Throttle Failure
A friends weekend vacation was recently ruined when his 2015 Roadster threw a code and went into limp mode. The local stealership claimed the problem was a result of shorted wire underneath the drivers "dead pedal". The claim was a screw (factory) penetrated a wire (bundle) that was part of the throttle system.
We'll know more later. For now its a "heads up" to anyone with a similar problem.

Heck of a strange thing to happen. Hope that's all it was and the fix is easy.

Some follow up on my buddys dilemma.
After the first failure and "repair" by a dealership, the car made it for a day.
Then the second event happened while driving. The car just shutdown!
After pulling off and restarting, all seemed fine so I followed him to a different dealership.
They had it for a week (replaced the throttle sender sensor) and during the drive home the car died yet again.
Now the dealership has spent two weeks and called to tell him they are unable to correct the problem.
He will be getting his money back, and chances are another C7 will not reside in his garage.
Bummer

Hopefully this is the final note.
Problem: Coolant seeping from the overflow tank cap on to wiring harness below.
Thus causing corrosion in a harness connector, which includes the throttle circuit.
Fix: Clean connector contacts and lube with di-electric grease. Replace cap with new seal.
No more leaks. No more codes/problem.
Many thanks to Abel Chevrolet for their perseverance...

I just sold my 67 convertible because it was time to move on and have been lurking here to learn about the "themes" of the new C7.
I rewired my 67 end-to-end to alleviate the electrical gremlins and I still had occasional issues.
B/L: electrical issues can be very deceiving...like in this case...the initial focus was on the throttle BUT the issue was the radiator cap seal...
Its enough to drive a person crazy!!
Glad it was fixed!
Cheers,
Frank

Yep they did good. Real good.
I hope that many others read this problem and can take care of it before your out there hammering down.

Actually NOT. After 3500 miles he's reluctant to drive it any where's.
The code has become persistent. Four times fixed now.
At the end of August he applied for a "lemon law" return.
After many promised phone calls the General denied his claim.
So what's next? A lawyer?
I suggested he take it back to the dealer of origin and have them sell it or trade it.
But with their lack of assistance, he's not ready to buy from them again.
Anyone have a suggestion that might help him back into a reliable C7?

Since you are in CA, I assume your friend is also in CA. CA's basic definition of a "lemon":
Your friend needs to follow the procedures outlined in: http://www.dca.ca.gov/acp/pdf_files/englemn.pdf
Lemon Law Presumption*
Within the Song-Beverly Act, there is a presumption guideline wherein it is presumed that a vehicle is a “lemon” if the following criteria are met within 18 months of delivery to the buyer or lessee or 18,000 miles on the vehicle’s odometer, whichever comes first:
If these criteria are met, the Lemon Law presumes that the buyer or lessee is entitled to a replacement vehicle or a refund of the purchase price. However, this presumption is rebuttable. The manufacturer may show that the criteria has not been met (for example, because the problems are minor) and therefore, the buyer or lessee is not entitled to a replacement vehicle or refund.
*Source: California Civil Code Section 1793.22(b).
Within the Song-Beverly Act, there is a presumption guideline wherein it is presumed that a vehicle is a “lemon” if the following criteria are met within 18 months of delivery to the buyer or lessee or 18,000 miles on the vehicle’s odometer, whichever comes first:
- The manufacturer or its agents have made two or more attempts to repair a warranty problem that results in a condition that is likely to cause death or serious bodily injury if the vehicle is driven;
- The manufacturer or its agents have made four or more attempts to repair the same warranty problem; or
- The vehicle has been out of service for more than 30 days (not necessarily all at the same time) while being repaired for any number of warranty problems; or
- The problems are covered by the warranty, substantially reduce the vehicle’s use, value, or safety to the consumer and are not caused by abuse of the vehicle;
- If required by the warranty materials or by the owner’s manual, the consumer has to directly notify the manufacturer about the problem(s), preferably in writing. The notice must be sent to the address shown in the warranty or owner’s manual (for bullets 1 and 2).
If these criteria are met, the Lemon Law presumes that the buyer or lessee is entitled to a replacement vehicle or a refund of the purchase price. However, this presumption is rebuttable. The manufacturer may show that the criteria has not been met (for example, because the problems are minor) and therefore, the buyer or lessee is not entitled to a replacement vehicle or refund.

Repaired and recurred four times.
Owner suffers from COPD and should the car fail when cell service is unavailable....
First event at 3500 miles
Car purchased new in jan this year.
Situation sux for him as he's an avid Vette owner with three C2s.
Not really ready to give up but time is limited.
He'll probably lawyer up
