excerpt from the provided link: "Its showing in our 2019
Driver Power customer satisfaction survey is similarly reassuring, as the Kodiaq finished sixth out of the top 100 cars on sale. Owners love its engines, interior quality, ride, practicality and reliability, although electrical glitches were the most common problem within the 22.6% of owners that reported a problem in the first year of ownership.
Skoda came an impressive sixth out of 30 brands in our manufacturer list, although this is a drop from second place in 2017."
When you search for Peugeot 5008, you get this;

excerpt: "Peugeot came 12th out of 30 brands in our 2019 Driver Power customer satisfaction survey, beating the likes of Audi, BMW and Volkswagen.
Now, in fairness, a 12th-place finish isn’t that much to crow about, but it’s by no means a shocking result – and a marked improvement on Peugeot’s 17th-place finish in 2016. Given the 5008’s mechanicals are used by at least four different models of car, we’d say it’ll be as thoroughly developed as is possible."
So.. in short, (concerning reliability) Skoda Kodiaq 6th place, and Peugeot 5008 12th place.
