81 vette , very nice

 

01 Alero -- eeewwwww

 

03 Blazer --hate 'em lol

 

11 enclave -- nice

 

14 - silvi -- nice

 

I Still have nightmares because of those 2 veh's you have , lol

 

I hated W body cars as well , they are awful , T Blazers are a bitch to get an engine or tranny or t case out of , just awful lol

 

I think of them and I get a shiver down my back , thx for that lol

 

In the end thou if there are no codes ( insert your name name here) , there is nothing wrong and very well be a normal condition , just saying , I've never worked on those new veh's as I've been out since 08 ,

 

Have an open mind , road test with shop foreman and have him show YOU why it's normal if at all ,

 

Good luck ( insert your name again ) , let us/ me know wtf they say please ,

 

Any GM TECH is my automatic friend here just from sharing the same bullshit no matter the country in which we worked .

And you know they will say this ???,

 

If your SES if OFF they will scan it anyways and try to do something but if there is nothing wrong with it please see a dodge or Ford store to completely satisfy your automotive repair concern .

I dont know what your issue is but when I am spending 47,000 dollars for a truck I expect it to be running for a long time. Second I was a cert. GM mechanic for years and I got out of this field because of the bull-shit these guys run past GM owners. Yes, if I take this to the dealership with out knowing what is happening there answer is always and I quote: " its normal" every time and it just is not me its all my clients I deal with go through this. Finally I would have hoped for a better return answer but the last time I checked Ford & Dodge have been running away from gm for years now, My problem as being a loyal GM owner this is the shit I have to deal with. Maybe GM can get there head out of there ass if they get people like yourself out of answer GM owner concerns. I take it you must have worked at a dealship to have the remark like you did......

be sure to get them to ride with you and witness the noise and rough vibration. they get paid by GM to repair these trucks, so they surely won't blow you off if they can identify a problem.

I was a tech for 14 yrs and I now have toyotas in my stable instead of GM , because I had to many new GM veh's on my hoist ,

As a former tech you should know the process and not be so dam assuming of the outcome of a service visit ,

 

Sometimes a NFF, ( no fault found)is presented because of misinformation or customer not knowing the behaviour IS infact normal , what needs to be done is this has to be explained to the customer as to why it's normal ,

 

What year did you leave the dealer life ?

 

I hated and loved flat rate , I loved wearing GM coveralls , I loved rebuilding transmissions one after the other , I loved being a cheating whore , what I hated the most was management , they didn't have a clue , I hated warranty times getting knocked back ,

 

I'm glad I did all those years with and now have the best retirement job ever , back fixing cars & trucks on an army base , this time as a civilian ,

 

As mentioned road test with a shop Forman , which you know to do already

 

Good luck , have a merry Xmas

Hey thanks for a good text back better than the first one. I was a gm tech with my masters for 8 years with GM, I agree that the people in charge are one of GM's main problems in the service dept. were we live its a bigger problem they dont want to pay these guys the money they deserve so they get these fly by night techs that have no glue about these cars now. Look I worked on peoples cars since I was seven years old there is no more back yard tech anymore. What I am looking for is some feed back about what I should be telling them what we need to be looking at, or the answer I will get back is " its normal ". Look I love this truck I think GM is way back on the path of being a great car builder again, and I have owned a lot of GM products and I still have 81 corvette, 2001 Alero, 2003 blazer extreme, 2011 Buick Enclave and my Silverado plus I had a deville which I traded in on the truck and I had though when I bought The Enclave Gm was on there way back the truck Wow its built. But Like anything else things happen and I know running rough and viberation in V4 is not normal.

Now that i think about it, the truck does run just barely noticeably rough in v4 mode. It feels sort of like driving a manual transmission in 5th gear when you should be in low 3rd, but not nearly as bad. If your vibration is similar to what I'm describing, then it might be a normal phenomenon.
