I have a 2021 CX-5 GT-R, 22,000 miles. My wife has been complaining that it takes too long for the passenger seat to warm up when the seat heater is turned on, even on high. So today i finally checked it out. The drivers seat seems to heat up to where it is noticeable in about 30 seconds but the passenger seat takes over a minute longer before heat is detected. Does anyone else notice this? The dealer said to bring it in next week and they would look at it but would like to have a feeling if this is common before they start tearing into the seats.
