Of the many problems I've had since purchasing this vehicle, the latest takes the cake. Here's the skinny of all my problems, with the latest motivating me to report a complaint to the NHTSA. Hopefully, something can be done. Here's a website of others with the same transmission issue: www.carsurvey.org/cgi-bin/fix_comment.pl where do I start. I purchased this car with 38K miles and it's been a nightmare. First thing to go was a wheel bearing at 41K, got that fixed @ $200. Next to go @ 48K was the two calipers and new rotors on the front, cost $800. Next @ 52K was the A/C needed to be recharged, $150. Next @ 58K, the two calipers in the back has to be replaced, cost $300 (I found a good mechanic/friend). For the grand finale... I need to replace the transmission @ 61K, cost range from $1,800 to $3,400. I will fix it and dump it right away and sell it. A complete lemon!!! it should be reported to the NHTSA for an investigation.

Sudden flow of very hot air form the air vents. The problem happened when the air condition was off and the air blower or fan was turned on. However the problem now happens when the air condition is on.
