Hi - I ordered a 2014 Corvette back in February and received in April. An auto, Z51, all options and have limped through the 500 mile break in and now have 590 miles and thought it was time to get on it a little. I took it out yesterday and got on it a few times but it seems you really have to mash the pedal way down to get the car moving. (I'm taking about just keeping up with the flow of traffic) As I was a little disappointed with the results I went ahead and headed back home. Once I pulled into my garage, I thought I would just hold the brake and give it a little gas to turn the tires over a little and was really bummed when I held the brake and mashed the pedal down a little, nothing, mashed it half way, nothing, then all the way to the floor, the car was running around 1500 rpm, but once again nothing. My stock C6 would have roasted the tires with approx. 1/4 throttle, at full throttle, I would have ended up in my living room! Any ideas? Other than this, I love the car but as I said, during normal driving it seams you have to almost put the pedal to the floor to keep up with traffic.

I have experienced this same problem from day one but just assumed the problem was with being limited on the amount of throttle you can give to keep it under the suggested rpm level until the break in is completed which has really kept the car in my garage parked.

GTriplett,

Sorry you have been experiencing this problem. While above suggestions will help, your car should accelerate 5X greater than the flow of traffic, regardless of what is on or off when you are mashing the pedal. You know what a Corvette is like and this is faster than your C6. Suggest you take that injured StingRay to your dealer and have them fix it.

Agreed, something is seriously wrong. They're is absolutely nothing in place during break in to govern the throttle. You should be able to roast the tires with 1 mile on the car. Obviously it's been broken since day one, so much for a real PDI from your dealer.

I Agree, it is not correct. Mine has worked as designed from day one, take her in for repair.

Thanks for all the information. I will get an appointment set up with my dealer. Just for the record, by switching to track mode and turning off the traction control did solve my issue with putting the power to the tires, although while driving it still seems like you have to give it 3/4 throttle to just get the car moving while in sport mode and traction control on. I keep comparing to my stock C6 but it seams I can leave most cars in the dust by simply playing with the first 1/4 throttle. (heck just feathering the throttle) Am I correct to assume that the car should perform like my C6 while in sport mode with the traction control on or do you have to switch to track mode and turn everything off when you drive it as I had never played with track mode seeing how I do not go to the track.

The C7 throttle does have a very numb tip in built into the program, it took me a few miles to get accustomed to it but nothing as bad as you describe.

However, when I switch back to my 2014 Hemi Ram it's like night and day. The Ram's tip in is much more responsive to the first 20% of travel. It's just how GM engineers program the throttle response. Personally, I wish they would allow throttle sensitivity to be adjusted independent of the mode like they do for steering.

GT;I have seen several owner reports that had the same symptoms you have described. I don't believe either of these links really cover your issue, but I do believe that a ECM re-flash will resolve your issue unless there is something more serious at its source. Look at these and see if either might be close. One is for a 7-speed only but I thought it was expanded to cover all, but I may be wrong about that. They are worth a look anyway. Let us know what you find out from your dealer.

Chip - Thanks a lot for your input. I travel a lot and getting the car to the dealer will be a challenge but will surely let you guys know what they find. It would be nice if an ECM re-flash would solve the issues. My experience with dealers is they typically give you the "can not duplicate the problem". So I try to research and once I find the problem I will just tell them what needs to be done.

GTriplett, like your whole plan, especially your researching ahead of time every thing you can, coming to the dealer with specific info on not only the specific symptoms of the problem, but what are potential or even probable causes, TSB's, etc.

Have found a great dealer who always allows me the opportunity to speak directly with the Technician before he starts working on my car, and then, when the Technician is done, he seeks me out, tells me what he has found, whether he needs to order parts for a repair visit, if there are any things we might look at at the next oil change, etc. I often then double back, thank the Service Writer and sometimes the Service Manager (even when they have little more than be polite), and to commend their Technician. Have referred other Corvette owners to them -- not one yet ever unhappy. To be candid, this was after trying/firing two other service departments.

I have had a similar experience. You definitely have to shop around to find the good service departments, and when you find a good one, hold on to them!

Keep in mind both controllers (PCM and TCM [if having A6 trannie]) have adaptive strategy and if the car was driven with the same drive style then that is how the controllers adjusted.

Now beyond the 500 miles best is to drive mixing up the drive style to include higher RPMs, loads, etc and then see how car reacts

Also in default mode and doing less then 5 MPH and less then 3,100 RPMs in V4 mode, add then :

1. Abuse mode
2. torque management
3. powerhop mode

May have effected your first attempt at wheel spin without controllers adjust time for the break in
Just a thought before going to the hassle of a dealer is drive more with less controls on and see how it adjusts

A dealer should plug in their Tech-II or tool they use and it should then connect to GM and if any controller updates found the tool should auto
install the updates.
