We bought the CX5 new when it was first launched in Canada. From time to time, seemingly random alerts pop up from the TPMS. On our model it is the one where there are no specific wheel sensors. The problems happen on summer or winter wheels and tires. When checked there was no appreciable difference between pressures.
My wife is the main driver, so I would just take her report, check that the pressures were about right, and reset it.
I discovered on our car, as described in the manual, we need to set the parking (emergency) brake for the reset to work. Otherwise it just seems to clear the dash light and it would come back on again once the car was driven. As long as I reset it properly, the alert did not come up for another few weeks. I thought there was a "monthly" maintenance warning that could be triggered and the service department could turn it off. However, our local guys said "not on the models sold in Canada apparently".
When riding in it together, the alert triggered and my wife said - "It almost always goes off around here". I stopped and reset it and looked around. There were several antenna masts with microwave repeaters on them.
I know many years ago with my Mazda 6 sitting in the telco's microwave beam would disable the alarm system, forcing a reset before it could be armed or disarmed, and I wondered whether someone these devices could somehow interfere with the TPMS monitoring. Thinking back, my wife was fairly sure that she has not had it trigger falsely anywhere else in our area.
So, my questions are ...
Based on their understanding of the TPMS system can anyone imagine how that could occur?
Has anyone else had spurious TPMS alerts that might tend to repeat in the same general vicinity such that they could be a similar issue?
Thanks for any thoughts. I have fashioned a hat from aluminium foil just in case!
