I bought my SR on 9/22/2018 and did not have the optional impact sensors installed. If these are the sensors that are causing the crash warning, then sorry, this feedback does not help you troubleshoot. All of the other sensors (cameras, blind spot warning, emergency breaking, etc.) seem to work fine on my car. Is it the impact sensor that is causing your problem?
When I checked on impact sensors, I noticed it's a hundred (US) dollar option. Here is what the impact sensors are supposed to do: Impact sensors are designed to detect instances of sudden impact or severe vibration.
- Provides a quick chirp of the horn when a small impact is detected.
- Full alarm activated when attempted wheel theft or break in is detected
- Provides audible alert on start up if an impact was detected while you were away
I would suggest to the dealer that they uninstall this option and refund the difference. Fourteen days is excess.
