When the slip ligth shows up on the dash board. Why can’t I speed beyond 30 mph?

The slip light suddenly appeared on the dash board and stays on. I feel traction when i try to speed up so i have to stop completly and turn off the car. I turn on the car and the light disappears then the car acts normal. I have happened to me 2 times now. I am wondering what could be the reason for it. Thank you in advance!

My car has 120000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello, thank you for working on this. The Vehicle Dynamic Control system is responsible for keeping the tires from spinning out or locking up in certain driving conditions. Your owner’s manual will have the best information on how to disable this traction control. If the module is activating when it should not be, then there is an issue with the system. Have the vehicle scanned for diagnostic troubleshooting codes to see if the computer has detected any issues. The wheel sensors may be defective or have an issue. More electrical and system testing will need to be done. For more help with servicing the system, you may contact our service department for a quote or to set up an appointment.

The traction-control light is usually a sign that your vehicle is working properly by maintaining traction on a slippery road, but it can also mean that your car has some damaged sensors or wires. Keep yourself safe on the road by taking your vehicle to a trusted auto repair shop at the first sign of trouble.
A Nissan traction control warning light can mean two things—if it briefly turns on in rough conditions, your traction control system is keeping your vehicle stable. But if the light stays on, the system is disabled, which can put you at risk.
The slip indicator light would be the same as the traction control light. If you are actually slipping out in this light comes on that is normal. However if the light stays on during normal driving, this indicates an issue with the traction control system.
When this warning indicator light comes on in the dashboard, this could be an indication of several issues such as faulty wheel speed sensors, a faulty steering angle sensor, a faulty rotational speed sensor or a problem with the steering rack.
If the slip light is on, is it safe to drive? The light indicates the traction control is functioning. Without traction control, when you drive, your vehicle may be susceptible to sliding or spinning out on the road. The TRAC system in your car should be shut off if you are stuck in the dirt, snow, or mud.
Works in the background to help accelerate and prevent wheel slippage (or “over-spinning”) when driving on slippery surfaces. Traction control is most effective when accelerating from a stopped or slowed position, or when trying to accelerate up a slippery hill.
The VDC and Slip Light illumination could be an indication that you are getting low on brake fluid, due to worn brake pads. Low brake fluid could cause the throttle control to kick in when a sudden vehicle movement is made, causing the vehicle to lose speed.
Quickly depress the gas pedal three times. Next, fully engage your engine and let it run for a minute. If there is no underlying issue with your traction control system, the TCS and ABS lights should reset and disappear.
Common signs include the Traction Control System (TCS) Light coming on, TCS not turning off/on, and loss of TCS or ABS features.
The magnetic operation on the traction control sensors or Anti-lock Braking sensors can be interrupted by dirt or other buildups. Another common sensor problem is with the electrical connections between the sensors and the vehicle`s computer.
What does the car sliding icon mean? The car sliding icon means that the Traction Control System is on. It helps you maintain the car`s stability in tricky driving conditions.
If the traction control light won`t turn off, there can be some reasons. One reason could be that the fuse for the traction control system has blown. Or it could be that there is a problem with the traction control sensors causing the light to stay on.
Hi There, The Stability Track light relates to the vehicles traction control system. When the computer detects an issue with this system, it will often times put the vehicle into a reduced power phase in an effort to prevent further damage and to keep the passengers safe.
Wheel-speed sensors are supposed to detect when one drive wheel is spinning faster than the others — meaning the vehicle is slipping or losing traction. The system will then reduce power and/or apply the brakes to that wheel.
Press the gas pedal 3 times in quick succession. Then, turn your engine on all the way and let it run for a minute. The TCS and ABS lights should reset and go away if there isn`t any underlying problem with your traction control system.

My car is hesitating / jerking at speed intervals of 20 mph, 30 mph, 35 mph and 40 mph.
ANSWER : This may be a sign of a dirty or failing mass air flow sensor. The mass air flow sensor is a unit in the intake system that monitors air intake as it is mixed with fuel prior to being injected into the motor. When this fails, this can cause an imbalanced air/fuel load to be supplied to the motor which results in an over fueling or under fueling situation depending on the conditions. This may cause a hesitation, loss of power or jerking reaction when this sensor is malfunctioning. When this is not working properly, you may also notice a strong smell of fuel. I would suggest having a professional from Your Mechanic come to your home to diagnose your mass air flow sensor.

When my speed reduces to around 30 mph, I feel a semi heavy jerk.
ANSWER : Hi there. This is a normal condition to the vehicle. As the transmission wears and gets lots of miles on it, it will tend to make the downshift solenoid work harder and the return spring gets weak. Also, if the engine is throttled hard and then let off and throttled again, the computer will be confused and force the transmission to shift hard into the next gear making the transmission jerk. If the problem continues, I recommend replacing the downshift solenoid and flushing the transmission fluid. A transmission service can solve many issues with transmission with high mileage.

If you need further assistance with your transmission jerking, then seek out a professional, such as one from Your Mechanic, to help you.

While driving at a speed of 40 mph all at a sudden the car speed dropped to 10 mph and stopped with solid check engine light
ANSWER : Hello. Warning lights accompanied with stalling can be caused by many things. If the oil is low I would go ahead and top it off to prevent the possibility of engine damage, however, it is unlikely that low oil is what caused the stalling. Stalling is most commonly caused by issues with the ignition, engine management, or fuel systems. If one of the components, such as a major sensor, the fuel pump, or the ignition coil, go out or have an issue they can cause the engine to stall. If the vehicle is no longer starting then it may be possible that there is an issue with the electrical system as well, perhaps a faulty battery or alternator. If the alternator goes out it will eventually drain the battery, which could also cause stalling. Scanning the computer for trouble codes, once the vehicle is started, will likely reveal some insight into what the issue may be. As the possibilities could be many, I would recommend having a professional technician, such as one from YourMechanic, come to your location diagnose what may have caused your vehicle to stall.

Transmission slips if I shut truck off and restart it will do fine for a few seconds then slip again
ANSWER : Hi there, thanks for writing in.

The reason is starts slipping at 30 is this is where it needs to change to second gear or third gear. The problem is most likely the servo piston for the second gear engagement is binding in the transmission housing due to a worn housing. The fix is to overhaul the transmission and have a sleeve put into the housing during the overhaul with an oversize servo kit. The only other fix would be to replace the transmission with a new or rebuilt unit. The reason it works after turning the car off and back on is because it sets a fault for itself and goes into limp mode, and turning it off will erase that fault until its seen again, at which point it will go into limp mode again. You can have this diagnosis verified by a qualified technician, such as one from YourMechanic, who can then provide you with a suggested repair plan.

ANSWER : Hi there, thanks for writing in.

It sounds like you are having a serious electrical malfunction, which is very hard to diagnose without being able to look at the car first hand. The first step to diagnosing your electrical issue would be to scan all the relevant control modules in the vehicle, to see if there are any faults relating to any of these issues. It sounds like somebody at the dealer has been trying to fix this problem, so it may be a more involved one. I have personally seen failed control modules cause things like this, but that is no guarantee that it’s the problem in your case. It would be best to have a qualified independent technician, such as one from YourMechanic, look at your car to diagnose your electrical problem.

speed odometer isn’t showing the speed and abs light is on
ANSWER : Have a certified technician diagnose why the abs light is on. There are a number of sensors that the abs system relies on to determine things like vehicle speed, individual wheel speed, throttle and brake pedal positions,etc. If any one of these are faulty, the abs light can come on. That your speedometer is not working along with the abs light, the vehicle speed sensor is the most likely culprit, but again, with so many sensors and electronics involved, it’s best to have a certified technician determine exactly what is causing the system fault.

I have a 2000 buick lesabre and my transmission is slipping and it wont go over 30 mph and i never had transmission service sent i
ANSWER : If the transmission has never been serviced, it’s likely that it is worn internally and requires a rebuild. The clutches wear and that debris floats around the transmission, causing faster wear and wear to most all components. That it has gone nearly 300,000 miles without a service is frankly, amazing. You can try having the fluid and filter changed but it may not make a difference. Have a local transmission specialist give you their recommendations.
