High idle during high ambient temperatures. Idle is raised to 1000-1050rpms during temperatures above 90F. This causes loading of the transmission and additional brake pressure is needed to keep the car at a stop. This can occur suddenly and randomly presenting a safety issue. I have almost ran into several cars at various times when stopped at a light or in traffic. It has happened countless times during the high ambient temperatures.

ABS brakes have been pumping without inclement weather. It pumps randomly at any speed and any weather. Nothing has been resolved from the dealer. The brakes also make excessive noise, grinding or metal to metal type of sounds or contact. In addition, multiple electrical or malfunctions within the year I have owned the car- only 9491 miles. A. air bag light went on and stayed on until I brought it to the dealer. B. the driver sun visor shorted and was inoperative. C. ignition was weak and would not start after several times. Car would die. Brought the car to the dealer, no resolve. The computer could not duplicate problem. Finally as I am driving the other day, a malfunciton light appears and the car dies. I had the car towed to the dealer. D. after 5,000 miles check up, the service light appeared and stayed on until I brought it into the dealer to turn off. E. at this time, the car is in the dealer. They found that the ignition switch faulty and will be replacing it.

I purchased my VW 3.6 4motion Passat with 71 miles. When the vehicle reached 200 to 250 miles, the engine started shaking when gently applying brakes at slow speeds. I also experience this when the gear is in drive and their is no gas being applied. I have serviced the vehicle with Volkswagen twice and they state that this is normal behavior. I have researched this through a internet forum and discovered that not all owners of the same vehicle type that I have experience this symptom. The shaking topic can be found at the following url. forums.vwvortex.com/zerothread?id=2619540.

Purchase 2006 Passat with 4 wheel motion in Feb 2006. Approximately 6 weeks later engine light came on. Took to dealership where they took out the gas tank to repair vacuum problem. Then there was groaning when I turn the wheel left and right. Took to the dealer and they replaced brake parts. It is now three weeks later and I still have brake problem. The car now groans when ever I turn right, left or straight. Especially loud in stop and go traffic. I fear that the brake system is unsafe. Dealership showing no concern. I am on my second attempt to fix the brake. I will contact a lemon law lawyer if this fails.
