Your Renault car’s dashboard may display a warning that states “Engine Failure Hazard”. This warning can make you feel uncomfortable and anxious. There are several reasons why your Renault dashboard might display this warning, despite the fact that this is something to be concerned about.
Meaning Of “Engine Failure Hazard” Warning on a Renault
An engine failure hazard alert is displayed on Renault vehicles including the Renault Clio, Trafic, Fluence, Grand Scenic, and Laguna 3 when the engine control unit (ECU) recognizes an engine failure or overheating. An onboard diagnostics warning, which comes from the vehicle’s computer, informs the driver that a problem has arisen.
It may be that there are issues preventing the engine from running as intended due to this dashboard warning light. Minor issues like malfunctioning oxygen (O2) sensors can have varying degrees of severity, while more significant concerns like a damaged thermostat can have greater severity.
What Causes an Engine Failure Hazard Fault on a Renault?
The following message will appear on your Renault dashboard based on my extensive research and years of auto mechanic experience:
1. Faulty Catalytic Oxygen Sensor
You might want to check this out if your Renault suffers from engine failures. Further, it is one of the easiest to repair as well.
Your engine’s exhaust can be monitored by an oxygen sensor because it tells you how much oxygen is present. When the oxygen sensors indicate that the fuel/air mixture is too much or too little, the powertrain control module (PCM) checks it.
You can ensure that all fuel is used in your Renault in this way, and your car will run more efficiently and correctly. In the event that these sensors fail, there is a high risk of damage.
You will see the “Engine failure hazard” light on when both of your sensors do not work properly. You might experience misfiring or poor performance when the airflow to your engine is not sufficient, especially during warm weather.
2. Leaks Prevent The Radiator From Getting The Proper Coolant:
Renaults also commonly experience this problem due to a leaking radiator. Renault radiators are designed to cool engines, so if there is not enough coolant, the engine will overheat.
In order to determine whether this is the case, here are some signs and symptoms to look for:
- When the weather is warm.
- As soon as the car is started, white smoke is released from the exhaust pipe.
- The vents or undercarriage of your car are leaking coolant.
Renault’s computer will tell you if the engine is failing if it receives hotter temperatures than normal.
3. Broken Thermostat
It is essential that the thermostat of your Renault be functioning properly for the engine to run at the right temperature.
Air is allowed to flow into and out of the radiator by operating a valve in the coolant system. Maintaining the engine’s temperature this way helps keep the engine running smoothly.
Renault thermostats may not allow you to change engine temperature if they are stuck in the open position. It is possible for an engine to fail if it is made too hot, which is known as the “Engine failure hazard”.
It is important to monitor the coolant temperature closely if you receive this error message. It would cause a leak in the radiator, not enough coolant, or damage to the thermostat if it is set too high.
4. Not Enough Motor Oil
In order for Renault moving parts to operate smoothly, oil controls temperature, lubricates, and cools them. Occasionally, a car can seize up due to insufficient oil.
It is important to check the oil level and change it as necessary if you have not done these tasks recently. The engine failure hazard fault message will indicate that there is too little oil in the engine. Add more if necessary. There is too little oil in the engine, so that should be the reason.
5. Faulty Spark Plugs
In the event of faulty spark plugs, the engine failure hazard may appear. Depending on how much pressure you apply, you may cause the engine to produce less power, or it may even stop running altogether.

How To Fix Engine Failure Hazard Renault?
In order to fix and reset the “Engine Failure Hazard” light on a Renault, it is typically necessary to figure out and resolve the cause of the warning. Identifying and resetting the warning light is as easy as following these steps:
1. Diagnostic Scan:
- A diagnostic scan can be performed on a vehicle using an OBD 2 (Onboard Diagnostics) scanner.
- It is usually under the dashboard where you can find the OBD port, so connect the scanner there.
- Inspect the ECU for the error codes that lead to the warning “Engine Failure Hazard”.
2. Consult with a Professional:
- Renault dealers and certified Renault specialists can provide you with assistance with your Renault.
- The error codes are analyzed by professionals with superior diagnostic equipment so that the exact problem can be determined.
- In addition, they are able to provide the correct information about the problem, the repair fee, and whether any other factors might also need to be replaced.
3. Address the Specific Issue:
- In the event that a repair or replacement is recommended by the professionals after the issue has been identified, follow those instructions.
- There are a variety of common issues, such as misguided oxygen sensors, malfunctioning thermostats, or problems with the cooling system.
4. Resetting the Warning Light:
- Using an OBD scanner, the error codes can be cleared and the warning light for “Engine Failure Hazard” can be reset after a necessary repair or replacement has been made.
- Depending on the motor, some may automatically turn off the warning light after the issue has been resolved, whereas others require manual intervention to be used.
5. Follow Manufacturer’s Guidelines:
- For specific instructions on resetting the warning light, consult your car’s owner’s manual or contact the manufacturer.
- Depending on your car, you may need to follow a specific sequence of steps in order to reset the light. In spite of the fact that the above steps provide a general guideline, the specifics are going to vary depending on the Renault model and year. To find out what instructions apply to your vehicle, check the owner’s manual.
