2023 Nissan Ariya

At approximately 18,500 miles, my 2023 Nissan Ariya experienced a brake system failure while driving. The vehicle exhibited abnormal braking behavior and reduced braking performance, creating a serious safety concern. I was able to safely stop the vehicle, but the failure could have resulted in an accident. The vehicle was taken to a Nissan dealership for inspection. The diagnosis revealed severe and premature wear of the rear brake pads and significant damage to the rear rotors. The dealership also recommended replacement of the entire rear brake assemblies, not just standard wear components. The total repair estimate is approximately $3,800. Safety Concern: This failure occurred at very low mileage. In an electric vehicle with regenerative braking, brake components should last significantly longer under normal conditions. The extent of damage and need for full brake assembly replacement suggests a potential mechanical or electronic defect, such as a caliper malfunction or braking system issue. This was not normal wear and tear. The failure occurred during operation and posed a direct safety risk due to compromised braking ability. Manufacturer Response: The dealership has indicated the issue may not be covered under warranty, classifying it as wear-related. However, the severity and early failure strongly indicate an underlying defect rather than routine wear. I have contacted Nissan Corporate claims for further resolution. When visually inspecting the car the rotors were irregularly worn and the brake lines had burst spilling break fluid all over the rear innner tire .

Approximately 1.5 hours after taking possession of the vehicle, the Nissan Aria Evolve+ experienced a catastrophic brake system failure. Upon driving the vehicle home from the dealership (40 miles), the vehicle was parked inside the garage with the front facing the garage door. That is, it was backed in. 30 minutes later after arriving from the dealership, an attempt was made to drive the vehicle. As soon as it was put in drive, the vehicle started rolling forward even though the brake pedal was being depressed. Immediately it was clear that the brakes were not functioning. The vehicle continued heading towards the neighbor's house across the street. To avoid possible collusion vehicle was put in park and emergency brake engaged. This helped stop the vehicle. On the instrument panel, two different alerts were displayed while all this was occurring. The first one showed, "Warning, Malfunction See Owner's Manual." Then a second one was displayed, "Warning, e-Step system Failure. Press brake pedal to slow or stop." The following day, the vehicle was towed to dealership and they were able to replicate the issue. Service representative stated that Nissan would be notified so the can inspect the issue further.
