11 years of ownership, 145k miles, clean and reliable car. The engine and trans are rock solid as far as I can tell, but here is what I am getting now... Chirping noise while driving or idling, it doesn't matter, every 7-10 seconds. It used to be only while opening the door or braking. Sounds like the brake actuator might be the culprit. I got the CEL after changing the 12V battery in May. Stopped by AutoZone to get it checked. P1121- the 3 way coolant valve might be the one to replace? C1241- not sure about this one... These codes aren't really related to a brake actuator issue.. Also the hybrid battery is on the edge too. Overall, I am looking at the hefty bill here. Drive it, sell it or fix it? I am looking forward to fixing it.
Only owned ours for a year and it does the same. Previous owner said it had done that for years. Keep it. Too many good things about these cars to outweigh your few issues.
'09 is a beast, just broken in at 145k. i'd do whatever it takes, even if i didn't want it, it's worth a fortune on the market in decent condition.
