  • Auto Correct | Flood Vehicles "Hurricane Katrina @ 20"

    45:39|
    A flood vehicle, or flood-damaged car, is a vehicle that has been partially or fully submerged in water, leading to significant and potentially hidden damage to its body, engine, and electronics. These vehicles often receive a "salvage" or "flood" title, which should be disclosed by sellers. Hurricane Katrina flooded and damaged an estimated 500,000 to 600,000 vehicles along the Gulf Coast, with about 300,000 vehicle insurance claims filed due to the storm. Efforts were made to identify and destroy these water-damaged cars, but thousands still resurfaced on the used car market, sometimes with hidden damage.Email the show: auto@mpbonline.orgRecalls: Check for Recalls: Vehicle, Car Seat, Tire, Equipment | NHTSANews: What Is Hydroplaning, And What Should You Do If It Happens?Auto Casey Car Review: 2026 Subaru Solterra | Short take

    Chevrolet, often called Chevy, is an American automobile brand and a division of General Motors (GM). It's known for its wide range of vehicles, from subcompact cars to medium-duty trucks. The name "Chevrolet" is also a French surname, originally referring to a place where goats were raised. The brand was co-founded by Louis Chevrolet, a Swiss-American race car driver, and William C. Durant. Chevrolet and GMC are both brands owned by General Motors (GM). While they share some similarities, GMC is generally positioned as a more premium offering than Chevrolet. Both brands offer a range of vehicles, including trucks, SUVs, and crossovers, but GMC often includes more upscale features and finishes.  Recalls: Check for Recalls: Vehicle, Car Seat, Tire, Equipment | NHTSANews: Amtrak's new Gulf Coast line will start service in AugustAuto Casey: 2025 Chevrolet Silverado EV | Short TakeEmail the show: auto@mpbonline.org
