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.”

“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.”

“The contact owns a 2014 Infiniti QX80. The contact stated that while driving 55-60 MPH, the service engine light illuminated. The vehicle was taken to a non-Infiniti dealer, where it was diagnosed that the high-pressure fuel pump had failed. The vehicle was repaired. The contact stated that the failure persisted. Most recently, the vehicle was vibrating abnormally. The vehicle was taken back to the non-Infinity dealer, where it was diagnosed that the bucket light cylinder near the camshaft had failed. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 14V683000 (Fuel System, Gasoline); however, the VIN was not included. The manufacturer was not notified of the failure. The failure recurred, and the contact parked the vehicle. The vehicle was no longer driven due to a safety concern. The failure mileage was unknown.”

“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.”

“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!”
