“While driving on a very populated interstate may car lost power and was stuck in one gear and I nearly got hit from behind by another vehicle. Mercedes told me that my conductor plate failed and this was the cause of my transmission slipping from one gear to a very low gear. In my opinion this is very dangerous for our roads and I think that they should be responsible and make this problem go away before someone or multiple people get hurt.”

“Takata recall-I took my vehicle into park place mercedes of arlington in dallas, tx to get a diagnostic on why my panoramic sunroof would not open. I thought it could be repaired but service tech told me that the whole roof would have to be replaced. I feel like these cars are too expensive for parts not to be able to be repaired and have to be replaced.

“Takata recall- I took my vehicle into park place mercedes arlington in dallas, tx to get a diagnostic on my comand unit radio. The cd/dvd player would read the name of the disc but would not play it. An error message comes on that says disc error. I figured something on the inside may be dirty and just needs to be clean as the discs were readable by the comand unit. The service tech said that the whole unit needs to be replaced and they can't repair it. $1800 for the repair on the same exact unit. An outdated unit that doesn't even have the newest technology. …”
