Car Care Nut is probably my favourite show. So relaxing to watch! Seems very “Toyota” fair

very talented



 

I just had to replace two of these in the same van, failed back to back and then the trans died. Junk car lol! No idea how one car was so cursed at only 114k miles

 

Brand? Toyota

 

2012 Senna van, cheap feeling car and massively underpowered on top of these repeated failures.








The more cars I work on the more I see unlikely stuff like this. Still, it was surprising how bad this car was. IMO not worth it at all to own

 

CCN says the engine failed because it was stressed all the time due to plowing snow. Maybe, but in the Sienna it's probably over stressed as well that thing is heavy. Load it up with junk and people and it could easily be over 5000 pounds.

 

That would fit actually, thing weighs over 4k as is! Both engines died due to chain failure though so I am not sure the weight has anything to do with it? Trans failure I can totally see the weight being the problem

 

What engine is that?

 

Looks like the old 2.7 liter (1AR-FE) that was used in the Sienna and Highlander (maybe Venza?). It was dropped from the Sienna. The last year it was offered in the Sienna was 2012.

 

Thanks. Never knew the Sienna had a 4 cylinder

 

Actual chain failure?

 

Twice. Once on the original engine and the replacement used engine had the same failure, I said enough of this and went with a JDM imported rebuild after that.

Chains have this issue sure but I wasn't expecting it from sub 150k mike engines but perhaps I should just start assuming and requiring customers to replace them. I'm now up to 11 chain failures this year alone.....sad since in theory they should be lifetime parts. I guess lifetime is long enough for warranty!

 

Always enjoy the pics and your insight.
Like watching the engine tear downs and autopsies. lol

One thing for sure, you're a hard worker and not afraid to rip the car down to the last bolt.
