Engine Failure with Less Than 300 Miles

Bough brand new 2021 Kia K5 GT (not the GT Line). With LESS THAN 300 MILES and after owning for only 3 weeks the engine light came on and the car started shaking violently. Car has been at dealer for 5 WEEKS and they still do not know issue. Kia stonewalling on replacement or refund. Apparently engine issues are still a problem for Kia.

K5 GT line so far so good

Quite pleased with the 2021 K5. New owner and never purchased a KIA before. The looks styling and even the overall performance not to mention price point all came together to have us purchase this car. I am surprised that it’s as long as it is (8 inches longer than my Tesla Model 3) but it doesn’t feel “big”. Happy with performance and ride. I do not expect Stinger performance and as long as you have realistic expectations the vehicle will drive amazingly well and perform. We have the GT line with the 18” rims and it corners as good as a BMW 3 or 4 series.

This car is a kick in the pants!!

This is the first Kia I've owned and so far I'm not disappointed! It has all the bells and whistles plus some things I never knew I needed!
