Wiring problems of the 2011 Hyundai Elantra

The windshield wipers flew off of my car during a rain storm while I was driving. I was told by the place that repaired it that the dealership didn't fasten them on correctly. When I took my car in for an oil change the service technician said he fixed my recall as well - the car never had a recall repair notice ! air conditioner does not work - when service did oil change they tried to tell me it was going to be 415 dollars to fix the air because the discharge hose is leaking. The discharge hose costs 11. 00 on the internet & valvolene instant oil change will refill the freon in your car for less than 140 dollars. The brake lights all have needed replaced consistently every other month - I'm wondering if there is some kind of short in the wiring?.

On 6/27/2011 the car was hard to start then shut off as it was backed out of a parking space. The car would not start for twenty minutes. The dealer test drove the car after it was towed to them and the car almost stalled at highway speed. The dealer could not identify a problem (no error codes) and decided to change the fuel pump. On 7/8/2011 the car shut off while driving through a parking lot and would not restart. The car was towed back to the dealer and after several weeks the dealer thinks the wiring harness and computer are to blame. The dealer has not located a new computer or harness as of 8/01/2011. This Elantra also has had five incidences with the transmission locking in either drive or park. We were told to just stick a screw driver in the front of the transmission console and hit the reset switch. The dealer has made one failed attempt to fix the problem by replacing a brake light switch. The dealer has since replaced the brake light switch for the second time, not sure if it fixed the problem. We only had the car back for a short time.
