Mazdaspeed 3 vvt noiseOn 28.03.2021 by Shakinos
February 22, — A Mazda VVT variable valve timing lawsuit has been dismissed after a federal judge threw out most of the claims against the automaker. Lead plaintiff James Stevenson says his CX-7 experienced engine failure in related to the VVT assembly when the car had 63, miles.
Stevenson filed the VVT assembly lawsuit in August alleging he bought the Mazda CX-7 in Augustnot knowing the engine had an alleged defect. The car was sold with two warranties: a new vehicle limited warranty of 36 months or 36, miles and a powertrain limited warranty of 60 months or 60, miles.
The CX-7 has a VVT-equipped engine that according to the lawsuit, has defects that cause the timing chain to loosen or detach. The plaintiff claims Mazda knew about the VVT problem as early as because the automaker sent a technical service bulletin TSB to dealers in November According to the TSB, "[w]hen the engine is started, some vehicles may exhibit a loud ticking noise from the variable timing actuator at first start for a couple of seconds.
This is caused by the lock pin of the variable valve timing actuator not fully engaging. The November TSB was then superseded by another bulletin dated January 16,authorizing dealers to replace additional parts related to the VVT assembly and permitting new repair procedures.
According to the lawsuit, from there it was a TSB festival as the VVT bulletin was updated at least seven times through Februarywith each new TSB expanding the models and years of production. The plaintiff says Mazda failed to warn owners of the VVT problems and instead, allegedly "restricted dissemination of this knowledge to its authorized dealer service departments.
The letter informs owners that "a loud ticking noise may be exhibited from the VVT when the engine is first started at cold condition. However, there are conditions that apply to be eligible for the warranty extension.
First, the extension excludes vehicles made in certain years and second, the warranty extension "does not apply if the problem is caused by poor vehicle maintenance. In its motion to dismissMazda successfully argued it wasn't aware of the VVT problems when the plaintiff purchased the CX The plaintiff claimed the automaker must have known about the VVT engine problems because the National Highway Traffic Safety Administration had received five complaints about the subject.
However, the judge agreed five complaints out of all the allegedly affected Mazda vehicles weren't proof the automaker knew of problems. The automaker also said its motion should be granted because the plaintiff admits his CX-7 started having problems over 3, miles beyond the end of the warranty. Mazda argued claims of consumer fraud, breach of implied warranty and concealment should all be dismissed because the plaintiff failed to allege facts to satisfy the pleading requirements to establish any of the claims.
District Judge Freda L. Wolfson granted Mazda's motion to dismiss by tossing out most of the claims. The judge completely dismissed three claims and partially dismissed the warranty claims. According to the judge. That left the only recourse the extended warranty angle, something that might have been a tough sell.
Once the judge had tossed the claims other than claims concerning the extended warranty, both parties agreed to voluntarily end the Mazda VVT lawsuit. Mazda Motor of America Inc.

They are an integral part of internal combustion which can be broke down into 4 key phases:. Both need to be opened and closed with precision, hundreds of thousands of times. Early on, valves opened and closed for a specific amount of time only. That is wasteful and advances in engine technology now allow the timing, lifting, and duration that valves are left open to all be tweaked.
Automakers all use a variety of VVT systems, but they all come with one thing — complexity. Left untreated these problems can lead to oil leaks, stretched out timing chains, and catastrophic engine failure.

Thread starter RichB Start date Sep 12, After my engine is warmed up and I am sitting at idle, it sounds like I have a rattle noise coming from the passenger side of the engine. I hear nothing when the engine is cold. Could it be my timing chain? When should the timing chain and tensioner be changed?
What about the VVT? Any insight would be greatly appreciated. Darth Vader. Betting on the accessory belt tensioner. Remove the accessory drive belt and start the car. Still there? Then look elsewhere. VVT should typically be a rattle at startup that goes away as oil pressure builds. Put your finger in the oil fill and push on the timing chain between the chainwheels. Should be no slack here.
I thought the noise was my accessory belt tensioner at first but I replaced it over the weekend and I still hear a rattle. I opened up the oil cap to check the chain and I can basically lift if off of the sprocket. I am guessing that I have too much slack. I had my tensioner go bad. Now after 10k more it sounds to be going again.Mazda faces a class action lawsuit brought on behalf of vehicle owners, alleging that the automaker intentionally concealed information about an engine valve defect and has refused to repair the problem.
The complaint PDF was filed in the U. District Court for the District of New Jersey on August 21, seeking class action status to represent all owners of Mazda vehicles that used engines equipped with a variable valve timing VVT assembly.
Unfortunately, as part of the purchase process, Mazda has concealed material facts regarding the defect from purchasers and lessors of vehicles equipped with a defective VVT assembly. None of the defective engines have been in production sinceaccording to the complaint.
However, class action indicates that the company has known about the problem since Novemberwhen it issued a technical service bulletin TSB to dealers stating:. When the engine is started, some vehicles may exhibit a loud ticking noise from the variable valve timing actuator at first start for a couple of seconds.
This is caused by the lock pin of the variable valve timing actuator not fully engaging.
What Owners Are Saying
Heat treatment has now been added around the hole of the variable valve timing rotor lock pin to prevent this from happening. The lawsuit says that the company determined that the variable valve timing assembly problems were caused by inadequate or improper hardening of the components when they were first manufactured and attempted several times to fix the problem.
The company has also received a number of consumer complaints about variable valve timing assembly failure leading to catastrophic engine failures, according to the complaint. However, the lawsuit claims that Mazda referred to the problem as a noise concern and did not advise consumers that it could lead to catastrophic engine failure, and excluded a number of vehicles with the defective VVT from the program.
The class action lawsuit for Mazda vehicle owners indicates presents claims for fraudulent concealment, breach of warranty, and violating consumer protection laws.
This is BS and Mazda needs to step up and honor this poorly designed engine. How many people need to experience the same exact issue for them to accept a class action suit?

Skid Plate but who has one of those?
