What is the reason for the exclamation mark displayed on the car dashboard?

[DeFrancisco]

The reasons for the exclamation mark displayed on the car dashboard are: 1. A triangle with an exclamation mark in the middle is a general fault indicator, mainly indicating parking sensor failure, overheating of the dry dual-clutch transmission clutch, fuel cut-off system intervention, or malfunction; 2. An exclamation mark inside a circle with parentheses is a brake system warning light, mainly indicating a fault in the brake system, low brake fluid level during driving, or the handbrake being engaged; 3. An exclamation mark in the middle below parentheses is a tire pressure monitoring warning light, which lights up when the pressure in one of the vehicle's tires is too low.

When that exclamation mark light on the car dashboard comes on, there could be several possible situations. The most common one is a problem with the braking system, such as low brake fluid or the handbrake not being fully released, which poses a safety hazard because driving becomes dangerous if the brakes fail. Additionally, it might indicate low tire pressure—many cars equipped with a TPMS system will trigger this light when tire pressure is insufficient—or an engine issue, like low oil pressure. Once when I was driving, this light came on, and it turned out the handbrake was stuck. I immediately pulled over to check, otherwise, it could have led to loss of control on the road. I recommend checking the owner’s manual first to identify the specific issue, then heading to a repair shop for diagnosis as soon as possible. Regular maintenance should also focus on these vulnerable components to prevent minor issues from escalating.

A dashboard warning light with an exclamation mark is usually an alert signal, potentially related to the braking system, tires, or engine. From my experience in auto repair, about 80% of cases involve brake issues—low brake fluid or an improperly released handbrake can trigger it. TPMS (Tire Pressure Monitoring System) malfunctions are another common cause, where the system automatically alerts you to low tire pressure. In rare cases, it could be an engine sensor error, such as low oil pressure. As a professional, I recommend starting with simple checks: ensure the handbrake is fully released and measure tire pressure. If the light persists, use a diagnostic scanner to read the trouble codes and pinpoint the issue. Remember, addressing it promptly can prevent bigger problems—don't wait until something serious happens to regret inaction.

Seeing an exclamation mark light up on the dashboard while driving can be quite alarming. I experienced it myself last time—it turned out to be due to low tire pressure. Alternatively, issues with the braking system, like the handbrake not being fully released, can trigger an immediate warning. Other possibilities include the engine fault light displaying an exclamation mark. This incident reminded me to learn more about car knowledge and refer to the manual to understand the meanings. A simple solution is to pull over safely, check for tire leaks or brake conditions. Developing a habit of quickly scanning the dashboard before driving helps detect issues early and avoids unnecessary trouble.
