I have a 2012 Camry base model and about a week after I baught it I started hearing a knocking sound when I start it. I did replace the serpentine belt and spark plugs and I still hear it. My mechanic said he can’t find anything wrong with it. Toyota put out a TSB in 2013 saying a camshaft timing sprocket was causing it. So I done research and my vin was covered under TSB BUT IS OUT OF WARRANTY. No recall has been put out and my car has 190,500 I’m just wondering if I need to fix that or don’t worry about it unless it gets louder.
TSB PIC ATTACHED
THANKS
Wow that sucks.... One thing you can try is to use premium gas. Higher octane helps combat knock.
Where did you buy the car? because whoever sold it had to know the engine was knocking and that's super messed up if they didn't disclose that. I would take it back to them and try to get your money back.
I can’t. Alabama the lemon law wont help me it was as is and the guy. Wont help me. I’m using shell 93 gas
