Opinion

OPINION AND ORDER

HOLMES, District Judge.

Ann Kennedy has filed a crossclaim against General Motors in which she alleges that the accident at issue in this case was caused by a defect in the pickup truck that she was driving when the accident occurred. Her lawyers have engaged Drs. Jahan Rasty and Dale Wilson as expert witnesses to testify regarding the alleged defect. General Motors has moved to exclude the testimony of Rasty and Wilson pursuant to Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), and for summary judgment. Both parties have submitted affidavits and deposition transcripts, thoroughly briefed the issues, and presented evidence and argument at a Daubert hearing. After careful consideration of the evidence and arguments, the Court excludes the testimony of Rasty and Wilson as unreliable but denies summary judgment in favor of General Motors.

I.

On July 24, 2002, Kennedy was driving a 2001 Chevrolet Silverado westbound on Interstate Highway 40 when she lost control of the vehicle, crossed the center median, and struck two other vehicles. Kennedy testified that the Silverado began weaving, that she suddenly lost the ability to control the direction of the vehicle, and that the vehicle then shot across the median. Her husband, Thomas Kennedy, who was in the vehicle with her, testified that he saw the right front fender go down and then come up. Next, he saw the left front fender go down “markedly,” followed again by the right side. He testified that each time a side went down, it went down further and “got worse.” He testified that when the right side went down, the front end of the Silverado moved toward the right; when the left side went down, the front end of the vehicle moved towards the left. Mr. Kennedy told his wife during this process not to oversteer, but after the right dip, left dip, and another right dip, the vehicle “took off across the median.”

Kennedy claims that her vehicle’s left torsion bar adjuster, which is part of the suspension system, was defective. 1 A suspension system functions to isolate vehicle occupants from road surface irregularities and, although it is distinct from the steering system, contributes to the ride and handling characteristics of the vehicle. The Silverado’s front suspension system was a torsion bar suspension system. The torsion bar, which is a steel or steel composite shaft, functions as a spring in the suspension system and controls the vertical position of the suspension. It is connected from a lower control arm to an adjustable mount at the torsion bar cross member. A hexagonal hole of the lower control arm accepts the hexagonal-shaped front end of the torsion bar; the torsion bar adjuster receives and secures the hexagonal-shaped back end of the torsion bar; and the torsion bar cross member houses the torsion bar adjuster. The torsion bar adjuster allows adjustment of the ride height of each side’s front suspension in order to ensure level height at rest.

Either before or during the accident, the left-side torsion bar adjuster was broken into two pieces along a vertical plane at the six o’clock and twelve o’clock positions of the hexagonal hole. A piece of the *1027 fractured torsion bar adjuster in the shape of a “y” was recovered; the remaining “u” shaped piece was never found. 2

The experts disagree as to how and when the torsion bar adjuster broke. General Motors’ experts say that it broke due to impact forces from the accident. Kennedy’s experts, Rasty and Wilson, say that some unspecified manufacturing or material defect in the torsion bar adjuster induced a fracture along the hexagonal hole which, in turn, caused the torsion bar adjuster to break under normal operating forces. Rasty and Wilson say that the fracture originated in the lower portion of the torsion bar adjuster at the six o’clock position of the hexagonal hole. According to their testimony, the torsion bar adjuster was completely fractured at the six o’clock position of the hexagonal hole and partially fractured at the twelve o’clock position for a significant period of time before the accident, at least weeks but possibly months, and that the torsion bar adjuster completely fractured at the twelve o’clock position immediately before the accident, which caused the torsion bar adjuster to break into two pieces. Rasty offers the additional opinion that the fracture at the twelve o’clock position caused the accident. He says that the final fracture of the torsion bar adjuster meant that the torsion bar adjuster would no longer support the weight of the truck, which shifted the center of gravity of the truck to the left and caused Kennedy to lose control. 3

II.

Rasty is an associate professor of mechanical engineering at Texas Tech University. He teaches mechanical metallurgy and fracture and failure analysis, among other things. Wilson is a professor of mechanical engineering at Tennessee Tech University. He researches in the areas of fracture analysis and failure mechanics, among other things. Except for Rasty’s qualification to opine that the fracture of the torsion bar caused the accident, General Motors does not dispute the qualifications of Rasty and Wilson to testify as experts in the area of failure analysis. General Motors does, however, contend that their testimony should be excluded under Daubert.

“The opinion of a qualified expert witness is admissible if (1) it is based upon sufficient facts or data, (2) it is the product of reliable principles and methods, and (3) the expert has applied the principles and methods reliably to the facts of the case.” Fireman’s Fund Ins. Co. v. Canon U.S.A., Inc., 394 F.3d 1054, 1057 (8th Cir.2005) (citing Fed.R.Evto. 702). The inquiry “entails a preliminary assessment of whether the reasoning or methodology underlying the testing is scientifically valid and of whether the reasoning or methodology properly can be applied to the facts in issue.” Daubert, 509 U.S. at 592-93, 113 S.Ct. at 2796. “Ordinarily, a key question to be answered ... will be whether [a theory] can be (and has been) tested.” Id. at 593, 113 S.Ct. at 2796. Scientific methodology is “based on generating hypotheses and testing them to see if they can be falsified; indeed, this methodology is what distinguishes science from other fields of human inquiry.” Id. (internal quotation marks and citations omitted). Other factors may include: whether the theory has been subjected to peer review and publication; what the known or potential rate of *1028 error is; the existence and maintenance of standards controlling the technique’s operation; whether the theory has received “general acceptance” in the relevant scientific community, whether the expertise was developed for litigation or naturally flowed from the expert’s research; whether the proposed expert ruled out alternate explanations; and whether the expert sufficiently connected the proposed testimony with the facts of the case. Id. at 593-94, 113 S.Ct. at 2797; Lauzon v. Senco Prods., Inc.,
