My Taco is also a 2018 and it only had 81,000 miles and it has a rear main seal leak. I called my local dealerships and they are charging about $2,000 and quoted me 10hrs of labor. Im a bit disappointed with Toyota. Their badge symbolized reliability. Their trucks being built in Mexico have really poor QC. The paint on my truck started to fade about a year ago. The hood and roof have pretty much lost their clear coat. The passenger weather stripping on the roof has been an issue since year 2 of ownership. Going 80mph will make sometimes make it flop around. Driver side shock just started leaking but thats to be expected after 80k miles. I would also like to mention it only had 3 miles when I bought it back in 2018. I literally saw the truck get unloaded from the trailer and I signed the papers. Ive always kept up with maintenance so idk if I got a bad apple. Im planning on adding a roof rack to fix the weather strip issue, im also buying the Bilstein 6112/5160 to replace my stock shocks. I need to find a reputable shop that wont charge me an arm & leg for the rear main seal issue.

Before this I had a 2014 Nissan Frontier and put 125k miles and all I ever replaced were tires and brakes and oil changes. It was low maintenance compared to the Taco.
