What is your question?
When it's warm weather and when the a/c on my 2009 Buick Lacrosse will go into the Reduced Engine Power mode?
What makes this problem better or worse?
No, in hotter weather
How long has your 2009 Buick LaCrosse had this problem?
I've had the car for 5 yrs probably most of that
