Buick Enclave engine won't shut off. Parking brake light comes on when not, leak near glove box.
I bought my new Enclave brand new and with the exception of an issue with the air conditioner a year ago have been a happy, happy customer. About a month and a half ago when there was a heavy rain storm I noticed that every time I'd stop to go into a store and reenter my car the parking brake light would light up and I'd receive a screeching beep, beep, beep. In order to correct it, I'd push down on the parking break, release it and go on. Next store the same thing. Once I was home and drove the car the next day. There was no problem at all. I noticed a mildewy aroma in the car with in the next few days, but figured it was due to me getting in and out in the rain. Fast forward a month and there is another heavy rain storm. I'm driving on the highway and the screeching beep, beep, beep goes off again with the parking brake light coming on. It would come off if I left the road, put the car in park, and reset and released the brake. It was very annoying, and since I was near the dealer, I took it in. They hooked it up and could find nothing wrong with it on the computer. Now today 1 1/2 weeks later there was another heavy rain. When I arrived at my destination, I put the car in park, turned it off, took out the key, and the car kept running. When I tried to leave the car again I'm hit with a beep, beep, beep...this time with no parking brake light but the little yellow engine light was on. When I tried to drive home, I lost power and limped at around 30-40 mph but eventually the engine kicked in. As I was almost home, I noticed water streaming out near the glove box. Anyway, I've rambled enough. I called the dealer, but of course service is closed today. I'm hoping that with the window rolled down and the hood up that the car will dry out and I'll be able to drive it...although when I just started it up a few hours later, it still would not shut off but ran for about 5 minutes before it acted like it was out of gas and finally shook until it stopped. Oh, and I almost forgot. The little yellow light is still on even when the car is off, and there is a high piercing noise. Help!
