been driving the swift for almost 2 years now. Zero complaints so far....
to clarify a few things, it does not contain japanese parts. However, it is one of the few cars available in Pakistan that have high number of CKD parts..in other words, most of its parts are imported. the parts are usually thailand.
about your problems, i would recommend to change the dealership and get a thorough inspection. maybe it requires a few bolts tightened here and there. belts tension can be sorted out anytime.
a word of advice. always keep it maintained from a good reputed dealership. one of the benefits of owning a PKDM is the peace of mind that you always have access to expert technical support and genuine parts. strictly follow the recommended maintenance schedule and Inshallah your car will never give you problems.
