So, surprisingly, I received a call from Peugeot Pakistan. A gentleman named Mr. Umar called me from Lucky's technical team and had a detailed discussion on the matter.
He explained to me that there is no inherent problem with the 2008's design or engine, and the air intake is high enough to avoid any rainwater in a normal situation. The cars that were damaged in this recent rain spell in Punjab all had signs of water flooding inside the cabin area, and some even had signs of engine bay flooding up to the battery holder, which means that some sort of negligence was shown by the drivers. He further added that all such owners who had insurance were compensated after due negotiations between the Lucky Motors team and relevant insurers to minimize the financial impact on affected owners. He insisted on the fact that this problem was not specific to Peugeot, as many other cars have been reported to have gone through the same issue in recent rains.
I hope that answers some questions. No matter what car it is, urban flooding can cause problems for all. The 8th-gen Civic was notorious for this issue, as I remember. That being said, I really appreciate Lucky Motors response to this whole thing and never really expected them to reach out to me on this issue, yet they called to explain the whole thing. I forgot to ask him about the timing belt issue tho.
