Fast foward two months later. We are on a trip to visit some friends six hours from home for the weekend. We get ready to go somewhere, get in to start the van and it is dead. It does the same exact thing it did the first time, acts like it's going to start, sputters and dies.
We are now six hours away from home, stranded at our friend's house. We had gotten there Thursday and were supposed to leave early Saturday morning. We call the local carmax there, because even though the carmax 30 day warranty is over, we purchased an extended warranty. This happens on Friday around six. The local carmax says they are closing, but since it is a Mercury, we can have it towed to the mercury dealership and our warranty will be covered. On the phone, the promise me that it will be no problem with the warranty.
We have it towed there, and Saturday morning, the guy from the Mercury dealership calls. He says that the whole camshaft system is bad, and that is what is causing the sensor to go bad. He doesn't know how Carmax could have missed it the first time. He told us in so many words that he suspected because it broke while it was still free to get it repaired, they did the minimum amount of work.
He then says the can have it fixed that same day, except that he has to get the warranty approved, and they are closed on Saturday.
There isn't even an emergency number. I guess carmax doesn't think that people can have vehicle emergencies on the weekends.
We ended up having to pay about 160 dollars including towing.
We are currently battling them to get our money back, since they should have fixed it the first time.
