Hi. I have a 2012 Honda CRV that I bought two years ago. The air pressure light keeps coming on, no matter what time of year. The tires are all basically new. I've had it to the garage recently to check for tire leaks and they couldn't find anything. Every time it gets below freezing outside, a tire(s) loses air and the warning light comes on. I then have to add more air. I called the garage, and they said this is normal when it gets cold; but it happens all the time. The mechanic also said every tire and car is different, and some need air every week. My husband has a new Hyundai and never has issues. I talked to one person who used to work in auto sales, and he says this doesn't sound right and to have the seals and valve stems checked. Thoughts?
