Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
First it was the broken blinker, then I got nails in 3 of my run right tires, my tire gauge light is NEVER dependable, my coolant light comes on and off for no reason, and now there is an awful smell coming from the air conditioner.....the dealership has very poor customer servive. I feel like I should have some options here. Can anyone let me know what to do?

Try an other MB dealer in your area with a better customer service. If no help from the dealership, call MB of North America and ask them for help or complain to them.
Their contact info is in your owner's manual.
If they won't resolve your problems, try BBB (Better Business Bureau).
