Spoiler lift spring brackets on both sides are broken allowing the springs to get in the way of the normal performance of the spoiler. This could impede the deployment of the spoiler or the successful retraction of the spoiler, creating a reduction in downforce (grip) or creating a safety hazard of a non-fully retracted spoiler. This was identified by a third-party repair shop during maintenance work. In doing further research online I have determined that this is an extremely common issue on this model generation (991. 1) that Porsche will not address.
