2015 LT1 - Check Engine light comes on intermittently. Has been off since mid May, came on yesterday. Went off briefly today, back on now. It has been doing this for almost 18 months, dealer finds nothing, says only code is 'generic'. In other words nothing specific. Usually by the time I can get it into the dealer the light has gone out. Thoughts? Light stays on for 3-5 days, then goes off.
