2019 Nissan Sentra Reliability Score & Common Problems

Owners of the 2019 Nissan Sentra frequently report issues with the stop lamp switch, leading to brake lights failing to illuminate and intermittent starting problems. Complaints often describe the vehicle not starting unless the brake pedal is pressed multiple times or the car is jump-started. Many reports involve unresolved issues despite recall notifications, with parts being unavailable for extended periods. Approximate failure mileages vary, with some cases occurring as early as 3,200 miles. Safety implications are significant, with three crashes reported due to brake light failures or related issues, and one incident involving a fire due to a wiring harness problem. Potential buyers should be aware of these recurring issues and the associated safety concerns.

Owners of the 2019 Nissan Sentra frequently report issues with the vehicle's automatic emergency braking (AEB) system, which unexpectedly engages or malfunctions, sometimes bringing the car to a sudden stop without any obstruction present. This problem is often linked to a faulty front radar sensor and is described in situations such as driving at highway speeds or encountering minor road bumps. Brake pedal issues are also noted, where excessive pressure is required to start the vehicle or the pedal goes to the floor during use. Complaints suggest these problems can occur at varying mileages, with one report noting a failure around 38,000 miles. Safety implications are significant, as one complaint involves a crash, and others describe near-miss situations due to sudden braking. Used car buyers should be aware of these potential issues, particularly concerning the AEB system's reliability.

Owners report recurring issues with the airbag system in the 2019 Nissan Sentra, particularly noting failures to deploy during crashes and unexpected deployments without collisions. Complaints frequently mention airbag non-deployment in crashes, sometimes resulting in injuries, with incidents occurring at various speeds and situations, including rear-end and side impacts. Additionally, some owners describe airbags deploying randomly while driving, leading to injuries from the deployment itself. The reported mileage at the time of these incidents varies, with some vehicles having as low as 24 miles and others around 53,000 miles. These issues present significant safety implications, as non-deployment during a crash can increase the risk of injury, while unintended deployment can cause harm and obstruct the driver's view.

Owners report several issues with the Forward Collision Avoidance system in the 2019 Nissan Sentra, particularly with the Automatic Emergency Braking (AEB) and Forward Collision Warning (FCW) systems. Complaints frequently mention the AEB failing to engage when necessary, or conversely, activating suddenly without apparent cause, sometimes causing abrupt stops. Some owners describe malfunction indicators, such as warning lights and beeping sounds, with instances of the system engaging unexpectedly at highway speeds, leading to potential safety risks like fishtailing or loss of control. Several reports indicate these problems occur around 56,000 miles or earlier. Additionally, issues with sensor calibration, often attributed to the physical design of the sensor bracket, are noted as contributing to the unreliability of the system. These factors could pose safety concerns for potential buyers considering a used model.

Owners of the 2019 Nissan Sentra frequently report issues with the vehicle's speed control related to the front radar sensor and automatic braking system. Common symptoms include the activation of warning lights, unexpected loss of acceleration, and malfunctioning collision detection systems, often triggered by minor road bumps. Complaints indicate these issues can persist shortly after purchase or repair, with some owners experiencing repeated problems within a few months. Safety implications are significant, as one report involves a crash where the vehicle unexpectedly accelerated in a drive-thru, resulting in a collision and the car being declared totaled. Buyers should be aware of these potential issues, especially concerning the radar sensor's influence on speed and braking systems.

Owners report recurring transmission issues with the 2019 Nissan Sentra, often before reaching 100,000 miles. Complaints frequently mention symptoms such as the vehicle shaking, jerking, slow acceleration, and jumpy RPMs, with one owner noting specific issues when shifting into third gear. The problems are sometimes accompanied by a complete loss of acceleration, which in one case led to the vehicle rolling backward on an incline, indicating potential safety risks. Multiple owners describe having these issues persist over several years, with some experiencing them within the first few months of ownership. These patterns suggest potential transmission defects in vehicles manufactured during this period, which may be relevant for those considering purchasing a used model.

Owners of the 2019 Nissan Sentra frequently report issues with the steering wheel controls and dashboard electronics. Common symptoms include steering wheel buttons functioning intermittently and the dashboard screen freezing, which affects Bluetooth and radio functions. Complaints often describe these issues occurring after extended driving periods, typically over an hour, and mention multiple service visits without resolution. Some owners also note the malfunction warning light and steering wheel misalignment, which they find concerning. While no crashes or loss of control are reported, the recurring nature of these problems and the related safety warnings could be important for potential buyers to consider.
