What vehicles dont have soy-based wiring?

Many modern vehicles use soy-based wiring, which is a more environmentally-friendly alternative to traditional petroleum-based wiring. However, there are still some vehicles that do not use soy-based wiring. This article will provide a detailed overview of the types of vehicles that do not have soy-based wiring.


Vehicles Without Soy-Based Wiring


Older vehicles, particularly those manufactured before the mid-2000s, are less likely to have soy-based wiring. Vehicles from the 1990s and early 2000s typically use traditional petroleum-based wiring harnesses. This is because the use of soy-based wiring materials became more widespread in the automotive industry in the late 2000s and early 2010s as automakers sought to reduce their environmental impact.


In addition to older vehicles, some high-performance and luxury vehicles may also not use soy-based wiring. These vehicles are often engineered with a focus on performance and durability, and the automakers may opt for traditional wiring materials that they believe are more reliable or better suited to the vehicle's needs.


Military and commercial vehicles, such as trucks and buses, are also less likely to have soy-based wiring. These vehicles are often built to more rugged specifications and may require wiring materials that can withstand harsher operating conditions, such as extreme temperatures, vibrations, and exposure to chemicals or other environmental factors.


Reasons for Avoiding Soy-Based Wiring


There are a few reasons why some automakers may choose to avoid using soy-based wiring in their vehicles:



  • Durability concerns: Some automakers may be concerned about the long-term durability and reliability of soy-based wiring, particularly in harsh environments or under high-stress conditions.

  • Cost considerations: The use of soy-based materials may be more expensive than traditional petroleum-based wiring, which could impact the overall cost of the vehicle.

  • Performance requirements: In high-performance or specialized vehicles, automakers may prioritize wiring materials that can better withstand the demands of the vehicle's operation, even if they are not as environmentally friendly.


Despite these concerns, the use of soy-based wiring in vehicles has become increasingly common as automakers strive to reduce their environmental impact and meet consumer demand for more sustainable products.

Which cars do not use soy-based wiring?


It is nearly impossible to find a car that does not use soy-based wiring, as the vast majority of major auto manufacturers have used it since around the early 2000s due to environmental regulations and cost-effectiveness. This includes manufacturers like Toyota, Kia, Hyundai, BMW, Audi, and others. 

  • Widespread adoption: Due to its environmental and cost benefits, soy-based insulation became a standard practice for most manufacturers starting in the early 2000s. 
  • Common brands: Manufacturers that use soy-based wiring insulation include Toyota, Kia, Hyundai, Nissan, BMW, Audi, and many others. 
  • Problem for consumers: The use of soy-based wiring is often blamed for problems with rodents chewing through wires, as the insulation is palatable to them. 
  • No known exceptions: It's not possible to name a car that definitively does not use soy-based wiring, as the practice is so widespread across the entire modern automotive industry, according to this Reddit thread. 



Does Honda use soy wiring?


Yes, Honda has used soy-based wiring insulation in many of its vehicles, which has led to problems with rodents chewing on the wires. While this was intended to be a more environmentally friendly option, its soy content attracts pests, and the company has faced lawsuits over the issue. Honda has also started selling special "rodent tape" to protect the wiring from damage.
 
Key details

  • Soy-based insulation: Honda has used soy-based materials as a more environmentally friendly alternative for wire insulation. 
  • Rodent attraction: The soy content in the wiring has been reported to attract rodents, causing them to chew on the wires and leading to vehicle malfunctions. 
  • Lawsuits: Class-action lawsuits have been filed against Honda claiming that the company knew about the problem but did not cover the damage under warranty, instead suggesting customers purchase special rodent-deterrent tape. 
  • Solution: Honda has released and sold a "Genuine Honda Part" called "Rodent Deterrent Tape" to help protect the wiring. 
  • Industry trend: It's worth noting that many modern car manufacturers have switched to soy-based wiring, and rodents have been known to chew on wiring for years regardless of the material. 
  • Legal outcomes: Despite the lawsuits, courts have dismissed them due to a lack of evidence that soy-based wiring attracts rodents more than traditional petroleum-based wiring. 



Does Toyota have soy-based wiring?


Yes, many Toyota vehicles, particularly those from approximately 2008-2016, have been reported to use soy-based wiring insulation, which can attract rodents. This issue has led to lawsuits against Toyota and other manufacturers and is a common concern for many car owners. 

  • Common models affected: Vehicles like the Camry, RAV4, Tacoma, and Tundra have been cited in reports and lawsuits. 
  • The problem: The soy-based insulation is attractive to rodents like rats and squirrels, who chew through the wires, causing extensive and expensive damage. 
  • Manufacturer awareness: While manufacturers claim the issue is a result of using environmentally friendly materials, they have also been aware of the problem, with some models reportedly receiving wiring that is treated with a rodent-repellent tape. 
  • Recommendations: To protect your vehicle, mechanics recommend avoiding parking near tall grass, moving the car regularly, and using rodent repellent sprays or other deterrents, though their effectiveness can vary. 



Does BMW have soy-based wiring?


Yes, many modern BMWs and other car manufacturers use soy-based or bio-sustainable materials in their wiring insulation, which can attract rodents. This has led to frequent reports of pests chewing on BMW wiring, sometimes causing costly damage. 

  • Reason for use: Car companies adopted this practice to create more environmentally friendly, biodegradable parts. 
  • The problem: The soy-based insulation is edible and appealing to rodents, such as rats, mice, and squirrels. 
  • Consequences: This can result in damaged wiring harnesses, leading to vehicle malfunctions and expensive repairs that are often not covered by warranty. 
  • Manufacturer response: While the practice is common, many owners have reported a lack of corporate support when dealing with these issues.
