I have recently gotten a few warnings on my '06 CTT. First one was a flat tire warning, checked tires air pressure etc. everything ok. Next one was a light out somewhere didn't say where checked all bulbs all working ok. Finally I got a warning brake pad workshop, I just had the PIG in the shop and had the brakes checked I had plenty of pad left. All of the warnings went away when I shut off the engine and restarted it. If there were a problem would the warnings go off like that ? I did not get the warnings all at once but over a few days. Could it possibly be the battery it is the original . I have 35,000 miles and the brake pads were changed at 19,000 miles . Any ideas would be appreciated.
Thanks

 

Has there been any slow starting??? I would have someone put a tester on the batt and check it and the alt.
