Another possibility is an exhaust system leak, particularly near the engine compartment, which can allow exhaust fumes to infiltrate the cabin. Clogged air filters may also disrupt the air-fuel mixture, resulting in a noticeable gas smell. Lastly, overfilling the gas tank can cause fuel to spill, creating an unpleasant odor inside the vehicle. For those inclined to DIY, it’s advisable to conduct a thorough inspection of these components, but remember that persistent issues should be addressed by a qualified mechanic to prevent potential hazards.
