NHTSA Complaint #11552651 — 2017 KIA OPTIMA

Driving down the interstate, the vehicle started to decelerate and the engine light started flashing. Got it to a mechanic and he started that it was a knock sensor failure P1326 code. Same as the recalls, but my vin number was not included in the recall report. Already had this vehicle in for excessive oil consumption. Paid for the dealer consumption test. They said it only burned a qt. and that was acceptable. In 1000 miles. Have done my own 1000 mile test and have been burning 1.5 or more qts. on three separate tests. Something has to be done about these engines. This is dangerous when going interstate speed and dropping to 20 mph in heavy traffic.
