I took my 2020 4runner TOR for its 32k KM maintenance to stay within warranty. I got home and the next day noticed a huge puddle of oil at the bottom of the garage. Looked at the skid plate and it's fully drenched and dripping in oil. Luckily i did not drive the car for long after oil change, waiting for the dealer to come fix it.

Did not get a CEL or any other warning... and refuse to turn the car on..... dealership is sending people to fix it..

Should i get a new engine? new car or extended warranty?

Simply unacceptable.

Your first mistake, taking it to the dealer. So many people here think “it was free so...” and end up with all these headaches.

Now a bunch of people here are going to show up and make moronic statements like “dealer should warranty you till one billion miles!” or “omg your engine is toast. I would demand a new Mercedes S550 and nothing less!”

What do you recommend....

I dont trust germans..... had 3 of them 2006-2010s...

What irks me is that they're supposed to be professionals....

Since a lot of the oil ended up on your garage floor, and you did not get a low oil pressure warning light, your engine will be OK; it had enough oil to make it home.

But what the dealer did is unacceptable. They use the lowest paid trainees to do the simple things like oil changes. A more senior tech should have checked the tightness on the oil filter and drain plug before returning the car to you. You should definitely make a ruckus with the service manager, and perhaps even the owner of the dealership.

The 2 most likely causes: pinched o-ring on the filter housing cap (I've had that happen twice on my VW Jetta) or failed drain plug gasket. Both easily fixed.

Other less likely but not uncommon causes: cracked filter housing from over torquing cap, stripped and loose drain plug from over torquing the plug. Unfortunately, both also totally plausible coming from a dealership service department.

There's nothing wrong with your engine. The oil warning light would have come on well before damage was caused. They're designed that way. If there is an abundance of oil under the truck on the garage floor it leaked out while sitting there overnight or however long you parked it. If you had problems you would have gotten them before you parked it.

I wouldn't run it. I would look for the source of the leak but I typically do my own maintenance so I tend to inspect things after someone else has worked on one of my vehicles.

As for Germam cars, IMO and experience they are reliable for the first 4-5 years. Then the problems start. I've been lucky with my Jetta, it's almost 10 years old and I've had no significant issues. I also think people tend to not be as diligent on their maintenance after the first 2-3 years so things can start to fail.

I can't agree with you more that the dealership is SUPPOSED to be the place with the professional experts that know how to work on the vehicles they sell BUT the truth is dealerships tend to hire new mechanics fresh out of school who have been trained on how to plug in a diagnostics machine and press some buttons. They are not top of their class mechanics and they don't put an emphasis on how to actually do quality, detail oriented mechanics (i.e. wrench turning). They are paid as little as possible and only when they are actually working on something so the process then becomes quantity over quality, push as many jobs through as they can. The details suffer, things get missed and stuff like what your are experiencing happens. I'd wager that you'd be hard pressed to find a mechanic at a dealership with more than 5 years experience working there. If you did, they're probably the senior person on the shop floor.

I understand that not everyone has the skill, time or desire to do their own maintenance and that's ok. It's not for everyone. What I always recommend is finding a quality, small, independently operated shop that can handle your maintenance. They keep records and Toyota cannot void your warranty for having your maintenance done and documented somewhere else unless they can prove without a doubt it was done improperly. Improper maintenance happens far less at small shops because the mechanic working on your vehicle is often the business owner and cannot afford for the work to be done wrong. Their livelihood is at steak so they pay attention to what they're doing.

Some of this is assumption based but most of it is experience over a few decades and a lot of different makes/models of cars and trucks. I stopped going to dealerships for anything other than recalls or warranty work and even then, I try to avoid them.

You should be okay. As others have mentioned, start doing it yourself. I had an issue one time with a Lexus dealer (overfilling) and I have since done all my own work.
I would suggest getting a fumoto valve as it makes it so much easier and CLEANER when draining the oil, especially when using a hose during the draining. You will also torque everything to spec yourself and know the job is done right.
I also keep all of my receipts and keep a log as to work done, just in case.

Good luck.

First off, never trust the warning lights on a vehicle. Especially an oil light, they are usually too little too late. However, at this point i wouldnt be too concerned. Let them see what caused the issue and then they should check how the engine runs. If the engine didnt seize then you may have some internal damage or you may not. No way to really tell without pulling the engine and breaking it open. I would however raise hell with the dealer and push them to extend the warranty on the engine at minimum.

is this the first time taking it to this dealer? what province are you from?

Should be fine, but hold out for the million mile extended warranty and learn how to do oil changes yourself. They throw the least qualified of their lackeys at oil changes.

Had something similar happen to me. Pretty sure they drained my Diff and forgot to fill it. Have done all my maintenance up until a Trans fluid change. Bottom line is unless you know some solid trusted Toyota Techs take it to dealer otherwise do it yourself. Hacks are numerous out there these days.





Help Noise after Dealer Transmission Fluid exchange

It's coming from one of two places. Climb underneath and see if it's coming from the drain plug or the filter housing and you'll know which one they didn't tighten correctly.

Unfortunately as the others have said, it's usually the dingleberries they put on oil changes. Amazing how often they can't get it right.

So they sent two techs to my house to address the issue cause i refused to turn the engine on. From the 6.2 L about 2 L remained... the O ring on the filter was broken because of the little guide. It caught it...
they poured new oil and replaced the filter only. Reused the original plastic filter holder.

The engine runs smooth... but i still dont trust it.
I dont want them to break down my engine and examine it, if they cant even do a simple oil change....

Actually no this was the better of the 3 dealers... i trusted these guys more
Am in Ontario

I agree, they should double check the work, the o-ring was broken they showed me, when they came over tl fix it...but the kid that is changing the oil doesnt realize we put our hard earned money into a $60k truck... and it's not acceptable.
