    All of the recalls have been done, no new engine just updated knock sensor software, new hybrid battery last year.

    About 3 weeks ago it went into limp mode and we were told by the hybrid tech at the dealer that it needed new spark plugs. So to the tune of $600 they replaced them. All was fine until last week when driving the Check Hybrid System - Do Not Drive warning came on. Turned it off, waited a few seconds, turned it back on, and the check engine light was on but I could drive it. Drove it again a few days later and left it running while parked and waiting on someone and the hybrid system light came on again. Same result after restarting, just the check engine light but it will run fine.

    Has anyone else had this happen? I am ready to sell it, I have zero confidence in it anymore.
