Owner-reported complaints naming the powertrain system, filed with NHTSA
Data refreshed
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials. Every record below is an owner-reported complaint about the 2019 Nissan Altima submitted to NHTSA — not a confirmed defect, not a recall and not a manufacturer bulletin. 9 reports on file name it.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Engine and transmission disengaged from each other and I could no longer accelerate or keep speed. I had to pull over, turn off the car and turn it back on. Local shop took a look and confirmed a cooling System Failure. The system is not at the right pressure at operating temperature. Exhaust gasses in cooling system.
On August 30, 2025, while driving on the highway, my 2019 Nissan Altima displayed a “CVT (AT) Hot / Power Reduced” warning. Power was limited, but the engine did not shut off. I immediately scheduled service at Paul Miller Nissan in Fairfield, CT. At the September 2, 2025 visit, the repair order stated: “Customer states CVT (AT) Hot Power Reduced display in dash. All past codes stored; cleared all past codes stored.” No complete diagnostic test, CVT pressure test, or fluid inspection was performed. The dealership did not preserve the freeze-frame data from the TCM. I was told that no current fault codes were present and that the vehicle was safe to operate. Relying on the dealership’s professional assurance, I continued normal use of the vehicle. About a couple of weeks later, the vehicle began to jerk and lose smooth acceleration intermittently, worsening by the sixth week. I promptly returned for service. On October 21–22, 2025, the same dealership confirmed transmission codes P0776 and P17F0, diagnosing a CVT failure and recommending full replacement. When questioned about prior diagnostic data, the service manager stated that all data from the September visit had been cleared and that the freeze-frame information was deleted and no longer available. This handling contradicts Nissan’s standard CVT diagnostic protocol, which requires documenting stored codes, inspecting CVT fluid condition, and recording internal temperatures before clearing data. Nissan Consumer Affairs later stated their review relied solely on the dealership’s findings and that missing diagnostic data would not be retrieved. Since the confirmed failure, I have been forced to rent a vehicle at my own expense, exceeding $1000 to date. The vehicle’s reduced power and transmission failure created a serious safety risk, especially as I transport my children in this vehicle. The dealership’s erasure of diagnostic evidence prevented accurate evaluation and timely repair. The issue remains unresolved.
1st. I would like to report defective windshields, I've replaced it once and the one I replaced got a crack now also. I don't speed I don't tailgate I drive proper and my insurance records my driving. My car has less that 33k and I've owned it for 4 years. 2nd. I would to report crappy transmission, the car struggles to accelerate in times you need it most.

The problem was confirmed by the nissan dealer and the vehicle component has been inspected and replaced by Team Nissan, 70 Keller Street, Manchester NH, 03103 The symptoms of this problem were lots of vibration from the rear of the vehicle, a cyclical chirp while driving and a very loud squeaking noise ( Sounded like metal on metal) while reversing.
2019 Nissan Altima is experiencing judder when switching between gears at low speeds. Also automatic breaking system (ABS) activates when I attempt to park.
I got an 2019 Altima SR and my active grill shutter has gone bad already and my car is still basically brand new it only has around 56 thousand miles on it my check engine light is on because of it
The transmission failed /malfunctioned. It’s available for inspection upon request. My safety and the safety of others was put at risk when the vehicle stalled at a traffic light or in the middle of traffic. Took the vehicle to autozone to be scanned and they confirmed it was the transmission. The vehicle has not been inspected by the dealer yet because I would have to paid between $200-350 to have the vehicle towed to the dealership where the vehicle was purchased which is two hours away. The local dealership charges $130 to diagnosis my vehicle. There were no warning lamps or messages prior to the failure. The CVT message appeared on my dashboard after the vehicle stalled and would not accelerate more than 5 miles or would not move at all upon acceleration of the gas. In addition to the current transmission issue, I have also had the brake light switch adjusted twice. The failure of the brake light switch drained the vehicle battery resulting in having the battery replaced as well.
Vehicle has noise from rear differential . Dealership confirms the noise is the rear electric cuppling . Dealership states no recall or warranty for this concern . The 2019 Nissan Rouge which utilizes the same AWD system , including the same electric cuppling with the exact same part number has an open & active recall , yet Nissan has chosen to NOT recall the Altima . Dealership states they suspect "there's not many AWD Altimas to cause a recall." The fact that both vehicles utilize the same exact AWD system including the same cuppling with the same part # should warrant a recall across all vehicles utilizing that system , not just one .

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
