Technically even Toyota Pakistan is incapable to manage Prius NEW parts.
All hybrids landing in Pakistan get support from Scrapyards. few people have started Battery Reconditioning based on manuals & technical skill . Batteries for Hybrid are Exchanged with OLD ones Reconditioned batteries are supplied to buyer in exchange at premium price.
skilled people exist to manage basic faults across Karachi however any Electrical Break Down or fault in synergy drive can only be removed through parts swap using scrap yards.
Karachi i can recommend Jamil Autos Shahrae Quaideen & Time Motors at Sharafbad near National college for Hybrids.
