*962 Opinion
Yamaha Motor Corporation, U.S.A. (Yamaha) appeals the trial court’s dismissal of its cross-complaint for equitable indemnity against Robert David Paseman and Carol Ann Paseman (the parents), whose adult son, David Paseman (David), is the plaintiff in the underlying action. Judgment of dismissal of Yamaha’s cross-complaint was rendered after the trial court sustained the parents’ demurrer without leave to amend.
In the underlying action, David is suing Yamaha for injuries he sustained while riding a seven-year-old moped owned by his parents. The complaint alleges the moped was defective and Yamaha is liable on the grounds of strict product liability, general negligence in design and manufacture of the moped and failure to warn. Yamaha’s cross-complaint for equitable indemnity alleges the parents negligently failed to maintain and repair the moped, thus contributing to or solely causing the injury to David.
Yamaha contends comparative fault principles may be applied to apportion fault between a strictly liable defendant and a negligent defendant and, therefore, it should be allowed to seek indemnity from the parents in proportion to their contribution to David’s injury. We agree and reverse the judgment of dismissal after the order sustaining the demurrer without leave to amend.
Factual and Procedural Background
The pleadings set forth the following operative facts: On November 25, 1985, David was injured while riding a seven-year-old Yamaha moped purchased and owned by his parents. His complaint, filed about a year later, alleges the pedals of the moped spontaneously engaged, causing David to lose control of the vehicle and incur injuries. Various theories are set forth against Yamaha in the complaint: Strict products liability, general negligence, breach of warranty and negligent failure to warn.
On January 24, 1989, Yamaha filed a cross-complaint against the parents. This cross-complaint, the subject of this appeal, alleges two causes of action: Indemnity and negligent failure to maintain and repair. 1 In particular, Yamaha alleges the moped in question was not *963 defective. Alternatively, if the moped is found to have been defective, Yamaha pleads the parents knew or had reason to know of the defect and necessity for maintenance or repair prior to David’s accident, but failed to properly maintain and repair the moped or to warn David of its defective condition. 2 For these reasons, Yamaha seeks equitable indemnification from the parents in the event any judgment is rendered against Yamaha in the underlying action.
The parents generally demurred to Yamaha’s cross-complaint claiming failure to state a cause of action. (Code Civ. Proc., § 430.10, subd. (e).) Their demurrer was sustained without leave to amend and the trial court rendered judgment of dismissal of the cross-complaint. Yamaha timely appeals the judgment.
Discussion
To begin, we recite our standard of review as set forth by this court in
Lewis
v.
Purvin
(1989)
In light of these rules, the issue before this court is whether Yamaha has alleged facts in its cross-complaint entitling it to relief on any legal basis. Resolution of its claims requires analysis of the duties owed by the parents *964 to their son and of the equities involved in applying indemnity doctrines to these facts. 3
I
Duty of Parents
In assessing the validity of Yamaha’s cross-complaint, we start with two basic premises. First, as stated in
Munoz
v.
Davis
(1983)
The parties have addressed the issue of the requisite joint and several liability by inquiring whether there was any concurrent causation of David’s injuries due to the separate acts of Yamaha and the parents. We agree this is a necessary approach to the issue presented. As a threshold matter, we add that before this causation question may be reached, a determination must be made as to the existence of a duty on the part of the parents that was arguably breached, for without such a duty, there can be no causation.
Generally, determination of the existence of a duty is a question of law for resolution by the court.
(Lopez
v.
McDonald’s Corp.
(1987)
In examining the pleadings, our inquiry is whether they fairly raise the issue of whether these parents owed a duty of care to third party users of their property (the moped) to maintain the product in a safe condition and *965 to warn any users of defects in the property if they had or should have had such knowledge. If so, breach of that duty could arguably lead to concurrent or successive causation of injury, thus giving rise to a right to indemnity. Here, Yamaha has pled in its cross-complaint its product was not defective, but if there were a defect and Yamaha is held liable, the parents should be held jointly and severally liable. Yamaha has therefore raised the issue of whether David’s injuries were caused by its manufacturing defect or instead solely or partially by the parents’ alleged negligent maintenance.
We rely on basic rules applicable to owners of motor vehicles to determine whether a duty exists on the part of the parents that is separate from Yamaha’s duty to make a defect-free product; existence of such an independent duty of the vehicle owners may validate the application of concurrent causation theory here. We begin with the general duty of care imposed by Civil Code section 1714, subdivision (a), applicable to owners of motor vehicles: “Everyone is responsible, not only for the result of his willful acts, but also for an injury occasioned to another by his want of ordinary care or skill in the management of his property . . . .”
An owner or operator of a motor vehicle has both a statutory and common law duty to use reasonable and ordinary care, by properly maintaining the motor vehicle, to prevent an increase in the chances of inflicting injury on others by use of the vehicle.
(Twohig
v.
Briner
(1985)
Additionally, this duty of care encompasses the duty to reasonably inspect the motor vehicle for defects.
(Sherman
v.
Frank, supra,
These basic authorities convince us that, as a matter of law, the facts in the pleadings fairly, though incompletely, pose the issue of whether the parents were under an independent duty of care to adequately maintain their moped, inspect it for defects and warn any user, including David, of a defective condition prior to permitting use of the moped. The nature of any such defect has not yet been resolved. For example, if an operational defect
*966
developed after manufacture, the parents may have had knowledge of that. Possibly, too, even if a manufacturing defect existed, it could have been worsened by lack of maintenance. All these issues, as well as a determination of whether any duty on the part of the parents was breached and whether such a breach was a proximate cause of David’s injury, are factual issues not yet before any court at this pleadings stage of the proceeding. We restrict our review of the correctness of this ruling on demurrer to a consideration of whether Yamaha has stated sufficient facts showing it may be entitled to relief under any theory.
(Lewis
v.
Purvin, supra,
We next address the issue of the equities of applying indemnity doctrines to these facts.
II
Application of the Comparative Indemnity Doctrine
Having found the existence of a specific duty of care on the part of the parents toward David, we turn to the implications of such a finding upon the operation of the doctrine of indemnity. The general rule regarding the applicability of this theory is set forth in
Jaffe
v.
Huxley Architecture
(1988)
Further, as this court held in
Woodward-Gizienski & Associates
v.
Geo-technical Exploration, Inc.
(1989)
Here, Yamaha contends the alleged negligence of the parents was a contributing or sole cause of David’s injury and, therefore, under comparative fault principles, it must be allowed to seek indemnity from the parents by way of cross-complaint. The doctrine supporting such a comparative equitable indemnity claim originated in
American Motorcycle Assn.
v.
Supe
*967
rior Court
(1978)
This doctrine was later expanded to include not only apportionment of fault between concurrent negligent tortfeasors, but also apportionment of loss between a strictly liable defendant and a negligent plaintiff.
(Daly
v.
General Motors Corp.
(1978)
In
Safeway, supra,
Thus, the court found Safeway liable for its conduct in negligently failing to maintain its carts and did not confine its holding simply to a theory that Safeway incurred joint and several liability because it was a link in the chain of distribution to consumers of the defective product. Instead, Safeway’s own negligence in maintaining its carts was determined to be a contributing or superseding cause of the plaintiff’s injury.
In
Southern Cal. Edison Co.
v.
Harnischfeger Corp.
(1981)
*968
The issue of concurrent or superseding causation in this context was also touched upon in the case of
Vermeulen
v.
Superior Court
(1988)
Here, two separate duties were owed to David. Yamaha, as the product manufacturer and distributor, was under a duty to provide a moped free of manufacturing defects. The parents, as consumers and owners, were under an independent duty to maintain the product in a safe condition, as well as to warn David of its defective condition if they had such knowledge or reasonably should have had such knowledge.
(Twohig
v.
Briner, supra,
Additionally, as stated in GEM: “. . . a defendant/indemnitee may in an action for indemnity seek apportionment of the loss on any theory that was available to the plaintiff upon which the plaintiff would have been successful.”
(GEM Developers
v.
Hallcraft Homes of San Diego, Inc., supra,
Notwithstanding these rules, the parents argue there is no equitable basis for indemnity principles to apply. They assert they are not joint tortfeasors with Yamaha because they did not take part in the design, manufacture or distribution of the moped. Accordingly, they claim they had no effect upon any potential liability of Yamaha grounded in strict products liability or negligence, and thus may not be held jointly and severally liable. However, they are confusing “joint and several liability” in the present context, as it *969 applies to concurrent tortfeasors, with “joint and several liability” in the vicarious liability context.
In
American Motorcycle Assn., supra,
Moreover, in
GEM, supra,
This specific authority controls over the more general rule of
Munoz
v.
Davis, supra,
Other unusual and unsuccessful attempts to invoke the claim of indemnity are also distinguishable. In
Woodward, supra,
Likewise, this court determined the doctrine of equitable indemnity should not apply in
Jaffe, supra,
Here, however, unlike the situations in
Woodward, supra,
Based on all the circumstances alleged in these pleadings, policy reasons additionally support the application of the comparative equitable indemnity doctrine to this case. We do not think equity would be served by precluding a distributor or manufacturer of a product, especially a seven-year-old motorized vehicle, from bringing an action for comparative equitable indemnity against a consumer who allegedly failed to maintain the product in a safe condition or to warn its innocent users of its defective condition. We have already established that consumers are under a duty to maintain property in a safe operating condition. No exemption from this duty should be allowed on the grounds the manufacturer/distributor originally produced a defective product, particularly after a lapse of time (here, seven years) since purchase of the product. Holding to the contrary might create an incentive to consumers to be negligent in their maintenance of their property. Allowing apportionment of fault between an allegedly strictly liable manufacturer/distributor and an allegedly negligent consumer/owner would not relieve the manufacturer/distributor of its duty to produce defect-free products, since it could still be held liable under a theory of strict product liability. However, in appropriate cases, equity requires that a manufacturer/distributor be permitted to seek equitable indemnity from an allegedly negligent concurrent or successive tortfeasor, even if that person is a consumer/owner, by pleading failure to maintain the product in a safe operational condition.
Here, Yamaha should be entitled to seek to have the loss spread on a broader base. As recognized by the Supreme Court in
Safeway Stores, Inc.
v.
Nest-Kart, supra,
Under a fairness analysis of these facts, Yamaha must be allowed to bring a cross-action seeking comparative equitable indemnity from the parents by alleging and proving, if it can, the parents’ negligence either contributed to or solely caused David’s injury. However, on the current state of the pleadings, the independent duty of the parents to provide a safely maintained and operational vehicle to David is inadequately alleged. Clear assertions of such an independent duty are required to fully present the issue of concurrent causation to the trial court. Where it appears a pleading is capable of being improved by amendment, a trial court abuses its discretion
*972
by failing to permit an opportunity to amend.
(Lewis
v.
Purvin, supra,
Disposition
The judgment of dismissal is reversed with directions to permit Yamaha the opportunity to amend its cross-complaint in accordance with the views expressed in this opinion.
Benke, Acting P. J., and Nares, J., concurred.
Notes
Specifically, the cross-complaint alleges Yamaha is entitled to indemnity and contribution from the parents under the doctrines of full equitable indemnity, total equitable indemnity, equitable indemnity and implied contractual indemnity. The Supreme Court in
Far West Financial Corp. v. D&S Co.
(1988)
With regard to the theory of implied contractual indemnity, our reversal with directions to allow amendment of the cross-complaint gives Yamaha the opportunity to pursue that claim if there are facts to support it.
Yamaha, in its opening brief, refers to specific facts not set forth in the pleadings regarding the parents’ maintenance of the moped. We may not consider these extraneous facts on appeal of this ruling on demurrer.
(Colm
v.
Francis
(1916)
We also decline to take judicial notice of previous writ proceedings in this court, Yamaha Motor Company, U.S.A. v. Superior Court (June 14, 1989) D010207 [nonpublished opinion], as requested by the parents. We have examined that record and find it to be of no conceivable relevance to the issues in this case. (Evid. Code, §§ 452, subd. (d)(1), 459 subd. (a).)
We note Yamaha has also asked this court to stay the trial of the underlying action in the event this appeal is not resolved by April 29, 1991. Apparently Yamaha lacks faith in the efficient conduct of the business of this court. Due to the timeliness of resolution of this appeal, the request for stay is moot.
