Has anyone else had to have the three timing chains replaced? I had 32K on the car and a CEL came on. They diagnosed it as a timing chain problem qnd replaced all of them. Today (with 42K) the CEL came on and the car was running rough. I take it in on Wed and will post the outcome. Just hope this isn't some indication that the engines (09 3.4) have a weak area. Thanks

 

I said I'd post the outcome and here it is. The code checked out as a misfire. They test drove it with the test equipment hooked up and it went away. I'll be watching it closely.
