Yes, this seems to be a common CRD issue.
Symptoms are: Just out of the blue, feels like/runs on 2 cylinders, no acceleration/power, shakes like crazy at low RPMs, engine is very noisy, no CEL.
Mine did it today as a matter of fact, first time in about 3 years and ~50,000 miles.
You just need to pull off the road
when safe, shut off the key for at least 30 to 60 seconds, then start it up.
Runs like normal again.......
Please remember: It is
not "urgent" you pull off the road "immediately", just whenever it's safe to do so.
The engine will run fine, but with little power.
The first time you experience it, it's "scarey", but after that, you know what to do and go on.
FWIW, my '06 has done this 5 times in 138k miles, seems to happen in pairs with mine (within days of each other), then nothing for a long time.
So now I wait for the 2nd one..... .... ..
For all we know, this may just be the CRD computers "Clear the Catalyst" warning or something silly like that.
Hope this helps for you not to worry about it
