Example complaints

Air bags: “The red airbag light on the instrument panel IS on. I have taken the car to the infinity dealer and they say a sensor is out and would be $800 to $1000 to repair. It seems the airbag system should be warranted as long as the car is registered. The mfg book says if this light is on the airbag may inflate, not inflate when needed, just not work. I am concerned, I do not want the bag to inflate as I or my wife is driving. …”

NHTSA complaint #11570834, filed 2024-02

Electrical system: “I was driving the vehicle today and the car started to stall. Several lights came on like service, engine light, break light. Then total shutdown. I took it to local mechanic and he suspects that there's a problem with ignition and key tumbler. This sounds a lot like the GM problem with weak key tumblers and causing sudden stall and crash. Please investigate if Infiniti I35 2004 have similar problems and should be recalled.”

NHTSA complaint #10627093, filed 2014-08, 77,000 miles

Engine: “I had the oil changed in june 2013. In early july my daughter said that the engine light came on and a day or two later the car was making loud noises from under the hood. We checked the oil and it was bone dry. We chalked it up to the last oil change as not having enough oil put in it. Well, 5 weeks later the same thing happened along with the oil light. I checked the oil and it's bone dry. All warning lights go off after putting oil in. The car is burning oil, a lot of oil very quickly with no residue on the driveway. …”

Engine cooling: “The I35 was hard to start, tcs, slip and check engine lights stayed on. Dealer diag. Bank 2 cam shaft pos sensor failure. This problem appeared similar to NHTSA 2003 campaign number 03v455000. Dealer stated there were no recalls for this problem in 2004 I35. The 2003 campaign report date was 04 nov 2003. My I35 was manf. 07 oct 2003. I feel my 2004 cam shaft pos sensor should also be included in the 03v455000 or a new recall issued for it. The Infiniti dealer would not cover the cost of replacing the failed cam shaft pos sensor.”
