| Re: Knocking sound
My scenario is described perfectly in that entry as it doe not fail over 60 degrees of so, and believe it or not, it has always failed at the same stop light about 1 mile from my driveway. It won't fail if I catch the green light and don't stop. The only time it didn't fail under the right scenario was a rare cool morning (about 48 degrees) when I deliberately let the car idle for about 10 minutes and then managed to catch the red light, it didn't fail (apparently because it was warmed up more).
It only fails once per day and is always 5 or 6 rapid knocks. It really sounds like someone rapped te side of the car. I catch myself looking in the side mirrior every time it happens.
So, I don't think this is an exhaust issue. I had a loose baffle in one of my Corvettes and that was an entirely different failure scenario.
If I take it to another dealer I will just be letting mine off the hook.
I truly like my fully loaded DTS performance Level. I am annoyed that they messed up the clock, the computer interface and the adaptive CC issue just gets strange looks when I bring it up. But nothing is perfect and I still don't want to own cars built by non US headquartered companies, especially former WWII enemies.  |
