Problems with 2014 Nissan Altima POWER TRAIN

The steering wheel starts to shake and i feel my gas pedal vibrate when driving approx. 30-40 mph and up. nissan technical services mechanic said that is normal for nissan altima 2013/2014. *tr

Tl* the contact owns a 2014 nissan altima. while driving 15 mph, the vehicle jerked. the failure recurred intermittently. the vehicle was taken to the dealer where it was diagnosed, but the failure could not be determined. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 1,000.

2014 nissan altima sl 2.5 makes allot of noise and vibration when you accelerate to get up to a highway speed whether it is from the engine or transmission it is very loud inside the car! the steering wheel seems to have a lot of play in it at a dead stop with engine running by turning the wheel right to left! you also hear clunking noises turning it right to left! the fuel in the tank makes loud swishing noises sort as if i have a small ocean in my fuel tank!

While attempting to make a turn at a stop light, vehicle began to shake and slow down. it felt as if it was going to lose power. i had to push the accelerator harder than expected as there was another vehicle bearing down on me in oncoming traffic. this is a new vehicle. i brought it to the dealer and it appears to be a torque converter issue. the shaking is not an issue in itself, however it could lead to accidents if someone is making a turn and needs to get out of oncoming traffic as the transmission does not seem to respond as expected. *js

The vehicle has a push button start/stop. when the car is turned off the vehicle can be left in gear and the audible warning indicators are confusing and inconsistent. as i was walking away from the car it would not remote lock. i looked back and it was rolling across the parking lot. any number of times i have left it in neutral by mistake. the audible warning system is terrible, inconsistent and this is dangerous. i called the dealer and was told there is no fix and you have to put the car in neutral and nissan said they don't accept redesign suggestions over the phone. i had to jump in the car with a bad back and hip to stop it as it rolled across the parking lot. very dangerous. audible door open and lights on warnings are inconsistent as is the key recognition system. i would not have bought this car if i knew it had such a dangerous flaw and bad electronics. my phone message has not been returned.
