Infiniti G37 Problems
A "tapping sound" may develop from the drivers side of the engine. The noise may be associated with the variable valve event and lift actuator. Our technicians tell us a software update for the powertrain control module (PCM) is available to correct this issue.
Vehicles with a 7 speed automatic transmission may experience a harsh downshift from 4th to 3rd gear on deceleration. Our technicians tell us revised control module software is available to correct this concern. On higher mileage vehicles other faults may cause transmission shifting issues. Whenever a transmission repair is performed, the control module should be checked for the latest software and updated if necessary.

Infiniti G37 Recalls
The power window switches were incorrectly manufactured. The auto-reverse feature does not operate and a pinch injury may result before the window reverses direction. Dealers will replace the power window switches to correct this concern.
This recall affects certain vehicles equipped Occupant Classification System (OCS) control units manufactured by Continental Automotive Systems. A varistor in the OCS control unit may have been manufactured out of specification. Under certain conditions, this could interupt the signal between the OCS and the air bag control unit (ACU), causing the passenger air bag to be suppressed in an accident. If the air bag does not deploy when needed in a crash, the risk of injury is increased. Dealers will test the signal between the OCS and ACU with a special tool to verify proper function. The seat cushion containing the OCS hardware will be replaced as necessary. The recall began November 4, 2008.
Infiniti G37 Reviews
twice within the last 3 weeks, the brakes on the car did not hold. First time was lucky. Infinity promised that they took the brakes apart, and checked them thoroughly. Just had a minor accident near my home because again the brakes did not hold. The car jerked forward twice with my foot on the brake pedal, unable to stop it. Has anyone else ever had this problem?
Great car. comfortable, everything works easily and as expected. This is my second G35/37 and if they keep improving it I'll buy a third, that is if they keep the V-6 and improve the HP and torque.
I love my G37S. The driving experience is wonderful. It's not quite as luxurious as the Lexus IS series on the inside, but it's real close. And what it lacks there it more than makes up for in sportiness.
