Details: 08 C6 auto 22 k miles, bought from chevy dealer, has extended warranty. Besides whole list of issues heres the latest.Problems: now with increasing frequency whether it be from a stop light or merging onto highway, pressing gas to start going or merging will result in absoloutely no response as if your pressing the gas whie car is not running .Rpms dont even move. It almost caused a near rear end collision of my p.o.s. Vette on the highway yesterday. Or mashing pedal to get it going while people honk at you at a red light usually takes about 5 seconds of flooring it to respond with as usual weak throttle response. Since purchased, car has had clunky, jerking, delayed, banging,inconsistent,harsh gear changing/acceleration, alnost feels like a 4 cylinder with 500k miles on motor type power, been to 3 differant dealers First one says :until breaks down, theres nothing we can do. Second one says: were not gonna start pulling it apart and look for problems .3rd on says : This is normal for it to run like absoloute s$!t pulling 0-60 times in about 6 seconds going down hill no less. Around 4.5 for automatics would be more reasonable. . I thinking tranny issues, at 22k miles is heinous,way to go GM.Any thoughts ANYBODY ??? This car absoloutely sucks in plain engish.

Hope someone helps you find and solve these problems. I've had several A6 C6s and none of them had these kinds of problems. Still have an A6 012 coupe.

With driving that bad you think you be throwing codes left and right, nothing? 22k on the odo is nothing, clean history on the car?

May need to elaborate more this condition.
Does not sound like so much tranny issues but engine running problems. Does the engine rev but trans not engaging?. Here's a long shot, make sure you use traction control, having it off make the throttle response sluggish.
Fuel system could be compromised, low pressure will make sluggish response.

After reading various car/truck forums, the first thing I would do is see if you have a factory/stock tune on your car. Seems like everyone throws an aftermarket tune on everything. If you purchased it used, you never know, could be someone put crappy tune on it that's screwing things up.

PatriotsGuy

Yup clean carfax clean vehicle check also had maintence performed in history of vehicle.

PatriotsGuy

Engine does not rev its like pressing gas with car off or stalled, car has been a nightmare with no one being able diagnose issue poorly trained young techs relying on codes instead of figuring out problem like they did pre 90s era before everything went computerised.

I'm thinking maybe a bad accelerator pedal position sensor.

My 08 A6 runs fine. No issues as of yet. 7200k miles on it.

Did they start easy with spark plugs? Coils?

Not So Fast

Where is the Chevrolet Customer relations person at that usually pops up about this time?????

wayback

That or even MAF sensor. When my maf connection got wet the car acted like it was in N.

Both of these should throw a code. I find it hard to believe there are no codes.

Are there any reputable tuners close to you?

There is not enuff info given, so just guessing is resulting in some pretty good guesses.

What does this sentence mean: "...also had maintence performed in history of vehicle"? The "history" question (Ricardo) on the car is not just CarFax, as you probably already know. It can also be the IVH which is only at the dealer (and is free to find/read/print).

To see if the engine/trans has had a tune (a bad one or any at all) someone is going to have to specifically check for that at your dealer (or elsewhere).

Good luck. You might want to disclose what city you live in (with 3 dealers) because someone on here might know of either a good dealer or a good indie shop.

PatriotsGuy

Well this is the latest problem just started yesterday, has not been in shop for tjis current issue.but previous problems have been met with unwilling to assist service dept, who says they wont get paid if they start looking for problems, what do i have to do walk in there like a raging bull demanding they fix my car .I live in a rural area not that many chevy dealers in close proximity.

PatriotsGuy

Thats what isaid before, but they refused

PatriotsGuy

I meant, that carfax showed that previous owner did maintenance (oil change ,battery check, etc) on vehicle. Dont know if there are tuner shops around here, i refuse to pay out of pocket if its under warranty that i bought no less.

This last bit of information, rural living could hinder you for sure. Worth a trip to a Corvette or LS engine specialty shop. Maybe the deletes hips do not have much experience with the Corvette. Not that it should matter with most issues. No codes is a puzzler too.

This latest problem should be easily trouble shooted.

Wonder if yo got a flood damaged car?

I would not trust Carfax as far as I could throw them.

PatriotsGuy

The only code it ever showed was before this latest problem that said something like fuel or oxygen to rich ?that was done at advance auto and i nor the guy that ran check knows what that means .Then broght to dealer next day and they said theres no code or they deleted it , beats me man.

ruxvette

Jeez, ya know...you posted in May, you posted in July, now you post in September about the pos vette you own.
Where are you? Perhaps somebody local to you can help remedy the problem.
Damn.
