Plaintiff, Union Insurance Company, appeals from a judgment entered on a jury verdict denying it recovery in this product liability action brought against defendant, Radio Corporation of America (RCA). Plaintiff’s principal contention on appeal is that the trial court committed reversible error in instructing the jury pursuant to § 13-21-403(1), C.R.S. (1985 Cum.Supp.). We reverse.
In July 1974, Keith P. Holtz, plaintiff’s insured, purchased an RCA television set. In September 1976, a fire occurred in the Holtz home. In July 1977, Holtz executed a proof of loss reflecting that he had received payment on his claim against plaintiff. Plaintiff then brought suit as subro-gee of its insured, alleging that the fire *82 was caused when the TV ignited because of defects in its design and/or manufacture.
At trial, over objection by plaintiff, the jury was instructed that:
“In this case, if you find that (1) prior to any sale by RCA, the television set conformed to the state of the art, as distinguished from industry standards, and (2) such state of the art was applicable to such products as the television set at the time of such sale, then the law presumes that the television set was not defective. In this case, if you find that (1) at the time RCA made any sale of the television set, (2) it did not fail to comply with any applicable code, standard, or regulation adopted or promulgated by the United States, or by any agency of the United States, then the law presumes that the television set was not defective.
You must consider these presumptions together with all the other evidence in the case in determining whether or not the television set was defective.”
This instruction combines and substantially reproduces approved instructions set forth in CJI-CivM 14:24 and 14:25 (1984 Supp.). These instructions contain statutory rebut-table presumptions which were intended to apply to causes of action accruing on or after July 1, 1977. Colo.Sess. Laws 1977, ch. 199 at 820-21. See § 13-21-403(1), C.R.S. (1985 Cum.Supp.).
I.
Plaintiff contends, inter alia, that the giving of this instruction was error because the cause of action to which it was subro-gated accrued at the time of the fire, not when the proof of loss was executed. We agree.
A subrogee steps into the shoes of its subrogor and cannot therefore possess rights greater than those of its subro-gor.
See Employers Casualty Co. v. Wainwright,
Thus, it is generally held that statutes of limitation begin to run against a subrogee insurer at the time a claim accrues to its insured.
See, e.g., Indiana Lumberman’s Mutual Insurance Co. v. Curtis Mathes, Inc.,
II.
Defendant contends, however, that so instructing the jury was harmless error because plaintiff offered only circumstantial evidence that the TV caused the fire and, absent direct evidence of cause and defect, defendant was entitled to a directed verdict. We disagree.
To avoid a directed verdict in a strict liability case, a plaintiff must offer proof of each element set forth in
Restatement (Second) of Torts
§ 402A sufficient to create an issue of fact as to the existence thereof.
See Belle Bonfils Memorial Blood Bank v. Hansen,
Contrary to defendant’s contention, we are not here faced with an application of the doctrine of res ipsa loquitur: Plaintiff does not argue that the mere occurrence of the fire supports the inference *83 that the TV was defective. Indeed, plaintiff introduced evidence that, from the time Holtz unpacked the television from its factory carton, it was used normally and neither disturbed internally nor abused. Extensive and detailed testimony by experts in fire investigation showed that the fire started in the specific location of the TV and identified the area in the TV at which ignition occurred. This testimony also excluded other possible causes of the fire. All of this evidence was substantially un-controverted.
Defendant further contends that evidence showing that the TV ignited should not be sufficient to establish the inference that it was defective. However, direct proof of defect was impossible in this case because the TV was destroyed in the fire. A ruling that proof of defect is unattainable as a matter of law in circumstances such as these would effectively establish a conclusory presumption of non-liability in favor of strict product liability defendants whose products self-destruct in the process of causing injury to persons or property. We are not prepared to adopt such a view. Therefore, we hold that plaintiffs evidence was sufficient as a matter of law to create an issue of fact as to the element of defect.
See Liberty Mutual Insurance Co. v. Sears, Roebuck & Co.,
III.
Defendant next contends that the giving of this instruction was harmless error because the presumptions stated therein were merely redundant expressions of the state of the law prior to July 1,1977, and did not prejudicially affect plaintiff’s burden of persuasion. Again, we disagree.
To establish liability, a plaintiff must prove each element of its claim by a preponderance of the evidence.
See Exchange National Bank v. Sparkman,
We note that there is considerable dispute among courts and scholars regarding both the practical and the legal effects of instructing a jury as to its use of a presumption. Such instructions may mystify rather than clarify; this possibility may be exacerbated when, as here, a presumption is considered to be evidence in itself rather than a tool for reasoning. See generally McCormick on Evidence §§ 342-44 (3d ed. 1984); Allen, Presumptions in Civil Actions Reconsidered, 66 la. Law Rev. 843 at 855-59 (1981).
Prior to enactment of § 13-21-403, evidence of state of the art and regulatory compliance was only one of several factors to be considered in determining whether a product was defective.
See Blueflame Gas, Inc. v. Van Hoose,
Especially here, where the record reveals that defendant’s evidence of state of the art and regulatory compliance was unclear and confusing, we cannot say that the jury, in assessing whether plaintiff had met its burden of persuasion by a preponderance, was not influenced by the weighty proclamation that the law presumed the TV was non-defective. Consequently, we hold that the giving of this instruction was prejudicial error.
We do not reach the question whether defendant produced enough evidence of state of the art and regulatory compliance to entitle it to the instruction. Plaintiff’s argument that it was entitled to judgment notwithstanding the verdict is without merit.
Accordingly, the judgment is reversed and the cause is remanded for new trial.
