Need to replace complete belt tensioner & bracket assembly & serpentine belts. My concern is the plastic cracking in this assembly, the evaporative canister, also plastic is cracked and will be replaced also. Was there a bad batch of plastic used on these cars? cost to replace belt tensioner, bracket assembly & belts is approx. $800. 00. The canister is covered by kia - cost 164. 00.
