I bought a 2017 Spark LT about 6 weeks ago and the rear wiper just sucks. It's only wipes in stripes so it's pretty useless as it stripes are so small it's like it didn't really do anything. I have been to 7 different auto stores near me, 3 different companies, and none of them had a part for me. One of them said the only non OEM part is the Bosch H230.

However I saw on other forums that previous year models were having issues with the replacements not contouring to the curve of the window. The only one that I saw that the majority didn't have issues with was the Michelin 9512, but the interwebs says it won't fit my model. I haven't been able to find a forum for the 2016+ models about the rear replacement.

So my question(s), is the Bosch my only option outside of going to the dealership for a replacement? And is it going to actually work and be worth replacing? Or would I be better off paying a ton for the dealership OEM?
