I was offered unlimited oil changes for the duration of my contract. Apparently, unlimited is limited to one oil change every 8000kms. Bumper to bumper coverage did not cover numerous items found between those bumpers, including the cv axle joint. Additionally, the payments they tried to offer me far exceeded the agreed upon price. Dealerships are con artists that employ fast talking finance officers to recoup the money they "lose" from desperate salespeople. Don't pretend they're not.

People invalidate contracts all the time. There's nothing you can do about it either unless you're willing to spend months battling in court. In the meantime your car needs to be repaired so you can go to work. They know only a small percentage of people will take the time and effort to battle them in court, so overall denying claims is economically efficient.

As a side note: NEVER buy an extended warranty from a car dealer. It's always a scam. If you buy one and something goes wrong they will try everything in the book to avoid covering it, and 9 times out of 10 you won't need it as long as you aren't buying from a shit car company.

Ask the salesperson why they're telling you how unreliable the car is in the middle of trying to sell it to you. Sometimes it's fun to get the sales manager and ask them why they let this guy be a salesman when he's sitting here telling customers how the cars are going to break down on them. It's like watching Jen Psaki explain "Putin's price increases."
