and passenger airbag malfunction. Many Infiniti owner have or have had the same issue. I think customers don't have to pay for any repairs if there is a big demand on these problems. These two problems happen when my family and I were driving on the highway. I don't understand why this problem hasn't been called as a recall.
