Seeing as I drive a 17 yo POS, I have no idea what the experience of getting a new car repaired is. Apparently many car companies demand that drivers only get their cars fixed through them. They do this by using computer codes that lock the mechanics of the car to anyone other than the dealer. This hinders the ability of smaller mechanics to make a living or provide alternate diagnosis. Ultimately it limits owners from having control over their own cars. What a scam.
From the Right to Repair site:
The need for Right to Repair legislation has become a necessity in order to protect the rights of car owners to decide where and how they have their vehicles serviced, whether at a new car dealer or an independent service facility. Right to Repair ensures that the person who bought the car and not the car company, can decide where that vehicle is repaired and maintained.
