2017 RDX AWD ADV. 33k miles. In service 2/17

Hello All, I have some very unusual malfunctions occurring. Conditions have been anywhere from sunny day mid 70º's to rainy, dreary, mid 50º's. I have not been able to find anything similar to this on lline.

--First occurrence about a month ago, 70MPH on an interstate the LKAS system suddenly starts inputting steering corrections. I was not using the cruise control and the "Main" was not engaged. The system should have been completely off. The LKAS motors continued to fight my inputs as I exited the interstate and turned into a parking lot. I turned the vehicle off to let the system clear. Drove another 20 miles and it re-occurred. LKAS, ACC, and CAS indicators all light up, as well as error messages on the monitor. Drove a few hundred miles on my return trip home the next day with no incident. Had dealer investigate and was told a dirty sensor was the likely culprit.

--Several additional occurences over the next few weeks. The indicators and error messages will light up, then go away, then repeat. All the systems involved with the LKAS are turned off. The LKAS motors will constantly input movements into the steering wheel. The movement are very sudden and very un-nerving. During these times I was able to easily over ride the inputs and steer the vehicle. Scheduled another visit to dealer.

--One day before visit scheduled, after sitting at a red light, proceeded to turn left on green. Had accelerated to around 20-25mph. The LKAS motor suddenly engage wanting to steer the car to the right. This time, the malfunction nearly pulled the steering wheel out of my hands, and I had to use a very strong force to over ride the system. Immediately drove the vehicle to the dealer and informed them it was undrivable and unsafe, and advised they warn the tech before he took the car out and attempted to replicate.

Has anyone seen anything this severe happen with thier LKAS? If so, was it remedied and how so?

Thanks in advance!!
