Example complaints

“My passenger seat weight sensor is malfunctioning going on and off at various times into the drive and various weighted passengers. This seems to be a very common problem on my 2012 G37 sport and the seat (sensor cannot be changed out so have to buy the whole seat) ranges between $5000 and $8000. This seems to me to be a safety issue, what were to happen if any one of us having this issue were to get into an accident with a passenger? …”
NHTSA complaint #11243986, filed 2019-08, 112,000 miles“Passenger airbag light blinks. Took car to dealer and they said the seat bottom needs replacing as it is an occupancy sensor failure. Cost for part is $6500.00. Cost to install and reset is $500. That repair is half the value of what it is worth. I called infinity'not under warranty or recall. Have read online that multiple owners of these models are having same issue. I feel that this is a potential safety-related defect in the vehicle.”
NHTSA complaint #11165767, filed 2019-01, 85,327 miles“I brought in my 2012 for maintenance at an Infiniti service dealer. I received a new battery as I was told the battery needed replacement soon. Come to find out, the new battery was actually a faulty component and my car would not start. I brought it in for diagnostics and they said nothing was wrong. I told them that it must be the battery since I never had that issue before. The battery issue continued and I would have to jump my car off. …”
NHTSA complaint #11170171, filed 2019-01, 86,000 miles“Infiniti G37 convertible year 2012, with 11,400 miles (secondary car very low miles) displayed passenger airbag error/will not deploy airbag in a crash. The car was started and the display light never went off and has stay on every since while driving. Took the car to westhouston Infiniti service one week later and was told a sensor was bad and that the entire seat would require replacement at a cost of 6k (my seat is almost brand new). I questioned why I should have to pay for what is surly a design flaw and the price is outrageous. …”
NHTSA complaint #11286661, filed 2019-12, 11,387 miles“There is a leak on the driver side down the front A-pillar. Water runs over the electrical components, fuse box, BCM. I’ve researched on the internet and this is an extremely common problem. If this component gets wet, the car could shut off while driving. Maybe there is a danger with being electrocuted as well. This is a design flaw and potential safety issue in the 2012 Infiniti G37, and it’s happening fairly often as seen with similar issues from other owners. Do I have to worry about this with my two kids in the car? …”
