Alloys Corrosion (Blisters Formed)

[adridodo]

Lads,

This is UNBELIEVABLE, my alloys started corroding (blisters formed on them) AGAIN on my Is 220D only 5 months after getting new 1s !!!

The other set was changed under warranty but now that my warranty ran out I will have to pay for them myself ...

Did anyone found a solution (getting a different type/material e.g. steel or painting them etc?)

Cheers,

Adrian

Typical Lexus alloys- nothing changes! Had the same issue with my IS200 alloys years ago.

Your best bet is to get yours alloys striped down and get them powder coated profesionally.

This winter's salt and grit has done you no favours.

Mine too.

Lexus doing things on the cheap no doubt

All manufacturers seem to be suffering from this problem. I have been reading some research that although it is something that car manufacturers and the makers of alloy wheels should maybe take into account; it is mainly a problem arising from a driving style involving regular and frequent last-minute heavy breaking from high speeds rather than planning ahead a bit. I am not suggesting that is so in your case, but if you have to replace your brake pads and tyres more often than most, it could be. Frequent very heavy braking raises the wheels to temperatures which makes the paint/lacquer on the wheels bubble, and there are no sufficiently decorative finishes at the moment that can withstand these temperatures. An anodised finish would achieve this and is very tough but just doesn't give the look most people want.

I wife owns a 9 year old IS200 with the original alloys. Whilst each one has been kerbed, there is no blistering whatsoever. So Lexus CAN make alloys that don't rot if they want to. Maybe cost has something to do with it.

I've got a Mazda 6. Whilst they haven't blistered, they do seem to get burnt by hot brake dust. (tiny black specs that are a swine to get off). I note that this problem afflicts the ISF side skirts as well. Could be that manufacturers test mechanicals and electrics to destruction and wheels and side skirts are overlooked.

I have an 08 220d. Just noticed today a number of small corrosion blisters on two of the 17' alloys. Whats the normal prognosis? Is first discovery generally followed by rapid deterioration? Car is under warranty until feb 2011 so i will need to act in the next few months.
