I have owned this Neon for about 3 months, and so far the service engine light came on about 1 month after getting it, but it soon went off, well then my horn stops working soon after that.
The next thing you know, reverse goes out on my car, and it drives in neutral, so I call a service shop, and they tell me that this is very common in these types of car, and that it is either my transmission or just the shifting linkage. I am hoping for the linkage, even though it is still under warranty. I still don't want to have to wait for a new tranny to be dropped in it.
Also, ever since getting the car, I have noticed a popping sound in the steering column whenever I go over a bump or turn sharply. I have no clue what this could be, but other than these problems, the car is nice and fast for the price.
