Update: Rack replaced yesterday
The new rack finally came in and they replaced it yesterday; only time will tell if its a bad design or a group of bad parts that caused the issues for all of us. I've included the diagnosis portion of my repair order showing the code C0545-3a and GM telling the mechanic that there is a short in the torque sensor....I may have to go back though as it seems like my steering wheel is just a little off center...maybe.

A couple of comments about power steering failure. Plan on it on any car. There are all sorts of reasons why any power steering system will fail. On hydraulic systems a hose can fail or the engine can stop. On electric systems a component can fail.
GM made several cars with bad ignition switches that turned off easily while the car was being driven. The switch turning off that easy was GM's fault, the fact some people had accidents because the switch turned off thus turning off the engine and power steering was the driver's fault. It doesn't matter how reliable a system is it can still fail and the driver should be ready to drive the car to a safe stopping place alongside the road.
When I was teaching my granddaughter how to drive one of the things I did once she had some confidence driving was to turn off the ignition switch and let her get a feel for how the car handled without power steering and how she a small person could drive it even though it didn't have power steering. First I did it on a level straight and then after doing that a couple of times I did when we were going down hill around a curve. She handled it. Every driver needs to be able to handle it. When it happens unexpectedly adrenaline will drive your arms and you may thing it is easy to do but once the adrenaline flushes out of the system be ready to use your muscles without any help from a hormone.

I've found the reason the ignition switch could be turned off easily was due to too many keys on the key ring causing the switch to be turned to off when turning. This was in Cobalts that we were racing at the time.

Does the 2018 model have the same steering issue?

Hmm, had a September 2013 built C7, one of the first. Am on the forum often and don't recall any issues until recently. Sounds like a batch quality problem, IMO.
I would not call it an "issue" but rather a quality concern. This is not like the A8 where a new design has some teething problems. This is the same steering system that has been used on C7s from the start of production in August 2013.

Know your cars failure modes, and be prepared.

I'm wondering if in 2017 GM updated to redundant torque sensors, based on this failure I think it's unlikely as the short would have to happen to both sensors to cause a loss of assist.

Sounds like a bad batch of torque sensor cables. The steering system has an external cable running from the pinion tower to the ECU on the back of the motor. If this cable had a manufacturing issue then an intermittent short would produce your EXACT failure mode!

Same here
2017 z06 with the same problem. They're swapping the rack. My service guy knew what needed to be done immediately. Mine never stored a code and would start working after a restart. Seems more frequent on hot days at low speeds with ac on. Heat issue or related to heat perhaps?

It might be documented there. I actually don't have a copy of the repair order right now as the service writer said he was going to leave it open and just leave it on his desk for a while and see if this problem returns so that there's not a separate I repair. I'm not exactly sure why that matters but that's what they wanted to do.

it matters because those aholes have 3 times to fix a safety problem like that before it's a legal lemon and they have to buy it back. Go back in and get the paperwork and stop by your attorneys office to have him take care of the issue from here on. That's what I would do because I'm too old to F around anymore with GM's complete stupidity. Good Luck!

Hi there, Vista Vette,
I have just read ALL of your posts on this thread...Question:
So have you had any more issues with your PS since the dealer replaced your rack?
Mine failed on my new 2017 Stingray with Manual Transm. when I had 60 miles on it! (It was built in October 2016)
Flatbedded to closest dealer (Not where I bought it), of course they found no codes, said it was a low voltage issue, gave me a new battery and said case closed...
It failed again at 900 miles. I had read your thread, so I muscled up and pulled off the road, turned it off, counted til 10, turned it back on, warning message was gone, PS worked!
Then this morning, at 1000 miles, it failed 4 times in a row, and twice it did not go away after turning ignition off!
I crawled , with a white knuckle grip, to the dealer I bought it from and left it in their parking lot ...Not sure how loud I should scream at their service department in the AM ! What do you advise me to ask for!!!

Not one issue since it was replaced and I now have almost 15k miles. Just have them check for codes again, there has to be one stored. There were a couple of people on this forum that had the issue and found a loose ground wire. In my case, and most others on here, it was a faulty rack...or wiring within.

As I've said on other "p/s quits" threads, the new '17 I bought at Kerbeck's quit before I left with it. NO DIC messages and the Vette tech they called in on a Saturday afternoon said it was a "faulty sensor too difficult to reach to fix at that time." Hence, I doubt if it posted any codes, either. But, they seemed to know what was wrong.
After the tech reported, Kerbeck's sent me on my way in an identical '18 at the same price.

I know your posts are 1-1/2 yrs old but just to add to tghis I as well have a 2017 GS and had two occurrences of power streeing loss last summer. One was after sitting in a parking lot wirth the AC running and the second was driving on a highway at 75MPH. The first reset after a shut down and restart and the second didn't reset until 1-1-1/2 hrs later. I think it may be heat related, but the ground issue has merit
