While driving on local roads to break in the engine, the car stalled from fifty miles per hour to five miles per hour for about five seconds at mile approximately 100 and 650. No cross traffic or pedestrians. The car detected and warned another car more than three hundred feet away at approximately five hundred miles and nine out of ten times fails to recognize a car a few feet away. The master mechanic did a ride-along and witnessed the Collision Mitigation System failure. Offered âre-aimâ as a solution. A week later, he confirmed that he did not expect it to fix it. It was to satisfy me. The service manager repeated the same a week later that the fix was to go through âmotionâ. The dealer is relying on computer codes and ignoring the human observation of the problem during the ride-along. The master mechanic suggested that if there should be a rear-end collision, it would be the fault of the car behind. That is not a risk I like to take with my daughter on a highway. The car sees obstacles that are not present and fails to see the obstacles that are a few feet away.
