Q: my 2008 toyota camry hybrid has the check hybrid system light on but still runs properly. Intermittently it will stop responding m

To begin, first my power steering was acting up. We replaced the power steering module and everything ran fine for a month or so. Then the vehicle began to act up intermittently, displaying every dash light possible, the a/c would go from cold to hot air, and the vehicle would not allow me to accelerate. It seems to me like an electrical issue but I have no clue where to start. To add to that, when I had a mechanic run codes, every single code possible comes up so there is no telling where to begin. What is even weirder is, after shutting the car off and waiting, the lights will go away and the car will drive just fine only to come back again later. The temperature outside seems to be a factor in its malfunctioning, the heat causes it to occur more.

Thank you for any Insight -Alec
