This is becoming more common, it's not actually the struts that are leaking, but rather the lift system. Don't leave your car in lifted mode after you pull it into your garage, let it sit lowered. You can top off the power steering fluid (CHF-202 or CHF-11S) if it's starting to get low. It's not a safety issue because it only affects the lift system, the less time you spend lifted the less it will weep. Just make sure your power steering fluid is topped off and you'll be fine until the part comes in as long as the puddling stops when you keep it lowered.

Sounds like the part may be an electrical component. What exactly is the part? Without knowing that, who knows... Surely a mechanical component could even be found on a salvage or something.

I'd ask specifically what they need and see if you can just source it yourself and get McLaren to reimburse (although I doubt they'd warranty that repair and you'd be on your own if it fails again.)
They will never put a part that isn't brand new on the car, especially a warranty claim.
thats a bold statement lol
It's not a wrong one.
Well, by unanimous vote....

It's a front strut. Is leaking oil (or whatever fluid is inside - so something is broken/compromised). Apparently McLaren cannot source struts. Hence my frustration.
If you can get a part number, we may be able to source one. True story, while I was looking for a 675LT DLD I was told 3 dealers had them on order and had no ETA and couldn't find one. We found one, at another dealer. When they "can't find one" it's because the parts distribution doesn't have any in the warehouse, they don't know the tricks to locate them.

If you top off the fluid, make sure you do it with the lift down. Doing it with the lift up will make it overflow when you put it down.

Car is not left lifted ever.

fluid was brown best I could tell. Didn’t take picture of it on the floor but for some reason did take a picture of it dripping down the suspension and brake cooling duct. Make of it what you will.

not sure what path forward is. Going to call dealer on Monday about using the salvage part until they can source new.

I think I’m having the lift problem. The other day after I pulled my 720 out of the garage I found a pool of green fluid where the right front wheel would have been. I sometimes forget to lower the car. I’ll leave the car up for a while and see what happens.

I would be careful saying its not a wrong one.

Just observing this picture (Pictures can speak "a thousand words"... and sometimes they are just pictures :cool: )

I noticed some things that MIGHT give some clues as to why you are leaking so profusely? Of course having access to the car in person might give me a different perspective.


It seems this corner of the suspension has previously had trauma or at least major servicing?

- Notice the Tie Rod End... It seems to have been replaced (or adjusted) because the OEM original paint markers that are applied after a part has been 'torqued to specification' when the car was built no longer line up.
  • (blue & green dashes indicate where the paint marker are missing in the original picture)
  • (the green arrow is example of a different bolt that still has the OEM paint marker applied and undisturbed as a comparison)

- Also the Ball Joint Nut... Seems to have a shinny spot on the corner of the nut. This would indicate the wheel hub has been disassembled or removed at some time.

@tozzy234 may be right! Never say "Never"

Third party warranty companies may authorize the usage of used parts in some situations. Especially when it saves them money!
This does not mean it will be the best option for the vehicle owner in the long term, as a used part always comes with some of its effective lifespan already shortened as part of the compromise.

Having said that, Most dealerships I've encountered (all automotive brands, not just McLaren), will give you push back or just plain refuse to install parts supplied outside of their distribution system. Because they lose the profit potential for selling you the parts.
At the end of the day... It's all about making money? right?

Disclaimer! (or Public Service Announcement?) --- Every single person in existence needs to make money, I'm not criticizing that!!! (or at least have access to money that someone else earned - for all you trust fund babies out there :cool:) - So we are NOT debating the fundamentals of capitalism's here! LOL

Is this oily feeling? I had a cracked windshield washer fluid tank that dumped greenish/bluish fluid

The fluid is Green I am guessing? Most assisted shocks fail, ask a range rover owner/R8 magride.

It is not all that common on mclarens but it does happen, and the vast majority do weep from time to time especially when they have been left sitting. Normally a suspension work out changing the settings can help to get things sealing up again. I worked on a car that had a weep, cleaned it up and it didnt return

How much liquid was the pool would you say in millilitres?
Not meaning to derail the thread , but regarding weeping oil how about 570 driveshaft seals? .
after the 3rd warranty visit mine is still the same , leaks a consistent tiny ammount (takes approx 400 miles with new seal) from the offside .Their mechanics (fitters) replaced the seal (twice supposedly) and cleaned the shaft .(not damaged they said) but still there . What do you think ?diff housing plate,diff bearing maybe ,or could it be the monkey missed something on the shaft .They obviously don't want to change the box
I am at a loss and reluctant to send back as it seems to incur some sort of damage every time it goes in.
any suggestions appreciated (bail ,and buy a red pony is included )
