I purchased my stingray about a month ago from a dealership out of state. I had it shipped to colorado where I live.
Shortly after I took delivery, I noticed it pulled to the right starting at about 40mph.
I took it into the local Chevy dealer and they covered the alignment under warranty. I travel for work so only drive it a couple times a week when it isn't raining. Shortly after the first alignment, it was STILL pulling right. Frustrated I went back to the dealership with the car. I left it there over the week while I was away. They soon informed me they were using the wrong specs.. And that the issue should be resolved. I was elated to get her back. But damned if not a few days later... I for the 3rd time return to the dealership and take their service director on a ride to show him the pull. Knowing the situation he is baffled. Upon returning to the dealership to schedule an appointment, a service rep informs me that the second time the vette came through the GM techs had informed the mechanic to "offset" the caster to compensate for the pull. The mechanic and service rep both thought this was odd. I'm under the impression they had rigged the alignment and not followed specs. ( which still has not resolved the issue) my question to anyone who may have any insight is: would an "offset" outside normal specs be the proper method of rectifying this because both the mechanic and service rep thought it was wrong..and my next step is to get an attorney. I don't want this to take away from my love of the car as its been my dream to have one. It appears to me they don't have an explanation as to why it continues to pull right and want to cover it up. Lemon laws in colorado state 4 attempts to fix the problem and them GM needs to make it right. Any thoughts? 2014 3LT Z51. They apparently had applied the proper specs the first time.

It's a common trick to offset caster to resolve crowned road pull but not something I would accept on a sports car. I would ask for a realignment precisely to the specs, no +- crap or inside the green box, get the numbers spot on. if it still pulls then you have a bad tire, rotate them left to right and see if it clears or changes the pull.

Mark, thanks for the reply. I agree with you. That's why we have specs and I've made my frustration clear. They did troubleshoot by swapping tires and that also didn't resolve the issue. I hope they make it right.

Hmm, if they aligned the car and swapped tires and it still pulled that leaves either their machine calibration or the tech's use of the machine in question. Time to try another shop. Probably won't get it done for free though. Personally, the ONLY dealer I've ever had luck with was my Porsche dealer. Never once in 40 years of owning cars has the local Chevy dealer been the go to place for alignments.

Thanks. It was still pulling to the right after swapping front wheels??
Then swap the rears. In fact, I would check to make sure they followed the prescribed rear caster setting procedure with the special tool. It requires more then simply using a rear wheel mounted sensor on the alignment rack since those only measure camber and toe. Non-steerable wheels need a CH-47960 Angle Gauge or equivalent to measure and adjust caster. It attaches to the rear knuckle and measures the fore/aft alignment of the upper and lower control arms, a.k.a. caster.

Rear alignment can cause a pull or drift just as easily as a bad front alignment.

Mark you seem to be a wealth of knowledge. Thank you again. I am waiting to hear their response. I just want to confirm that going outside the specs such as "off setting" the caster is NOT standard protocol and that they are wrong in doing so. Just in case they come back with the excuse they stand by their work and the word of some "engineer" for GM. It's my understanding they exhausted all options including swapping the rears and that was why they called GM. I just want to drive the damn thing. Going on the 3rd attempt of trying to fix this problem.

Offsetting caster isn't that big a deal but it's not something I would consider a fix, just a band aid. I would ask to have the car checked on another alignment rack and once certified to be in perfect alignment demand new tires all around. A brand new car in perfect alignment should not pull to the right or the left.
