Filed Aug 27, 2026 · Fuel system · SC

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. I’m trying to find out if this is a common occurrence for this vehicle or if there is a recall on it for this problem. Also if there has been a recall is there a way I can find out if the recall has been repaired. Thanks for any information you can provide.

My daughter was driving this car home from college on I80 east from Iowa to joliet and almost was involved in a accident. The stearing started to lean to the left and when she had to slow down and brake the stearing went hard to her left until she released the brake. she pulled over and called me i came out and drove it home slowly. i took it to my mechanic which i thought it was an alignment issue or a caliper on rear brakes. However it was brought to my attention by the mechanic that the left side of the rear sub frame was rootted out by rust and broke almost causing a major accident. I have been to the Infinity of Naperville three times this year and muliple times over the course of 2yrs for maintence and the rear sub frame passed the inspection everytime! This should be a saftey concern for all of these Infinity QX80 vehicles in illinois that are exposed to salt with this kind of metal for a frame. This product that Infinity manufactured completly broke while driving after being inspected and passed just 3 months ago. I am also conserned about my main frame also. The 1st pic I have icluded is my rotted out sub frame and the 2nd 3rd pic is the rotting main frame!

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.

My airbag indicator light came on almost immediately following purchase. I took it to be fixed by infiniti service department. After picking up the vehicle, the light came back on. This cycle repeated multiple times. The 4th time, infiniti stated they have completed the "flow chart" provided by the manufacturer to solve the problem and had to speak to engineers to troubleshoot next steps. They quoted another part of the airbag system to be replaced. This time, I requested a guaranteed fix. They denied the request and stated they cannot guarantee anything. Client affairs has contributed toward the costs of some of the repairs as good will. At this point, this safety issue should no longer fall on the consumer at all since infiniti cannot seem to fix the issue within a reasonable number of attempts. There is currently a class action lawsuit against takata for faulty airbag systems causing hundreds of injuries and even deaths. There are tons of recalls, yet this vehicle is not on a recall list. My extended warranty, the lemon law, the dealer, and the service department have all denied responsibility of the safety airbags. They are now having me pick the vehicle up, unresolved, despite the risk to my safety. I am moving forward with next steps to file safety complaints and publically express my concerns before someone gets hurt. I want my vehicle to be considered for airbag recall immediately. I will be happy to provide any documentation needed upon request. Thank you for your any investigation into this and consideration for recall.

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.
