Wow, what a drop for Toyota. Regardless of your thoughts on JDPower, Toyota is hardly ever this low on any quality report.
The new Tundra and possibly the new Tacoma truck engines are killing Toyota. Take the trucks out of the equation and Toyota would be higher.
Surprised that Nissan ranks so high.
Not sure how meaningful these survey results actually are.
Nissan/JATCO CVT's have killed Nissan's reliability over the years. Lately, JATCO trannies have gotten better, bringing up the company's score.
As MrHorspwer said, the IQS isn't long term, it in the first 90 days of ownership and the complaints & fixes a customer experiences with their new vehicle.
For example, NISSAN is much higher right now however, when I bought my new 2015 Altima in 2015, I took it back 5 times for defects including poor paint quality and another 3 time for recalls and 1 time for a complete L & R rear control arms replacement under a campaign. So now, NISSAN is getting better with in house quality. But when it comes to long term quality/reliability, NISSAN is no HONDA or TOYOTA...generally speaking!
When we bought our new 2023 Toyota Venza Hybrid, it has a terrible paint job and the alignment was out of spec right from the factory.
And the infotainment system including the center dash screen info, often freezes. Other than those complaints, it's fine.
What all this means is, the rest of the world is catching up to one another in terms of assembly of their vehicles. It may not change the long term reliability which is engineering and using quality parts or not.
