Usually this takes about 30 minutes of heavy rain to cause the. All other functions of the vehicle work but most safety systems appear to deactivate because of the sensors. This sho
Trunk is defective. Trunk will not open unless it is manually opened, which is hard because it is powered. If there is an accident and a person needs to escape, they would be stuck inside due to these defective trunks. Many others are experiencing this issue online.

In heavy rain situations I get an error message stating all front active safety systems (forward collision warning, etc.) do not work.

Car was running normally and going at 50mph then all of a sudden car abruptly lost power and went to 10mph and dashboard lit up.
