Before: SUTTON, Chief Judge; MOORE and RITZ, Circuit Judges.

KAREN NELSON MOORE, Circuit Judge. Plaintiff-appellant K&M Knights Express,

Inc. (K&M) appeals from the district court’s grant of summary judgment in favor of defendant-

appellee Hullett’s Service Center, LLC (HSC). Because we agree with the district court that K&M

presented insufficient evidence of causation to survive summary judgment, we AFFIRM the

district court’s judgment.

I. BACKGROUND

In May 2021, K&M, a Georgia-based trucking company, sent one of its trucks, a 2012

Volvo semi-truck, to HSC’s shop in Manchester, Tennessee for repairs after the truck broke down

in Tennessee. R. 6 (Am. Compl. ¶¶ 2, 6–9) (Page ID #17–18); R. 51-1 (Invoice) (Page ID #106).

HSC performed several repairs.1 Most relevant for our purposes, HSC replaced the engine with a

1 On appeal, K&M does not renew its claims that HSC’s negligent replacement of the truck’s clutch and installation of the motor mount caused damage to the truck. We therefore do not reach those claims. See McPherson v. Kelsey, 125 F.3d 989, 995–96 (6th Cir. 1997) (“[I]ssues adverted to in a perfunctory manner, unaccompanied by No. 23-5932, K&M Knights Express, Inc. v. Hullett’s Serv. Ctr., LLC

used model and, to make the replacement engine fit, altered the truck’s frame. R. 55 (Statement

of Material Facts ¶¶ 1, 4) (Page ID #1020–21).2

The truck began to leak oil in June 2021. Id. ¶¶ 7–8, 12 (Page ID #1021–22). K&M

operated the truck continuously for at least 119,988 miles from June 2021 to December 2021, but

did not repair the oil leak. Id. ¶¶ 11–13 (Page ID #1022). Instead, K&M instructed its drivers to

replenish the oil and continue operating the vehicle until the engine ultimately failed on December

15, 2021. Id. ¶¶ 14–15 (Page ID #1022–23). When K&M asked mechanic Tony Douglas to assess

the truck after the final breakdown, he found that there was oil “[p]retty much kind of all over the

engine” and that the engine had “locked up” and could not be started. R. 51-9 (Douglas Dep. at

10, 12, 14) (Page ID #500, 502, 504). Douglas could not identify where the leak originated. Id.

at 13 (Page ID #503).

K&M brought this diversity suit against HSC seeking damages under state law for

negligence, breach of implied contract, and breach of implied and express warranties. R. 6 (Am.

Compl. ¶¶ 32–55) (Page ID #21–23). K&M alleged that HSC’s repair work had “irreversibly

damaged” the truck and rendered it “unsafe to drive,” id. at ¶¶ 26, 28–29 (Page ID #20), and argued

that there was evidence that HSC’s alteration of the frame decreased the truck’s value, R. 56 (Opp.

to Summ. J. at 15) (Page ID #1039). K&M also argued that there was evidence that HSC’s

replacement of the engine caused the oil leak and ultimate engine breakdown. Id. at 17 (Page ID

#1041). After discovery, HSC filed a motion for summary judgment on each claim, which the

some effort at developed argumentation, are deemed waived.” (quoting Citizens Awareness Network, Inc. v. U.S. Nuclear Regul. Comm’n, 59 F.3d 284, 293–94 (1st Cir. 1995))). 2 The parties dispute whether HSC altered the frame by cutting it or by grinding it. R. 55 (Statement of Material Facts ¶ 4) (Page ID #1021). The difference is not material for our purposes.

2 No. 23-5932, K&M Knights Express, Inc. v. Hullett’s Serv. Ctr., LLC

district court granted in full. R. 83 (Op. and Order) (Page ID #1741); K&M Knights Express, Inc.

v. Hullett’s Serv. Ctr., LLC, No. 4:22-CV-00015, 2023 WL 6429640 (E.D. Tenn. Oct. 2, 2023).

The district court found that there was no dispute of material fact as to the causation

element of K&M’s claims. As relevant on appeal, K&M had “failed to present any evidence beyond

‘metaphysical doubt’ that the value of the truck was decreased due to Defendant’s alteration of the

frame.” K&M Knights Express, Inc., 2023 WL 6429640, at *3. And, K&M had “failed to put forth

any facts showing that [HSC’s allegedly negligent installation of the used engine] caused the

breakdown of the engine. Rather, the record is clear that no one, not even Plaintiff’s expert, knows

why the engine seized up in December 2021.” Id. at *4. On appeal, K&M argues that the district

court erred by improperly weighing the credibility of its evidence and argues that this evidence,

when construed in K&M’s favor, created a dispute of material fact about whether HSC’s work

caused K&M’s alleged injuries.

II. ANALYSIS

A. Standard of Review

We review de novo a district court’s grant of summary judgment. Tepper v. Potter, 505

F.3d 508, 513 (6th Cir. 2007). Under Federal Rule of Civil Procedure 56(a), summary judgment

is proper “if the movant shows that there is no genuine dispute as to any material fact and the

movant is entitled to judgment as a matter of law.” “Where the record taken as a whole could not

lead a rational trier of fact to find for the non-moving party, there is no ‘genuine issue for trial.’”

Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587 (1986) (quoting First Nat’l

Bank of Ariz. v. Cities Serv. Co., 391 U.S. 253, 289 (1968)). To defeat summary judgment, an

3 No. 23-5932, K&M Knights Express, Inc. v. Hullett’s Serv. Ctr., LLC

“opponent must do more than simply show that there is some metaphysical doubt as to the material

facts.” Id. at 586.

B. Causation

The parties and district court apply Tennessee law to K&M’s common-law claims and,

accordingly, we do the same. Causation is an essential element of each of K&M’s claims. See

McClenahan v. Cooley, 806 S.W.2d 767, 774 (Tenn. 1991) (negligence); ARC LifeMed, Inc. v.

AMC-Tenn., Inc., 183 S.W.3d 1, 26 (Tenn. Ct. App. 2005) (breach of contract); Smith v. TimberPro

Inc., No. W2018-00878, 2019 WL 238113, at *5 (Tenn. Ct. App. Jan. 17, 2019) (breach of

warranty). To show causation under Tennessee law, “[t]he plaintiff must introduce evidence which

affords a reasonable basis for the conclusion that it is more likely than not that the conduct of the

defendant was a cause in fact of the result. A mere possibility of such causation is not enough;

and when the matter remains one of pure speculation or conjecture or the probabilities are at best

evenly balanced,” no reasonable basis for a finding of causation exists. Lindsey v. Miami Dev.

Corp., 689 S.W.2d 856, 861 (Tenn. 1985) (quoting William L. Prosser & W. Page Keeton, Torts

§ 41 (5th ed. 1984)); see Jenkins v. Big City Remodeling, 515 S.W.3d 843, 852 (Tenn. 2017)

(holding that defendant-contractors were entitled to summary judgment on claim that their

negligence caused a fire because evidence that defendants handled flammable substances and

smoked cigarettes in the area of the fire did not “link these alleged acts to the fire” and could not

establish causation).

In its motion for summary judgment, HSC argued, as it does before us now, that there was

no record evidence affirmatively showing that HSC’s alteration of the truck’s frame caused any

damage to the truck or decrement in its value. R. 51 (Mot. for Summ. J. at 14–17) (Page ID #96–

4 No. 23-5932, K&M Knights Express, Inc. v. Hullett’s Serv. Ctr., LLC

99). To the contrary, HSC pointed out, it was undisputed that K&M operated the truck safely for

six months after discovering that HSC had altered the frame. Id. And, HSC pointed to evidence

that K&M’s witnesses did not know what caused the oil leak or the engine’s ultimate breakdown.

Id. at 8 (Page ID #90). K&M argues that there is a dispute of material fact as to causation, relying

on witness testimony amounting to speculation and conjecture that HSC’s repairs could have

caused K&M’s alleged injuries. Faced with the other record evidence, a rational trier of fact could

not find by a preponderance of the evidence that HSC caused injury to K&M. The district court

correctly granted HSC’s motion for summary judgment.

1. The Frame

K&M argues that the district court erred when it found that K&M had produced no

evidence that HSC’s alterations to the truck’s frame caused K&M’s alleged injuries. On appeal,

K&M argues it has produced evidence of causation, including in the form of testimony by

mechanic Tony Douglas. Appellant Br. at 19. But Douglas testified only about the possible effects

of the frame alteration and did not opine as to what effect the frame alteration actually had on the

value of K&M’s truck. Douglas testified that it “would be kind of hard for [him] to say if [the

frame alteration] raised [a] safety issue or not” but that he thought it “could have possibly . . .

eventually caused that frame to actually crack or break” in the area where it had been altered. R.

51-9 (Douglas Dep. at 21–22) (Page ID #511–12). As to the impact of the frame alteration on the

specific vehicle in question, when prompted by K&M’s attorney, Douglas suggested that K&M

“may be able to sell [the truck] at a lesser value” because of the alteration. Id. at 22 (Page ID

#512). Douglas engaged in conjecture and speculation about the possible effects of frame

alteration, but he did not opine about whether the frame alteration in fact caused K&M’s alleged

5 No. 23-5932, K&M Knights Express, Inc. v. Hullett’s Serv. Ctr., LLC

injuries. This evidence, without more, could not support a jury verdict in K&M’s favor. See

Lindsey, 689 S.W.2d at 861.

The other evidence that K&M proffers in support of its frame theory is not relevant to the

issue of causation. K&M points to mechanic Tremarcus Williams—a lay witness who had

examined the truck’s frame after HSC worked on it—who testified that it “would definitely be

inappropriate” to alter a truck’s frame as HSC did, noting that manufacturers put labels on truck

frames instructing mechanics not to cut truck frames because cutting frames “weakens the metals.”

R. 51-10 (Williams Dep. at 8–10, 13) (Page ID #543–45, 548). But, Williams concluded, he

“really [couldn]’t say or answer [the] question” of whether altering the frame “would have any

effect on the truck itself in any way.” Id. at 13 (Page ID #548). Tom Ward, who K&M proffered

as an expert witness,3 opined generally that cutting the frame went “against the truck

manufacturer’s guidelines,” as well as the stickers and warnings on the frame itself. R. 51-11

(Ward Dep. at 32–33, 40) (Page ID #593–94, 601). Ultimately, the Williams and Ward testimony

that a mechanic should not alter a truck’s frame is evidence that a mechanic who does so is

negligent, but it is not evidence that the mechanic’s negligence caused any injury. See Jenkins,

515 S.W.3d at 852 (“Proof of negligence without proof of causation is nothing.” (quoting King v.

Anderson County, 419 S.W.3d 232, 247 (Tenn. 2013))).

3 HSC asserts that K&M failed timely to disclose Ward as an expert, that Ward is unqualified and unreliable, and that his opinion relies on improper legal conclusions. Appellee Br. at 38–51 (incorporating R. 53 (Mot. to Exclude Ward) (Page ID #630)). We need not reach these arguments because, even if Ward’s testimony were proper expert testimony, it could not support a jury finding that HSC’s alteration to the truck’s frame caused K&M’s alleged injuries.

6 No. 23-5932, K&M Knights Express, Inc. v. Hullett’s Serv. Ctr., LLC

2. The Engine Replacement

K&M next argues that it presented sufficient evidence to create a jury question about

whether HSC’s replacement of the engine caused an oil leak, and whether the leak in turn caused

the engine to seize up. For this assertion, K&M relies almost exclusively on testimony by Douglas

that, when rebuilding an engine, “the process is to replace all seals and everything that oil pressure

is subject to, which would actually create that leak if there was components that wasn’t replaced.”

R. 51-9 (Douglas Dep. at 23) (Page ID #513); see Appellant Br. at 25–26.

Douglas’s testimony, however, cannot support a finding by a reasonable jury that HSC’s

replacement of the engine caused the oil leak or the truck’s final breakdown. Douglas expressly

disclaimed an opinion on causation, saying he “[did]n’t know what the specific cause of the

[engine] failure [was].” R. 51-9 (Douglas Dep. at 15–16) (Page ID #505–06). When asked directly

if he believed that HSC was “negligent or made mistakes in th[e] [engine] installation which

resulted in” the oil leak, Douglas testified that he “[could]n’t actually say per se what [HSC] . . .

did or didn’t do to that engine and why it would actually have those oil leaks,” and that he “[did]n’t

have a real opinion” about what caused the engine to seize up. Id. at 24–25 (Page ID #514–15).

A reasonable jury, faced with Douglas’s express disavowal of any opinion on the cause of the oil

leak or engine failure, could not find by a preponderance of the evidence that HSC’s replacement

of the engine caused either the leak or the engine failure. The district court did not err by granting

HSC’s motion for summary judgment.

III. CONCLUSION

For the foregoing reasons, we AFFIRM the district court’s judgment.
