Many manufacturers have switched to these lightweight materials for fuel economy and corrosion resistance, creating challenges for magnetic car signs and vehicle magnets. If you're experiencing issues with car door magnets not sticking or magnetic decals for cars falling off, your vehicle likely has non-magnetic body panels. This is increasingly common as automakers prioritize weight reduction and durability. Vehicles with Non-Metal (Aluminum or Fiberglass) Doors/Tailgates
- Ford F-150 (2015–present): All major body panels – including doors, hood, tailgate and bed sides – are high-strength aluminum, shed 700 lb by using an all-aluminum body,
- Ford Super Duty F-250/F-350 (2017–present): All-new-generation Super Duty trucks feature a high-strength aluminum-alloy body and cargo box (doors, hood, fenders, bed and tailgate).
- Ram 1500 (2009–present): Aluminum hood (introduced in 2009) and aluminum multi-function tailgate (2019–present) (Other body panels remain steel.)
- GMC Sierra 1500 (2019–present, Denali/AT4): CarbonPro pickup bed (sides and floor) made of carbon-fiber composite. The CarbonPro bed is unique to Denali and AT4 models (2019+); the tailgate incorporates GMC’s steel MultiPro design.
- Chevrolet Corvette (C5/C6/C7/C8, 2001–present): Body panels made of fiberglass-reinforced composite (SMC) (hood, fenders, doors, rear hatch are non-metal). Corvettes have used SMC fiberglass for all body panels since 1973.
- Chevrolet Colorado: Body panels made of fiberglass-reinforced composite (SMC) (hood, fenders, doors, rear hatch are non-metal).
- Tesla Model S (2012–present): Bodywork (doors, hood, most exterior panels) is aluminum and thus non-magnetic.
- Tesla Model X (2015–present): Same aluminum-intensive body construction as the Model S.
- Land Rover Range Rover (2013–present): First SUV with an all-aluminum unibody – all outer panels (doors, hood, tailgate, fenders) are aluminum.
- Land Rover Range Rover Sport (2014–present): Aluminum unibody (similar architecture to Range Rover) – all body panels are aluminum.
- Jaguar XE (2016–present): Lightweight, aluminum-intensive sedan – most exterior body panels (doors, hood, trunk) are aluminum.
- Jaguar XF (2016–present): All-aluminum body (joined XE and XJ in Jaguar’s “aluminum-intensive” lineup).
- Jaguar XJ (2010–2019): All-aluminum luxury sedan – all main panels (doors, hood, trunklid) are aluminum.
Important Note for Magnetic Sign Users: Before purchasing magnetic car signs or car door magnets, verify your vehicle's body panel material. If the panel isn't steel, a magnet won't hold . This affects popular models like the Ford F-150 magnets market, Tesla magnetic signs, and truck door magnets for aluminum-bodied vehicles. For these non-magnetic surfaces, Signazon's reusable/removable car decals are the best alternative solution to traditional vehicle magnets.
