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.

From owner reports, verbatim

When throttle gets wet, it will cause the engine rpm to drop dramatically or even stall. You have to come to a complete stop, shut off everything including key and kill switch, then restart. KTM is aware of this but has delayed for several months sending out replacement parts even though they sent a letter notifying me that it was a recall. Your system doesn't show any recalls when there is. KTM needs to send out parts now and your system needs to acknowledge and list this recall.

Too few reports in this category for a page of its own — they appear in the full complaint list.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
