Car sometimes has a hard downshift from 2nd to 1st and a hard up shift from 1st to 2nd. It makes a clunk noise and causes to car to jerk and or lunge. I see many complaints on the internet for this issue and I think I was sold this auto without disclosure of an known issue.

I have a hesitation/lack-of-acceleration when moving from a stop or from low speeds. Essentially, I'm either moving very slowly or I have to floor the gas pedal to force the transmission to change gears, and then the car 'takes off'. there is no middle ground (I.e. I can't simply accelerate 'normally'). it is dangerous when merging on to a highway or out of a driveway or shopping center and onto a busy road.

My brand new 2010 Audi Q5 exhibited two dangerous transmission related problems within the first couple weeks of ownership in January 2010. Both issues were intermittent and unpredictable. First, upon slowing to a stop, just prior to complete stop the car would suddenly surge forward on its own with almost enough force to overpower breaking if you didn't react quickly by applying more break pressure. Secondly, the car would experience a lag in engaging gears when attempting to accelerate from a stop or near stop. My wife almost got in an accident with oncoming traffic while initiating a left turn at a busy traffic intersection because she applied the gas pedal and the car merely idled forward into oncoming traffic. After a long lag the gears engaged and the car accelrated just in time to clear the intersection before getting hit. My wife and I each separately and together experienced both issues multiple occasions. We brought the Q5 back to santa monica Audi. They took a look and found that a transmission valve and filter were "obviously installed incorrectly at the factory". both parts needed replacement. They did the work between Jan. 11 - Jan. 25 2010. I only had the car back for 24 hours before noticing the same issues again. I brought it back to them on Jan. 26th. The car is at this time still at the dealership and an Audi engineer from Audi of America is on his way to take a look at it this week. I have been in communication with at least 5 other Q5 owners who have experienced similar transmission issues to varying degrees. Something should be done about this before it causes a major accident.
