A recent post on the Rav4World forum reports that some owners of Toyota Rav4 models are discovering an unsightly "melting" of their roof racks extending to vehicle roof trim.
OP lindaferiod is justifiably upset not only over the fact that her relatively new Rav4 is showing severe signs of what looks like melted and warping plastic on her Rav4's body but the fact that Toyota is refusing to warranty her claim because it does not cover "solar convergence.'"
A Summary Of the OP's Story
I purchased a 2024 Rav 4 hybrid in November 2023. I loved the car the first few months I owned it, but then my Rav4 started to melt within the first 5,000 miles.
The dealership I purchased the car with said it was due to solar convergence, and it was not covered.
The OP was surprised by this because she lives in the Northeast, where the winters are cold and not particularly sunny, and has kept her Rav4 parked in her garage.
I went to a different dealership, and they replaced the racks last fall…now the new racks are melting, and the plastic piece above the back window is melting.
Here is What the Damage Looks Like on Her Car:
I can't imagine how much my car will melt this Spring or Summer."
Solar Convergence in Modern Cars
Solar convergence damage in modern cars refers to a phenomenon where sunlight gets focused through curved or angled glass surfaces, like windshields or rear windows, and concentrates on interior parts, causing localized heat damage.
So hot, in fact, that it can melt or warp plastic trim, discolor or scorch leather or fabric on dashboards and seats, and even cause cracks in displays or infotainment system screens.
In short, it is a magnifying glass effect happening inside your car.
But how is this happening outside of the vehicle?!
Others Report Outside "Solar Convergence" Damage
As it turns out, the problem of "solar convergence" claimed by Toyota is not limited to some Toyota models but also to other makes and models.
And it is also happening to the outside trim and body areas of the vehicles.
- In San Antonio, Texas, a woman discovered that the rear end of her Toyota Prius had become wavy and distorted.
- A 2022 Toyota Corolla Hatchback owner noticed the plastic on the passenger side mirror warping and separating.
- Owners of Toyota RAV4s have reported melting and bubbling on rear spoilers and door moldings.
In all 3 cases, the cause was attributed to solar convergence caused by reflections from nearby modern building windows.
Social Media Posts Claim It's Not Solar Convergence and Wants Toyota to Own Up To It
From the forum thread posts, we can see that not everyone is buying Toyota's "Solar Convergence" theory and is blaming it on Toyota resorting to cheap plastic parts, which is a problem with all manufacturers of modern-day cars.
The thread post makes a good point and demonstration of it. Others, however,state that solar convergence is possible, but that Toyota needs to have concrete answers about why exactly it happens to some Rav4 owners and not others:
Still, we can understand why Toyota owners are upset. As the OP points out, pinning the cause on cheap plastic is more believable and may be a good reason not to buy a Toyota until this question is satisfactorily resolved.
Toyota knows they are using cheap plastic on their cars and that is why on my bumper to bumper warranty they exclusion solar convergence. I purchased Honda's for 20 years what was I thinking buying a Toyota. Never Again!!!!
Tell Us What You Think: Is solar convergence real, and is Toyota in the right in denying warranty coverage? Or do you feel that Toyota is trying to weasel out of any responsibility?

Toyota is not the quality car it used to be. Avoid buying the hype. Move on to quality. The company is making decisions like Kodak, and they're headed for the same fate.

I have seen numerous examples of plastic items, in the same packet or on the same gadget, being slightly different colour or more/less brittle. The obvious reason is the lack of rules and regulations in the producing countries regarding the 'recipes' used to create the plastic.

solar convergence is as real as water freezing during the winter, that's why car manufacturers don't use pure water in the engine cooling system but special coolant that does not freeze. If the sun or heat is a problem to some components the car manufacturers ARE responsible for finding solutions to avoid the problem. Yes this must be covered under the warranty as this is not "wear and tear" thing. The breaks will worn, the tires will worn but that's their job, do it's maintenance thing. The body or the internal parts of the car should not melt, that's not their purpose. Any claim of "solar convergence" is just bs. It's like saying "your cooling system broke from cold weather? Not our problem we filled it with water it's "cold water convergence" haha come on Toyota!

Thanks for the review. I have owned Toyotas 2006 Sienna, a great car for 250,000 miles on it. Finally traded it for a Lexus GS 350 amazing car. I have been shopping for a RAV 4 for my daughter but this quality problem has me considering other brands. Toyota is struggling with engines that fail often a in a terrible way, and the meltdown is not widely advertised. Their reliability and cooked up warranty excuses will hurt them a lot. Once again thanks!

This has been discussed in the Honda Civic Type R forums, too. Owners report various trim pieces getting wavy or distorted, and Honda says it must be because of sunlight reflected off skyscraper windows or similar while parked outside. So the car manufacturers are brushing their hands of climate change impacts.

Funny thing is this doesn't happen on my older Toyotas, that are kept in the same conditions, same climate, and make the same darned commute 12 months a year. My 2014 Camry doesn't melt, my 2009 Venza doesn't melt, my 2005 Matrix doesn't melt, but my 2024 RAV4 melts, as does our 2023 Corolla. So Toyota is cheating customers by denying these warranty claims. They used to be reputable, but now they're no better than American cars.

The solar convergence theory is beyond bizarre - if that was real then every car in south Florida would be melting like the wicked witch of the west- it is obviously a material quality issue and unless Toyota can demonstrate that a particular car was parked outside at a particular time and place where solar energy was concentrated beyond what a manufacturer could reasonably expect (and design) then they should pay

I read the Rav 4 owner about cheap plastic parts warping( or whatever you want to call it) Other Toyota owners as well & Toyota won’t own up to it? What happened to Toyota reliability? No guts & taking no responsibility. I’m not much for government overreach but perhaps the US Government should do something about this. Shame on the Toyota family & TMCorp., of Japan for this.I have had 2 with few issues but this Unacceptable. At least Ford, as far as I have experienced takes responsibility, even if they are the leader in recalls.

Having been with Toyota for over 27 years in dealerships, this warrants an escalation up the ladder.. the service department should contact their factory rep, the DPSM, District Parts and Service manager. They can approve these type of claims, paint claims etc. Toyota doesn't want to lose customers over something so small.. Especially if they have bought multiple Toyotas or do their service with Toyota. It would be almost impossible to prove Solar BS. I'd be shocked if they did not approve it.

We should all lease vehicles and let the " solar convergence" happen on the used car lots. I'll bet they'd resolve the issue then. Absolutely ridiculous

The wild thing about this story is I sold the Prius about 6 years ago that the story has a link to, I talked to the service department to try to get them to fix it, they broke down how the new energy efficient windows can turn the sunlight into a basic laser beam, and it wasn’t a factor of cheap material but unfortunate natural phenomenon. I said can’t we help and they said imagine if we helped every Flood victim, every car caught in a fire in a home, every car hit by a meteor. I never heard of it again until this story, so it caught my eye and sure enough Melissa’s story was right there for me. Such bad luck for such good people.

I bought a 2015 Toyota Corolla le in 2017. 32,000 miles. Very good car. My 3rd Toyota. Pearl white paint started peeling from trunk and cab last week in Feburary 2025. Took to Toyota Dealer. Recall on paint expired FEBRUARY 10 2025. TWO weeks before. Never received warranty recall? Only happens on white paint? Nothing Toyota can or will do. Planning on buying another Toyota. Not now. Quality getting bad.

Warranty means nothing. If the vehicle is quality, stand behind it. Rust is a major problem, they will never warranty. Cheaply built

You can bet if we sold a Toyota dealership window glass for the front of their dealership, and it started melting, they'd expect it to be replaced, warranty or not. Same principle - passing off terrible materials.

This just sounds horrible!!! If they are using cheap plastic or not, they should 100% cover it!!! We just leased a Toyota RAV4 in June 2024. If this ever happens to us, and they don’t do anything about it, I would definitely never buy a Toyota again. That is just horrible. We have a 2011 Hylander as well as the 2024 RAV4. I am so glad the RAV4 is leased because if we ever notice anything like that happening, we will be switching. Such a shame because my husband and I are so happy with our Toyota’s.

I had a Toyota RAV4 that started having transmission problems. So I took it to a mechanic and they rebuilt the transmission. After, same issue numerous times after that. Turns out, it was the vehicle's computer that was failing. So I spent the money to have it replaced.
A year later, I get a notification in the mail about the vehicle computer recall. I submitted my receipts and everything to Toyota. They denied my claim because I was 200 miles over the warranty limit.
I will never buy from Toyota again.

I encounter thousands of vehicles annually. Yes, Toyota / Lexus vehicles do have "melting" dashes, bumpers and other plastic components. It si similar to the old Shrinky-dinks childrens plastic toys of the 1980's. It may even be the same manufacturer.
There plastic components also cannot cope well in cold weather climates. This is why the door handles break when operated in cold environments.
