Opinion by Justice ELIZABETH A. McCLANAHAN.
In this products liability action, Hyundai Motor Company, Ltd., and Hyundai Motor America, Inc. (Hyundai) appeal from a judgment entered on a jury verdict in favor of Keith Allen Duncan and Vanessa Duncan, Guardians and Conservators for Zachary Gage Duncan (Gage), and Keith Allen Duncan and Vanessa Duncan, Individually.
Gage sustained a serious closed-head injury while driving his 2008 Hyundai Tiburon when he lost control of the vehicle, causing the vehicle to leave the road, strike two snow banks and a large bale of hay, before ultimately colliding with a tree on the driver's side of the vehicle. Although the Tiburon was equipped with a side airbag system, the airbag did not deploy.
The Duncans brought an action against Hyundai, which manufactured and distributed the 2008 Tiburon being driven by Gage, and initially asserted claims for negligence, failure to warn, breach of implied warranty of merchantability, breach of implied warranty of fitness for a particular purpose, and breach of express warranties. At trial, the Duncans pursued only their claim for breach of implied warranty of merchantability in which they assert that the "Tiburon was defective, unreasonably dangerous, was not fit for the ordinary purpose for which it was intended, and did not pass without objection in the industry in which it was sold." Specifically, the Duncans contend that if the sensor for the side airbag system had been placed in a different location, the airbag would have deployed and prevented Gage's injury.
To support their claim, the Duncans designated Geoffrey Mahon (Mahon), a mechanical engineer, as an expert in airbag design to testify that the 2008 Hyundai Tiburon was defectively designed. Mahon expressed the opinion that if Hyundai had located the sensor for the side airbag system on the B-pillar of the vehicle (the pillar where the front door closes), approximately 4 to 6 inches from the floor, instead of on the cross-member underneath the driver's seat, the side airbag would
Prior to trial, Hyundai moved to exclude Mahon's opinions as having an insufficient foundation because Mahon did not conduct any analysis to determine whether the side airbag would have deployed if the sensor had been located where Mahon proposed.
When deposed, Mahon testified that in reaching his opinion, he relied upon a computer-aided engineering study conducted by Hyundai in 1999 in which Hyundai analyzed 14 potential locations for the side airbag sensor, including a location on the B-pillar that was 10 to 12 inches from the floor.
While Mahon believed the best location for the sensor was at the B-pillar, he testified he did no testing to determine if the side airbag would have deployed in Gage's accident had the sensor been placed at any other location.
(Emphasis added.) The circuit court denied Hyundai's motion to exclude Mahon's testimony, and he was permitted to express his opinions at trial, over Hyundai's objections.
At trial, Mahon testified that Hyundai was not required under Federal Motor Vehicle Safety Standards (FMVSS) to install a side-impact airbag system in the 2008 Tiburon, and that the 2008 Tiburon would have complied with the FMVSS for side impact protection without any side airbag system.
Mahon's initial impression of the airbag system was that "the airbag should have gone off," but upon further investigation, he concluded that the system was acting as designed "so this indicates that it was designed improperly, because this is a crash where you really need an airbag." Mahon agreed that the 2008 Tiburon, with the side airbag system, complied with FMVSS 214, the standard specifically related to side impact protection. He further acknowledged that the 2008 Tiburon "did reasonably well" when Hyundai conducted 22 crash tests in which it ran the vehicle into different types of barriers, at different speeds and angles, with the side
In Mahon's opinion, however, the side airbag would have deployed in Gage's accident if the sensor for the side airbag system had been located on the B-pillar, approximately 4 to 6 inches from the floor. According to Mahon, this was true even though the sensor on the cross-member underneath the driver's seat was closer to the point of impact than it would have been if the sensor had been located in the B-pillar because Hyundai's 1999 location study showed that there was a much better signal on the B-pillar.
Consistent with his deposition testimony, Mahon testified at trial that he did not perform an analysis to determine whether the side airbag in the 2008 Tiburon would have deployed if the sensor was in a different location but relied upon the results of the location study undertaken by Hyundai in 1999. Mahon conceded that the location on the B-pillar considered by Hyundai was located 10 to 12 inches from the floor, and he had no data demonstrating the performance of a sensor located on the B-pillar 4 to 6 inches from the floor. He further agreed that because the airbag system must work quickly, that is the sensor system must decide within 15 milliseconds of a crash event whether an airbag is required and then inflate the airbag in 15 to 50 milliseconds, the location of the sensor is important to the overall crash sensing system such that inches, and even increments smaller than inches, matter in the determination of the location of the sensor.
Though Mahon testified that the vehicle's crash sensing system is "a combination of the structure of the vehicle, the sensors themselves, and then any algorithm ... working together to make a decision whether or not this event is worthy of an airbag," he acknowledged that he had not performed any tests to determine whether any different sensor location, structure, or mathematical algorithm would have caused the side airbag to deploy in Gage's crash.
(Emphasis added.) Relying instead on his "industry experience," Mahon testified that the data in Hyundai's location study "spoke to [him] ... [a]s one skilled in the art."
On appeal, Hyundai argues there was an insufficient foundation for Mahon's opinion that the location of the sensor for the side airbag system rendered the 2008 Tiburon
Expert opinion may be admitted to assist the fact finder if such opinion satisfies certain requirements, "including the requirement of an adequate factual foundation." Forbes v. Rapp, 269 Va. 374, 381, 611 S.E.2d 592, 596 (2005); see Va.Code §§ 8.01-401.1 and -401.3; Va. R. Evid. 2:702 and 2:703; Countryside Corp. v. Taylor, 263 Va. 549, 553, 561 S.E.2d 680, 682 (2002). Since we review the circuit court's evidentiary rulings using an abuse of discretion standard, we will reverse the circuit court's decision to admit evidence only upon a finding of abuse of that discretion. John Crane, Inc. v. Jones, 274 Va. 581, 590, 650 S.E.2d 851, 855 (2007). A circuit court, though, "has no discretion to admit clearly inadmissible evidence." Harman v. Honeywell Int'l, Inc., 288 Va. 84, 92, 758 S.E.2d 515, 520 (2014).
As we have stated, "[q]ualification of an expert witness does not insure admission of his every statement and opinion." Swiney v. Overby, 237 Va. 231, 233, 377 S.E.2d 372, 374 (1989). While Code § 8.01-401.1 allows an expert to express an opinion without initially disclosing the basis for the opinion, "[w]e have never, however, construed that section to permit the admission of expert testimony that lacks evidentiary support." Vasquez v. Mabini, 269 Va. 155, 159, 606 S.E.2d 809, 811 (2005). Expert opinion must be premised upon assumptions that have a sufficient factual basis and take into account all relevant variables.
CNH America LLC v. Smith, 281 Va. 60, 67, 704 S.E.2d 372, 375 (2011) (quoting Vasquez, 269 Va. at 160, 606 S.E.2d at 811).
Mahon's opinion that the 2008 Tiburon was unreasonably dangerous was premised upon his assumption that the side airbag would have deployed if the sensor had been located on the vehicle's B-pillar. Yet, as Mahon readily conceded, he did not perform any analysis or calculations to support this assumption. In fact, Mahon admitted that the crash sensing system depends upon a combination of the structure of the vehicle, the sensors themselves, and any algorithm, but he did not perform any tests to determine whether a different sensor location, structure, or algorithm would have caused the side airbag to deploy in Gage's crash. Furthermore, despite his testimony that inches, and even increments smaller than inches, matter when choosing the sensor location, his proposed location was more than four inches from any location studied by Hyundai.
In short, Mahon's opinion that the 2008 Tiburon was unreasonably dangerous was without sufficient evidentiary support because it was premised upon his assumption that the side airbag would have deployed if the sensor was at his proposed location — an assumption that clearly lacked a sufficient factual basis and disregarded the variables he acknowledged as bearing upon the sensor location determination. Although experts may extrapolate opinions from existing data, a circuit court should not admit expert opinion "which is connected to existing data only by the ipse dixit of the expert." General Elec. Co. v. Joiner, 522 U.S. 136, 146, 118 S.Ct. 512, 139 L.Ed.2d 508 (1997) (decided under the version of Fed.R.Evid. 702 which the General Assembly adopted, verbatim, in current Code § 8.01-401.3(A)). Mahon's opinion that the vehicle was unreasonably dangerous was based on his ipse dixit assumption that the side airbag would have deployed
The Duncans relied upon Mahon's opinion that the 2008 Tiburon was unreasonably dangerous to satisfy their burden of proving that Hyundai breached its implied warranty of merchantability.
For the foregoing reasons, we will reverse the judgment of the circuit court and enter final judgment for Hyundai.
Reversed and final judgment.
Justice POWELL, dissenting.
I disagree with majority's conclusion that the opinion of Geoff Mahon, the plaintiff's expert, lacked an adequate foundation and should have been struck. In my opinion, the majority reaches this conclusion by improperly focusing on Mahon's preferred location for the side airbag sensor, even though it is clear that he did not base his conclusion on this preferred location. In so doing, the majority fails to view Mahon's testimony in the light most favorable to the Duncans, the prevailing party below. See Dagner v. Anderson, 274 Va. 678, 681, 651 S.E.2d 640, 641 (2007) (viewing the evidence in the light most favorable to the prevailing party below when reviewing whether the trial court erred in allowing expert testimony).
On direct examination Mahon clearly relied on the findings of Hyundai's 1999 location study and his calculations from the crash severity analysis to determine that the airbag would have deployed if the sensor was in the specific location
Using the signal strength data contained in the 1999 location study, he extrapolated that the airbag did not deploy because the sensor did not receive a strong enough signal due to its location on the cross member. Specifically, he opined that the cross member was too far "inboard" and not rigid enough to receive the necessary signal. He went on to determine that, because the B-pillar was a more rigid structure, located in the crush zone, a sensor placed there would receive a stronger signal, resulting in airbag deployment. Thus, in Mahon's expert opinion, the B-pillar Location would have resulted in airbag deployment in the present case.
The majority, however, never addresses any of this testimony by Mahon. Indeed, notwithstanding the fact that almost all of Mahon's testimony related to sensor placement in a specific location on the B-pillar, i.e., the location on the B-pillar subject to testing in the 1999 location study, the majority characterizes this testimony as disregarding "the variables ... bearing upon the sensor location determination." Instead, the majority focuses on statements by Mahon relating to what he believed would be the ideal location for a side airbag sensor in the 2008 Tiburon. Specifically, the majority focuses on the testimony that Mahon believed that the ideal location for the airbag sensor would be on the B-pillar, approximately four to six inches from the floor (hereafter referred to as the "Proposed Location").
It is important to note, however, that there was no mention of the Proposed Location during Mahon's direct examination. Rather, it is on cross-examination that the idea of placing the sensor in the Proposed Location was first brought up at trial. Even then, the Proposed Location was only brought up after Hyundai's attorney confirmed that Mahon's prior testimony about the B-pillar Location was based on the 1999 location study.
The majority also relies on Mahon's testimony where he "admits" that he had not done any tests or calculations showing that placing the sensor in another location would have resulted in the airbag deploying. In my opinion, however, this testimony is taken completely out of context. The testimony cited by the majority is clearly in reference to the Proposed Location, not the B-pillar Location studied by Hyundai. Indeed, it is particularly telling that the quoted exchange takes place immediately after the discussion of the Proposed Location. Thus, placed in the proper context, it is clear that Mahon was admitting that he had not performed any tests to determine whether the Proposed Location would have caused the side airbag to deploy in Gage's crash. Moreover, this "admission" is rebutted by Mahon's lengthy testimony about the calculations he performed as part of his crash severity analysis. With regard to the B-pillar Location, Mahon consistently maintained that, based on Hyundai's own study and his calculations in the crash severity analysis, a sensor placed on the B-pillar in the location tested by Hyundai in the 1999 location study would have deployed in this accident.
"Expert testimony is inadmissible if it is speculative or founded on assumptions that have an insufficient factual basis." John v. Im, 263 Va. 315, 320, 559 S.E.2d 694, 696
That said, I would still reverse the decision of the trial court. In my opinion, the trial court erred in refusing to give Hyundai's Proposed Jury Instruction 21.
Smith v. Kim, 277 Va. 486, 491, 675 S.E.2d 193, 196 (2009) (citations and internal quotation marks omitted).
Hyundai's Proposed Jury Instruction 21 is an accurate statement of the law. Indeed, it does not inform the jury that Hyundai's compliance with the Federal Motor Vehicle Safety Standards ("FMVSS") was dispositive. Rather, it merely provides the jury with a guide for determining whether the Tiburon was reasonably safe or unreasonably dangerous. Furthermore, as the United States Court of Appeals for the Fourth Circuit has recognized, evidence relating to a manufacturers compliance with the FMVSS is "relevant and necessary" to demonstrate a company's care in bringing a product to market. S.L.M. v. Dorel Juvenile Group, Inc., 514 Fed.Appx. 389, 392 (4th Cir.2013) (approving a similar instruction relating to a different FMVSS standard). Therefore, I would reverse the trial court's judgment based upon its refusal to give Hyundai's Proposed Jury Instruction 21 and remand the case for retrial.
