I have a 2015 Hisun 400hs that jumps out of forward. tried adjusting linkage but didn't take care of it. Took it to dealer bought it from but they were no help. All they said it was internal and wanted $1000 labor. I have less than 100 miles on it. Only owned it 1.5 years. It was ahold over from 2015.

Can anybody give me some infro on this problem
