My SC tried to fix this. Replaced the DOS module for AP. Problem still happening. Anyone else get this issue successfully fixed? Its intermittent and happens randomly. Only way to fix it is to walk away from the car, or have them send a reset signal to the car.
Yes. I have had this exact same problem. Seems like all sensors will not report to the MCU, but there is no indication of it. Symptoms:
- Most noticeably the GPS of the vehicle is stuck in the last place I left the car. Says to me that GPS is not reporting.
- I have auto brights turned on. Brights will turn on regardless of time of day, or my proximity to other vehicles. Tells me light sensor and radar not reporting.
- Vehicle cannot read lane lines, nor see vehicles in front of it. No TACC or EAP. Tells me cameras are not reporting, ditto on radar.
- Sonar not reporting. No beeps, or colored arcs around vehicle on binnacle to indicate proximity to anything around the car. Tells me sonar is not reporting.
In my experience with this, essentially every sensor stops reporting. This is an intermittent problem, but the car never reports that its capabilities are diminished (whereas sometimes you might see warnings about park assist not being available). I can only imagine that collision warnings and automatic emergency braking are also not functional when the car is in this state. I have had this happen to my vehicle on four separate occasions since March 10. I had a service appointment last week, upon return of my vehicle the tech indicated that the issue was a known issue and would be addressed in a future software release.
I have been able to correct the issue by powering the vehicle down entirely, waiting a few minutes and then pressing the brake to turn it back on. You may notice the car will not STAY powered off. This was described to me as a function of a part of the car always being awake, and certain activity awakening the vehicle from a powered off state. Anyway, this has always worked for me. Rebooting the MCU with the scroll wheels will NOT work.
I recommend attempting to get a video of this behavior if you are able to do so safely. My SC had a very hard time understanding what I was trying to tell them.
Here's hoping that this is a software issue that will be resolved very soon. I must say it is a bit disconcerting to be driving a vehicle who's suite of sensors designed to provide an extra layer of safety intermittently stop reporting, and give no indication that there is a functional problem to the driver.
