I guess it's time to return to the dealer...at 6800 miles:

The TPMS reminds me to Check Tire Pressure every time I start the car...the DIC states my tire pressures are 24 PSI. I've checked...all the tires are inflated to 32 psi. I wonder what causes that?

The driver's door glass AUTO UP switch isn't. I wonder why not?

Oh, and the OLM states 10% oil life remaining. Wow, I would have normally changed the oil twice by now.

I hope the service department can get everything fixed in one day.

Thanks for responding.

The TPMS started acting up last week when I backed out of the garage with temp at -7 degrees. The OEM tires are at 32 psi (checked with my super duper gauge from my racecar days and a cheap stick-type pocket gauge)

Even though the battery has never been disconnected or discharged., I tried the reprogramming technique posted by Sparks...no change.

I've trusted the OLM since my 1st GM vehicle that was equipped with the system. I figure the folks that designed and implemented it are lots smarter than me. If GM's system says the oil life is good for 7000 miles, they must have confidence that warranty claims due to extended oil changes won't come back to kick them in the arse. My Duramax equipped truck has, on occasion, made it to 10K ...even with towing my 13K lb 5th wheel around the country. My Malibu is a "city car" and rarely sees the highway. I check the dipsticks regularly...and haven't had to add a drop of oil to either vehicle between oil changes.

I'll get to the dealer next week...the weather is too nice this week so I'm playing golf!

Well, I “learned” a couple of things today.

From the mouth of the circus advisor: “Your tires were underinflated. They were set to 32 psi. That’s not enough pressure for a 17” tire. The sidewall states max pressure to be 40 psi…you have to inflate them to at least 35 psi before the TPMS warning shuts off.”

When I pointed out the manufacturers tire placard states the tires should be inflated to 30 psi COLD, he said: “Well, I don’t understand why they put that low of a number on the sticker. You’ll get better tire wear and gas mileage if you run them higher. That sticker doesn’t make any sense to me.”

When I started the car, the TPMS warning was off but, the pressure readings on the DIC indicated that the pressures were now 27 to 28 psi…not the 35 psi that he reported the technician had set. His response: “Those sensors aren’t all that accurate. You’ll have to keep the tires up to keep the warning light off.”

The repair order stated that the “Express Up’ feature for the LF door glass was NPF…No Problem Found. I guess that means the technician determined that my car is not equipped with the express feature that worked for the first 5 months of ownership???

I suppose I’ll be a bit less tolerant when I take the car back tomorrow. I didn’t feel like arguing…Never argue with an idiot. They bring you down to their level and beat you with experience.
