Another good one that might be a bit more familiar to students might be the rollover crashes of Ford Explorers that were reported to the media to be due to Firestone tires rather than tire pressure, and how it created a stigma against Explorers such that Uhaul would not rent trailers if they were to be towed by an Explorer but had no restrictions against Mercury Mountaineers which were built on the identical chassis. Ultimately Ford re-engineered the suspension to claim the issue had been addressed.
