Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My audio and climate control system have completely stopped working. I have no control of the rear or front defroster which is a serious safety hazard. Infiniti issued a recall for the problem however my car wasn't covered even though it is the exact same problem.”

NHTSA complaint #10463289, filed 2012-06, 90,000 miles

“2003 Infiniti G35. The radio, A/C, & heat controls go out due to a terrible mistake by the engineers in routing the radio and climate controls to one circuit board. Living in the mid-west this is a huge issue because I cannot defrost my windows when it's snowing. Infiniti issued a voluntary recall, but most likely missed around 90,000 cars. This is a large problem and they do nothing, it's a huge safety risk.”

NHTSA complaint #10370669, filed 2010-12, 110,000 miles

“Radio/AC went out and are malfunctioning. I started my car and when turning on the radio the AC went to auto AC and went up to level 5 with out any warning. My radio followed by not working. All lights on the radio AC console went out and I am unable to control either from steering wheel or console. The audio finisher circuit board will have to be replaced. Over 1700 complaints found related to this topic with 2003 G35 Infiniti's.”

NHTSA complaint #10287033, filed 2009-10, 113,000 miles

“I have a 2003 Infiniti G35. The center console, controlling the heater/AC and the radio is not working. I was told that there is a control board problem that Infiniti is not claiming, yet according to the web, there are several complaining of the same problem.”

NHTSA complaint #10292702, filed 2009-11, 322,800 miles

“Per G35 sedan recall my '...audio and temperature controls may, on occasion, not operate as expected.... . My equipment failed multiple times. There is a voluntary recall for this problem on the G35 sedan but not the G35 coupe. The mfg'r. States that coupe is not covered even though I have the same problem. My G35 has/had the identical problem and they replaced my circuit board at a cost of $649.88 (parts and labor). I believe the G35 coupe should have same recall as the G35 sedan.”
