IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

SIXTH APPELLATE DISTRICT

MALLORY HARCOURT, H052308 (Santa Clara County Plaintiff and Appellant, Super. Ct. No. 19CV358488)

v.

TESLA, INC.,

Defendant and Respondent.

In 2018, four days after purchasing a Tesla Model X SUV, Mallory Harcourt was injured when she left her key fob in the car, her two-and-half-year-old son climbed in, he started the car, and the car slammed into her. Harcourt sued Tesla, Inc. (Tesla), claiming a design defect allowed the child to start the car. Before trial, she decided to rely solely on the consumer expectations test to prove the alleged defect. After Harcourt rested, Tesla filed a motion for a nonsuit, which the trial court granted on the ground that Harcourt had not shown that the consumer expectations test—which is reserved for cases where ordinary users have “commonly accepted minimum safety assumptions” about a product (Soule v. General Motors Co. (1994) 8 Cal.4th 548, 569 (Soule))—applies in this case. As explained below, we agree and affirm. I. BACKGROUND A. The Incident

On December 23, 2018, Harcourt, who was then eight-and-a-half months pregnant, purchased a Model X. Four days later, she parked the car in her driveway. Leaving her purse with the key fob for the car in the car, Harcourt took B.H., her two- and-a-half-year-old son, out of his car seat and proceeded with him toward the house. Finding she did not have her house key, Harcourt returned with B.H. to the car, but before finding the key she realized that B.H.’s diaper needed to be changed. Harcourt therefore opened the driver’s side rear car door to retrieve the diaper bag and the driver’s door to press the garage door opener. Leaving both car doors open—and the key fob in the car— Harcourt and B.H. walked toward the garage so that Harcourt could change his diaper there. As Harcourt began setting up the changing pad, she realized that B.H. was not with her and that the Model X was moving toward her. Harcourt pivoted toward the vehicle in an effort to make it “see her” and stop. However, the front bumper struck Harcourt on the bottom of her abdomen, picked her up, and pushed her back until it pinned her against the wall. Harcourt suffered fractures to her leg and pelvis, as well as a traumatic wound to her leg and soft tissue damage. Approximately a week later, labor was induced, and Harcourt gave birth to a daughter, who was uninjured. After Harcourt was hit, she saw B.H. pop up inside the Model X. The car’s data logs showed that B.H., who apparently had climbed inside, pressed the brake pedal, which caused the driver’s side door to close. B.H. then shifted the car into drive by simultaneously pressing the brake pedal and moving the gear selector stalk on the side of the steering wheel column, released the brake pedal, and pressed the accelerator pedal. The car began moving, increasing speed to three miles per hour, but slowed to nearly a stop before increasing speed again to eight-and-a-half miles per hour before again slowing. The car was traveling approximately six to seven miles per hour when it

2 impacted Harcourt. Three seconds after the impact, the car auto shifted into park. Approximately a minute later, B.H. again pushed the accelerator pedal, but the car remained in park and did not move further. B. The Model X The Model X was unusual in several respects. Unlike most cars, the Model X was not equipped with a start/stop button. Instead, the driver’s door would open if a user approached with the key fob, and once the key fob was inside, the car would turn on. Thus, a driver did not need to press a button or insert a key into the ignition to start the car; instead, if the key fob was in the car, a driver could start it by pressing the brake pedal and shifting the car into gear. The gear shifter was similar in size and location to a windshield wiper, which a driver would click up or down to shift the car into reverse or drive. The car also was equipped with several safety features. Among these was a PIN- to-Drive feature, which, once set up, required an operator to enter a 4-digit personal identification number before driving the vehicle. Harcourt, who did not read the vehicle’s manual before the accident, testified that she was unaware of this feature before the accident but, had she known about the feature, she would have activated it. The vehicle was also equipped with an “obstacle aware acceleration” feature, which activated during the incident at issue to slow the vehicle down, a “brake override system,” which would reduce torque on the engine and prevent the vehicle from moving forward, and an “auto shift to park” feature, which would shift the vehicle into park in certain situations. Harcourt also did not know about these features. C. The Proceedings Below 1. Harcourt’s Pleadings

In May 2019, Harcourt, individually and on behalf of her two minor children, sued Tesla, asserting six causes of action, including strict product liability as well as negligence, breach of warranty, intentional misrepresentation, and consumer fraud. In

3 September 2019, Harcourt amended her complaint, dropping a statutory claim. Finally, in April 2024, after the case was called for trial, Harcourt requested and received leave to file a second amended complaint. In the second amended complaint, Harcourt was the sole plaintiff, and she asserted a single cause of action for strict product liability, alleging that her Model X injured her when it “did not perform as an ordinary consumer would have expected it to perform when used or misused in a reasonably foreseeable way.” 2. Harcourt’s Evidence

At the beginning of trial, Harcourt notified the court that she intended to assert a design defect solely under the consumer expectations test. The trial court accepted Harcourt’s “abandonment and waiver of any effort to establish liability under the risk benefit test.” The court also granted Harcourt’s request to limit evidence concerning defects to that relevant to the consumer expectations test. At trial, Harcourt testified that she left her key fob in the car, but it did not occur to her that it would be dangerous to do so or to leave the door open with her young son around. Harcourt explained that she did not believe that her son could start and operate the car “because normally you would have to get in the car, put your foot on the brakes, start the car, press the button. There is some type of thing [such as pressing a button or inserting a key into the ignition] before you are able to put it into gear . . . .” Harcourt admitted that, in the days preceding the accident, B.H. sat in the front passenger seat of a Tesla when the family was at the showroom purchasing the vehicle. She also admitted that for Christmas B.H. had received a ride-in Audi toy that a child could drive while a parent walked alongside, which included an on/off switch, a steering wheel, and a single pedal to accelerate. 3. The Motion for Nonsuit

After Harcourt rested, Tesla moved for nonsuit. Tesla argued that Harcourt had not presented evidence showing that the consumer expectations test applies to this case. In particular, Tesla argued, “[t]he ordinary consumer has no idea how the vehicle should

4 have performed once B.H. climbed into it, much less how safe the vehicle could have been made in the context of this case.” Harcourt opposed, arguing that the Model X violated ordinary consumer expectations because “[i]t allowed a two-year-old, in 2.5 seconds, to be able to move a car into his mother. Start, put in drive, and move.” The trial court observed that this contention raised questions about what features, in addition to the brake pedal and gear shifter, might be relevant to determining whether the car performed as safely as expected under the circumstances.
