“I received a notice on nov.05, 2018 harley davidson recall no. 0173 NHTSA recall no. 18v734. I went approximately on nov. 17, 2018 to drop off the motorcycle at one of the local harley dealerships in garland tx. And was told by one of the technicians that I would have to get on the list and that I would be called when it came my turn due to them not having the parts needed to fix the recall. I went back on 18th of dec. 2018 and asked one of the technicians if he had any idea on the wait and for the fix. He said he couldn't give me an answer. …”
