The turn signals on my 2026 KTM 390 Adventure do not function properly. They either fail completely or work intermittently. This creates a serious safety hazard because other drivers cannot see when I am turning or changing lanes. This increases the risk of a crash, especially in traffic or low light conditions. •“Problem happens every ride” •“Problem started at miles 10 •“Dealer could not fix” even replaced blinkers. I only have 32 miles on my bike.

1. The Turn Signal Malfunction indicator is randomly triggered. Observation indicates this occurs when the ambient temperature is under 60 degrees. When the error code is displayed, the turn signals are non-functional. 2. The first time this occurred I was several miles from home at dusk. I had to turn onto and off of a highway without turn signals. At that time of day hand signals are not easily seen. This is dangerous. 3. This is the second bike my dealer has recently sold with this issue. The dealer left my bike in an unheated area over night and were able to duplicate the fault the next morning. 4. An incident has been filed with the Manufacturer but they do not have a repair currently. They were aware of the issue. 5. A warning light appears on the TFT dash when the fault is detected.
