The honk stopped functioning on January 21 2026. I noticed this when a car was moving into my lane on a major highway and I need to honk to alert them. Not being able to alert another drive that they are about to hit me puts me, the other driver, and potentially others at risk. I had to break hard, which is also a safety hazard. The honk has not functioned since, so it was not an isolated issue. No warning lights went on. I have scheduled an appointment with the bridgewater dealership for Friday January 30.
1) electronic emergency brake goes on repeatedly when attempting to put vehicle in gear. 2) speed control has coasted to a very low speed while on the highway several times, on its own with no vehicles in front of me. 3) numerous other “glitchy” electrical issues exist. Dealer says they are collaborating with engineers in germany. There is currently no fix. It is as if the vehicle is always cycling through various “glitches”.
On two separate occasions, approximately four months apart in spring and summer 2026, while turning left across oncoming traffic at a green light, the vehicle's brakes applied hard on their own with no driver input. Each time the vehicle came to an abrupt halt mid-turn for roughly one second before releasing. On both occasions a driver-assistance warning message displayed on the dashboard at the time of the event. Because this occurred while turning in front of oncoming traffic, it created a serious risk of a collision. The exact dates were not recorded. These events occurred after a battery replacement performed at the dealership in February 2026. This is reported so it is on record under this vehicle's VIN and can be compared against similar reports of unintended or self-activating braking on this platform.
