general problems of the 1998 Oldsmobile Silhouette

The contact owns a 1998 Oldsmobile Silhouette. The vehicle has toyo 800 ultra tires. While driving between 70-72 mph, both front tires and one rear tire flattened on three different occasions. Prior to the failures, the contact felt a vibration in the steering column. The vehicle felt as though it was driving unevenly. The tires flattened instantly. The fourth tire has cracks in it and is about to fail like the others. The tires had 20,000 miles and 75% proration remaining. The contact has pictures available. The failure mileage was 100,000.

I've had brakes fixed, and have replaced the tires twice! the back-end keeps making noise every time you change the gear from park to drive or any other gear. The brakes squeal a lot and the back end seems like it wants to come off, very loud and very loud squealing. Would not recommend anyone to buy this type of vehicle and I won't buy another one! car has had these problems since purchased new in 1998, but under a 5 year lease, I feel stuck! very dissatisfied customer!.
