Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

Electrical
Filed Mar 27, 2026

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.

Manufacturer communications

A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.

EXTERIOR LIGHTING

KTM North America, Inc. has identified a deviation that may cause the turn signal flashers to blink at a rate that is faster than normal. To resolve this, an update of the dashboard software is required. This software update solves the possibility of the turn signal flashers blinking too fast, particularly at low ambient temperatures.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
