When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

The motorcycle becomes unstable and has a "death wobble". I purchased the motorcycle new from a Harley Davidson dealer and all service has been perform by the same dealer. The death wobble occurs at various situations including highway speed turns and straight high speed (~75-80 mph). This has occurred during calm and windy days. There was not rain and pavement was dry at the time of the incidents. The motorcycle continues to exhibit the "death wobble" at a variety of conditions not mentioned above, it is hard to guess when it will occur. I took it to the Harley Davidson dealer at ~200 miles and ~1,100 miles. The dealer reported that they could not reproduce the "death wobble". The dealer performed a test drive, checked the neck bearing, tire pressure and inspected tires. The "wobble" is not just an annoyance it is a true critical safety issue. I have also noted a significant number of other owners of the same motorcycle model/year have reported the same concern listed above. I urge the NHTSA to give a high priority in review of this safety concern. I have left the "Additional Details" section of this report blank as it occurred multiple times with the most recent being 8/4/2025 and the first being mid-May 2025. Basically, since I have owned motorcycle since new.

Harley redesigned their fairings on the 2024+ Street Glides, and have had issues with "death wobble" at higher speeds. When going down the Interstate at 80+ MPH, the bike has terrible front end wobble which you cannot accelerate or decelerate out of the wobble. You have to almost come to a complete stop before the death wobble goes away. I have taken the motorcycle to 2 different dealerships and neither one could duplicate the problem. These motorcycles are not safe at all! Harley needs to address this issue and come up with an actual fix for these issues.

VEHICLE SPEED CONTROL
The speedometer is off between 3 and 7 MPH, depending on the speed traveling. I took it in for service, and they stated they needed to consult with corporate. They never got back to me, and after a month, I reached out again, and they sent a text message stating the below: "David this is Jacob at Daytona HD. After speaking with Harley again on your speedo concern they consider it to be within acceptable range of being off. The ref # for the call is [XXX], if you would like to reach out to Harley regarding this the customer service phone # is 1 800 258 2464".

ELECTRICAL SYSTEM
I have my motorcycle setup to connect to my phone using Bluetooth. I used this to connect via Apple Car Play. I occasionally have an issue where my IPhone 13 Pro Plus screen goes black with a spinning wheel. The iPhone eventually restarts. This happens occasionally. I have heard other people in a Harley Facebook group complain about the same issue with their 2024 Street Glide and Road Glide.
