    The battery is fine; the only time it goes dead is at an auto repair shop.....hmmmm. I have been reading about parasitic battery drains (I have OnStar and XM radio), but can't seem to figure out what technology the auto repair shops have that may be causing the battery drain.

Do a load test on battery may have a weak cell and is in of replacing they may have left radio and key on which was enough to drain what was left in the battery maybe only operating on 11.5 volts put on all accessories and rear defrost and see what the battery gauge does if it goes really high or if it stay normal or shows a low reading

Service Tire Monitor

You most likely will need dealer help on this, these older TPMS are not easy to calibrate, it requires a scanner. Next time you need to disconnect the battery use a small charger so the system remains powered up and you don't experience this kind of lost data problem

I have a 2004 sls seville and can't isolate a vibration problem.Had the tires replaced and balanced several timed and no luck. The vibration accure around 60-75 pmh.

First of all I would recommend getting Goodyear or Michelin Brand tires for the Cadillac or any other vehicles. I've had very good luck with these brands, as a technician for tires.

Secondly, I would make sure that the tires are inflated to the max. pressure recommended by the placard on the door.

Generally, 35 psi is the max. cold temperature. But, check to make sure it isn't higher for a heavy duty suspension model, if that's what you have. For instance, on my 1997 Cadillac Deville Limousine I have a spec. of 44 psi which is higher than the 35 psi I usually recommend for regular Cadillacs (say like my 1990 Cadillac Deville).

High speed vibrations can usually point to tire problems, as you probably already have suspected.

Good luck on making your Cadillac run like a dream.

My 1998 deville has a new battery, new alternator,oil changed and new filter and it sometimes goes dead as I am driving it. Oil light comes on. Have any ideas what this might be?

OK, the oil light going on means that the oil and filter should be changed again and the 10w30 oil should be used.

The alternator may be defective.

2004 Cadillac Deville Check oil light is on...........

You need a new oil pressure sender switch. I have had to replace mine also. Not too expensive (15.00) but tough to get to.
