Misfire engine

Asset · Nov 9, 2024

I have Thoe 2018. Today in the morning, check engine start blinking and ABS is off. I can feel the car is vibrating pretty bad, even when car is not driving.
Went to dealer and they check codes. Find out that engine is misfire and something wrong with cylinder #6
When i was driving the car was shacked as well.
How serious it is? they say that it takes 3-5 days for diagnostic, but i just want to be prepared.

It should not take 3-5 days for diagnosis, and the cause can be from many sources. The use of a quality bi-directional scanner should be able to locate the source of your issue in a matter of hours.

could be anything from simply needing a induction service, spark plug, coil, injector, to internal engine damage.
without checking it out thoroughly it's just a guess

Hopefully it is simple. He said the same thing. Can be serious or not , diagnostics will help. But why car is shaking?

the engine runs smooth with all 8 cylinders firing, when 1 is missing, it's like a table or chair with 1 leg shorter than the rest so it wobbles
same thing applies for many moving things like fans, unbalanced wheels, drivelines, all kinds of things basically anything that spins has to be balanced.

Got update from dealer, i don't know details, but basically, they are saying that need new engine. They said something with drive shaft in cylinder #6
NEW ENGINE with 80K miles. Are you kidding me??

it might be worthwhile to get a 2nd opinion from a different shop, dealers tend to not want to make repairs and instead want to just replace it.
