I'm looking for an electronic rack and pinion assembly preferably, remanufactured for a 2012 GMC GMC Yukon Denali Hybrid 6.0L 5967CC 364Cu. In. V8 FULL HYBRID EV-FLEX (FHEV) OHV Naturally Aspirated. Does anyone have an suggestions?

Moved from GM Electric Vehicles- EVs to GMC/Chevrolet Truck/SUV .

Wow, that'* a big ask. Looks like they are long out of production. There are a few used ones on Ebay. Otherwise there doesn't seem to be any.

What'* wrong with the current one?

Service power steering light is on. No power steering at all. When you turn the wheel computer not reading any movement.

Did it degrade slowly or fail quickly?

Took it to store and it worked fine. 30 minutes later no power steering.

Have you done any diagnosis beyond this? It might not be the steering gear that'* bad.

Had the local shop look at it and that’* what they think the issue is. I’ve also read that there’* a known issues with the electric motor shaft breaking. So not sure the best way to proceed.

Well . . . this comes down to diagnostics. I can't speak to the shop'* ability to diagnose nor for what specific fault(*) they found.

Did they find a broken shaft?

Was it pulling current when assist was needed?

Does it "try" to do anything at all?

Are any sounds heard from it?

. . . or did they say "Yuuuup, it sure dern't work none. Never seen onena these hah-brid steerin' racks befower, but eit shure looks shot tuh me!"

Not meaning any disrespect to your shop, I just know nothing about them from this side of the Internet, and this kind of thing happens often.

If the ball is now in your court, are you able and willing to swap it out yourself?

If so, there are some used units available on Ebay. I can't speak to seller reputation or parts quality, but they're there. If you got a working one and it fixes the problem, great news! If you got a working one and it doesn't fix the problem, likely the issue is somewhere else, but hang onto the extra unit because they are hard to come by, and you'll need it someday.

Looking around on the market, the shop would probably have to go the same route if it is still there. They likely won't warranty the part or the labor if it fails, but they could probably install it if they are willing.

The other question that nobody wants to ask: What is the condition of the rest of the vehicle? Is it in good condition? How old are the batteries? Has all of the service been kept up? Were you planning on selling it soon anyways?

These hybrid full-size SUVs were a great idea by GM IMHO. They quietly solved a good problem in a good way, and they quietly just lived their lives without much fuss. The problem with such a unique, and short-lived, vehicle is that the small problems become harder and harder to support as they age.

Vehicle is in very good condition. Shop has admitted they aren’t sure what the problem is. I’m thinking it may be time to get rid of it and cut bait.
