The Aventador is so unreliable

It,s possible for your stalling issue it could be your carbon canister is full and needs replacing,if you take it to the dealer ,have them carry out recall campaign L73X-R-0117.Your car being a MY12 under this recall campaign would be upgraded with the following:

 

EVAP system(Robustness pack)

Purge valves

Fuel cap

 

After which your Engine ,Gearbox & Instrument software will be upgraded to work together with these new hardware.

This should solve your engine stalling issue when driving in traffic jam in hot weather.

Another possibility for your engine to cut out could be an issue with your complete engine wiring harness,this issue with wiring harnesses mainly is an issue in hot climate countries such as Bangkok.The problem with wiring harnesses is the connection issue with the main plug of the harness going to your engine ecu located in the RH rear wheel arch area.This wiring harness issue is very common in hot climate countries.

 

I think you may also have an issue with battery current drain on your car.

 

As for your temperature u need to check with your engine running if both LH & RH radiator fans are running,possibility with Aventadors sometimes a small pebble or stone is stuck in between the fan & the fan shroud,you should also get the dealer to carry out service campaign

L83X-A-0714 Coolers and air ducts replacement ,this replaces both radiators and new versions of air shrouds.

 

Most of the other fault codes which appear when you are just starting up your car is most probably mainly caused by low battery voltage during the cranking phase ,once your battery/current drain issue is fixed this should not appear while initial starting provide those systems are trouble free.

 

Best of luck with your car,let me know if you need any more info.BR.

 

Very good info - once the car comes back from the shop tomorrow, I'll have a run. If there is still an issue, I'll print your post and take it to the service center, which should re-open by next Monday.

The shop is now doing a test drive. They informed me that they changed the power supply and there was also a problem with the signal getting to the fans, which was also fixed. I'll get the car tomorrow. I think it makes sense.

hello, sorry to hear about the issues you are experiencing. my Malaysia aventador is a MY13 and though it never had any electrical issues so far (fingers crossed) (i do hook it up to the battery charger whenever not driven and recently had a battery replacement as precaution after 4 years with the car), i have had start up problems. it would happen in high temperature stop and go traffic. i did some campaign at the dealer which included changing many parts and even the fan, and no problem for years until last year i couldn't start after stopping for gas, and as it turns out it was something about the starter. this was subsequently replaced as well. no problems since. total 3000 miles on the car so save for these incidents the car has been very reliable.

 

i think if you can get your car to an authorised dealer with a competent mechanic as well as all software and parts campaign, you should be able to fix this. both my '11 gallardo and '13 aventador have been very reliable supercars (so are my F cars). hot and humid climate not friendly to these machines but there are fixes.

I have almost 30 000km on my '14 Roadster and had to send the car to the workshop 3 times (twice for the catalyst overheat issue) but other than this the car is reliable and I have more glitches on Ferraris that I drive much less. However I will sell it before the warranty ends in 2019 as I expect a car like this to behave irrationally...

Back with some updates, the car got out of the shop last Saturday. They say they fixed the fans that were causing an overheat, and changed the "power supply".

 

On Sunday, I test drove to the mall in heavy traffic for around 45 mins, no issue at all.

Two hours ago (it's evening here), I went to buy some stuff at 7-eleven, not even 2km from my place, and on my way back, the car stopped right in the middle of the road with "low voltage, check power supply" message. Took around 5 mins before I could start it again, drove to home, and when parking the car, the engine stopped a second time and flat out refused to start again, so we pushed the car.

 

The towing is coming to pick the car tomorrow for the 7th time. Fortunately, the official service center re-opened last week so I'll be able to get a certified mechanic to look at it.

 

I know that "this is not a Toyota" and that exotics are prone to have some issues when we drive them like a jackass, but I don't think it's normal for a car of this price to randomly stop in the middle of traffic and refuse to move.

Very sorry to read of your continued troubles with the car.

 

Do you have a lemon law where you live?

 

Sounds like a great candidate for a buy back....

I am suspecting that the alternator might have something to do with it. What do you guys think?

 

Like many have mentioned, low voltage kills newer cars. Bad grounds are worse. I would bet the previous owner had the same problems thus

letting it go. 2012 cars had many problems. They are the cheapest but once again, there is a reason why. I can't believe it cost 900k there to

own one. I wish you the best but the dealership certainly is your best shot. I know you are limited.

The car is at the dealership now. I took videos of the car acting weird and showed them to the tech guys there, and they are pointing out 3 possibilities:

 

1) A bad ground. They will check all the ground points near the wheels.

 

2) A bad relay. As a precaution, they'll change all the relays in the relay box.

 

3) Dirty air entries. They will clean them all and ensure proper airflow.

 

I am leaning more towards option 1. I'll know tomorrow.

SiamBeast, sorry to hear about your car.

 

Normally when exotics get driven a lot they perform better than those that are driven sparingly (like most of them).

 

Very atypical and I suspect you've had an unfortunate example.

 

Best of luck to you.

Hi Siambeast,

 

Yes maybe your car has a defective alternator or a loose ground,best when in dealership they use diagnosis tool to first clear all the fault codes from all systems as a low voltage stalling will generate a lot of faults in the system which are false ,after which they can restart your car with diagnostic tester plug in and look at the measured values through the tester with engine running,that can tell the actual voltage generated by the alternator,if the alternator is giving out low voltage a warning should also appear on your instrument cluster.

Another possibility in regards to the alternator could be its supplying enough voltage but the diodes inside the alternator are faulty leading to a voltage reversal inside the alternator,this is not a common issue but possible.

Another thing to check is the whether the main voltage wire going to the jump start point in your engine bay is tighten properly,this cable is the thick one that goes into the small black box on the RH side of the engine bay closest to the RH rear bonnet linkage ,also get them to check whether there is a lot of moisture in your engine bay fuse box located just behind RH airfilter housing.

Although not common but possible is whether there are rat bites in your engine bay wiring harness .

 

The main voltage cable from alternator is also linked to the starter so best check that also for proper tightening .

 

Best Regards.

Just sent that to the mechanic, thanks. They're still working on the car as I write this.

Report from the mechanics today:

 

- Ground point check and clean

- Throttle body clean and adaption

- Air filter replaced

- Main relay replace x2

- Charging system inspect and check

 

Need to road test tomorrow to complete the throttle body learn procedure, and send results to Lamborghini.

 

Makes sense?

They should read the diagnostics if they already did not.

 

I am very sceptic that air cleaners have anything to do with electric gremlins.

The mechanic called me today. He did what I described above, test drove the car during 2 hours, no issues at all. When bringing the car back to the garage, it stalled in the workshop right before he was about to send the car back to me. He opened the front bonnet and found out that the positive pole INSIDE the battery was loose - indicating a faulty battery. We're waiting for a battery replacement.

 

IMO it makes sense since the car was only stalling when I was stopped, or when I was stopping and just about to reach 0 km/h.

 

Your thoughts?

So I bought this 2012 Aventador 5 months ago, only 4,900 km on the counter. So far:

 

Month 1: After 3 days idle, car refuses to start - battery problem. We get a brand new battery in place, it now works. Took a week.

 

Month 2: I try to start the car after a night out... hear the initial sound, then the "vroom" sound, then the RPM goes back to 0 and the check engine light appears. The car starts after the 3rd time.

 

Month 3: Same problem, but this time, the engine stopped when I was backing into a parking space. I got the car towed by security measure, paid $2,000 in repairs, and they guaranteed the problem would go away.

 

Month 3: A week later, I'm driving forward into a parking space. As I slowly move forward following the security guard's motions, the engine stops again. It stopped when I was completely in the parking so I didn't have to start it again, but still, it shouldn't be doing that.

 

Month 4: I take the car to a nice bar downtown. At the end of the evening, the car, parked right in front of the terrace with everyone looking, just plain refuses to start. One time I just hear the initial sound with no "vroom", second time I get the Vroom but RPM goes to 0. Third time, engine starts, but as soon as I put it in gear, it stops. The next 40 tries were a combination of the above. I left the bar with the car on a towing, under the laughs of everyone at the place.

 

Month 4: Two weeks later, I stop the car at a police checkpoint, shut off the engine, and blow in the breathalyzer. I am under the limit, so I start the engine again, this time it starts on the first try but I get a "rear wing defective" message on the dash.

 

Yesterday: I was driving in Bangkok traffic, and I was stopped around 15 minutes at a red light, with the car on Neutral, on Strada mode. The engine just decided to shut down by itself, with "Low Voltage, Check Power Supply" message. I try to start the engine again, I just hear the initial sound, no vroom. The traffic starts moving and I have to put my emergency lights on. I start a second time, I hear the "vroom" but the RPM goes back to 0. Third time, it starts. I put it in gear, drive around 10 metres, and it shuts down again. I manage to start the engine and pull in a parking where I called the towing, who towed the car to the garage for free out of sympathy.

 

Now I'm still waiting on the mechanics to find the problem. So far, they're saying that it's because the car didn't have enough gas, but I was on the line where the red part starts - shouldn't be a problem, so I cannot believe them.

 

If anyone from Lamborghini sees this, it is unacceptable for a $900,000 car to be unreliable like that, please get your shit together.

 

My wife's sister offered to trade my Lambo against her Honda Civic, which she claims starts everytime.

 

 

Sorry for all your troubles, I had issues like that with Diablo's years ago. I get it. Not fun at all.

 

Ive been to Bangkok many times and a Lambo there is a handful of car to drive around. I seen them there and thought about what it would be like driving them-lots of work.

 

best of luck, FWIW I had more problem in the heat in Vegas than I ve had in LA, not sure but the heat/humidity there could be making the situation worse. There are smarter guys here than me for good advice.

I had a 2012 Aventador with the same issues all the time... Everything stopped after i traded it for a 2014 Roadster !!! Get rid of that shit...

Unfortunately reliability and Italian cars like Lamborghini just do not go together. No excuse for that.

My experience is if you want reliability choose German cars like Porsche. If u want looks then Lamborghini but suffer unreliability :rolleyes:

Not sure why we are generalizing Aventadors as unreliable. Everyone I know with one, apart from having a few issues with 2012's, have been trouble free.

I agree . I have a 2015 with 15,000k on it and just took it on a 2500k trip and it has never skipped a beat. And I drive it like I stole it every day lol.
