Is anyone else experiencing frequent TPM Malfunction alerts? This is not a warning that your tires are low in air, but one that the TPM system has malfunctioned and isn't working. After 3 visits to the dealer to report this, among other problems, they finally discovered that my TPM antenna was bad and replaced it. During the same visit, they also determined that one wheel TPM transmitter was bad and replaced it. But since that service visit, I continue to get the warning. Is it likely that it's additional wheel transmitters that are bad? I really don't have time to go back again just for this problem. Besides the mechanics damage my vehicle in small ways (seats, handles, paint scratches, etc) on each visit.
