I ran into this problem and wondered if anyone else has hit it too:
Had 4 new tires put on my 2005 Outback wagon, LLBean model so it has the tire pressure monitors on each wheel. Tire dealer was very specific about having appropriate equipment and training to deal with the TPMs so it seemed like it would be easy. Picked up the car and drove for 1/2 hour - TPM light came on. Took it back to tire dealer - no light, no problem. Finally took it back with the light on and they called me in to the owner's office to explain the problem.
Seems that their equipment for TPM (Schraeder) was sold as being able to deal with any cars with TPM. However, they've just found out that Subaru (and Nisson, maybe Toyota) use proprietary equipment, not available outside the dealership. So I now have to go to the Subaru dealer to get the TPM system set correctly - at a cost of $18. Subaru delaer confirmed it and provided the price.
So - despite buying tires at a place that provides free rotations for life, I have to take the car to the dealer following each rotation to get the TPMs reset. An interesting situation, since it's technically illegal for the tire dealer to release the car with the system malfunctioning. The only way to avoid this is to have all tire work done at a Subaru dealer!
Starting in 2007, all cars must have TPMs and at least in NY, a functioning TPM system becomes part of the inspection. It seems like something is wrong here, but the only person to suffer is the consumer.
Are there any other options to get around this?
