2019 Nissan Altima Reliability Report

Owners report that the 2019 Nissan Altima frequently experiences issues with the automatic emergency braking (AEB) system, which often engages without any obstruction present. Complaints commonly describe the vehicle braking abruptly and unexpectedly, sometimes while driving under bridges or in parking lots, leading to potential safety risks. Several reports involve crashes, with one incident also involving a fire and injuries, highlighting serious safety implications. The issues are often noted in vehicles with mileage ranging from approximately 2,300 to over 46,000 miles. Buyers should be aware of the potential for sudden braking and the possibility of brake system malfunctions.

Owners report that the 2019 Nissan Altima frequently experiences issues with the automatic emergency braking (AEB) system, which activates unexpectedly without any apparent obstacles. Complaints often describe the vehicle suddenly applying brakes, sometimes at highway speeds or in parking garages, creating a risk of rear-end collisions. These incidents are reported at various mileages, with some occurring shortly after purchase. Several owners mention warning lights for the forward collision system, and some report these issues persist even after attempts to address them at dealerships. The unexpected braking and warning light malfunctions present potential safety concerns, making it important for prospective buyers to consider these factors.

Owners report multiple issues with the power train of the 2019 Nissan Altima, particularly involving the CVT transmission and rear differential. Complaints frequently mention transmission failures, often characterized by reduced power, hesitation, and an inability to accelerate, with some reports of the vehicle stalling. These issues are noted at various mileage points, including as low as 8,200 miles. Additionally, problems with the rear differential, such as vibrations and noise, are reported. Safety implications include potential risks when the vehicle stalls or loses power unexpectedly, which could be hazardous in traffic situations. This information is crucial for potential buyers considering a used 2019 Altima, as it highlights recurrent power train issues that may affect vehicle reliability and safety.

Owners report that the 2019 Nissan Altima frequently experiences airbag non-deployment during crashes, with several incidents leading to injuries and one involving a fire. Complaints often describe the absence of warning lights or system alerts prior to these failures. A pattern emerges with issues related to the occupant detection sensor, which malfunctions and requires repeated resets or replacement, typically at mileages around 24,000 to 57,000 miles. Additionally, one report details airbags deploying under the steering wheel, causing injury. These issues present significant safety implications, as airbags are a critical safety feature, and potential buyers should be aware of these recurring problems.

Owners of the 2019 Nissan Altima frequently report suspension-related issues, with several noting abnormal noises such as clunking, banging, or grinding, particularly when turning or driving at various speeds. Complaints often mention worn tires and defective shocks or axles, with some issues arising as early as 800 miles and others around 45,000 to 60,000 miles. Two incidents involve crashes, one resulting from a wheel detachment that led to a collision, and another where suspension problems followed an impact. These reports highlight potential safety implications, particularly concerning wheel integrity and vehicle control.

Owners report several recurring issues with the 2019 Nissan Altima's vehicle speed control. A common problem involves delayed acceleration, where the car takes 3-5 seconds to respond after pressing the gas pedal, sometimes accompanied by engine stuttering or jerking, particularly noted around 45,000 miles. Another frequently mentioned issue is unintended acceleration, with vehicles accelerating without pedal input, requiring drivers to use brakes or shift gears to regain control. Additionally, owners describe malfunctions with adaptive cruise control and forward collision safety features, including sensor failures and unexpected braking, often occurring in vehicles with less than 1,000 miles. These issues can lead to potential safety hazards, such as increased collision risk due to unpredictable vehicle behavior.

Owners of the 2019 Nissan Altima report issues with steering, including sudden steering wheel lock while driving, leading to loss of control and crashes. Two complaints involve crashes, one of which resulted in an injury. Symptoms described include the steering wheel locking in a turning position and failure of the emergency braking system to engage during an incident. These issues typically occur at low speeds and in clear weather conditions. Buyers should be aware of these potential steering and safety system malfunctions, particularly as they may lead to severe safety implications such as crashes and vehicle damage.
