While driving, a “Service ESC” warning message appeared and the vehicle suddenly lost power steering assist, causing the steering to become extremely difficult and creating a serious safety risk while the vehicle was in motion. The vehicle was taken to a service center, where technicians found multiple loss-of-communication codes involving the electronic power steering system. Further inspection found the main electronic power steering connector full of water and corroded. The technician documented that water intrusion caused excessive damage to the electronic power steering terminals at the rack-and-pinion assembly. The water intrusion appears consistent with a failure or inadequacy of the sealing intended to protect the electronic power steering connection from moisture. Due to the extent of the corrosion and damage, the affected wiring harnesses and rack-and-pinion assembly had to be replaced, followed by a wheel alignment. This failure resulted in a sudden loss of power steering assist while the vehicle was being driven.

The vehicle's power steering does not work properly, especially at slow speeds and when attempting to back up. However, it has also failed while traveling on the interstate highway at high speeds. When you attempt to make a turn, the power steering feels like it is fighting you and wants to pull the vehicle back in the opposite direction. I took the vehicle in to be serviced, and they replaced the battery which removed previous warning messages. On two occasions, while traveling at slow speeds and making a turn into a shopping center parking lot, the vehicle resisted my attempt to make the turn such that had a car been coming out of the parking lot, rather than complete the turn, I would have run directly into the side of the other vehicle. While travelling on the interstate at 70 mph, I momentarily lost steering and had there been vehicles behind or beside me at the time, I believe it would have resulted in an accident. Fortunately, the cruise control simultaneously shut off.

Initial Diagnosis: We had the vehicle towed to a dealership for repair after losing steering while driving. The dealer's service department informed us that the issue was caused by water and corrosion in the electric power steering rack. They also indicated that this is a known issue, suggesting that the wiring harness seals are failing and allowing water to damage the system. Video the dealership sent us of the issue can be seen at [XXX] Repair Timeline: On July 30, 2025 I was informed that the replacement part for the steering rack was on backorder for approximately 45 days. After waiting 56 days, I contacted the dealer again on September 25. They informed me that they were unable to get the part. The dealer stated they could not locate the part even after contacting other dealerships, suggesting a widespread shortage. The reason given was a high volume of similar repairs. Requested Action: I am reporting this to the federal safety agency because the sudden loss of steering is a severe safety defect. The widespread parts shortage suggests this is a common failure. The manufacturer needs to address this issue and provide a remedy to prevent accidents. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
