NHTSA Complaint #11599841 — 2018 CHEVROLET TAHOE

First occasion the car drove fine with no indication of an issue. Then once the car was turned off then on, the dash showed no lights or gauges and indicated that the steering assist is not working and the wheel was impossible to turn (almost like a limp mode but not driveable). Disconnected the battery to try and clear the issue and car drove home fine. Was told it could be a bad battery so replaced the battery and it worked fine for about a month. Then again with no indication did it again and this time it cleared itself after about 30 minutes. Dealer said there was a short in the negative battery ground cable and an open circuit in the rack and pinion mechanism but that the rack and pinion part was not available and they weren’t sure when it would be (probably due to excessive failures). Replaced the negative battery ground part and everything was fine for about 3 months until today when the car did the same thing again. We will have to keep looking for the unavailable part or I will basically have a $30k paper weight. Very concerned at the possibility that the steering will go out while I am driving as others have mentioned in previous posts. Seems as though something tragic will have to happen before they issue a recall of a part that appears to be a common failure.
