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.

Power steering went out with kids in the car when vehicle only had 76000 miles. There was a special coverage for 2018 models that my vin was not a part of. Had it been this wouldn't have happened to my family. I was without a vehicle for over 2 weeks since dealership had to reach out to GM to find the part. Apparently, this is big issue for other models and years which explains the part shortage. A few months prior there was a service power steering on my dash, and I couldn't turn my steering wheel. Took it to dealership and they brushed it off as computer issue. Again, I feel if my vehicle was part of the special coverage, I wouldn't have experienced this issue or had to pay over $2000 to repair it.

My wife was driving everything was working fine until a message came on the dash "steering stopped Drive with care" she was mid way in a turn to get on highway when this happened if I wasn't in vehicle to grab the wheel my wife would have ended up in a wall or worst case in the canal next to 95 with my 4 year old in the car. The vehicle is currently at a chevorlet dealer in Greenacres Florida and they say the electric steering gear has stopped working.. this seams like a very unsafe system as when it stops the steering wheel is very stiff more than a old car with no power steering. I think this needs to be investigated yesterday as someone could die from this if it hasn't happened already. As of right now I no longer feel that this is a safe vehicle for my wife to be driving

2018 Tahoe w/ 60,000 miles began riding extremely rough any speed. So much bounce and jarring that the car is unsafe to drive on any rough road.

When stationary and turning on vehicle I had difficulty turning steering wheel. I received a notification that power assist was not active. This happened once before and I took to dealer. They claimed it was the battery and replaced. I see there have been prior recalls on Tahoe for steering assist issues.

Thank god my wife or someone wasn't driving at this time : got in the vehicle, started and a service vehicle came on.. it said ' power steering drive with care '. I could not even turn the steering wheel. I guess a steering module or a software update is needed. Called local Chevy dealer and they said call back Monday. Bought Tahoe brand new in 2018, only has 22K miles. I'm stuck not driving the vehicle till Monday.
