“Anytime I turn the air on in my 2005 chevy avalanche it makes a high pitch screaming sound. I have had two blower motors installed and it is in need of a third. This sound is still present even after I have had the new motors installed. I have had one mechanic say their is a crack in the plenum box and it would take 11 1/2 hours to repair and cost $ 1700. This is the only quote I have had so far. I have had it at the dealership where I bought it and they never seem to find anything, then again they seldom do anything right.”
NHTSA complaint #10390156, filed 2011-03, 36,500 miles“Traveling home from work on the interstate at regulated speed (65mph). As I started to accelerate to maintain speed gingo up a hill, the message transmission hot came on the in-dash display and engine began revving as if not in gear. I could not accelerate and had to turn on flashers and merge to safety lane on right. I continued to slow down until I could engage the transmission again at around 30 MPH in 3rd gear. As soon as I started to accelerate past 35-40 MPH, the transmission slipped again and would not engage any gear. …”
