2015 Infiniti QX60 Problems

What owners report

Complaints on the 2015 Infiniti QX60 cluster around the continuously variable transmission, which owners often describe as shuddering, jerking or hesitating under acceleration; many of these reports arrive around 50,000-75,000 miles. A second recurring theme is the sunroof glass shattering at highway speed without an apparent impact, usually within the first 60,000 miles. Passenger airbag warning lights and occupant-detection faults are also reported, mostly in low-mileage vehicles, alongside a smaller group of brake and stalling complaints.

   Transmission and drivetrain

   CVT shudder, jerk and hesitation

   • 26 complaints (28%)
   • median 70,070 mi at 5.0 yrs old (11 state mileage)
   • filed 2018–2026

   Owners describe the vehicle shuddering, bucking or hesitating while accelerating, at low speeds around 20-25 mph and also at highway speed, sometimes with the engine revving without the car picking up speed. Several complaints state a dealer diagnosed the transmission as failing and recommended replacement at the owner's expense; others say the dealer could not duplicate the symptom, found no code, or reprogrammed the transmission without resolving it. Some owners mention a warranty extension or a service bulletin rather than a recall. Mostly reported between roughly 25,000 and 100,000 miles, often worsening gradually over time.

   What to check: Ask whether the CVT fluid and calibration updates were performed and whether the transmission has been replaced or repaired; test drive at steady low speed and on an incline to feel for shudder or hesitation.

   “At approximately 40k miles, the dealer replaced the CVT because the car was bucking and created a code that the mechanics could see. That fixed the problem until a few thousand miles later; the car now jutters around 20-25mph on flat roads and very pronounced on inclines then produces a wobble throughout the car at speeds above 25mph. When I take my foot off the gas, the symptom stops. Both the service manager and transmission specialist took the car for a ride with me and experienced the symptoms. …”

   “We own this vehicle for almost three years, several time the transmission seems sluggish, shutter, and stop in high ways while it almost caused several accidents. I pulled it on side get it towed to dealership and was told the transmission failed and told to call Infiniti consumer services, I did that but was told to bad we can't do anything, it seems that several owners have the same kind of issues, and the Infiniti corporation knows about it. Here is the response I got from Infiniti customer service. …”

   Sunroof glass shatters while driving

   • 14 complaints (15%)
   • median 53,000 mi at 4.2 yrs old (11 state mileage)
   • filed 2016–2024

   Owners report the sunroof glass breaking suddenly with a loud bang at highway speed, with no object seen striking the roof and no prior damage noted. Complaints describe the remaining glass bowed outward and pieces falling into the cabin; most say the vehicle was simply driven or taken to a dealer rather than repaired at the time. Reported from about 23,000 to 85,000 miles, mostly at highway speeds and in varied weather.

   What to check: Inspect the sunroof glass for chips, prior replacement or aftermarket film, and ask whether the panel has ever been replaced.

   “I found out on saturday morning,that my sunroof was broken(looks like explode from the inside out),I checked from any stones or any debris(that could hit my car around my driveway,but there were nothing around the car and there were no marks on the roof as well).”

   NHTSA complaint #10903626, filed 2016-09, 44,600 miles

   “On 8/11/2018 at approximately 1315 cst I was driving in the right lane of I-10 w by mile marker 126 at the posted speed limit when the sunroof exploded. No vehicles were within 200 feet of our vehicle (Infiniti 2015 QX60) in daylight and clear visibility , no visible debris in roadway or vegetation overgrowth was present. The roadway was dry and in good condition. Sunroof was closed and had been operated less than ten times during the life of the vehicle.”

   Air bags

   Passenger airbag light on or detecting no occupant

   • 15 complaints (16%)
   • median 10,418 mi at 1.5 yrs old (11 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2015–2025

   Complaints describe the passenger airbag warning or "off" indicator illuminating with an adult seated, as if the occupant classification system treats the passenger as a child and disables the airbag. Several owners say dealers reset or replaced sensors without a lasting fix, and some mention work tied to an occupant-classification recall with parts unavailable or the warning remaining afterward. Often reported on very low-mileage vehicles, from new up to about 10,000 miles, with some later reports around 50,000-115,000 miles.

   What to check: Before buying, sit in the front passenger seat and confirm the airbag status indicator reads on for an adult, and ask whether the occupant-classification recall or sensor reset was completed.

   “We purchased a new 2015 qx 60 infinity in may, 2015. We noticed when my wife sat in the front passenger seat, the air bag light went on indicating the air bag would not deploy in an accident. During the 6 month servicing, I mentioned this to the infinity service dept. And was told they would reset the sensor to zero. They also said that if the system thought my wife was a child based on her weight, the airbag would be turned off. After the service the problem continued. …”

   NHTSA complaint #10873473, filed 2016-06, 10 miles

   “Because I bought the car used in June of this year, around July, the driver's and passenger's side airbag warning lights on the display panel started flashing, then disappeared after a few days. After August, they kept flashing and then stopped altogether. I took it to an Infiniti dealership for inspection, and the mechanic reported that the airbag sensors were malfunctioning and there was no connection between the airbags and the computer system platform, and that other problems might even be discovered during the repair process. …”

   Engine

   Engine stalling or losing power while driving

   • 9 complaints (10%)
   • median 75,000 mi at 4.3 yrs old (3 state mileage, few)
   • filed 2018–2025

   Complaints describe the engine stalling or dropping power while driving or idling, sometimes requiring a restart or tow, with no warning light in several cases. Owners report rough running or sputtering at a stop and, in some cases, coolant entering a cylinder; dealers variously could not duplicate the fault or quoted major engine work. Reported from about 30,000 to 100,000 miles, with some reports of rough running at hot idle or in warm weather.

   What to check: Ask for a scan tool history for stored and pending codes, check coolant level and condition, and look for records of misfire or cooling-system repairs.

   “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.”

   NHTSA complaint #11083369, filed 2018-04, 75,000 miles

   “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.”

   NHTSA complaint #11512763, filed 2023-03

Buying note. Given the transmission complaints, a thorough test drive at low and highway speeds plus a pre-purchase inspection by a shop familiar with this CVT is worthwhile, and reviewing service records for transmission, airbag-sensor and brake work helps set expectations.
