“My 2021 Acura TLX has a fuel leak. This is a known issue and manufacture design flaw. The Acura dealership has quoted my $4200 - $4500 to replace the fuel tank. I've contacted Honda and they've only offer $300 goodwill credit towards the repair. This is a know issue, a fire hazard, and other 2021 TLX has been recalled for this fuel tank/fuel leak issue via recall.”

There were no warnings leading up to this catastrophic fuel/engine issue. …”
