If it has jumped too much the Cube may not even fire. If the timing is off a little and the engine still runs, the timing belt may have skipped. The timing chain (or belt) is responsible for keeping the upper valve train synced with the crankshaft. Nissan Cube: Bad Fuel Filter → Symptoms and Diagnosis If this is the case, like the catalytic converter, it’ll feel like everything is fine until you hit a certain speed, and then it’s going to bog down again. Nissan-Cube Catalytic Converter DiagnosisĪ bad fuel filter will not let enough fuel into the Cubes fuel injection system to support operation above a certain demand on the engine. This can also be a sign that it’s not getting enough fuel as well. Maybe it’ll drive 20 miles an hour just fine, but after that it just doesn’t want to accelerate whatsoever. If the catalytic converter gets too clogged up, it’ll keep the motor from accelerating properly. Here are some common issues that can affect the motor: The issue is going to be something affecting the motor.
If your Cube won’t accelerate, but the RPM’s do not change, that is an indication that there is an issue with creating power. Eventually it’ll only move in first gear or not at all. It only gets worse as the clutch disk slips, burns up, and can handle less and less torque. This will usually happen at highway speed, under heavy acceleration. Slipping means that it loses its grip on the flywheel and it feels like you’ve pushed the clutch in. When the clutch can’t hold on anymore, it’ll start to slip. The clutch is responsible for making a direct connection between the engine (via the flywheel) and the transmission (via the input shaft).

Automatic transmission are very complicated.Īlthough the manual transmission is going away, if you happen to have a Cube equipped with one, a bad clutch can cause it not to accelerate. If it can no longer shift, it could be caused by a solenoid/valve body has gone bad, clutch packs, debris, and much more. If something has gone wrong in the transmission, your Cube may not be able to accelerate any more. You also wouldn’t feel the slight jerk your Cube as you put it into gear.
If this were the case, there would not be any movement whatsoever from the vehicle. If you’ve broken a drive/axle shaft, your Nissan Cube’s transmission has no way to turn the wheels anymore. If the torque converter has gone bad, it will no longer be able to do this job. The torque converter is responsible for taking the mechanical power of the engine and converting it into hydraulic power. This is the number one cause of not accelerating but the RPM’s Go up.
You should check the transmission fluid immediately.
The power goes to the torque converter, and that’s the end of the line. If your Cube is too low on transmission fluid, it’ll will no longer be able to transfer power to the rear wheels. Here are the most common cause of acceleration with the RPM’s going up: This is typically a transmission related issue. Somehow, the power that your engine is creating is not making it to the rear wheels. If your Cube won’t accelerate, but the RPM’s go up it’s usually not going to be an engine related issue. They can provide valuable insight as to what the problem may be, and really help you narrow down the problem.

There is a section for each scenario with likely causes for each.īefore looking into anything else, if your check engine light is on, get a code scanner and see what trouble codes are stored in the computer system. Diagnosing the issue can be narrowed down by whether the engine is still revving when you push the gas or not. There are a lot of different reasons that can cause this. If your Nissan Cube won’t accelerate, that is a serious cause for concern.
