The driver of a car involved in an accident sued the dealer and manufacturer 

of the car for negligence and breach of warranty, alleging the vehicle was defective 

and the defect caused the accident. The dealer and manufacturer have moved for 

summary judgment on the basis that the driver failed to present an expert opinion 

regarding the existence of a defect and whether it proximately caused the accident. 

The driver contends an expert opinion is not necessary in this case because she has 

offered circumstantial evidence of a defect that negates other reasonable causes of 

the accident. The question before the Court is whether the evidence the driver has 

adduced, namely her own testimony and a notice in a class action that the vehicle 

was within a class of vehicles alleged to contain such a defect, is such that this case

falls within the relatively narrow segment of cases where expert testimony is not 

necessary to prove a product defect. In my view, as explained below, the question 

is not a close one, and the driver’s failure to provide an expert opinion entitles the 

movants to summary judgment.

FACTUAL AND PROCEDURAL BACKGROUND

Unless otherwise noted, the following facts are undisputed. The plaintiff, 

Mollie L. Newcomer, alleges she sustained personal injuries and property damage 

during a car accident in which a 2010 Toyota Sienna driven by Defendant Carole 

A. Burkholder collided with Newcomer’s car. Three months after Newcomer filed 

this action, Burkholder filed third-party claims against Newark ToyotaWorld (the 
2

“Dealer”), Toyota Motor Corporation (“Toyota Corporation”) and Toyota Motor 

Sales, U.S.A., Inc. (“Toyota Sales” and collectively with Toyota Corporation, the 

“Manufacturer Defendants”).1 Unless the distinction is material, I refer to the 

third-party defendants jointly as “Toyota.”

A. The accident and the aftermath

In her complaint, Newcomer alleged that Burkholder negligently drove her 

Toyota Sienna into Newcomer’s vehicle. In her answer, Burkholder asserted

several affirmative defenses grounded in her contention that the accident was 

unavoidable and that the injuries Newcomer sustained were proximately caused by 

an intervening or superseding cause, namely a defect in Burkholder’s Toyota 

Sienna (the “Burkholder Vehicle”) that caused the vehicle to accelerate at the 

moment of the accident, even though Burkholder’s foot was on the brake and not 

on the gas.2 

Those contentions were repeated in Burkholder’s third-party complaint 

against Toyota. Specifically, Burkholder brought three claims against Toyota: one 

claim against the Dealer for negligence, one claim against the Manufacturer 

Defendants for negligence, and one claim against the Manufacturer Defendants for 

 

1 Burkholder also brought a claim against Toyota North America, Inc. According to Toyota, the 

parties agreed not to pursue any claims against that party. Defs.’ Renewed Mot. Summ. J. at 1,

breach of the implied warranty of merchantability.3 After Newcomer filed her 

complaint, but before Burkholder filed the third-party claims, Burkholder disposed 

of the Burkholder Vehicle, which has been within her control since the accident.

B. Burkholder pursues discovery.

This Court issued its initial trial scheduling order (the “Original TSO”) on

June 17, 2015, after all third-party claims and answers had been filed. The 

Original TSO set a deadline of September 15, 2015 for plaintiffs’ expert reports or 

disclosures and a deadline of December 15, 2015 for defendants’ expert reports or 

disclosures. There were no other expert deadlines in the scheduling order, nor 

were any requested by the parties. When the September 2015 deadline passed with

neither Burkholder nor Newcomer filing an expert report or disclosure supporting

their claims against Toyota, Toyota moved for summary judgment, arguing expert 

testimony was necessary to support the third-party claims against Toyota. Two 

days later, Burkholder propounded her first discovery requests directed to Toyota. 

Toyota then moved for a protective order, arguing the discovery was overbroad 

and, in any event, would be unnecessary if Toyota’s summary judgment motion 

was granted.

 

3 Newcomer later amended the complaint to add negligence claims against Toyota. Newcomer 

has not, however, pursued discovery from Toyota and does not oppose Toyota’s renewed motion 

for summary judgment. See D.I. 85, Letter to the Court from Gary Nitsche, Esquire.

At the hearing on the motion for protective order, Burkholder argued that 

discovery was necessary before she could evaluate whether retaining an expert was 

either necessary or possible.4 The Court noted the significant time that had 

elapsed, that Burkholder only now seemed to be organizing her case, and that she 

arguably5had missed the expert report deadline. The Court nonetheless reasoned 

that limited discovery should be permitted so Burkholder at least had an 

opportunity to investigate her claims before the Court considered the substance of 

the pending summary judgment motion. 

Specifically, the Court held as follows:

[W]ith respect to the pending discovery against the [M]anufacturer 

[Defendants], the motion for the protective order is stayed without 

prejudice to reconsideration after a submission by third-party 

plaintiff’s expert explaining why further discovery against the 

manufacturer is appropriate.

The motion with respect to the dealership is granted, except that the 

[D]ealer shall respond to pending discovery that relates to the car in 

question by year, make and model. Once that discovery has been 

turned over, then third-party plaintiff shall have 30 days in which to 

announce whether an expert has been retained.6

The Court’s ruling (the “Discovery Order”) permitting limited discovery and 

an extension of the expert deadline was based on a number of considerations, not 

the least of which was Burkholder’s representation that, once the requested 

 

4 Newcomer did not oppose any of the motions.

5 Burkholder argued she was a “defendant” and therefore had until December 15, 2015 to 

produce an expert report.

(TRANSCRIPT) (hereinafter “Nov. Tr.”).

discovery of the Dealer was provided, Burkholder would be in a position to decide 

whether she intended to retain an expert, without needing iterative rounds of 

discovery.7 In fact, the Court specifically held that no further discovery of the 

Toyota Defendants would be permitted unless or until Burkholder retained an 

expert, reasoning that Toyota should not have to incur additional expense until 

Burkholder made “a significant commitment to this litigation.”8

C. The schedule is revised and Toyota renews its summary judgment 

motion.

On February 22, 2016, Dealer produced the discovery required by the 

Discovery Order. The following day, Toyota asked the Court to vacate the 

Original TSO, arguing the parties could not reasonably complete discovery and 

pre-trial preparation before the June 6, 2016 trial date. None of the parties opposed 

that request, and the Court therefore vacated the Original TSO and instructed the 

parties to contact chambers to obtain new dates for trial.

Under the terms of the Discovery Order, Burkholder had until March 23, 

2016 to inform the other parties whether she had retained an expert. On March 

30th, Toyota sent a letter to Burkholder asking her to advise whether she had 

retained an expert.9 Burkholder responded by stating she had not had a chance to

review the production in detail and she would respond “early next week.”10

Burkholder did not, however, follow up with Toyota as promised. Toyota filed its 

renewed motion for summary judgment on April 29, 2016, after which the Court 

scheduled briefing and a hearing on the motion. The basis for Toyota’s motion is 

two-fold: first, Burkholder did not identify an expert within the deadline set by the 

Discovery Order and cannot maintain the claims against Toyota without expert 

testimony; and second, Burkholder disposed of her vehicle, thereby preventing the 

parties from examining the vehicle to determine whether a defect existed.

Unrelated to the motion for summary judgment, the Court issued a revised 

trial scheduling order (the “Revised TSO”) on May 27, 2016.11 That scheduling 

order established the following expert deadlines: July 15, 2016 for plaintiffs’ 

expert report or disclosures; September 16, 2016 for defendants’ expert reports or 

disclosures; and October 17, 2016 for plaintiffs’ rebuttal reports or disclosures. 

ANALYSIS

Toyota’s motion is premised on its contention that Burkholder cannot 

support her claims without expert testimony. For the sake of analytical clarity, I 

therefore address that issue first, before turning to the parties’ arguments regarding 

 

10 Id. Ex. 10.

11 Both parties attempt to draw conclusions from the timing of the Court’s issuance of the 

Revised TSO. There is no significance to the TSO or connection to the renewed motion for 

summary judgment. That process was initiated before Toyota renewed its summary judgment 

motion, see D.I. 79, and the Revised TSO was issued without any further input from the parties 

other than confirming their availability for trial.

whether Burkholder missed the expert discovery deadline or whether she is entitled 

to additional discovery before naming an expert.

Summary judgment should be awarded if “the pleadings, depositions, 

answers to interrogatories and admissions on file, together with the affidavits, if 

any, show that there is no genuine issue as to any material fact and that the moving 

party is entitled to a judgment as a matter of law.”12 When considering a motion 

for summary judgment, the evidence and the inferences drawn from the evidence 

are to be viewed in the light most favorable to the nonmoving party.13 The Court 

will accept “as established all undisputed factual assertions . . . and accept the nonmovant’s version of any disputed facts. From those accepted facts[,] the [C]ourt 

will draw all rational inferences which favor the non-moving party.”14 

A. All Burkholder’s claims against Toyota require expert testimony under 

Reybold Group, Inc. v. Chemprobe Technologies, Inc.

Toyota contends expert testimony is necessary to establish both the 

existence of a defect in the Burkholder Vehicle and that the defect proximately 

caused Burkholder’s and Newcomer’s injuries. Toyota maintains it is entitled to 

summary judgment because both those elements are required to prove 

Burkholder’s claims for negligence and breach of warranty, and Burkholder has

not proffered expert testimony, which Toyota contends is necessary to prove those 

elements. Burkholder, on the other hand, argues that this case falls within the 

exception to the rule generally requiring expert testimony because she has offered 

sufficient circumstantial evidence of a defect. 

The preliminary question is whether Burkholder must prove the existence of 

a defect to prevail on her claims. In my view, she must. Burkholder’s three claims 

against Toyota allege negligence and breach of warranty. To prevail on a claim for 

breach of the implied warranty of merchantability, Burkholder must prove: (1) 

Toyota sold the vehicle; (2) the vehicle was defective at the time of sale; (3) the 

defect caused injury to the ultimate consumer; (4) the proximate cause of the injury 

was the defective nature of the vehicle; and (5) Toyota received notice of the 

injury.15 As to Burkholder’s negligence claims, she must prove: duty, breach, 

causation, and harm.16 

Although proof of a defect is an essential element of every breach of 

warranty of merchantability case,

17 it is not always an essential element of a 

negligence claim. Here, however, proof of a defect also is a necessary element of 

Burkholder’s negligence claims. Burkholder claims the Dealer was negligent by 

failing to properly inspect and repair the vehicle’s “acceleration issues,” failing to

warn and inform Burkholder regarding the “acceleration problems,” and failing to 

train its employees to identify and resolve “known acceleration problems.” She 

contends the Manufacturer Defendants were negligent by failing adequately to 

supervise the design, manufacture, testing, and inspection of the vehicle and by 

designing a defective vehicle. Each of those contentions assumes the existence of 

a defect; if there was no defect in the Burkholder Vehicle, there was no negligence 

in designing, manufacturing, inspecting, or repairing it, or in failing to warn 

Burkholder of a danger.18 

The ultimate issue, therefore, is whether expert testimony is necessary to 

prove a defect existed in the Burkholder Vehicle’s acceleration or braking systems, 

thereby causing the accident. In Reybold Group, Inc. v. Chemprobe Technologies, 

Inc., the Delaware Supreme Court held that expert testimony typically is required 

to prove a product is defective, and always is required “[i]f the matter in issue is 

one within the knowledge of experts only and not within the common knowledge 

of laymen.”19 Even when the matter is one within the common knowledge of 

laymen, expert testimony is necessary unless the circumstantial evidence presented 

tends “to negate other reasonable causes of the injury sustained.”20

 

18 See Joseph v. Jamesway Corp., 1997 WL 524126, at * 3 (Del. Super. July 9, 1997) (“In order 

to prove a claim of negligence in the context of a products liability action alleging a 

manufacturing defect, the plaintiff must establish that the product was defective.”).

2006).

20 Reybold, 721 A.2d at 1270.
10

Although the only claim at issue in Reybold was one for breach of warranty, 

Burkholder conceded at oral argument that Reybold applies both to the negligence 

and breach of warranty claims in this case because all the claims are premised on 

the contention there was a defect in the Burkholder Vehicle.

21

 Burkholder’s claims 

do not fall within the limited set of cases Reybold identifies as not requiring expert 

testimony to establish a defect. First, the issue of unintended acceleration of a 

vehicle, including the circumstances that may cause such acceleration and whether 

those circumstances existed in particular Toyota vehicles, is not within the 

common knowledge of a layperson. To the contrary, the internal mechanical 

operations of a vehicle, and what might cause it to accelerate when – as Burkholder 

contends – the driver is applying the brakes, is a complex issue that has been the 

subject of class actions, congressional hearings, and studied debate. For that 

reason alone, the claims require support through expert testimony regarding the 

defect’s existence and its role in the accident in this case. 

In addition, even if this were an issue within the common knowledge of a 

layperson, the circumstantial evidence Burkholder offers does not tend to negate 

other reasonable causes of the injuries. The circumstantial evidence Burkholder 

contends would establish a defect is: (1) Burkholder’s testimony that she was 

 

21 Newcomer v. Burkholder, C.A. No. N14C-05-151 AML, at 31-33 (Del. Super. Aug. 15, 2016)

(TRANSCRIPT) (hereinafter “Aug. Tr.”); see also Joseph, 1997 WL 524126, at *3 (“Where a 

plaintiff is attempting to prove negligence circumstantially [in a products liability action], he 

must establish that negligence is the only possible inference.”).
11

pressing the brake before the collision, but that the car accelerated; (2) an occasion 

two years before the accident, when Burkholder contends the car accelerated 

suddenly; (3) a notice Burkholder received in connection with a class action, in 

which Toyota identified her vehicle as being among a class of vehicles alleged to 

contain a defect that could cause unintended acceleration; and (4) documents 

indicating Toyota developed processes and protocols for inspecting vehicles in 

which customers allegedly experienced unintended acceleration.22 That evidence 

is not sufficient to negate other reasonable causes of the injury, such as driver 

error. Put differently, Burkholder’s testimony about the sudden acceleration, 

protocols developed at the Dealer for the alleged problem, and a class-action legal 

notice indicating Burkholder’s vehicle was within a class of vehicles allegedly 

containing a defect is not enough to eliminate other reasonable causes of the 

collision.

Although Burkholder argued that disputed issues of material fact preclude 

summary judgment, alluding that additional facts may be available through 

discovery that would eliminate other reasonable causes of the accident, that 

argument is unconvincing for two reasons. First, Burkholder failed to file a Rule 

56(f) affidavit, as required by this Court’s rules, detailing what further discovery 

she needed in order to fairly address the motion for summary judgment. She 

 

22 Aug. Tr. 30-34.
12

therefore is precluded from relying on vague references to such additional 

discovery as a basis to deny the motion. Second, in the Discovery Order, this 

Court expressly precluded Burkholder from obtaining additional discovery from 

the Toyota Defendants until she identified her expert and provided further 

explanation, supported by her expert, regarding the need for additional discovery.23

Accordingly, Toyota is entitled to summary judgment on the third-party 

claims unless Burkholder can offer expert testimony on the issues of the existence 

of a defect and proximate cause. I therefore turn to whether Burkholder has 

waived her opportunity to offer an expert opinion by failing to identify an expert in 

a timely manner.

B. Burkholder conceded she does not intend to get an expert.

Having concluded the third-party claims require expert testimony in order to 

be presented to a jury, the question then becomes whether Burkholder has missed 

the deadlines to disclose her expert, such that Toyota’s motion for summary 

judgment should be granted. I need not address the bulk of the parties’ technical 

arguments regarding the Discovery Order, whether its deadlines were vacated, or 

the effect of the Revised TSO. I agree with Toyota that Burkholder failed to 

disclose her expert within the deadline established by the Discovery Order, which 

the Court never vacated. Nevertheless, given the general policy encouraging

 

23 Nov. Tr. 26-27, 31-32.
13

resolution of claims on their merits, the Court likely would have permitted 

Burkholder to proceed with her claims had she identified an expert at any time 

during the briefing or argument of the motion for summary judgment. Burkholder, 

however, conceded at oral argument that she will not be able to “provide an expert

opinion that says definitively that that defect existed in that vehicle as of that 

time.”24 Having conceded on the record that she will not be able to obtain the 

necessary expert support for her claim, amending the schedule to permit 

Burkholder additional time to obtain an expert would not be fruitful.

CONCLUSION

For the foregoing reasons, the Toyota Defendants’ Motion for Summary 

Judgment is GRANTED. Having concluded Toyota is entitled to summary 

judgment because Burkholder failed to provide an expert to support the existence 

of a defect, I need not reach Toyota’s alternate arguments that summary judgment 

should be granted because Burkholder failed to preserve the subject vehicle or 

because Burkholder failed to provide expert testimony regarding proximate cause.
