Example complaints

Fuel system: “I apologize in advance if I’m not using the correct form to find out this information, hopefully if this does not reach correct person you can get to correct person for me. There has been a constant gas smell coming from gas tank area since we purchased vehicle in 2/2026. I thought it was just fumes from adding fuel but have since (while reaching in to retrieve grandbaby from back seat, I noticed a strong smell reaching towards driver door and a slight gas smell reaching inside vehicle. We have not been able to locate a gas leak anywhere just the strong gas smell. …”

NHTSA complaint #11759908, filed 2026-08

Engine: “I starting hearing a grinding noise coming from engine couple of weeks ago. Took it to the Infinity dealership for a diagnostic test. The mechanic stated “ timing chains were found to be stretched and metal was worn.” This is the same issue which prompted the recall of 2011-2013 QX56 models. However, I did not own my vehicle during the recall period.”

NHTSA complaint #11500607, filed 2023-01

Electrical system: “Ignition randomly will not start. Mechanics can not locate the issue only stating that it is traced back to an unknown electrical problem. I've heard about this same issue from other fellow QX80 owners. Again this is random and can happen for days at a time and then not at all for a week and then resurface. My family and I have been stranded in inclement weather, dangerous areas of unknown cities with this problem and it needs to be fixed! This has occurred 7 times in the past 2 days.”
