*1182 ORDER

HEATON, District Judge.
Plaintiff Douglas Brown,[1] the owner of a 2002 Chevrolet Silverado, filed a class action complaint against General Motors Corporation ("GM") premised on an alleged defect in certain car and truck engines it designed and manufactured.[2] In addition to claiming the defendant breached express and implied warranties and was unjustly enriched, and seeking injunctive and declaratory relief, the plaintiff alleges GM violated Florida's Deceptive and Unfair Trade Practices Act ("FDUTPA"). GM has moved to dismiss the complaint pursuant to Fed.R.Civ.P. 12(b)(6) and 9(b), contending it fails to state a claim and does not allege misrepresentation with the required particularity.[3]
When considering a 12(b)(6) motion, all well-pleaded factual allegations in the complaint are accepted as true and those allegations, and any reasonable inferences that might be drawn from them, are construed in the light most favorable to the nonmoving party. See Clark v. State Farm Mut. Auto. Ins. Co., 319 F.3d 1234, 1240 (10th Cir.2003). Dismissal is appropriate "`only when it appears that the plaintiff can prove no set of facts in support of the claims that would entitle the plaintiff to relief.'" Id. (quoting McDonald v. Kinder-Morgan, Inc., 287 F.3d 992, 997 (10th Cir.2002)). Reviewing the complaint under that lenient standard, the court concludes the defendant's motion should be granted as to the plaintiff's unjust enrichment claim and otherwise denied. The rationale for the court's decision follows a brief summary of the plaintiff's allegations.
In his complaint, the plaintiff asserts that certain engines, including that in his Silverado, that the defendant designed and manufactured for its 1999-2003 model year cars and trucks had a defect, referred to as piston slap, that resulted from excessive clearance between the pistons and the sides of the cylinder walls or bores. Piston slap, he alleges, causes a loud knocking noise, damages the engine, wastes fuel and oil, causes significantly higher vehicle emissions, reduces the vehicle's power and performance, and lowers the vehicle's resale value. The plaintiff alleges that when the engine in his vehicle began to make a loud knocking noise after start-up he took it to the dealership where he had purchased the vehicle. He was informed that the sound was "normal engine noise." The plaintiff contends that several Technical Service Bulletins GM issued in 2001 and 2003, not only demonstrate that GM was aware of the piston slap problem, but reveal the defendant's attempt to avoid liability and conceal the negligent design or manufacturing defect. He also alleges that as a result of complaints GM offers owners extended 6 year/100,000 mile warranties on the engines and engine parts, but then refused to cover piston slap under the new warranty.
Citing "no-injury" product defect cases, the defendant initially contends Brown cannot maintain an action under any of his legal theories for a defect that has not caused a compensable injury. This *1183 argument fails, however, as GM ignores the plaintiff's allegations, liberally construed, that the "defect had actually manifested itself in [his] vehicle[ ]," Briehl v. General Motors Corp., 172 F.3d 623, 627 (8th Cir.1999), and his allegations of injury, particularly his claim that piston slap harms the engine. The assertions of actual, present damage distinguish this case from those GM relies on, in which the plaintiffs "concede[d] they were not among the injured," Rivera v. Wyeth-Ayerst Labs., 283 F.3d 315, 320 (5th Cir.2002) or were essentially seeking to recover for a "potentially life-threatening defect." Lee v. General Motors Corp., 950 F.Supp. 170, 172 (S.D.Miss.1996).[4] It is true the amended complaint does not clearly and explicitly allege that the plaintiff's engine suffered from excessive piston-to-bore clearance or that his engine was damaged, used excessive oil or had sustained any of the other specific consequences alleged to stem from the "piston slap" defect. However, under the liberal pleading standard of Fed.R.Civ.P. 8(a), the court broadly interprets the plaintiff's complaint as making such allegations. In reaching that conclusion a further word about the terminology the plaintiff employs is warranted. The plaintiff has used the term "piston slap" in various ways, depending on the context. At times, the plaintiff is careful to identify the alleged underlying defect as excessive piston-to-bore clearance. He terms this defect "piston slap." At other times the plaintiff refers to "piston slap" as the noise resulting from the defect, a subtle but potentially important shift. As the defendant correctly notes, noise by itself is not a "defect" within the meaning of warranty claims, both contractual and pursuant to the Uniform Commercial Code or Magnuson-Moss Warranty Act, or under many states' consumer laws. E.g., Hasek v. DaimlerChrysler Corp., 319 Ill.App.3d 780, 253 Ill.Dec. 504, 745 N.E.2d 627 (2001); Miller v. DaimlerChrylser Motors Corp., 2001 WL 587496 (Ohio App. 8 Dist.2001).
To establish an actionable defect, the plaintiff must allege and ultimately prove not just that his vehicle was noisy, or that it generated what the plaintiff views as excessive noise, but that the vehicle in fact suffered from the underlying defect alleged  that the excessive piston-to-bore clearance resulted in engine damage, increased oil consumption and the like. For present purposes the question is whether the plaintiff has sufficiently pleaded the requisite defect. The court concludes he has. Dismissal of the complaint is not, therefore, warranted on the ground that the plaintiff has failed to allege a product defect or injury.
Breach of Warranty
GM contends the plaintiff's express warranty claim is deficient for lack of allegations that his vehicle exhibits or suffers from piston slap or that GM has refused to repair a defect in the engine or indicated an intent not to repair his engine under the warranty if premature failure occurs. Brown's implied warranty claim is undermined, GM argues, by his failure to allege that his vehicle's engine has failed in any way or is unfit for transportation. Neither argument is persuasive; the plaintiff has alleged sufficient facts to support both warranty claims.
Florida Deceptive and Unfair Trade Practices Act
GM contends that the plaintiff's claim under the Florida Deceptive and Unfair Trade Practices Act, Fla. Stat. Ann. §§ 501.201-213, 501.976, fails because he has not pleaded facts establishing he has *1184 sustained a loss as required by the statute. The court has previously addressed and rejected GM's contention that the complaint lacks allegations of injury. The plaintiff's state statutory claim will not, therefore, be dismissed on that basis.
As an additional ground for dismissal of the plaintiff's misrepresentation claim under the FDUTPA, GM argues that it is subject to the particularity requirement of Fed.R.Civ.P. 9(b) and the amended complaint's allegations are insufficient to meet the heightened pleading requirement. As a plaintiff does not have to prove the elements of fraud to prevail under the statute, Davis v. Powertel, Inc., 776 S.2d 971, 974 (Fla. 1st DCA 2001) (actual reliance on representation or omission not required), and "[t]he Florida Legislature intended [the FDUTPA] to be construed liberally," Cummings v. Warren Henry Motors, Inc., 648 S.2d 1230, 1233 (Fla. 4th DCA 1995), the court finds the plaintiff's FDUTPA claim satisfies the pleading standards of the Federal Rules. See id. at 1233.
Unjust Enrichment
Dismissal of the plaintiff's unjust enrichment claim is necessary, GM asserts, because Florida does not allow a party to recover under a quasi-contractual theory when a valid contract exists. The plaintiff fails to respond to GM's argument, asserting instead that he is entitled to plead inconsistent theories. Under Florida law an unjust enrichment claim fails upon a showing that an express contract exists. Williams v. Bear Stearns & Co., 725 So.2d 397, 400 (Fla. 5th DCA 1998). GM states in its brief that "the existence of an express warranty to repair any vehicle defect related to materials or workmanship occurring during the warranty period" is undisputed. GM's motion, p. 16. The complaint affirmatively alleges the existence of the warranty. The available contractual remedy precludes the plaintiff's unjust enrichment claim, which will be dismissed.
Accordingly, the defendant's motion is GRANTED as to the plaintiff's unjust enrichment claim and otherwise DENIED.
IT IS SO ORDERED.
NOTES
[1]  Brown was substituted as the named plaintiff for John Remor on January 20, 2005.
[2]  The plaintiff filed the complaint on behalf of himself and all others who purchased, from a GM authorized dealer within the State of Florida, any new 1999-2003 model year GM car or truck with a 3.1, 3.4, 4.8, 5.3, 5.7(LS1), 6.0 or 8.1 liter engine.
[3]  Although it pertains primarily to a different plaintiff, the court has not considered the extraneous information (plaintiff Massari's interrogatory answers) GM refers to in its reply brief.
[4]  At this procedural stage, the issue is whether the plaintiff has pleaded damages, not whether he can prove he actually sustained a cognizable loss.
