I have a very serious problem with the car that I consider a major safety issue. It has a CVT transmission and only 13,000 miles on it. When I'm driving and stop the car at the traffic light for instance, when it's time to accelerate, the gas pedal becomes unresponsive. I would press it, floor it but it just quits working. But, then, it would suddenly start working and the car would have such a violent jerk forward as if the RPM is over 3500. I went to the dealership and there are no error codes. The dealer doesn't know why this happens. The issue is intermittent.
Hello. The new electronic throttle systems are very sensitive to a driver using two feet to drive and if you are still touching the brakes and trying to accelerate it will not let you. This programming is due to all the problems in the past where some vehicles had problems with accelerating on their own and it could not be stopped. Now if the brakes are on the vehicle cannot be accelerated. If you are not touching the brakes, then your dealer will need to verify the problem to find a solution. Since your car is likely still under warranty, they may have these repairs covered.

An indication that a vehicle is not receiving the right mixture of air and fuel is if the vehicle jerks or surges forward at high speed.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
When a cars rpm goes up and the car is not picking up speed, this usually means that there is a problem inside the transmission. The valve body, shift solenoids, and or clutches of the transmission probably had gone bad or are worn out to the point they are causing a transmission shifting issue.
Usually when the car will `jerk` when you press the accelerator and lift from the accelerator, it`s likely due to clogged fuel injectors, damage to the throttle body or other fuel system components. It could also be due to worn out motor mounts or perhaps a small exhaust leak.
A Continuously Variable Transmission (CVT) provides simple, efficient power delivery creating better fuel economy than traditional transmissions. With CVT, shifting is seamless – the vehicle performs as though it has a variable gear for every driving situation, and you won`t feel any shift shock.
The problem: The continuously variable automatic transmission may shake, shudder, bump or vibrate during normal operation in certain Nissan vehicles, including select Altimas and Rogues. This is due to either a faulty valve body inside the transmission or the CVT needing to be replaced.
Loss of acceleration: Multiple Rogue years struggled with transmission problems, which got Nissan into a class-action lawsuit. The problematic transmission system is the likely culprit for the Rogue`s most reported issue: acceleration loss.
There are a few reasons why your car might hesitate when you press the gas pedal. It could be due to a problem with the mass air flow sensor, the oxygen sensor, the TPS, or the fuel filter. It could also be due to a clogged or dirty air filter.
If the RPMs are too high, try dropping it down a gear. This can solve the problem quickly and easily. Depending on what equipment the engine is hooked up to, you may be able to control the RPMs with gears. If the RPMs are too high, try dropping it down a gear.
If your engine revs up as you press down on the gas but your vehicle doesn`t accelerate as much as you`d expect, you may be dealing with transmission slipping. If you`ve ever tried to accelerate on ice, where your engine revs but your vehicle goes nowhere, you know the feeling.
In addition to vibrations, a damaged mount also causes heavy jerks and jolts when you change gears, as the transmission too is attached to the engine unit. This jerk can be noticed at higher speeds, or simply when you change gears.
Depending on the vehicle and the driver, a CVT can provide a smoother driving experience when comparing it to a traditional automatic. According to Carfax, one of the most significant advantages to having a CVT is that they are often more fuel-efficient than a regular automatic.
Pros of Continuously Variable Transmissions (CVT)
Unlike typical automatics, the CVT can change the gear ratio forever to maintain the engine running at peak efficiency. On the whole, the more gears offered in a typical automatic transmission, the better engine power is optimized.
The CVT unit will not last nearly if the typical automatic transmission. In fact, most of these units last around 150 000 kilometres or less. Even more important to note is the fact that when they fail, 9 times out of 10 they must be replaced.
Clogged Fuel Injectors
A clogged fuel injector can prevent the fuel your car needs to accelerate, thus causing you car to jerk in the process. If you hear your car engine stuttering, then the injectors may not be providing an adequate amount of fuel. To fix this, you should clean the injectors on a regular basis.
If your car hesitates when accelerating at low speed, you likely have a lean air-to-fuel mixture—meaning the gas getting to your engine doesn`t have the correct mix of fuel and air.
Rough starts, hesitation and poor acceleration are all common symptoms of a bad spark plug. If a spark plug or multiple spark plugs are faulty, they will have trouble creating the spark that causes the ignition process in your vehicle.
Power train and engine issues are a big concern for 2015 Nissan Rogue drivers, with one recall and over 100 complaints total, mostly having to do with the car accidentally shifting out of Park, and potential transmission failure.
Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
Bad gas can directly affect your ability to accelerate on the road. If any portion of your gas is not as quality as the rest, you may notice varying degrees of power, seemingly randomly, within even one tank of gas. It is important to test the acceleration power of a car when test driving any new or used vehicle.
4000 rpm is no problem, high rpm can wear down on the head where the camshaft rotates but that`s no really a problem until you get near 7000 rpm.
Typically, engines idle at about 600-800 rpm. Older engines may go up to 1200 rpm or more while warming up. But if the engine is revving up while idling, even after it`s sufficiently warmed up, you might have a problem. High idle speeds waste fuel, cause extra wear and tear on your engine, and can be unsafe as well.
At times, you may find your car`s RPMs high. RPM stands for Revolutions Per Minute. When this happens, your engine may start shaking and produce loud sounds. Unfortunately, these sounds also indicate a missing in your engine and can result in engine failure if you continue to drive your car with such a missing.
