More Trouble for GM Over Faulty Ignition Switch – Can a Settled Case Be Relitigated?

One of the causes of action a plaintiff can bring in a product’s liability lawsuit is a defective design claim. General Motors is facing multiple lawsuits over faulty ignition switches installed in the following vehicles: Chevy Cobalt (2005-2010) and HHR (2006-2011); Pontiac G5 (2007-2010) and Solstice (2006-2010); Saturn Ion (2003-2007) and Sky (2007-2010). More than 2.6 million have been recalled.

A Georgia couple who settled a lawsuit with GM for their daughter’s death is suing again on the grounds that GM’s lead design engineer lied when he testified he had no knowledge of any design “changes” to the switches. Their daughter was killed when her 2005 Cobalt slipped into accessory mode, cutting off the engine and causing her to collide with another vehicle. Her family settled based on this information.

But in recent disclosures to the National Highway Traffic Safety Administration and Congress that testimony appears to be false. The company apparently knew about the problem for years. Now, the family has filed another lawsuit claiming they would not have settled if they had known that evidence was concealed. GM denies the accusation.Settlements are contractual, and therefore, considered final once the parties agree to the terms.  Like all contracts, there are certain situations where a settlement agreement would be deemed void.  In this case, plaintiffs would have to convince a judge that they were somehow misled or defrauded by what GM did or said in order for the settlement to be void and the case to proceed.
