Is It Normal for a Sedan's Trunk to Get Hot?
2 Answers
It is a normal phenomenon, likely due to the heat dissipation from the exhaust pipe. Below is some information about the car trunk: Overview: The trunk can be opened or closed either electrically or via remote control. To open the trunk, simply press the button inside the car or on the remote key, and the trunk will open automatically. Precautions: Do not place flammable or explosive items in the trunk. Since the trunk is an enclosed space, the temperature can rise very quickly. If items like lighters or hairspray are stored in the trunk, the combination of summer heat and long-distance travel can easily lead to explosions, with unimaginable consequences.
Last time I took my family camping by car, I touched the outside of the trunk when we got back and found it scalding hot. I immediately asked a mechanic. He said the car's exhaust pipe runs right under the trunk, and it's normal for metal to conduct heat after long drives, especially in summer when the road surface gets extremely hot. But if the inside of the trunk also feels hot, or if the spare tire compartment feels abnormally high in temperature, it might indicate damaged exhaust pipe insulation and needs inspection. I once encountered an even more extreme case where a friend's hot water bottle leaked in the car, melting plastic parts. Now I've developed the habit of checking spare tire temperature to prevent potential hazards.
