What stands out
No new NHTSA steering complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: 2018 Tahoe steering systems fail electrically without warning at any mileage, causing loss of power assist and stiff steering wheels—sometimes during highway driving with children aboard. Dealers struggle to source replacement parts, and GM's recall does not cover all VINs, leaving some owners unprotected despite identical failures.
Owners describe sudden, unpredictable loss of power steering assist in 2018 Tahoes, ranging from 22,000 to 120,000 miles. The failure typically triggers a "Power Steering Assist Fault" or "Steering Stopped Drive with Care" message, leaving the steering wheel stiff and nearly impossible to turn. The most dangerous scenario occurred mid-highway turn at 35–40 mph; another owner's wife was turning onto a highway when the steering seized, forcing the owner to grab the wheel to prevent a collision into a wall or canal while their young child was in the car.
The issue appears electrical or module-related. Dealers initially misdiagnose failures as battery problems—some owners report replacing batteries only to have the fault recur within weeks. When properly diagnosed, the root cause involves an open circuit in the rack and pinion mechanism or a faulty electric steering gear, but GM cannot source these parts in sufficient quantity, leaving vehicles stranded for weeks. One complaint mentions NHTSA Campaign 21V455000 (Steering), but not all 2018 Tahoe VINs are included, creating a coverage gap.
One owner also reports a cascade of electrical failures—dashboard shutdown, unwanted wiper activation, radio reset, and window malfunctions—coinciding with steering loss during low-speed maneuvers. At minimum, owners are calling this a severe safety defect; at worst, they're questioning whether the vehicle is drivable at all.

Failure modes owners describe
Power Steering Assist Electrical Fault / Loss of Assist
Complete or partial loss of power steering assist accompanied by 'Power Steering Assist Fault' or 'Steering Stopped Drive with Care' warning messages. Steering wheel becomes very stiff and extremely difficult to turn. Owners report this occurs without warning while driving or upon vehicle startup.
When: Between 22,000 and 120,000 miles; onset timing varies from startup to mid-drive
Symptoms owners cite: Power Steering Assist Fault message or 'Steering Stopped Drive with Care' warning; Steering wheel becomes stiff and nearly impossible to turn; Loss of power steering assist mid-turn at highway speeds (35–40 mph); Limp-mode behavior; vehicle difficult to maneuver; Intermittent fault clearing after 30 minutes to several hours, or clearing after restart
Repairs/costs cited: Dealers reported issues include: short in negative battery ground cable, open circuit in rack and pinion mechanism (unavailable as of complaint date), faulty 12-volt battery, and electric steering gear failure. One owner paid over $2,000 for repair and waited over two weeks for parts availability. Another owner's VIN was not included in NHTSA Campaign 21V455000.
Recalls/TSBs owners mention: NHTSA Campaign 21V455000 (Steering) exists; however, not all 2018 Tahoe VINs are covered. Dealers have attributed failures to battery issues and provided temporary fixes that recur within weeks to months. GM unable to source replacement rack and pinion parts due to reported excessive failures.
Steering System Electrical Cascade Faults / Dashboard Shutdown
Power steering loss accompanied by unintended electrical system behavior including dashboard shutdown, radio reset, wiper activation, window control failures, and tire sensor/compass recalibration. Suggests deeper electrical or module-level malfunction beyond isolated steering component.
When: Reported during low-speed maneuvering (parking, reversing)
Symptoms owners cite: Steering wheel hard to turn and locks momentarily at low speeds; Front dashboard shuts down and restarts (1 second cycle) while steering in reverse; Windshield wipers activate unexpectedly; Radio station resets and becomes unresponsive; Window control malfunctions; Park Assist Off light appears after steering event; Tire sensor reset and compass recalibration occur
Repairs/costs cited: No repair noted in complaint; vehicle condition left unresolved.
Steering Assist Reduced / Intermittent Loss During Highway Driving
Partial or reduced power steering assist occurring during highway operation, often accompanied by cruise control failure. Vehicle slows below highway speed unexpectedly, creating hazard.
When: Highway operation; one incident at approximately 120,000 miles
Symptoms owners cite: 'Steering Assist Is Reduced Drive With Care' message appears while driving on 2-lane state road; Cruise control stops working simultaneously; Vehicle speed drops below highway speed without driver input; Potential for rear-end collision due to unexpected slowdown

What owners are reporting 2 most recent
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.
