Well said. Same experience with us. My husband definitely does the mpg thing better than I do but I figure it is better than the non-hybrid version. We believe in supporting the technology, as we have both the hybrid Highlander and a Honda Civic hybrid.
 
Also no problem leaving the Highlander battery (or the Honda for that matter) for ten days while in Ireland.
We love both our hybrids and they work for us as a family of five.
 
Hope to never have the blown engine problem and I have never heard of that on here before, and while I feel sorry for the owners but suspect that it is an isolated incident. I think it would be worth writing to Toyota and the dealership outlining the scenario- there is nothing else to lose.

ahem...there is no 'hybrid engine' per se.
 
You have a 60,000 mi warranty on the gas engine and transaxel. Unless there are other issues with how the vehicle was being used ( towing a 12000# trailer? ) how is it that you don't have a valid warranty claim?
 
There's too much missing here to reach a conclusion. I certainly wouldn't give up on this.

My understanding..
 
Apparently mice got into the engine compartment, chewed through the wire insulation on low side of the injector circuit, the bare wire shorted, dumping massive amounts of fuel into the cylinder resulting in hydro-lock....
 
Piston rod ejected through the engine block.

Very good, that is apparently the final analysis.

I do not have issue with the finding.
 
Mine is with the cause of subsequent damage.
 
If I did this on a lonely stretch of road they would hold me responsible for operating this expensive state of the art machine after violent shaking begins.
 
Why am I responsible when the dealership causes the subsequent damage???

I have contacted several experts on this matter.
 
1) Bad gas should be easy to rectify and eliminate.
          a) purge all fuel possible from system.
          b) change filters
          c) add known good fuel
          d) idle car till fuel behind injectors is replaced with know good fuel from tank (approximate idle time up to 5 minutes). (I see this step being a challenge for a toyota hybrid idle is to charge hybrid battery)
          e) scratch head and look for something else causing violent shaking of engine.
 
2). This whole scenario has a problem to it. The engine was shaking violently. Why run it at all. I chose not to. These guys are the pros. Get tech in from out of Town to figure it out or admit not qualified and recommend qualified facility. I do it every day in my work.

I would assume that what happened is that someone left the ignition on for a period of time without immediately starting the engine. Then when a start was attempted the cylinder was already filled with gasoline, or at least enough to bend or break the piston connecting rod.
 
Hard, for me, to find fault with anyone but the mouse.

Thanks,
 
That could be I appreciate your input on the matter.
 
I recall the tech. calling me and telling me that it was sitting their idling and smoked. In fact the salesman of my second car from this dealership said he was watching it when it blew.

Don't know if I mentioned it.
 
Before they were able to figure out the violent shaking (bad gas, chewed wire or blown engine) dealer went ahead and performed 30,000 mile service and rotated tires.
 
I mention this because some have asked me if oil levels etc. were at proper levels.
