What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2015 Ducati Monster, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
The rear brake on my Motorcycle failed before 500 miles. The dealer had to bleed extensively. It failed again a few months later. The second dealer bled it but refused to submit a warranty claim. It failed again and was bled on two occasions and warranty claims were submitted and it was rebled on both occasions with replacement of the master cylinder. The dealer kept the bike for several months checking the rear brake while in storage but not running, and the brake remained functional. When I picked the bike up and started riding it failed once again soon after I got it, demonstrating it to be heat related. It failed again and a fourth dealer bled it. I was informed that the bleeding procedure had been incorrect. Once again the brake failed within a few months. A fifth dealer bled the brakes when it was just out of warranty as a courtesy customer service. The problem recurred leaving me with a the same problem. I bled the brakes three times, each time restoring proper braking function. Each time it failed and each time the reservoir was full of dot 4 fluid, but the line was full of air. I bled the brake elevating the caliper upside down per manufacturer protocol. Approximately 18 months ago I rebled the brake using Castrol React SRF fluid with a dry boing point of 620 degrees. I also put heat shielding on the brake line where it was exposed to heat from the rear cylinder exhaust manifold. The brake has performed correctly since the modification. No warning lamp came on. The cause of the brake failure has been consistent on this model regardless of the brake line part number and is the result of inadequate shielding and the need for fluid with a higher boiling point. My bikes line will have to be replaced with the new part with a metal line around the exhaust and the heat shielding replaced due to heat stress. Loss of any braking function is a serious safety risk.
REAR BRAKES HAVE COMPLETELY FAILED. FRONT BRAKE REQUIRES PUMPING REPEATEDLY. BOTH THESE ARE WELL REPORTED IN ON-LINE DUCATI MONSTER FORUMS AS RECURRENT AND DANGEROUS PROBLEMS. DEALER DECLINES TO REMEDY SITUATION OTHER THAN TO BLEED BRAKES, THAT ACCORDING TO FORUMS WILL RECUR. SOME FORUMS SUGGEST THERE IS A MANUFACTURER RECOMMENDATION TO REPLACE BANJO BOLTS WITH IMPROVED PART BUT NO REQUIREMENT FOR DEALER TOPERFORM THIS VITAL SAFETY FIX. THIS IS A SIGNIFICANT SAFETY ISSUE
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.
