background to question:
Recently I ran into opposition to a suggestion I made that gm should improve aspects of its tpms so that it would be more hassle free. This was prompted by my own experience:
- apparently the dealer provided the vehicle to me without it having been checked to verify if the tires had been registered properly (or whatever the process is called).
- this didn't really come out until it became clear that I had a tire with an issue, but it was displaying at the wrong position on the dashboard, and I was struggling at gas stations to verify which tire to fill.
- In the end, I checked with the dealer twice, and it does appear that many of the dealer visits that folks have to them have to do with tire pressure.
- However, it's not clear from what little I was told that this is because there is something wrong with the system. In some (or possibly many) cases this may be because increased awareness of tire pressure being off may lead to customers simply wanting the dealer to bring the tire pressure into line.
- I can't remember from my Leaf experience 2012-2015: are there many or any situations where Leaf tire pressure presents for the the wrong location of the tire? also, are there many situations where a mechanic will forget (or not have the right tool to hand) and the pressure of multiple tires will be incorrect on the dash?
- Do other vehicles (whether or electric or otherwise) have this issue?
- is it inherently expensive and difficult to clear this up in designing a tire pressure monitoring system?
What I am getting at is that in my view anything that leads to a lot of dealer visits to me constitutes hassling the customer, whether from the neglect of a mechanic on a simple task, or from something else. So, I suggest that if there is a way to revise tire pressure monitoring so that it is less prone to reporting incorrect numbers/locations, for whatever reason, that this be done. However, I don't know if there is something inherently expensive to the matter (one person has suggested this) or if it is just a matter of approaching the matter differently from an engineering/design standpoint and it can be addressed without that much difficulty.
