Dec 10, 2024Power train I had an issue with the AWD not engaging and the 4x4 light illuminating when driving on snow and ice. No indicators when driving under normal conditions.

Apr 21, 2023Engine Driving kids to school a few months ago. Car started to smell like burning rubber. I thought it was the garbage truck ahead of us. As we turned the corner 2 blocks later, the car dead stopped and we all went flying forward. It jerked so hard, we are lucky our necks didn't snap. I put the car in park and turned it off. I waited a few minutes as I was too worked up, and started the car again. We got about 50ft before a very loud noise began, almost as if something was dragging underneath. I stopped, and had it towed home. I then had it towed to mechanic. They said bad TRANSFER CASE & DRIVE SHAFT. - TRANS PAN GASKET. I am a single mom with no money to afford to have it fixed in fear of it…
