I have been lucky, I have a 2008 Chev impala LT with 220 km/139mi....mileage. Suddenly in Jan. 2024, one actuator (the recirculating air - fresh or inside recirculation actuator) starting clicking and then 6 months later July. 2024, the 2nd actuator ( the left side glove box actuator for the temperature of the passenger side starting clicking). I have read, virtually every owner of a Chev Impala has had to change these actuators sometimes over & over again. The Chev dealers overcharge to change these actuators, cost to change the actuator and labour at a GM dealer has been reported to be $1000+. This was a faulty designed part originally installed in the vehicle. The Chev Impala otherwise is a well built vehicle, so many Impalas still on the road while the equivalent 2008 Fords & Chryslers are all in the scrap yard......I believe most of these Chev Impala sedans were built in Oshawa, Ontario, Canada.
