ICV recall work recently completed in 2005 Sorento. Serious damage to engine due to ICV, Sorento towed to dealership. 8 days in shop to repair due to back log at dealership. While in shop also agreed to have serpentine and timing belt changed, transmission fluid changed, spark plugs replaced and oil change. 8 day car rental and $450 later car was ready for pick up. Morning after pick up from service and ever since at start up there is a ticking noise that lasts for first few miles driven then stops. This noise never occured prior to the morning after picking up. Went back to dealership where car was fixed but of course the noise was not recreated because the car was already warmed up. Aprox 5 days after getting car back the battery died. Just recently the AC stopped cranking out cold air. This was all of a sudden, after a 1.5 hr drive with the ac working great it just started blowing warm air. There was no gradual temp increase. I was told by the service manager to bring my car in and leave it over night so that the ticking noise can be heard, since it only happens when the car is started once cooled. While I plan to do this it's just a matter of when I can, already had to rent a car for 8 days. I have a couple questions - Could this ticking noise be some further damage caused by the ICV clip, something they missed when doing the engine repairs? (2) could replacement of either of the belts cause my battery to die and my AC suddenly stop blowing cold air?
