Car jumping when stopped is a frustrating issue that can cause safety concerns. Fortunately, there are some simple steps that can be taken to resolve the issue.
The first step is to check the transmission fluid level. If it is low, topping it off can often help. In other cases, the jerking could be caused by the air filter. If the filter is clogged, replacing it will often solve the problem. Another possibility is that the spark plugs are dirty or damaged. If the spark plugs are not firing properly, it can lead to engine misfires and a jerking sensation. Damaged electric parts like the crank sensor can also be a source of a lurching sensation when stopped.
Another solution is to use a battery jumper cable to connect to a working battery and start the car. This will help to temporarily solve the problem and get you safely back on the road.
Finally, it is always a good idea to practice controlled braking when you are out on the highway. This method is much safer than slamming on the brakes, as it will allow you to steer around obstacles and stop your car at a safe distance.
It is also important to perform routine car maintenance to prevent this problem from occurring in the first place. Be sure to follow your owner’s manual for recommended intervals and keep up with regular service. Additionally, be sure to visit a mechanic for regular inspections and repairs, as this will help to catch potential problems before they escalate.
