12,134 miles on 2022 Taos. The check engine light, the EOC light came on, and the car went into limp mode with 4,000 a RPM limit. The dealership said it was because I did not have the oil dip stick in all the way. I have a lot of experience with cars, Army tanks, and RVs. I know how to check the oil. That was when the argument started. LOL. So, the dealership reset everything, gave me a free car wash, and the Taos was just fine for about 1200 miles on a long road trip. The check engine light came on again. I pulled into a Loves Travel Stop and checked the oil. It was OK, the oil level full, and the gas cap was on tight. I had not "topped it off" or anything. The check engine light did light not go out. But, I did get it to go out. Here is how: I started the car and with the engine running, I pulled the dip stick out twice and and reinserted it while the engine was running. The engine makes a sucking air sound without the dip stick. If you look at the dip stick, there are two rubber "O-rings" where the dip stick seals the engine and prevents air from entering the dip stick tube. I turned off the car and waited about one minute. After restarting the car, the check engine light was out. I have driven over 1,000 miles since then and the check engine warning light has stayed out. My guess is that the O-rings must work together. Perhaps three O-rings are needed? I have an assortment of heat proof O-rings from Harbor Freight if it happens again. The other possibility is a N-80 module in the engine compartment gets clogged with oil and gas vapors and gets cleared when you pull the dip stick out, when the engine is running, and reinsert it a couple of times. I hope this helps because when you are on a road trip, it's hard to fund help. The Taos is a great car and I plan on keeping it. I put on my last car, 2010 Subaru Outback, 197,212 miles on it before I traded it in for the 2022 Taos. By the way, I know how to check the oil.
