I was wondering if anyone has had an issue with the rivnuts(nutserts) that are used to secure the the bellypans. I had to have 7 of them drilled out and replaced due to them spinning and not allowing the bolt to be removed. To me this seems to be a workmanship issue in the maufacture process but apparently Lotus sees this as a maintainace issue and did not cover it under warranty.
Has anyone else had similar problems with their cars?

Sounds like a service tech with uncontrolled use of torque. Never had any issues but that is exactly how it happens. Defintely a warranty issue or up to dealer to cover. This is NOT a routine maintenance issue!!!

If a shop is doing the work, then they might be tightening them too much. It could be a corrosion issue. Or it could be a problem with the design, panels too thin, materials too soft, wrong rivnut used for the above...

It's pretty easy for it to be #1. And they should replace them unless they can show it was corrosion.

If you are doing the work, try using a pry bar or screw driver to pry up under the head of the bolt or to separate the panels, sometimes that is enough to keep the rivnut from spinning.

I had a issue with one of mine and it was eating time with no hope of getting it out. Someone posted a thread where they drew in the tooth edge of a power saw blade until the resistance was so much that it allowed it come come free.

It worked like a charm. I even was able to get it out with not so much effort.

Had the same problem with my Elise, luckily it happened when it was being serviced. Ther fix was to put a couple of welds either side of the nut. Don't forget to protect the electrics if you decide to use a welder!

Thanks for the input. I couldn't see the reasoning behind them calling it a maintenance problem especially with my rear pan that I always antiseize coat the bolts when they come out and on my front pan they were as installed by the factory. I have to guess the guy in Hethel who was working the rivnut gun on the day my car was made had a few too many pints at lunch. I'll push the issue a little more with the Lotus tech rep.
