Chevrolet

This a copy of an email that i sent to Mr. Lewis Cook the General Manager of Martin Chevrolet, and never got a response. I also sent Ben Guetterman a similar email that he also never responded to.
Mr. Cook,
I am sending you this Email because of my experience I had during my last visit (06/03/2019) and it also means that Ben Guetterman has not responded back to the last email that I sent to him. I had a bad tire sensor and asked to have it repaired while they were doing the oil & filter change. I was informed about an hour later from my service advisor Alvin Sumera that the other 3 sensors were not responding now after they put it into learning mode, and that they would also need to be replaced at an estimated cost of $190.00 each or $760.00 total! I said that I would not be replacing any of them, and then I started to ask him a question and he cut me short, and said I'll let you know when it's done and did it again when I started to speak again!. So the truck came in with 3 sensors working and now none of them work the spots where the pressure would be are blank. I was told that's just the way it is (REALLY).
So I got hold of Ben Guetterman the service manager the next day and he asked if I could bring it back to have his Master Tech. look at it. So I left work a couple of hours early, and had it looked at. Well if I had known that he was only going to try to reset the sensors using a hand held TPMS monitor I would not have wasted my time, because I had already done that at work in the morning. I thought that maybe he was going to go flash the computer system or do something different.
So while the Tech is trying to explain to me all the possible reasons that the other 3 went bad at the same time with reasons like the batteries are low, after market wheels, and weak signals because the sensors are farther in than in the stock wheels. So as the Tech is explaining to me about how some of or all the rest of the sensors can go bad while it's in learning mode I tell him I understand that but all 3 at the same time. I also told him I know the other 3 were working because I just rotated my tires and had to adjust the pressure from front to rear and it showed on the screen with no problem. I don't think the batteries went dead in 3 years the average life span is 5-7 years. While these may be legitimate reasons the fact of the matter is I came in to have repairs done and left with more problems than I started with, and a huge expense to repair the problem, and they all say oh well that can happen !
So this experience turned out to be a total waste of my time and use of a couple of hours of vacation time. This could have been avoided if the service advisor had warned me that this could happen, but it was never brought up, and now none of my sensors work. I would have rather had 3 of them working than none of them.
This truck is 3.5 years old with 26K miles on it. If these sensors are only going to last this long than GM has a problem on their hands. This is the only vehicle that has ever given me any problems with tire sensors. My wife had an Acura MDX that was 10 years old with aftermarket wheels and over 100K on it and never had a sensor go bad along with both my Toyota Tundra & Tacoma.
I look forward to hearing from you on this matter. You can Email me at [protected]@sbcglobal.net
