Gas pedal unresponsive, then suddenly jerks the car forward – 2015 Nissan Rogue

ANSWER : 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.

ANSWER : Hi There,
It sounds like you may have low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

ANSWER : Hi there. When the engine is stalling and sputtering, this is an indication that the fuel system has lost pressure. Check the fuel pump relay and see if it is hot and if its clicking on when the key is turned on. If the relay is hot when the engine stalls or sputters, then there is an issue with the wiring to and from the fuel pump or the fuel pump maybe weak. For the steering column to lock up, the locking solenoid in the steering column losing power when the engine stalls. This could be an issue with the ignition switch as the solenoid is energized with the key turning in the ’ON’ position. The shaking could be either the brake rotors are worn causing the shaking when the brakes are applied or if the brakes are not applied, then the CV Shafts could have a joint that is felt when loaded when coasting. I suggest checking out the rotors, CV Shafts, the fuel pump relay, and the ignition switch. If you need further assistance with your engine stalling, shaking, and sputtering, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : The first thing you need to check for in a case like yours is air leaks. Check all the rubber parts and hoses under the hood for good condition and connection. The amount of fuel delivered to your engine is determined by the air that flows in and any air that gets in through a leak without being measured means less fuel being injected. There are of course a number of other possible causes; a failed Mass Air Flow Sensor for example, but they will require special skills and equipment to be examined. You can have this conveniently checked out by contacting Your Mechanic. They can send a technician to your home or office to check out your car and let you know exactly what it will take to solve your problem.

ANSWER : Hello. It sounds like you may have an issue with your throttle position sensor. This sensor sends a reference voltage to your power-train control module, which uses that to determine ignition timing and fuel trims. If the power-train control module is not detecting the proper signal from the throttle position sensor, the engine may not accelerate properly. It’s probably a good idea for you to have a professional mobile mechanic come to your location and complete a car is slow to accelerate inspection first, so they can pinpoint what is causing this issue to occur and they will recommend the right repairs be completed.

ANSWER : Hello – there are a couple of possibilities for the "failure to relearn" of the new throttle position sensor". If engine management recognizes an invalid parameter during the relearn process (low system voltage, AC compressor kicking on, etc.), it cancels the learning process and goes back to defaults. It is also possible that a wiring connection to the new TPS does not have a good connection. If checking for these issues, and going through the relearn again does not resolve this issue, I recommend a throttle control service performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, complete this repair, and get you back on the road again.

ANSWER : Hello. I usually start by checking the computer for codes. I also use the scan tool to see what the sensor are reading. Most of the time this is caused by an airflow sensor that is not reading right or a failing throttle body. It can also occur if the vehicle needs a tune up or if the timing belt is worn out and stretched. All of these need to be checked. If you need to have this checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your acceleration issue firsthand.

ANSWER : Hi There,
The check engine light is likely related to your gas cap not locking. This may also cause the jerking reaction as this is connected to the EVAP system in your car. Your car has a small purge valve with a purge solenoid in the Evaporative Emissions system that controls the venting of fumes from the fuel tank as these fumes build up inside, particularly when you are refueling the car with gas. The EVAP system prevents fuel vapors from the fuel tank from escaping into the atmosphere. I would recommend having an expert from Your Mechanic come to your location to diagnose and inspect your vehicle.
