    Love my Tribeca! However, picked up my new Tribeca three days ago, drove it approximately 120 miles total. Something let loose in the engine and blew a hole in the engine block. Boy, were they surprised! The dealer is ordering a new short block and replacing the engine. Anybody heard of this happening before?

    Wow, that is just bizarre.

    All I can think of is the timing chain broke and the pistons hit the valves or something.

    That's the first time I've seen that here on Edmunds, not just for the H6 but for any Subaru engine.

    Wow, That is strange. That's first H-6 (or any sort) that I'm aware that had that happen.

    Wow ! I would demand a new vehicle, actually start out with a nice reasonable request and then go to SOA if necessary ... :lemon: ?

    Ditto... I would definitely want a new vehicle. sorry to hear about your problem

    Ditto on the replacement vehicle. I would go to the top if necessary to get a new vehicle. I am not even happy about having my car ripped into to replace the airbag module - wherever it is located. I just don't trust the work of local mechanics - not most of them anyway.
  • Update on the Tribeca engine that blew at 120 miles.... The bolts that hold the flex plate and torque converter between the transmission and engine block weren't properly installed or "torqued down". As the car was driven, these bolts backed out and the blow out was when one of the bolts came all the way out and blew a hole in the coolant jacket. This also made some kind of crack in the transmission too. Subaru is now replacing the engine and the transmission. As I am not a mechanic and don't understand mechanical language, I hope this makes sense. Thank you for your thoughts on this matter. (I can't wait to get my Tribeca back.)

    Keep all the documentation once it's fixed up. The good news is that if you have any more problems down the road, I bet SoA will be more likely to help given what you had to put up with early on.

  • WOW. I will ask for a new car. It will take awhile just to get the engine and tranmission, never mind the re-install. I think someone posted that it took weeks to get a airbag module, I just can't imagine how long the wait would be. Dealer's mechanic will likely to screw something up too. Check your state's new car lemon law. In NJ, where I live, you are entitle for a new car or refund if you 'new' car is out of service for more than 20 days in the first 2 years.
  • Update on the Tribeca with the blown up engine due to the bolts between the transmission and engine block being improperly torqued...

    I now have my Tribeca back after 23 days in the shop. The biggest problem was SoA had a difficult time properly packaging and shipping the transmission. One ended up sitting in Arizona in a leaking package before SoA "overnight" air-expressed another one. My car is back together again and seems to be running great.
  • Ouch... I feel your pain. I wonder how much overnite cost...... :) I think they lost money on your car...

    Thanks for the update.

    It was probably the first time they had to ship a new tranny, so I guess the learning curve applied.

    How many miles did you put on the loaner? :D

    Good luck in the future, hopefully you'll have a perfect one from here on out.

  • I took my Tribeca to my local dealer because some of the fluids were low. ( It was prepared correctly at a different dealer). So the next morning, 75 plus degrees, when I start the car, it went up to 2100 rpm and stays there. After driving for a few minutes it went back down to normal rpm. Every day since then when I start the car it goes up to the same 2100rpm regardless of the ambient temperature. ( As an aside, I also had to re program my memory seats after I left the same dealer). Any ideas why this is happening and is it hard to correct?
  • ateixeiraateixeira Posts: 72,587
    That seems a bit high, but rpms should be elevated until the engine is fully warmed up. Do other owners observe the same thing?

  • The thing is it started correctly until I took it in for the service. ( i.e. it cranked maybe once & then turned on. And the engine did not race at all). Now when I put it into drive, it sort of "bangs" into gear b'cse the engine is going too fast. Is there a any manual adjustment for the idle or is all computer controlled?
  • aka1aka1 Posts: 110
    Nothing to worry about- the dealer may have disconnected the battery (hence having to reporgram your seats) and the engine computer is still learning. It should usually correct it self within 4- 5 starts- however you are now consciously looking for any extra perceived RPM's at start up. Now that its cold, my B9 hits 2K rpm then settles back down...
  • Has anyone else noticed an annoying jerking sensation when you are just cruising along at non-highway speeds? This usually occurs when the engine has to pull a little harder prior to the transmission deciding to downshift.
  • I'm new to any subaru and I definitely do not like that my new B9 hits 2k right from the start and settles back down. None of my other cars would do that. I understand it's below 30 now outside, but its noise at 2k from the start is just quite a bit too loud to me. This is supposed to be the top of the entire Subaru line.
  • ateixeiraateixeira Posts: 72,587
    Subies are designed for ultra-cold climates, so elevated RPMs are probably there to provide a quicker warm-up and more importantly heat to those that are freezing cold.

    I say crank the tunes and enjoy the heated seats! :shades:

    If you thought you were getting a luxury car, Subaru isn't it. Look at Audi, Lexus, MB, BMW if you are looking for that....
