| Power Train problems |
I am reporting recurring failures involving the vehicle's electronic control systems. These issues have been documented with the dealership on multiple occasions and a Nissan district technical service manager (dtsm) has also inspected the vehicle. Nissan has not been able to replicate the issues as they are intermittent. Braking system: when sitting at a stop light, where I had my foot on the brake, I heard a pump/whooshing sound from the front of the vehicle while the brake pedal suddenly traveled to the floor. On two separate occasions, the pedal has also become rock-hard. The Nissan dtsm was not able to replicate and suggested that the brake pedal becoming hard or going to the floor is "normal", and that my car showed no codes, and there was no recommended action required--that as long as the vehicle stopped, it was not a problem. After the dtsm inspected the vehicle, the brake pedal went fully to the floor five consecutive times while backing out of a parking space. I heard the same pump/whooshing sound from the front of the vehicle. Because I was backing up slowly, and the brake pedal was not responding to me given it was going fully to the floor, it was unclear how much braking power I truly had. The pump continued to make noise as the first few times I pressed the brakes driving away. Engine/transmission: when the gas pedal is released, the engine intermittently continues to rev, and not respond to throttle input as designed, requiring the use of the brake to force a shift. But, Nissan stated they are aware that there is "general dissatisfaction" with the transmission overall, and suggested I wait for a future software update in the hopes that it may address some of the concerns. Electrical/integrated components: failures include side mirrors failing to open or lock into position when driving. Audio/nav system: once when driving in an unfamiliar area, the audio/sound went out, with no turn by turn (or radio) sound at all, forcing me to watch the screen.
