Meaning Of Triangle with Exclamation Point Honda

Vehicle stability assist system (VSA) issues are indicated by the triangle with an exclamation point on Honda vehicles. If this system isn’t functioning properly, driving could be risky because it’s intended to help keep the vehicle stable.

While driving, you may make a sharper turn than you intend. With the aid of the Vehicle Stability Assist technology, your Honda will be able to stabilize itself automatically. The VSA light also comes on for other reasons, for example, the VSA light will turn on if you use the incorrect oil or replace it too infrequently.

What Would Cause The VSA Light To Come On?

In this section, we will be discussing the causes of the warning with a yellow triangle and exclamation mark on the dashboard

1. Damaged VSA System

In some cases, the VSA program itself might be the cause of the problem. When this happens, the warning light will come on normally, however, it continues to stay on without flashing. It’s recommended to take the car to a mechanic to get it checked if this occurs.

2. Turning off VSA Accidentally

Your VSA system might accidentally get disabled especially when you aren’t paying attention to it. The traction control settings are frequently turned off unintentionally so this should not come as much of a surprise. When you find out the system was accidentally turned off, you can simply turn it back on.

3. Engine Problems

When your engine develops issues, the VSA light will come on. From simple issues like a loose gas cap to more serious problems like an oxygen sensor problem, any of these could be the root cause. 

Using low-quality oil will also cause major engine issues. Why? This is because Honda engines are made to function with a certain brand of oil. The VSA light may turn on if you use the incorrect or low-quality oil.

4. Varied tire sizes

Your car warning light will also come on when one or more of your tires are noticeably smaller or larger than the others. You will be able to easily notice this while driving because your car will be tilting to one side of the vehicle. 

The vehicle stability system depends on the tires having an equal size on all four wheels to function effectively. When it is faced with an anomaly, it is only natural for the warning lights to come on.

5. Oil change is due

Sometimes, the reason for a Yellow triangle indicates that oil changes are needed. For example, if this light appears every 5,000 miles on a Toyota Highlander, it reminds you to change your oil during service.
