Toyota Prius Defect Class Action Overview: 

  • Who: Toyota has been hit with a class action lawsuit over an alleged defect in its Prius HVAC systems.
  • What: Drivers allege that the defect fills cars with “an overpowering urine smell” or one comparable to “a pile of rank, sweaty socks.”
  • Where: The class action is for drivers nationwide.

An HVAC default in some Toyota Prius models has filled cars with “an overpowering urine smell” or one comparable to “a pile of rank, sweaty socks” due to noxious fumes being released, a new class action lawsuit alleges.

The class action was filed in California on Wednesday by lead plaintiff James Bettles who alleges that Toyota and affiliates knowingly sold the defective cars, failed to warn consumers about the issue, and then refused to fix the problem – violating state and federal laws.

Bettles purchased a new 2016 Toyota Prius in December 2016 in Sacramento and by spring of 2017 he began noticing a foul odor emanating from the air-conditioning, the claim explains.

“At first, Plaintiff thought that the odor was being caused by the shoes and socks he was wearing, and proceeded to wash his socks for several cycles to make sure they were clean, and thereafter purchase new footwear,” the claim reads.

“The foul odor persisted, however, and, in fact, became worse as Summer 2017 approached.”

Despite taking the car back to the dealer twice and discussing the smell he was either dismissed or told there was no fix for the issue and he had to either become more tolerant or do insufficient fixes, such as use air freshener, the lawsuit explains.

Toyota Prius HVAC Defect Causes ‘Moisture,’ ‘Mold’ To Accumulate 

According to the lawsuit, 2006-2020 Toyota Prius, 2017- 2020 Toyota Prius Prime, 2010-2015 Toyota PHV, 2012-2016 Toyota Prius C, and 2012-2017 Prius V all have an identical and inherent design defect in the Heating, Ventilation, and Air Conditioning (HVAC) system. The defect allows moisture and microbial growth to accumulate in the HVAC system causing it to emit foul, noxious, and toxic odors into the passenger compartments.

This then exposes those in the car to a safety risk from the mold and other contaminants that are emitted in the air circulated through the HVAC system, the lawsuit alleges.

Bettles describes one driver saying the odor was “an overpowering urine smell coming out of the vents,” and smelt like “somehow an animal must have gotten into the engine, urinated and the urine and bacteria has built up somewhere in the car.”

Bettles himself said the odor was like smelling a “pile of rank, sweaty socks.”

Despite Toyota being fully aware of the issue and releasing numerous Technical Service Bulletins to its network of distributors and dealerships describing the foul odors, the company continued to mislead consumers about the cars as it “actively, and affirmatively omitted and concealed the existence of the Defective HVAC System to increase its profits by selling additional vehicles and charging consumers for special filters, HVAC servicing, and other ‘repair’ fees,” the claim alleges.

“Additionally, Toyota has refused to issue a recall and has not remedied the Defect and/or compensated Plaintiff or Class members for their damages resulting from the material Defect.”

Bettles wants to represent Prius drivers nationwide and a Class of California drivers. He is suing for fraudulent concealment, unjust enrichment, breach of warranty, and violations of the Magnuson Moss Warranty Act, California’s Unfair Competition Law, California’s Consumers Legal Remedies Act, and California’s Song-Beverly Consumer Warranty Act. He seeks certification of the Class, declaratory relief, damages, restitution, reimbursement, interest, legal fees and costs, and a jury trial.

    I have the same issue it smells like rotten urine. I own a 2016 prius. I have had a weird cough for over a year. Never had respiratory issues before. I wonder if that is why

  2. Kevin Mastronardi says:

    I have charcoal bag aur freshener. I have essential oil sprays, fabreze, you name it. I wash and vacuum car almost every day. I drive Uber and I am afraid to buy another Prius.

  3. San Man says:

    I have a 2015 prius. I smelt rotten egg smell. I purchased BG frigiclean on amazon and went ahead and squirted it up the drain tube from bottom of car. I saw you tube videos before doing this. Then I sprayed the air vent refreshing spray in the air intake. Smell has gone I believe but I also did not notice much dirt coming out from drain tube. The AC evaporator core was not that dirty after all (water that drained was quite clear actually) unlike my 2004 honda odyssey which came out dark black!!!
    I also changed my cabin filter afterwards.
    I no longer cough much when sitting in my car like before.
    I still smelt a rotten egg smell vaguely after this…..but not much. Is it coming from the cars hybrid battery?
    Toyota definitely needs to address this issue.
    So many complaints.

    My prius smells like mold.

  5. stacey smith says:

    I have a 2011 Prius and have had this awful urine, musty smell for months now. i thought maybe a mouse crawled into my car and died but we have torn my car apart and have cleaned and cleaned, nothing helped. i even but a Ozone machine in overnight and that didn’t help. i would love to get in on this class action! i cant even drive my car its so bad i get headaches nauseous within minutes!

  6. Wade Bakken says:

    I have a 2007 Prius that my work partner describes as “stinky old man smell” or “someone pissed in here”. It’s a horrible “body odor smell”. When we drive he has to roll the window down with his head sticking out. Today he said he will never drive in that “shit diaper again”. He was retching before we had driven for 10 minutes. I have been mortified and ashamed that my car stinks. I’ve cleaned my clothes, cleaned the car multiple time and sprinkled boxes of baking soda on the carpet. I’ve sniffed every square inch of the carpet and seats, puzzled that I could not find the “spill”. On a whim I googled “stinky Prius” and found an abundance of people reporting the same thing!
    I am really angry at the emotional toll this has taken on my friend and I, and not to mention the 50 hours trying to correct the problem. Add on keeping two cars insured because some people won’t ride in the Prius and the dozens of hours cleaning my clothes. I’m angry that Toyota didn’t own up to this and save people a huge amount of suffering and misery. We are social creatures and being smelly is really shameful and depressing. Sign me up, we will drive to California to testify. (Not in the Prius)

  7. CANHUI HUA says:

    My 2006 Prius smells like this too, damn Toyota

  8. Kay says:

    I thought it was just me !!!!

  9. Phesk says:

    I’ve been dealing with this since we got our used 2019 Prius Prime last year. Sprayed and shampooed all the upholstery, emptied several cans of lysol into the ac over the last 12 months.
    Now I can tell my wife I’m NOT crazy after all.

  10. Wendy says:

    My 2005 Prius smells terrible, I had it detailed twice, ran Lysol through the air intake among several other things to try to get the smell to go away. We don’t even drive it anymore because it smells so bad. I opened the windows and put it in the garage and the entire garage smells from it. If this is a defect I’m extremely disappointed in Toyota, we have owned several Toyotas and never had this issue. I smell like the car when I try to drive it, clothes, hair, everything. Disgusting and frustrating!
