Opel Mokka 1.4t Cosmo - disappointing

I am so disappointed in the Opel Mokka and would not recommend anyone to purchase it as it seems that as soon as the service plans expires all the problems starts creeping up. This is my second Mokka on 93000km and giving me the same problems as the previous model. The car will start jerking randomly and it is such a risk to drive. I am just despondent at this stage as I know how long it was a struggle to convince them that there was something wrong on the car and to have the engin replaced. Opel, please sell us products worthy to purchase that we will happily pay for, a very annoyed me...
