2015 INFINITI QX60 Engine Problems

Shortly after purchasing this used vehicle from CarMax, the vehicle began experiencing serious mechanical failures involving the engine/emissions system, braking system, and suspension. The vehicle displayed a check engine warning light, and the selling dealer, CarMax Schaumburg, confirmed issues requiring repair, including a faulty oxygen sensor, brake-related repairs, and a suspension link. The vehicle was taken in for service, parts were ordered, and repairs were performed. Despite these repairs, the same issues reoccurred, requiring the vehicle to be returned for additional repair attempts. The problems were therefore reproduced after the initial repair, confirming the existence of unresolved defects. The vehicle was not reliably safe during this period. These failures posed safety risks due to reduced braking reliability, compromised vehicle stability, and engine performance concerns, which could affect drivability and safe operation under normal conditions. The defects were confirmed and serviced by the dealer, as documented through service communications and voicemail messages from CarMax. Warning indicators, including the check engine light, were present prior to repair and prompted service visits. Exact mileage at the time of the incidents is UNKNOWN, as it was not clearly disclosed at purchase. Before the issues were fully and permanently resolved, the vehicle was repossessed, resulting in the loss of the vehicle while unresolved safety and mechanical defects existed. The repossession prevented further inspection or repair by the consumer. The repaired components and service records should be available for inspection through the dealer. No police or insurance inspection occurred in connection with a collision, as the issue involved mechanical and safety defects rather than an accident.

I took my 2015 qx60 into the infiniti dealership on 4/3/2023 because it was misfiring, was told that there was a coolant leakage into cylinder 2, I need to get a new motor and was given a 25,671.77 quote. I just had my car at the same dealership on 1/26/2023 and was told that everything was fine with my car. The problem started in March and I just had gotten gas, so I thought it was bad gas and needed to drive it out. But when I finally driven it out and got more from another station the problem persist. During this time my service engine light did not come on, my car did not run hot nor did it smoking and it only has 77k. I am the original owner of this car and could not believe that the lifecycle of this luxury car is only 7 years, so I reached out to infiniti consumer affairs on 4/10/2023 for help to make sure that this is not a manufacturers defect. I was told by the representative that opened a case for me to have my car towed to another dealership for a second opinion which I did on 4/11/2023. My infiniti dealership advisor called me on 4/12/2023 and said that it would be $3000 to do a deep dive into the motor, so I called infiniti consumer affairs back and after the new representative came up to speed on my case, I was told that they would not help me with find the cause of this leakage. My warranty just expired on 12/19/2022 and I feel completely blindsided because when I purchase my brand new infifniti qx60 I thought I was purchasing a reliable car that I would have for longer than the 2004 nissan sentra that I traded in after having it for 11 years.

When tempature is hot outside or if I sit in idle for a while in traffic, car starts skipping, stalling and shuts off. I’ve already taken it to two dealerships to be fixed and spent thousands of dollars and it starts doing it again in a few months.

The brakes will go to the floor on its own and won’t stop and almost rear ended vehicles or ran lights due to not being able to stop. The brake issue has been reproduced and noted on service records. I am a 100% disabled veteran that requires a mobility scooter for mobility and appointments. The other issue is the vehicle will loose power anywhere and anytime and has to be towed in by AAA to the Infiniti dealership every time and they say the issue cannot be reproduced and I have gone thru their complaint system and they are in the process of sending technicians to finally look at the vehicle. I am afraid if this car because the last time it happened it almost killed me because it just lost power and brakes on an Oklahoma interstate at around 70mph and had to coast to the right side service area to wait for AAA was almost rear ended twice in the process of getting to a safe area. My family and I are in danger anytime we drive this vehicle and have an extended Infiniti elite warranty thru manufacture. The vehicle in question is a 2015 Infiniti QX60 and was purchased in 10/16/2019 with 24555 miles on it and have had problems with car since day one. Please Please help we do not want to die. We have all recorded messages where Infiniti makes excuse after excuse after excuse to do anything about our safety.

Vehicle keeps shutting off mid drive have to jump it to get it started. It runs ok for 1-2 days then dies again. Tested battery and checked alternator to no avail. The ac cooling fan goes up and down and draws a ton of power from the vehicle. All local mechanics can’t figure it out.

The radiator cooling fan malfunctioned on Infinity QX60 model after 39000 miles on the odometer. Engine cooling mechanism fails that may result in overheat/engine failure or potential fire. It is a known defect on infinity qx60 and Nissan Pathfinders. It costs $1200 to replace the fan assembly. Infinity is aware of this defect/faulty part and will not recall to correct the defect and put the burden on consumers to spend over a thousand dollars to correct the issue.

I’m reporting a serious safety issue with this Infiniti. Tonight while driving the engine just shut off. We fortunately were not in an accident, but easily could have been. What terrifies me is that this happened twice a few years ago. It was still under warranty so Infiniti inspected it and replaced the entire transmission. The warranty is expired, but this huge safety issue is still happening!

I HAVE NOTICED MY CAR STUTTER A BIT WHEN I ACCELERATE AT A LOW SPEED. IT HAPPENED INFREQUENTLY BUT AS TIME HAS GONE ON IT HAS GOTTEN MUCH WORSE. WHEN I BROUGHT TO DEALERSHIP THEY CHARGED ME $100 TO PUT IT ON THE COMPUTER TO REPROGRAM IT, OF WHICH I THOUGHT WAS ODD. IT WAS TOLD TO ME IN ORDER TO GET AN ACCURATE READING ON THIS MAKE AND YEAR THIS NEEDED TO BE DONE. AFTER DRIVING ANOTHER 1K MILES, IT WOULD REVEAL THE PROBLEM OF WHICH IS A VALVE SYSTEM ISSUE IN THE ENGINE THAT CAN LEAD TO A FAULTY TRANSMISSION. THIS IS A KNOWN PROBLEM FROM THE RESEARCH I'VE DONE. IT IS KNOWN THAT THE 2013, 2014 AND SOME 2015(IF MANUFACTURED IN 2014) INFINITI'S HAVE THIS ISSUE!! THE DEALERSHIP NOW RECOMMENDS ME FIXING THE WHOLE VALVE SYSTEM. THEY WILL GIVE ME A DISCOUNT BUT THAT THIS IS ON ME AS THE CONSUMER. THIS IS NOT A WEAR AND TEAR ISSUE, IT IS A KNOWN DEFECT THAT THIS MODEL/YEAR HAS AND IM VERY DISAPPOINTED THAT I HAVE TO PAY TO FIX SOMETHING THAT HAS BEEN AN EXISTING ISSUE WITH THIS CAR AND I'M NOT GUARANTEED THAT IT WILL CORRECT THE PROBLEM EVEN IF I DO FIX IT. AS A HUGE COMPANY AS INFINITI I WOULD THINK THEY WOULD STAND BEHIND THEIR CARS ESPECIALLY WHEN THE VALUE SYSTEM IS IMPERATIVE TO MAKE THE CAR WORK PROPERLY AND COULD LEAD TO TRANSMISSION FAILURE IN THE FUTURE!

THERE IS A VERY LOUD SPUTTERING FROM THE ENGINE WHEN I AM STOPPED. IT SEEMS AS THOUGH THE CAR IS GOING TO DIE. NO CHECK ENGINE LIGHT APPEARS. I TRIED REVVING THE ENGINE IN NEUTRAL TO SEE IF THAT WOULD RESOLVE IT, TO NO AVAIL. I JUST HAD MY STATE INSPECTION PERFORMED AT THE DEALER LESS THAN A WEEK PRIOR TO EVENT. NO ISSUES CAME UP AT THAT TIME.
