- Unusual smells, such as burning coolant
If you notice any of these signs, it’s crucial to stop driving immediately to prevent catastrophic engine damage.
Transmission Issues
While the engine is at the heart of the vehicle, transmission problems can also manifest as engine-related symptoms. Owners may notice:
- Delayed shifting or slipping gears
- Unusual sounds during gear changes
These issues can often be mistaken for engine problems, but they can significantly impact overall vehicle performance.
Electrical System Symptoms
Lastly, electrical issues can also affect engine performance. Symptoms include:
- Difficulty starting the engine
