The dealership sold me a car with a rusted subframe without disclosing the condition of the subframe. The car will not pass inspection because of the subframe. I have had two independent inspection stations tell me this car is unsafe to drive. When I contacted the dealership about this, they said it was my problem, not theirs.Owner report · Suspension · Dec 2024

I am the original owner of this 2009 G37 sedan with only 12K miles. This car has never been in an accident. It is perfectly maintained and sits in a garage 99% of the time. Last week the airbag light flashed on. The dealer said the error code was B1018 (Occupant Classification Sensor malfunction). The cost of the passenger seat cushion alone is $7,500. This problem was also found on the 2007 & 2008 G37 models and part of a NHTSA recall (#08V521000). I found this problem all over the internet and this NHTSA site for this model year G37. PLEASE INVESTIGATE THIS PROBLEM. Why isn't this part of the 2007/2008 recall when the sensor is bad in both instances?Owner report · Seats · Dec 2023
Car is parked in open space. Rain occurs throughout the morning and rain water is in the passenger front floor dripping from the A Pillar.Owner report · Structure · Sep 2023
The passenger airbag does not work. The light on the dashboard indicated it needed service. When I took it into the dealer, they said it was $7,000 to fix. (More than the car is worth for resale.) After some research, I've come across complaints about this on multiple sites & comment boards. This is a serious safety issue. I can no longer have passengers in my car (such as my children). Something has to be done.Owner report · Air Bags · Jun 2023
At only 35,500 miles on my 2009 G37 the Passenger Safety Air Bag sensor light continues to blink. Forums are filled with same 2009 passenger safety air bag sensor problems. Infiniti will not cover. Suggested repair is $6,050.00Owner report · Air Bags · Jun 2023
When it rains heavy water gets inside the car on both the drivers side and passengers side leaving the floor extremely wet. It is getting the wires wet. Many infiniti owners are experiencing the same thing and believe inifiniti needs to make a recall.Owner report · Unknown Or Other · Oct 2022
The contact owns a 2009 Infiniti G37. The contact stated that the sunroof drain was clogged, allowing water to enter the vehicle causing electrical system failure. The dealer was made aware of the failure; however, the vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA. The failure mileage was approximately 125,000.Owner report · Visibility · Jul 2022
Car got a flashing airbag light after battery replacement. Reset multiple times just for light to come back. Took to Mears Nissan dealership for diagnosis. Diagnosed with bad occupant detection sensor. Dealership quoted me $4,500 for part without labor. Perfectly good car no longer has operating airbags, my personal safety is now at risk because the cost of repair is greater than the cars value, and the part is on back order for an extended unknown period of time. Vehicle is available for inspection. No other lights at time of incident.Owner report · Air Bags · Jan 2022
