( CNN ) -- Toyota has reached a settlement with two families over product liability claims following a crash that killed four family members , a spokesman for the automaker said . California Highway Patrolman Mark Saylor ; his wife , Cleofe Lastrella ; a 13-year-old daughter , Mahala ; and Saylor 's brother-in-law , Chris Lastrella , were killed when a Lexus sedan they were in accelerated uncontrollably on a freeway near San Diego last year and crashed over an embankment . Lexus is a division of Toyota . `` Toyota and the Saylor and Lastrella families reached an amicable agreement in mediation that fully resolves their product liability claims against Toyota and a Lexus dealership , '' Brian R. Lyons said . `` Through mutual respect and cooperation , we were able to resolve this matter without the need for litigation . '' Lyons said the company and two families `` wish to keep the amount of the settlement confidential . '' Saylor family attorney John Gomez told CNN affiliate KGTV in San Diego that as part of the settlement , Toyota did not admit liability . An investigation revealed the accelerator pedal in the car probably became trapped on an all-weather floor mat that had been incorrectly installed in the vehicle . Toyota issued a recall to address possible floor mat entrapment . A 911 recording obtained by KGTV reveals a desperate call from inside the car as it approached the end of the freeway . `` We 're in trouble . We ca n't ... there 's no brakes , '' Chris Lastrella said . `` End freeway half mile . '' CNN 's Greg Morrison contributed to this report .
