A lack of power steering could be dangerous in any car, but we are talking about vehicles weighing nearly 6,000 pounds, so the risk of having no power steering could be disastrous.

So far, GM has not issued a timetable for when this issue will be resolved. The recall notice says "GM will notify owners, and dealers will update the EPS module software, free of charge," but there is no warning that the trucks and SUVs are unsafe to drive. If you do own one of the Chevy, GMC, or Cadillac models affected, just stay alert in case you feel the steering wheel suddenly get heavy, then return to normal.
