| Component | VEHICLE SPEED CONTROL |
| Product type code | VEHICLE |
| Description of the problem | On city street driving about 37 mph. Adaptive speed control engaged. I approach a car going the same direction slightly slower, about 35 mph. That slower car is following another car about 2 car lengths in front. My car gently breaks to bring my speed back to 35 mph. My 35 mph is being maintained at a fixed distance from the car in front of me. The car directly in front of me changes lane opening up a gap of about 3-4 car lengths to the car in front of me. My car now speeds up aggressively because there is no car directly in front of me. Instead of breaking when my car gets closer to the rear end of the car now that i am approaching, my car continues aggressive acceleration toward the rear of that car. My car would surely smash into the rear of that car if i don't brake significantly. This has happened several times through the years although not frequently given the conditions needed to experience the fault. I believe it is repeatable and suggestive of a software issue. All the hardware elements seem to be working just fine. |
