Last week Tesla Motors filed suit against Hoerbiger Automotive Comfort Systems, and their inability to produce a workable “falcon wing” model in a timely fashion.

Some Of The Frequent Model X Delays Coming To Market Were Likely Caused By Falcon Wing Door Operation

Tesla reported delays on the falcon wing door mechanism by Hoerbiger forced the company to  source an alternate supplier in May of 2015, just months before the Model X was ultimately launched (in somewhat limited fashion) in September.

Hoerbiger was first put under contract with Tesla in February of 2014.  Tesla's recent lawsuit, if successful, would prevent the parts maker from making any further demand claims for services rendered.

Now, Hoerbiger has refuted Tesla's position, saying they were in fact, ready to go.  In a statement (via WSJ), the parts supplier said:

"Tesla Motors, Inc. repudiated its agreements with Hoerbiger in May 2015. By this point in time, Hoerbiger Automotive Comfort Systems was already fully prepared to begin high-volume production according to Tesla’s most current schedule... Hoerbiger was in compliance with the specifications stipulated by Tesla."

Tesla had earlier put the failures on the hydraulic design by Hoerbiger saying it leaked oil, became overheated and eventually ceased working.  Tesla later went with a electromechanical design.

The parts maker also retorted to this assertion, stating that its work on the actuator was not the root cause of the problems cited by the automaker, and that its system functioned to all of Tesla's stipulated requirements.

Who is ultimately telling the truth in this "he said, she said" legal battle?  We will let a judge decide.
