Same thing happened to me. Less than 200 miles on a 2025 TRD Off Road. It is starting to sound like a common problem, so I hope the dealers start keeping the parts in stock.

Okay, just following up. I took my 4runner to the dealership and they "gave" me a loaner while they checked it out. They ran a diagnostic on it and couldn't come up with any codes, so they had to open a case with Toyota USA (little worried). The next day they called me back and said it was ready to be picked up.
Apparently, the transmission was low on oil and that is what threw everything out of whack. Time will tell, but it still pisses me off that it gets out of the factory this way.

I’m having a very similar issue with my 2026 4Runner Trailhunter. My check engine light has come on four times already

My truck has only around 6,000 miles. The first time around 3500 miles, Toyota found an issue with the fuel vapor containment valve and replaced it under warranty. The problem came back, and during the third visit, my truck was at the dealership for about two weeks. They even opened a technical case with Toyota and eventually replaced the vapor pressure sensor.

Unfortunately, only about two weeks after getting it back, the check engine light came on AGAIN. I’ve also been experiencing excessive pressure when opening the gas cap.

My truck is now back at the dealership for the fourth time. Didn’t install any aftermarket stuff yet and haven't brought it to off road yet
