white trunk open light comes on when the trunk is closed

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your vehicle. If your E350's trunk open light stays on even when the trunk is closed, it could be due to a misaligned trunk latch or a damaged trunk sensor caused by slamming the trunk shut with the tire inside. The force might have jarred the latch, misaligned the mechanism, or damaged the sensor, making it read as open even when closed. Try gently pressing on the trunk lid to ensure it's fully latched. If that doesn't help, you may need to adjust or replace the latch or sensor. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
