This report has collected data from vehicles whose warranty has expired i.e. Vehicles from before 2017 as peugeot provides 3yr warranty in UK. Peugeot's latest crop of vehicles began with the 3008 that went on sale in Jan 2017.
Regardless of all that, the rating is 13 out of 30 car companies with many big names sitting below Peugeot. Moreover, here's what this report states:
"Another brand that does fairly well for reliability according to Warranty Wise is Peugeot. A 64% overall rating is fairly decent in this company and, based on the warranty repair claim data, Peugeotâs donât tend to cost too much money to bring back into full working order."
I don't get how you summarized this as "not good"
None of the "reviews" you have cited are of any modern Peugeot and most of their arguments are based on the recycled "French car=unreliable" trope that is old news in 2021.
