What Causes Sudden Unintended Acceleration?

Sudden Unintended Acceleration (SUA) occurs any time a car starts to accelerate independently and differs from what the driver intended. Possible reasons include the wrong operation of pedals, sticky pedals, floor mats, defective electronic throttle controls, and software problems. SUA can thus be prevented by proper vehicle maintenance and appropriate driver training. 

Accelerator Problems in Cars

The accelerator or gas pedal determines how fast your car will move. If it fails, your vehicle may accelerate uncontrollably.

1. Stuck Pedals

In some cases, this leads to a dirt build-up or wear and tear that causes the gas pedal to stick, making it challenging to release.

Again, floor mats that are either loosely fitted or placed incorrectly may interfere with the pedal and keep it depressed.

2. Throttle Cable Issues

Older cars utilize a cable rather than a fluid from the driver’s floor to the accelerator. If the cable becomes frayed or damaged in some other way, problems with the car’s acceleration or deceleration are highly likely.

3. Broken Sensors

Modern automobiles have sensors informing the engine of the measure of force applied to the accelerator pedal. If these sensors go bad, they send the wrong message to the engine, which speeds up.

Problems with Electronic Throttle Control

Most new-generation cars feature Electronic Throttle Control (ETC ), which does not comprise the throttle cable. However, as with any system, ETC enhances a car’s performance and has issues.

1. Software Errors

ETC systems rely on software to regulate the engine. Sometimes, the software has a bug, causing the car to accelerate when it was not supposed to.

Sometimes, car companies release campaigns to recall cars so that these problems can be rectified, thus the need to stay abreast of your vehicle.

2. Sensor Failures

ETC systems, like any other efficient system, depend on sensors to ensure system operation. If a particular sensor’s information is erroneous, the engine may behave abnormally and accelerate.

3. Electrical Issues

Damaged wires or loose connections may adversely affect the ETC system’s operation. These issues may confuse the car’s computer and result in an increased rate of acceleration.
