Rodents just can't resist the soy-derived wire coatings used in Kia vehicles. The chewed up wires are costing owners hundreds, and sometimes thousands of dollars in repairs. However, this isn't a Kia-only problem.
The most obvious benefit of coating wires in soy-based materials is it results in less plastic in the landfill or oceans. That’s a good thing!
But the coatings are a perfect chew toy for rodents, provide excellent nesting material, are are found in near endless supply in a warm, hidden spot. If you’re a mouse, it’s the greatest thing ever. But if you’re an owner waking up to a severed fuel line, it’s a little less enjoyable
Kia is not the only one to make this switch or deal with the rodent-problem
In January 2016, a lawsuit filed against Honda claimed the soy-based wiring was irresistible to rabbits. Later that year, a similar lawsuit was filed against Toyota. Both Subaru and Hyundai are also facing similar lawsuits.
