Consumer Description

The car experienced issues with the fan turning off when car was turned off. It caused the battery to die. The car was serviced at the dealership and the tech found that the fuse block overheated and melted, causing poor electrical connections. They replaced the damaged parts and repaired the wiring. This still did not explain the fan not turning off and after the fuse block repair, the cooling fan was still sticking on. After pushing the dealership to further look into the issue the mechanic determined the issue was inside the fan assembly (it was assembled in the wrong direction), so they replaced the cooling fan. The dealership stated that this was a manufacturing error. They said this could have caused an engine fire and there was absolutely no warnings - just a fan that was stuck on. This could have put me and my new baby at risk for an engine fire and could cause issue for other owners if there were more assembly errors. The car is available for inspection if needed. It was only inspected by technicians at the dealership.
