What's Causing the Rotten Smell in Some Hyundai Palisade SUVs?

A persistent, foul odor described as resembling rotten produce or a locker room has emerged as a significant issue in some 2020 Hyundai Palisade SUVs, according to long-term testing by automotive experts. This problem, which has generated considerable attention from owners and media alike, has so far proven difficult for dealerships to resolve with conventional cleaning methods. While the exact cause remains under investigation, the situation highlights the importance of thorough pre-purchase inspections for used models.

What Is the Hyundai Palisade Smell Issue?

The issue involves a mysterious and potent odor that develops inside the cabin of certain 2020 Hyundai Palisade SUVs. Owners and testers report a smell akin to decomposing food or mildew that permeates the vehicle's interior. Despite attempts at remediation, including a head-restraint replacement and specialized upholstery treatments, the odor has proven stubborn. Based on our assessment experience, such problems can often be traced to contaminants in the HVAC system, spilled liquids seeping into sound-deadening materials under the carpet, or issues with organic-based adhesives used in the interior assembly. The challenge lies in pinpointing the exact source, as the smell can migrate throughout the cabin.

How Does This Affect Potential Palisade Buyers?

For shoppers considering a used 2020 Palisade, this odor issue is a critical factor to check for. A foul smell is not just a nuisance; it can indicate the presence of mold or bacteria, which could pose air quality concerns. We recommend a thorough interior inspection and test drive of any specific vehicle you are considering. Pay close attention to the air conditioning output when you first start the car and check for any dampness under the floor mats. It's also advisable to search online for service bulletins or owner forum discussions related to the VIN (Vehicle Identification Number) of the car you're looking at. While not every 2020 Palisade is affected, due diligence is essential.

Beyond the Palisade investigation, recent automotive news covered several other significant SUV reviews and updates, offering alternatives for buyers. Key stories included:

What Should You Do If Your Car Develops a Strange Odor?

If you encounter a persistent bad smell in your vehicle, whether a Palisade or any other model, systematic troubleshooting is key. Start by eliminating simple causes:

1. Remove and Clean: Take out all floor mats and clean them thoroughly. Check under seats and in cargo areas for forgotten food items or spills.
2. HVAC System Cleaning: Replace the cabin air filter—a simple and inexpensive maintenance task. Use an HVAC system cleaner spray designed to kill mold and mildew in the vents.
3. Professional Detailing: If the smell persists, a professional interior detail that includes shampooing carpets and upholstery may be necessary.
4. Dealership Service: For new or certified pre-owned vehicles under warranty, contact the dealership. Document the issue clearly and request a comprehensive inspection.

A persistent interior odor in a car like the Hyundai Palisade is more than an annoyance; it can be a sign of a deeper issue that requires professional diagnosis. For potential buyers, a meticulous inspection of any used vehicle is non-negotiable. For owners experiencing the problem, a methodical approach to cleaning and seeking professional service is the best course of action. Always research common issues for any specific model year and have a used car inspected by an independent mechanic before purchase to avoid unexpected problems.
