Official Lotus Response to footwell corrosion
Discussion
Hi guys,
Ive just had this from Lotus as a response to the footwell corrosion issue. It has taken some time to bring to resolution, however they finally have an answer and fix that seems reasonable.
I will be happy to supply the contact email details / numbers etc if anyone wants to query this, however didnt think that posting someone's direct line number on the web was appropriate.
Elise Footwell Floor Corrosion - February 2004
Lotus is aware that a small number of Elise models factory fitted with
synthetic mats in the footwells, have experienced some cosmetic corrosion of
the top surface of the aluminium footwell floor panels.
Lotus has concluded its investigations and would like to thank its customers
for their patience over the last few months, which has enabled us to fully
research the issue and validate the solution. These extensive
investigations involved both Lotus and independent testing laboratories
undertaking tests in an attempt to replicate the corrosion under laboratory
controlled conditions. Given the extremely unusual and unpredicted nature
of the problem it took several months to recreate the corrosion in the
laboratory using both automotive and aerospace accelerated testing methods.
Only when Lotus was satisfied that it had scientific and proven evidence as
to the cause was it able to proceed to develop and test an effective remedy.
The cause of the corrosion was established as being a complex chemical
reaction within the moisture and salts which tend to become trapped between
the floor surface and PVC matting.
Lotus fully understands that this cosmetic corrosion has caused concern to
some of the affected customers. It would like to reassure all of its
customers that the footwell floors are not part of the primary load bearing
structure of the car and that this corrosion does not compromise the
integrity of the chassis.
All PVC based matting was deleted from production specifications of the
Elise several months ago. Owners of Elise models factory fitted with
either the black synthetic (rubber like) or grey synthetic chequer plate
patterned footwell mats, are offered the opportunity to upgrade from these
mats to new breathable black carpets. These breathable carpets will provide
suitable ventilation of the footwell floor surfaces.
Lotus authorised dealers will be pleased to assess the footwell floor
condition of your vehicle and then arrange a convenient time to carry out
the appropriate improvements. Where little or no corrosion is evident to
the footwell floors, a colourless anti-corrosion fluid will be applied to
the footwell surface. In other cases, where more corrosion is evident, the
original floor will be treated and a secondary floor panel will be bonded
and sealed on top of each of the existing footwell floors. In all cases new
breathable black footwell carpets will be fitted
Whilst the footwell condition of the majority of vehicles will not amount to
a failure under the terms of the 8 year chassis anti-corrosion warranty
provided with the vehicle, in order to maintain customers confidence, Lotus
will, as a goodwill gesture, undertake the above treatment and improvements
free of charge to any Elise within its 8 year chassis anti-corrosion
warranty which was factory fitted with the PVC based floor mats (standard
warranty terms and conditions will apply).
Lotus has released this statement at this time to reassure any concerned
customer, and is in the process of obtaining stocks of materials and
arranging appropriate dealer training. Any concerned customer should
contact their authorised Lotus dealer from the end of March onwards to
discuss appropriate arrangements. Customers may prefer to have this work
carried out in conjunction with a maintenance service or other repair work
and should therefore discuss this with their authorised dealer.
The U.K. Vehicle Inspectorate has confirmed to Lotus that as the footwell
floors are not part of the primary load bearing structure and any corrosion
of these panels does not compromise the integrity of the chassis, a corroded
or perforated floor panel is not in itself grounds for a U.K. MOT failure.
Any queries related to MOTs should be directed to the Vehicle Inspectorate
Enquiry Unit on telephone number 0845 6005977, quoting vehicle test station
number and the date of test.
Lotus recommends that routine car cleaning and maintenance by Elise owners
should include lifting the footwell carpets and cleaning and, if necessary,
drying the floors.
If customers have any queries in connection with this issue they should
contact their authorised Lotus dealer who will be happy to assist. Once
again thank you for your patience.

As my car is a 1999 model, it is well within the 8 year period, however i dont think i have the warranty (on paper). Will i qualify? 
At least they have pulled their finger out and done something.
Atleast i can do and drool over the T350s at CN!
The manufacturers warranty carries over to second owners etc, however there are a rare few cases where the warranty might be withheld.
If in doubt, drop Lotus customer service a call, they should be able to confirm what the score is.
