(CNN) Paul Walker's daughter has filed a wrongful death lawsuit against Porsche, claiming the sports car he was riding in had multiple design flaws. 
 
 The suit, filed Monday on behalf of 16-year-old Meadow Rain Walker, seeks unspecified damages for defects it alleges contributed to her father's death. 
 
 "The bottom line is that the Porsche Carrera GT is a dangerous car. It doesn't belong on the street," Walker's attorney, Jeff Milam, said in a statement. "And we shouldn't be without Paul Walker or his friend, Roger Rodas." 
 
 Calvin Kim with Porsche Cars North America said the automaker hasn't seen the lawsuit and wouldn't comment on specifics. 
 
 "As we have said before, we are saddened whenever anyone is hurt in a Porsche vehicle, but we believe the authorities' reports in this case clearly established that this tragic crash resulted from reckless driving and excessive speed," Kim said. 
 
 The actor was best known for his role as Brian O'Conner in the "Fast & Furious" franchise. His life was cut short in a car crash in Southern California on November 30, 2013, during a few days off in the filming of the seventh movie in the popular series. He was 40. 
 
 The lawsuit alleges "the vehicle lacked safety features that are found on well-designed racing cars or even Porsche's least expensive road cars -- features that could have prevented the accident or, at a minimum, allowed Paul Walker to survive the crash." 
 
 The court document contends the 2005 Carrera GT should have come with an electronic stability control system to protect against swerving. The car also lacked adequate side door reinforcement bars and had defective rubber fuel lines, according to the lawsuit. 
 
 The investigation 
 
 An investigation by the Los Angeles County Sheriff's Department said it was speed that killed the "Fast & Furious" star. 
 
 "Investigators determined the cause of the fatal solo-vehicle collision was unsafe speed for the roadway conditions," Los Angeles County Sheriff's Commander Mike Parker said in March 2014. 
 
 The high-performance 2005 Porsche Carrera GT was going "between 80 and 93 mph at the time the car impacted a power pole and several trees," the report said. The posted speed limit on the Santa Clarita, California, office park road was 45 mph. 
 
 The sheriff's conclusion was no surprise, since the coroner's report previously estimated the car was speeding at 100 mph. 
 
 A source familiar with the Walker family's lawsuit, however, say that investigators who analyzed surveillance video think the car was actually going slower. The suit, in fact, claims the vehicle was traveling "at approximately 63 to 71 mph when it suddenly went out of control." 
 
 The family's investigators think the car was going between 40 and 60 mph at the point of impact, according to the source. 
 
 Possibly to explain the damage to the car in a lower-speed accident, the suit says the doors on the Porsche used "side door reinforcement bars that lacked adequate welds and consisted of material weaker in strength than what is used in popular mass-market cars ... designed and built to be operated at speeds much slower than the Carrera GT."

 Last year's sheriff's investigation came to some additional conclusions. 
 
 Walker and friend Roger Rodas, 38, had no drugs or alcohol in their blood. Both men were wearing seat belts. The airbags deployed as they should have when the car clipped a light pole and several trees, investigators said. 
 
 Nothing mechanical went wrong to cause the Porsche to leave the wide road. Investigators found "no pre-existing conditions that would have caused this collision," the report said. Experts from Porsche and Michelin were consulted 
 
 Walker and Rodas, racing team partners, left a charity event at a car shop co-owned by the men to take a ride in an office park in the community of Valencia in Santa Clarita, about 30 miles north of Hollywood. The crash happened a few hundred yards away on a wide street. 
 
 An autopsy revealed "scant soot" in Walker's trachea, suggesting his life ended before the smoke and fire engulfed the car. 
 
 The actor's body was badly burned "and in a pugilistic stance. His right wrist was fractured and his left arm was fractured," the report said. Rodas was also described as in "a pugilistic" -- or defensive -- position.

 Walker suffered fractures of his left jawbone, collarbone, pelvis, ribs and spine, the report said. 
 
 Rodas "rapidly died of severe blunt head, neck and chest trauma," the report said. ||||| FILE - This March 21, 2013 file photo shows U.S. actor Paul Walker wearing a creation from the Colcci summer collection at Sao Paulo Fashion Week in Sao Paulo, Brazil.

 LOS ANGELES (AP) — The widow of a man driving the Porsche that crashed and killed actor Paul Walker cannot prove the carmaker is responsible for the accident, a federal judge said. 
 
 There was not enough evidence in Kristine Rodas' claims that her husband died because the Porsche Carrera GT he was driving lacked several key safety features, U.S. District Judge Philip S. Gutierrez ruled Monday. 
 
 He said there was no evidence the Porsche's suspension failed before the crash, as Rodas' lawsuit claimed. She also had alleged the rare sports car lacked a crash cage and fuel cell. 
 
 "Plaintiff has provided no competent evidence that Rodas' death occurred as a result of any wrongdoing on the part of defendant," Gutierrez wrote. 
 
 Walker was riding in the Carrera GT driven by his friend Roger Rodas when the car spun out of control, struck three trees and burst into flames on a street in Santa Clarita in November 2013. Walker was on a break from filming the seventh installment of the "Fast & Furious" franchise when he died. 
 
 The ruling has no bearing on two other cases against Porsche filed by Walker's daughter and father, which are both pending in Los Angeles Superior Court. 
 
 Meadow Walker's attorney said in a statement that while Rodas was killed instantly in the crash, Walker was still alive when the car caught fire. 
 
 "Meadow will continue the fight to hold Porsche accountable for selling a defective product that kills," attorney Jeff Milam wrote. 
 
 Porsche has denied wrongdoing in the design, manufacture or marketing of the Carrera GT. The company also contended in the lawsuit by Walker's daughter that the car had been altered and improperly maintained and that those factors contributed to the crash. 
 
 An email to Porsche seeking comment was not immediately returned Tuesday. 
 
 An investigation by the Los Angeles County Sheriff's Department and California Highway Patrol concluded that unsafe speed, not mechanical problems, caused the crash. Investigators said the Porsche was going up to 94 mph (151 kph) when it crashed. 
 
 Engineers from Porsche, who evaluated the wreckage of the rare car, helped in the investigation. 
 
 All the cases against Porsche contend the car was going much slower before it spun out of control. The Walkers' suits say the vehicle was traveling between 63 and 71 mph (101 to 114 kph). 
 
 Kristine Rodas sued over the crash in May 2014. Her attorney, Mark Geragos, said Tuesday that the ruling will be appealed. 
 
 Gutierrez faulted Rodas' expert for initially relying on an analysis of tire marks taken a month and a half after the fatal crash rather than photos investigators took at the scene. 
 
 After Walker's death, his two brothers helped complete action scenes in "Furious 7," which earned more than $1.5 billion globally when it was released in April.

– Just days after a judge ruled that Porsche is not liable for Paul Walker's death in a 2013 crash, bittersweet news for the actor's daughter: Meadow Walker has been awarded a $10.1 million settlement from the estate of Roger Rodas, who was driving the Porsche Carrera GT that crashed, killing both Rodas and Walker. The lawyer for Meadow, 17, says the amount is just "a fraction of what her father would have earned as an international movie star had his life not tragically been cut short," People reports. Meadow has filed her own lawsuit against Porsche, which is continuing. (Click to see Meadow's touching tribute to her dad.)
