A faulty ignition coil, cap, rotor, or wires can cause your engine to stall. Usually, a weak spark will manifest as a rough running condition, but it can also shut an engine down entirely. Use a spark plug tester to diagnose if the problem is caused by a spark plug misfire.

A missing stopper pad is most likely the reason why your brake lights stay on when the car is turned off. Check for pieces of the broken stopper pad on the floorboard of the driver’s side foot well.

Step 1 – Check brake fluid Low levels of brake fluid will generally indicate a leak or the need of a brake pad replacement. Either way, low brake fluid will trigger the ABS/BRAKE warning light and you will need to add more fluid, so the caliper stays firm. If the pads are fine, there is likely a leak.

A backfiring or smoking exhaust can indicate either too much fuel or too little spark, both of which can bring about power loss. A backfire occurs when the fuel-air mixture does not fully ignite in the combustion chamber, but instead pops off elsewhere in the system.

A bad battery can cause a car to lose power while driving if the alternator cannot keep up with the battery’s charging needs. However, newer cars require more electrical power, which makes it difficult for alternators to deliver the required amount without assistance from batteries.

If the problem is a bad alternator, your car will slowly lose power. You’ll be driving down the road, your lights will dim, and you’ll lose power and die. Other problems can also cause a car to not start. It could be a bad starter, corroded cables, or a broken connection somewhere between the battery and starter.

Here are seven telltale signs that your car battery is dying:

1. A slow starting engine. Over time, the components inside your battery will wear out and become less effective.
2. Dim lights and electrical issues.
3. The check engine light is on.
4. A bad smell.
5. Corroded connectors.
6. A misshapen battery case.
7. An old battery.

Many people wonder if the car battery can die while driving, especially after their car battery died while driving. Obviously, answer is ‘Yes, a car battery can die while driving’. A cood car starting or dual purpose battery should not die while driving, but although it is rare event, it happens.
