they wont change the whole car ler. but changing to a new engine is not impossible, but very possible.

when i bought my PE, i have the same problem. sent to SC, and after diagnosed, the solution is to replace the engine. so they have to order from the factory. no need to go through jpj again since they will stamp the same engine no on the new engine block, straight from factory! but you have to bear wasting your time again. it took me about a month before i could use my newly bought car again
!

p/s: even if you go to the tribunal, even they would say that u wont get a new car, since all car companies provided warranties for their cars. unless they do not honour the warranty/refuse to replace/repair the faulty parts, then you may got yourself a case.

so, just bear with it. once u got the new engine, you'll be smiling again

this.
you cant stop the payment once you SIGN the Hire Purchase agreement the day you receive your car! that's why it's important for you to check your car carefully before you agree to accept it. if you dont sign, the bank will not make any payment to the seller! once you're sign, bank paid seller, you pay the bank, there is no turning back. whatever problems arise with the car is not the bank problem anymore, but it's between and the SC.

just sharing my experience
