Problems with 2003 Mitsubishi Outlander EQUIPMENT

Tl*the contact owns a 2003 mitsubishi outlander. on two different occasions, the tires flattened due to the valve stems. three of the valve stems were repaired at $20 each, and the first valve stem was free. nhtsa campaign id number 08t018000 (tires:valve) was referenced. the failure mileage and vin were unknown.

When car was first purchased told dealer it felt like back end was kickin out on wet roads,took it dealer was told they could find nothing. several days later car spun out on way to work due to blow out. had vehicle towed to dealer were upper and lower lats. were replaced.(no old parts not available) car seemed ok for several months at which point it began to feel like it was sliding around in rear end again. again dealer checked found nothing.. my husband threw a fit with dealer at which point a ball joint was replaced(part not available), in my opinion only to pacify us. the car has still never felt right. at which point the warranty has expired and the dealership refuses to even talk to us about this. now four months after having four new tires mounted and balanced i have two rear tires so worn and damaged the belts are coming through them. i have taken the car to a private tech.to try to find anything that may be wrong. i am scared for myself and my family everytime i have to drive this car! *tr

This is a 2 year old car and the heater and air conditioner do not work. i have ra and lupus and my husband has emphysema. the lack of air conditioning makes it hard for him to breath when it is really hot, and the cold really hurts my joints. the air broke just a couple of months after we bought it, we took it back to the dealer and they said it was not covered under the warranty, we bought the extended warranty. then a month ago the heater stopped working, we again took it to the dealer and they said it was not covered by the warranty because it is a defective heater,so there for it is not covered, i do not know why i purchased a warranty if it does not cover defective equipment. my husband and i are both disabled and on a fixed income which is why we purchased the extended warranty, we can not afford to fix it can you help. *nm
