Loss of power to engine when trying to increase speed to turn into traffic/getting onto the highway and constant severe engine knocking noise. I have to use hazards when turning into traffic/merging onto highway because the vehicle takes too long to catch up with the speed of traffic. It also has a problem with excess oil consumption, needs to be refilled every week and a half to two weeks. Bremerton transmission has provided an inspection and a diagnostic trouble code (dtc) p1326 (knock signal range/performance). The oil consumption has been an ongoing issue since i bought the car in february of 2022, only getting worse. The rest of the issues have been escalating problems.
