2025 Porsche Macan Electric 4S — runs hotter sitting in traffic than moving

RotorGalCommunity StarterMay 21, 20262025 Porsche Macan Electric 4SSouth Florida

2025 Porsche Macan Electric 4S, about 14,500 miles. Coolant temp climbs while idling with the A/C on, then drops back down once I'm moving. Coolant is full and I don't see a leak. Fans do run, but I'm not sure they're moving enough air. What would you test next? If I fix it I'll come back and update the thread.

Intermittent stuff lies if you only catch it once. Two 2025 Porsche Macans can feel identical and have different causes, so measure before you copy someone else's repair. Don't erase codes until someone who can help has seen them. On “runs hotter sitting in traffic than moving,” that was the fork that mattered for me. This is from a 2025 Porsche Macan in South Florida with 14,500 miles. Parts cannon is a personality type I try to avoid. If the story changes I'll post the new data.

There is early surface rust on brackets, fasteners and seams underneath, but nothing structural. For a salt-belt car, what treatment slows it down without creating a hard coating that traps moisture?
