Unsurprisingly, a car jerks when braking if there’s a problem with the brakes.
Further, you’ll feel some vibration as you apply the brakes, causing a slight jerk to the vehicle as you come to a stop.
The problem may only be air in the brake lines.
If that’s the case, use a brake bleeder kit to bleed the brakes.

What causes your car to jerk when changing gears?
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
What would cause a car to hesitate on acceleration?
A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump. Fuel injectors may become dirty over time and not be able to provide as much fuel to the cylinder as is needed. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.
What are the signs of a bad transmission?
Here are five signs of transmission problems you should not ignore:
- Transmission slipping. If you’re experiencing automatic transmission slipping, it can feel like you’re driving in a certain gear and then it changes for no apparent reason.
- Rough shifts.
- Delayed engagement.
- Fluid leak.
- Transmission warning light.
Why is my engine light on and car jerking?
When your car is jerking around, this means that the engine is having a misfire and causing the engine to stumble making the vehicle seem to jerk around. Check the camshaft position sensor for any damage and if the harness is secure to it. Check the spark plugs and wires to see if they have any burn marks on them.
What does it mean when you accelerate and your car jerks?
Fuel lines are responsible for the flow of gas throughout the engine system. If it is faulty or if there’s a leak somewhere, a pressure is lost, thus causing the car to jerk. A disruption in the flow of fuel from the tank to the engine will cause the car to hesitate during acceleration, which will then cause a jerk.
How do I know if my CVT transmission is going bad?
Transmission Trouble: 10 Warning Signs You Need Repair
- Refusal to Switch Gears. If your vehicle refuses or struggles to change gears, you’re more than likely facing a problem with your transmission system.
- Burning Smell.
- Neutral Noises.
- Slipping Gears.
- Dragging Clutch.
- Leaking Fluid.
- Check Engine Light.
- Grinding or Shaking.
How do I know if my shift solenoid is bad?
Signs You’ve Got a Bad Shift Solenoid
- The check engine light comes on: The TCM continuously monitors shift solenoid operation.
- Erratic shifting or shift slippage: The shift solenoids regulate the flow of hydraulic fluid for shifting.
- Transmission won’t shift gears: A faulty shift solenoid can prevent fluid pressure from activating the appropriate gear.
What are signs your fuel pump is going out?
Symptoms of a Bad or Failing Fuel Pump
- Whining Noise From the Fuel Tank. One of the first symptoms of a problem with the fuel pump is a loud whining sound.
- Difficulty Starting.
- Engine Sputtering.
- Stalling at High Temperatures.
- Loss of Power Under Stress.
- Car Surging.
- Low Gas Mileage.
- Car Will Not Start.
Why is my car sluggish when I accelerate?
Defective Fuel Pump: The fuel pump pulls the fuel from the gas tank to the engine via the fuel lines. If the pump stops working, malfunctions, or becomes clogged, it will not supply enough fuel to the injectors. This can cause the vehicle to accelerate slowly, or even sputter and stall, especially at high speeds.
What does it mean when your car struggles to accelerate?
A slow accelerating car is the result of this incorrect data. It may also trigger the Check Engine Light. Other causes of poor acceleration are vacuum leaks, a defective throttle position sensor, a defective idle air control valve, and a plugged catalytic converter.
