GM asks judge to throw out ignition switch case over 'fabricated' key

According to a GM court filing, plaintiffs Zachary Stevens and his parents and their lawyers showed jurors in Harris County court a key attached to a chain containing several other items, claiming it was the one used to drive the 2007 Saturn Sky involved in the crash.

But GM said the key displayed in the courtroom did not in fact belong to that vehicle. The carmaker, which recalled 2.6 million vehicles in 2014 for defective ignition switches, has warned that added weight to key chains can cause the switches to slip out of position.

Stevens said ignition-switch rotation caused him to lose control of the Sky, hitting another vehicle and killing that driver. His 2015 lawsuit is the first to go to trial among roughly 20 pending in Texas state court.

In its filing Monday, GM said Stevens initially said he was driving with just a few items attached to his key. But the key chain shown to jurors comprised three rings holding additional items like a souvenir Eiffel Tower and gym membership card, according to the motion.

GM said plaintiffs “fabricated ‘evidence’” to support their theory that key rotation, not Stevens’ driving, caused the crash. A manslaughter charge initially brought against Stevens was dropped following GM's recall announcement.

The company asked the judge to either dismiss the case altogether, or to inform jurors about the allegedly false statements with instructions to disregard them.

The alleged misstatements "have hamstrung the search for the truth," GM wrote.

Lawyers for Stevens were not immediately available for comment Monday. GM declined to comment.

Earlier this year, a judge overseeing federal switch litigation dismissed the first of those cases to go to trial. The only switch case to reach a jury resulted in a verdict absolving GM of liability for a 2014 crash in New Orleans.

GM has paid roughly $2 billion in criminal and civil penalties and settlements in connection with the switch.
