I've never had them because of any noticeable issues, or warnings (accept for tpms), but I do just run my scanner on occasion. If it didn't illuminate a warning light, I would suspect it was just a computer glitch. If you've been driving it since the scan, maybe do another scan to see if it has returned. These cars are notorious for computer issues if your battery is weak. Maybe have a battery load test done. Most auto parts stores do them for free.</p></blockquote><p></p>
