    Amazing. The reason is that the venting opening for gas (literally) emerging the tank is placed at the rear, left side, near the exhaust. Thus, if the exhaust emittes flames (as it sometimes happens, in particular when reving at stand) these flames ignit the explosive gases being emitted at the same time from the close-by tank vent outlet.

    Simple to avoid this: relocation of the tank vent opening to a better place.

    Here is a video explainiing all this and showing a proper modification. Unfortunately in German, but explaining the above. As one example for these cars catching fire at the left rear end, also a case discussed here (burning car in an Arab country) is presented.

    Quite amazing how that has been "engineered". Even more amazing that Lamborghini apparently did not feel it necessary to call back the cars for a (very simple) modification like explained in the video. Customers of modern Lamborghinis are not of the same kind as those, who know every screw in their classic one by name and of course have modified stupid designs since long by themselves ... :D.

    Cheers, Bernhard

    Funny, Lamborghini seems to argue that the part in dispute is not a venting opening for gases to emerge from the tank, but a venting opening for air to enter into the tank. Thus, the explanations provided for the fire ignitions are foolish and due to lack of engineering knowledge.

    *loooooooooooooooooooooooooooooooooooooooool*

    Or to say, this is a hose connected to the gas room of the tank at one end and open to the atmosphere at the other end. You name it what that is and in particular how either kind of gas shall know in which direction the engineer allows it to flow (atmospheric (??) check valves? why, if so, not name it?) ......... :D :D :D Funny that quite a number of cars have started to burn at exactly the same place of the rear end, and exactly at this location the venting (for whatever purpose) by strange coincidence has an opening.

    The German Federal Motor Transport Authority is investigating since short and we will see whether this technical expanation :D is convincing for them ...... :D. In case of the Gallardo hydraulic hose issue (also reason for fires), the Authority ordered them in 2012 only, to call back the 2004-2006 models ...

    I got flamed for pointing out that this is a critical design flaw. lol.

    I don't recall. It was more of a post pointing at all of the models. I think it was when a 6.0 went up last year.

    The statement I made was to the effect of "I am surprised someone has not gone after Lamborghini about this as every single one of their cars has had this issue"... then I was labeled as sue happy or something..

    My point was just that its a common problem and at this stage in the game they should have it sorted. It wasn't long after this statement that we started seeing Aventadors going up. lol.

    That's quite funny, haha. I'll let my local Lambo dealer know, if he doesn't. :)

    That's some serious backward thinking on Lamborghini's part. Which Lamborghini's affected this? Aventador, 6.0 I'm reading, Murcielago too? It's an easy enough fix, and something I'd definitely do when I'll have my own...

    Side note: Why does that man tuck his ears into his hat?

    I own an 2013 Aventador that I bought new. It has been perfect so far. This is my 3rd Lamborghini and they were all good. My 458 has been good also but I did have a oil hose come off when I was driving scared the hell out o me. My 360 and 430 Ferrari's were good also.

    I will say my friend destroyed his clutch in 200 miles on his 12 cylinder Lamborghini. This was the earlier model .I suppose if you want to beat a car buy a Corvette. You cannot kil them and they are very good drivers cars.

    The only cars I avoid now are made in England. My Meclaren died the third week of ownership. They are great cars to drive, maybe it is not a problem for most.

    My car was 12C. It was a very good drivers car that you can set to your desire that day.


    The cars fluid goes through the front bumper for cooling I believe. This is for the clutch.

    The car was very new and I was out driving with a friend. The cooling fluid started leaking unknown to me. The car stopped moving so we were stranded. The dealer fixed it under warranty. The problem is at the time there were only three dealers in the USA. The closest to me is 4-6 hours away. I traded in the car for the Adventador I own today.

    My three previous English cars, two of them had stranded me. My Lotus Evora turbo S would not start the third week of ownership. This was a brand new car. To make things worse The dealer was no longer honoring warranties. I keep all of my cars in a storage area. so all of my cars wee blocked.

    The dealer no only did not help he was aggressive towards me. This plus all of my friends, four owners were having galling problems on their Lotus cam shafts. I took the cover off the cam and the lubrication holes that were drilled was done incorrectly and restricted oil flow.

    So although I love the look an drive Of British cars I now avoid them, they are just not worth the aggravation.

    On the positive side I love my Italian, Germain and American cars. They are great drivers cars and have been reliable. The big surprise at least to me is the C7 Corvette. It is just wonderful to drive and own. I think it is as good as Europe's best. The only car in my collection that is at least as good is the Audi R8 V10.

    Best

    I think the fire problem needs one more factor.

    When I watched the video of that Adventador burn in Dubai something caught my eye

    Look at the video at 24 to 34 seconds , I think that little white puff of smoke is raw fuel

    https://www.youtube.com/watch?v=2fW6QX_RNLQ

    It looked like he hit the rev limiter and lots of unburnt fuel was sprayed on the back bumper, the next flash of flame the car started burning which then probably finds that fuel vent mentioned above.

    Lamborghini Lambrusco Engineering at it's finest. Lambrusco Engineering is when the factory staff go on a 4 hour Lambrusco fueled lunch and come back to the factory and try and do 4 hours of work in an hour to catch up on their long lunch. Obviously the tradition continues on the Adventador.

    When we restored Taffy's LM002 we found all sorts of hidden shortcuts and dumb design that the LM owner would never see or think about.

    Putting the engine ECUs under the drivers seat in an off road vehicle was one example. These were submerged in water from a windscreen leak when Taffy got the LM but having done a lot of off road this area will regularly see water if any creek crossings are attempted and this is supposed to be an off road vehicle.

    The beautiful leather covered instrument panel looks like it used raw wood from an old olive oil bottle packing case.

    The exhaust manifold heat shields were patched together from mamma's old cooking pots. Seriously ? You should see these things !

    ANSA headers left , stock 'mamma's cooking pot' exhaust on the right

    The worst one for me was a brazed copper fuel line divider right next to the header. Copper brazing melts at around 450 to 500 deg C and those temps are possible near the header. We replaced this cobbled together copper divider with a proper aftermarket fuel divider.

    Actually, talked to my local Lambo dealer, he was like "very not funny" about the vent. He said that often the problem is more related to catalyst temp probe. Something like the probes themselves overheat too much and can cause fire or meltdown. It's kinda secret, but you know.

    BTW, "mamma's cooking pots" do help power, emissions and heat under the hood. They help rust too, you know!
    High-temp headers (wrapped, "cooking pots") have higher exhaust temps inside which changes the wave length and power of the waves inside the exhaust. If you want more on wierd exhaust stuff, here is something to read:

    These issues you raise are not unique to Lamborghini. You can find similar examples from some of the other marques from that region. Emissions control in particular was something they took a very long time to get right. Lot's of opportunity for fires with that alone.

    I haven't been back to the factory in over 20 years but my impression is that they aren't have construction problems like this any more but design flaws can occur in even the most modern and highly regarded cars.

    Of course, Audi is the absolute king of design flaws. People tend to think the Audi's flaws are cleverly pre-engineered.

    Yeah funny how Audi rarely gets bashed over things like this, but of course if not for their quality Lamborghini would be dead.
