2010 RX350. Approximately 88000 miles on it. Lately I noticed that the AC is relatively weak - it blows luke warm air after I get in the car. This happens even I drove the car and starting it after a 2-3 hour break. The AC starts to kick in/get colder after approximately 10-15 minutes. I don't recall the car behaving that way before. Is this normal? I had an early 90k miles maintenance done on it about 4 months ago.

Thank you!

It may just need a refrigerant top-up. Then again, there may be a leak in the system that you will need to address.

Unless you complained about an A/C problem they would not have checked it during the maintenance.

+2 Seems like all my cars lose about 1 oz refrigerant per year, and once they are down 8-10 oz, that is what happens...
