Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2017 Infiniti QX60 owners, lightly cleaned up (personal details are redacted by NHTSA).
My vehilce only has 31000 miles on it and the cooling fan went out, was not due to anything that I did driving wise. When I called Infiniti Warranty Divison in Franklin Tennessee they said they are aware of the complaints by other customers they said they issued a technical bullentin ITB17-048 but said there was no reason for a recall but they deemed it necassry to make a design change which fixed this problem and also required a module change also. They said they are not responsible for the problem, but if that is true then why did they make the design change. So any owners with old design will have an issue and will have to replace the unit. So I am glad that I was not on the road driving and would have been stuck in the heat trying to get the car repaired. There was no warnings about the issues and even though they may the dealers aware of the issue no notice was sent owners. …
About a year ago, I was driving about 80 mph and the dash lights and radio just died, then within seconds everything came back on. It only happened that one time. The other day, I was on a busy highway headed home when my battery light came on. I just replaced both the alternator and battery less than a year ago. I started inching over to the left land (just in case) when the car just died and I had to coast to a stop in the middle of the highway WITH MY 3 KIDS!!! The police came and I was able to start the car and pull it on the shoulder, then a tow truck came and dropped it off at Infiniti. They had my car for 2 days and couldn't find anything and they told me to come and pick it up. Within 30 minutes of me picking it up, it did the same thing so I took it right back to Infiniti and dropped it off. Today, they called me and it was finally doing what I said it was doing. …
We bought the car used at about 24,000 miles. No engine lights were on. After about a month of owning it smoke would come from the exhaust when started. Took it in to be look at and was told it was a fuel injector and it was replaced. No more issues for about 6 months when it suddenly lost power on the interstate at dawn barley made it to the side of the road without getting ran over. Had to have it towed to a shop where I was told it was a bad coil and they replaced it. Went to pick the car up and less than a mile down the road it lost power again. Took it down for Infiniti to look at it. They said it had previously had engine sludge and that the warranty was voided because of it. After online searches, this seems to be a regular occurrence for this year and model. They recommend a new Engine for $14,000. Now stuck with a vehicle that won't run with a monthly payment I'm making on it.
The car died suddenly while driving. The battery is only a few months old. Prior to dying a few warning lamps suddenly came on but there was no prior warning. The engine did not overheat, there was no smoke, or check engine light until the car suddenly died. I have been advised that I need a new engine. I have been researching and it appears many others have similar issues with their Infiniti engines. Its [redacted] Please look into this. It's odd to me that so many folks engines have died at what is actually low mileage. It's also pretty frustrating and depressing, the repairs can go up to the cost of a new vehicle, when this appears to be a design flaw. I'm starting to meet way to many folks whose Infiniti or Nissan suddenly needs a new trans or engine as soon as the warranty ends.
Driving West on I8 from AZ into San Diego my vehicle would lose all ability to accelerate and start decelerating on the upward climbs of the Crestwood Summit highway pass through the Cuyamaca Mountains. Not only it would continue to lose complete driving power and we had to pull over many time to turn the car off and let it sit for 10 minutes. It was not over heated and no lights were on with any indication of failure. During decents and on plateaus it resumed its completely normal functioning. I immediately brought it in to Oceanside CA Infiniti where they told me they don't know what it wrong so they can't fix it and I have to basically drive back to AZ through the mountains again and break down (it's 115 degrees and almost 1.5 hours in both directions to any town) to figure out what was wrong. It's incredibly dangerous and clearly not safe
While driving the car the engine suddenly stopped completely and we rolled the car to the side of the road. Had this happened on the highway a bit earlier it could have been a major accident as it was snowing heavily and there were snow plows and semis at high speeds. For the next 15 min the car would start and engine would stop on trying to accelerate. After raising the engine in reverse the car stayed on and we were able to come home. (I found across similar experiences from other Infiniti owners online.) Note : at a little over 70K mile the car had an issue where the acceleration suddenly dropped while driving. Dealer told us the engine was shot and we had to replace the engine. The new current engine also had some instances of erratic acceleration but dealer said no issue was found on diagnostics.
The vehicle needs a completely new engine and I had made it known that I want to trade in the vehicle the very next day but was told that I need to wait until 30 days has past. I have reached out to the Loan institution and have documentation provided below of that INFINITI database in November of 2023 that this same vehicle needed a new engine. Both my children were hospitalized for breathing in these toxic vapors that were released from the tailpipe of the vehicle to which HGREG said they resolved and did not, as soon as vehicle started up the whole dealership came outside thinking someone's vehicle was on fire. Both my children are age 2 1/2 and 11 months old. Both were on breathing treatments due to the level of carbon monoxide released in vehicle while driving.
Vehicle began ticking in early 2023. Then received check engine light and trouble codes P0014 and P0017. Took to Infiniti dealership. Dealership claimed "sludge - you did not change oil regularly, " which I did - either at Valvoline, Wal-Mart, or by myself. Multiple online forums about Infiniti QX60 indicate all the dealership mechanics are saying the SAME thing to customers who are having this issue. Dealership claimed vehicle would need NEW engine priced at over $17,000!! They are doing this nationwide and globally. Infiniti KNOWS there is an engine defect leading to sludge and failed engine. My engine did fail in April 2024, but thankfully in my home driveway and not at high speeds - this would have been deadly had it happened on a major highway!
While driving, the vehicle displayed an engine malfunction warning followed by a low oil pressure warning. I pulled over and waited. The oil level was checked and was not empty. The warning lights briefly went out, but shortly afterward the engine lost power. When attempting to restart the vehicle, the engine began knocking. The vehicle became inoperable and required towing. This was a sudden engine failure with no prior indication of oil loss, leak, or neglect. This created a safety concern due to sudden loss of power while driving.
We bought the car used at 63,000 miles (approx.). At 65,000 (approx.) the engine will not crank. No engine lights were on. Infiniti will not acknowledge warranty due to engine sludge even though it has been maintained. After online searches, this seems to be a regular occurrence for this model and year.
