Default CEL after oil change

I purchased a 2005 Lexus ES last November. I had the first oil change done at a Lexus dealership with the 150,000 mile service. The CEL, VSC, Trac off light came on about 1 mile after leaving dealership, then went off on its own a day later. The lights never came back on until the 2nd oil change performed at Toyota dealership. Same situation as before, came on about half mile down road, stayed on a day, then went back off on its own. Car has 170000 miles on it, drives great, we even drove it from Ohio to Florida and back with no issues. Has anybody else experienced this? What could cause this? Surely 2x is not a coincidence.

It wasn’t related to the oil change.

I would *speculate* they plugged a diagnostic device into the harness to proactively look for business problems, and that was an after-effect. Just a guess.

You can scan the computer for trouble codes, other than that there is not much else to go on. Could simply be a coincidence or a low voltage coming from your alternator/battery.

Thank you for your replies. If it happens with the next oil change, I'll get the codes read.

Golddust8,

Not that this has anything to do with your problem, but it wouldn’t hurt at all to buy a new Genuine OEM Gas Cap for your Lexus. After removing the cap, clean the gas filler pipe where the big rubber washer in the cap seats itself. Also, spray a little silicone on the new gascap rubber washer before installing it to protect the washer from early aging and repeat this like every 6 months.

A bad gas cap will in fact cause these same lights to come on. Like I said, it probably isn’t “the problem”, but it will save a lot of wonderment if the gas cap seal goes bad like mine did. Buy the Genuine OEM cap because my aftermarket attempt with an Autozone recommendation did not work. $20 well spent.

Thank You. Yes, the lights came on after we purchased the car and I purchased a new gas cap, which took care of the problem until the oil changes. I've learned so much from this forum.

Old code is stored in the memory. You can look up what it was.
