A crack in the manifold.
The electrical motor of one window is broken.
More than 12 liters of petrol on 100km.
Speedometer sometimes is stuck on 0.
These problems all occurred in less than 1 year. For me this is a sign of low quality.
When I drive in the mountains, my Leganza feels like a heavy stone. I always have to shift to a lower gear. This was not the case with my Accord which was 10 years old.
I drive not too fast, and still the engine uses more than 12 liters on 100km. My Accord only used 9.5 to 10 liters.
I already had more problems with the Daewoo in 1 year than with the Accord in 10 years.
I went to daewoo because of the price, but that really was a mistake. It is still too expensive for what you get.
