09 CTS with the non-DI 3.6 and no misfire here at all,almost a year old with 15K on it......when you say a misfire....I assume a cylinder not firing from the plug....have you replaced the plugs?....you say you have checked new 09 Mailbus, G8s and CTSs and they ALL exhibit the same misfire.....fine that one hard to beleive so perhaps we need a better description of this misfire...is it a hestiation on acceleration, or during sustained driving...or at idle?......when you say GM told you....was that from you dealership or was that from the GM help line?....
BTW, please turn your CAPS off!

The misfire does not apply to D.I. 3.6 ltr. engine.Dealer service techs. have experianced the misfire on brand new cars on there lots.A service writer told me since i complained of the misfire,every car coming in for service with this engine has the same problem.This is a constant miss and no plugs have been changed but 2 injectors and 1 oxygen sensor have been changed.I recently went to a Cadillac dealer and was told GM engineers are working on a fix.The Cadillac dealer had the car for 2 days was unable to fix the misfire.I have also been in contact with GM customer service,i get the same story engineers are trying to find a fix.For your information i work for an engine manufacturer,maybe thats why i am more aware of the misfire than a normal person would be.Thanks for your interest in my problem.maliblues1

does the miss occur at idle only?

you have to pay close attention to feel the misfire,it feels like a slight tremor and it may just do it once or two or three times in a row. the misfire occures at idle and between 1000-1500rpm.i can really feel it when the car is first started cold.i was at the cadillac dealer today to see if they had heard from gm engineering,not a word.i am surprized no gm tech. has replied to my blog.be thankful you didn't buy the direct injection 3.6 while i was there a customer came complaining of a engine noise.service writer and the mechanic who worked on my car told the customer the noise comes from the high pressure fuel pump and is "normal".they both said this is a common complaint for this engine.if i were a cadillac owner i wouldn't even want to hear the clock.do you think this customer and others who have this problem will buy another cadillac? we both know the answer to this. have you read of this problem on cts blog site ?

I been having a misfire with my V6 2005 Malibu. At least that's what they say it is. It started a few weeks ago, I would notice it on the highway at around 80km when the engine is warm. Feels like I'm driving on a washboard. Car shakes for a couple seconds. Keeps doing it intermitently.
Dealer was at odds when I explained it. Took it on a test drive and felt it.Believes it is a "fishbite misfire". Suggested I pay for a fuel injector flush, which I had to pay for inspite of being under extended warranty, because he said it was "maintenance."
That was two weeks ago. Still does it. He now suggests I use super clean fuel, which I've been doing to no avail.

I guess noise and the misfire you state are relative or rather sensitive to various individuals....some notice it or it bothers them...others it doesnt....as far as your question about the DI noise....No havent seen it on the major cady forum I look into either....

dealer tech. told me its a programing issue,92 octane gas,injector flush or replacement will not fix the problem.GM engineering is "supposed to working on a fix".i have had this problem for over a year,went to 3 different dealers,stll have it.Thank You GM !! This will be the last american car i buy.Malibues1

i guess people have different expectations when it comes to how their vehicle performs.i belive in this day and age with all the technology available you should have a smooth running engine and a transmission that doesn't slam and bang when it shifts.You also shouldn't have to put up with rattles coming from the sunroof and seat.As for the Cadillac DI noise i witnessed it first hand at a Cadillac dealer.The customer came with his 2009 CTS complaining of engine noise,sounded like pennys rattling in a can,service tech, told "its normal" and could not be fixed.The guy peeled rubber out of there,think he will buy another cadillac? tech said some cars are noiser than others,got the same story from chevy tech.

i get no error codes or check engine light on my 2008 car. i have been waiting 1 year for a fix from a gm engineer.i think we need more owners to complain on line to get any action from gm.i experianced a misfire on 4 new cars with the 3.6 ltr.V6,two 09 malibu's,09 pontiac g8 and 09 caddy cts.two differant dealer serv.techs.also had misfires on brand new cars in the dealers lots.i am sure gm knows it has a programing problem with these engines but as long as they can still sell cars with this problem they will.maliblues1

I did not see anything about the test procedure.
Were the probes put into the radiator or where?
If the coolant was becoming acid, then he might have read a voltage by having to probes of different metals.
Voltage is merely and indication that a charge is present. Current, amps, would indicate how much of that charge is being displaced, that is that corrosion is taking place at a specific rate.
