What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners report a consistent pattern of CVT transmission malfunction. The transmission slips or loses power at highway speeds and below 20 mph, sometimes acting as though in neutral despite the vehicle being in drive. This happens across all operating temperatures. When it slips, owners hear metallic sounds, experience jerking and bucking, and feel the vehicle lose ground speed even as engine RPM climbs. One owner reports the transmission sounds like it's slipping when heated after extended driving.
Two owners have experienced complete engine failure, with one stating the engine had to be replaced twice within two years due to CVT-related damage. One vehicle suffered a violent transmission failure at 70 mph that triggered airbag deployment.
The 4x4 system fails to remain engaged, which is particularly dangerous since owners purchased the vehicle believing they had a working four-wheel-drive system for winter driving. Nissan corporate admitted these vehicles are not safe for snow and no longer markets them that way, yet they were sold as such. One owner with children in the vehicle has slid into snowbanks multiple times.
Multiple dealership visits and diagnostics have failed to resolve these issues. Some shops misdiagnose the problem or cannot reproduce it. One owner had CVT fluid drained but the whining persisted. Nissan has refused warranty repairs citing mileage overages.

Failure modes owners describe
CVT transmission slipping and power loss
Transmission loses power and acts as though in neutral, or slips under acceleration and load. Occurs at highway and low speeds, all operating temperatures. Multiple owners report loss of engine power during acceleration, especially on hills or when turning.
When: Highway speeds down to below 20 mph; occurs after extended driving and heating; one case at 7,000 miles
Symptoms owners cite: Vehicle jerks, bucks, and creeps at low speed despite throttle input; Loss of ground speed despite high engine RPM; Metallic sound at low RPM with power loss; Transmission feels like it is slipping on acceleration; Vehicle acts as though in neutral while in drive; Whining sound after CVT fluid drain
Codes mentioned: Check engine light (repeatedly reappeared)
Repairs/costs cited: Two dealerships performed diagnostics and service on complaint #1 without resolving the issue. Complaint #9 mentions CVT fluid was drained. Complaint #7 received incorrect diagnosis (heat shield) and problem persisted. Repair shops in complaints #7 and #8 unable to reproduce or fix.
Recalls/TSBs owners mention: Complaint #2: Corporate mechanic stated the 4x4 drivetrain is 'set up to protect itself' and cannot be used for snow driving, contradicting vehicle marketing. Nissan refused warranty repair citing mileage overages.
Engine failure tied to CVT issues
Two documented cases of complete engine failure on the same vehicle, attributed by owner to CVT transmission issues causing engine to fail. Engine seized and would not turn over.
When: First replacement not even two years ago; second failure occurred subsequently
Symptoms owners cite: Engine will not start; Engine will not turn over; Vehicle at standstill and will not run
Repairs/costs cited: Owner states engine was replaced once due to CVT issues; failure repeated.
4x4 engagement failure
4x4 system does not remain engaged during winter driving. Vehicle supplied with cracked coupler from factory. After replacement, 4x4 still would not engage. Corporate mechanic claimed the drivetrain is designed to disengage for self-protection and is not suitable for snow driving.
When: From purchase (under 500 miles); issues persisted for years
Symptoms owners cite: 4x4 does not remain engaged; Vehicle loses traction in snow at low speeds (under 25 mph); Owner reports multiple incidents of sliding into snowbanks
Repairs/costs cited: Cracked coupler identified and replaced by corporate representative, but 4x4 engagement issue persisted. Transmission subsequently failed and Nissan refused warranty repair.
Recalls/TSBs owners mention: Corporate mechanic stated 4x4 is only for 'getting out of a jam' and not for driving in snow. Nissan corporate admitted they no longer market these vehicles as safe for snow. Warranty claim denied due to mileage overage.
Forward collision avoidance false activation with transmission slip
Forward collision avoidance system activates and applies automatic braking at highway speeds when no collision threat exists, coinciding with apparent transmission slip and reengagement.
When: Highway speeds; more than 10 occurrences
Symptoms owners cite: Forward collision avoidance warning light displays; Automatic braking applies without collision threat; Vehicle feels like transmission slips then reengages; Occurs with and without cruise control engaged
Repairs/costs cited: Repair shop unable to reproduce the issue.
Hesitation at moderate speed
Vehicle hesitated without warning at 60 mph. Persisted despite multiple diagnostic attempts.
When: At approximately 7,000 miles
Symptoms owners cite: Vehicle hesitates at 60 mph without warning
Repairs/costs cited: Coulter Nissan mechanic unable to duplicate failure. Battery replaced three times. Vehicle not repaired.
Recalls/TSBs owners mention: Manufacturer not informed of failure.
Violent transmission failure with airbag deployment
Vehicle experienced violent shaking at highway speed followed by loud explosion in front end, triggering deployment of front and curtain airbags. Assessed as possible internal CVT transmission failure.
When: Highway speed approximately 70 mph
Symptoms owners cite: Vehicle violently shakes; Loud explosion sound from front end; Front driver and passenger airbags deploy; Full right side curtain airbags deploy; No visible external damage
Repairs/costs cited: Tow facility and state trooper unable to determine cause; suspected internal CVT transmission failure.

Transmission slipping under close weather. Squeaky noise as well.
The transmission is going bad which makes it dangerous to drive. Had it 2 days and I check my FIXD module and found code. Took to where I purchased it and the drained cvt fluid and now makes a whinning sound and garage knows. U was told they inspected it before selling it to me. No codes where on dash either.
When driving at differing speeds, the transmission reduces, then stops applying power to the wheels, and acts as though it's in neutral. This has happened at freeway speeds, down to below 20 MPH, and a all operating temperatures. The brake pedal was not touched in conjunction with the gas pedal, and the vehicle was always in drive. This has now happened to us a minimum of 6 times, with no…

At what mileage does the powertrain typically fail?
Based on the 10 complaints filed, powertrain issues most often appear around 15,667 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
What does it cost to fix?
