P0300 issue -

[Steve_rayan]

Dears,

 

i have a 2018 Yukon SLE , last year on 20kkm suddenly the car starts vibrating hard and lose power and after this the engine alarm starts blinking along with the traction control for around 2 min then stopped.

 

the car kept behaving not normally as moving hard with bad noise and when you slow down it feel like something hitting the car from the back .

 

when it turn it off and ON the car become normal again!!!!

 

I submitted it to the local dealer and they dont know what to do as this issue showed three times .

 

Every time they come up with new issues.

 

Please i need your kind help if any one know what should i do .

 

Thanks
