Attorneys working with ClassAction.org are investigating whether the camshaft seals in these vehicles are defective and whether a class action lawsuit can be filed to help drivers get back the money they have – or will – spend on repairs.
As part of their investigation, the attorneys need to hear from drivers who experienced cam tower leaks, overheating or other symptoms of camshaft failure to learn more about the problem and to determine whether a defect is to blame.
What Could Be Causing the Camshaft Seal Leak?
Attorneys working with ClassAction.org are looking into whether the camshaft seal is causing problems because of its design. It is believed that the seal on the camshaft is a machine-applied seal – as opposed to a gasket – and that its material can wear out earlier than expected.
What Are the Symptoms of a Bad Camshaft Seal?
Symptoms of camshaft seal failure can include:
- Oil leaks from the cam towers
- Smell of burning oil
- Overheating
- Vehicle stalling
- Vehicle backfiring
- Smoke from the exhaust
- Rough-running engine
- Engine fire
Drivers Complain of Cam Tower Leaks, Seepage
Several drivers, particularly Toyota Tundra drivers, have posted complaints online regarding cam tower leaks in their vehicles. A sample of these complaints can be found below [sic throughout, emphasis ours]:
I have the annoying cam tower leak for a 2nd time. I have a 2011 Tundra with the 4.6. I purchased the Tundra in 2017 from Carmax and thankfully purchased the extended warranty of 5 years or 25,000 miles. I figured it was a Toyota and didn't think I would need more than that-in fact I had originally planned on cancelling the warranty but forgot to in 30 days. I am very thankful that I forgot because this truck will now have had around $9K worth of repairs done on it since I purchased it.”

First Tundra (2006) I owned had 200k on it only brakes, oil and tires. This Tundra 2016 72k and a cam tower leak. If I wanted headaches I would of bought a Ford. Expected better out of Toyota.”

Just got back from the second dealership and they diagnosed it as a passenger side tower cam leak starting...It’s not bad enough yet to justify cracking the engine open but did say it will be ready by 20-30k all warranty. Nice....at only 8400 miles, come on Toyota!!”

I dropped my 2011 Land Cruiser off today and have been told that my front cover is leaking badly and one of the cam boxes is seeping. After some research, this is becoming a fairly common issue, especially after visiting the Tundra forum!”

What Could I Get from a Class Action Lawsuit?
If a class action is filed and successful, Toyota and Lexus drivers could recover money for repair costs and loss of vehicle value because of the camshaft issue. A successful case could also force Toyota and Lexus to extend drivers’ warranties, find a fix for the problem or otherwise offer a remedy to owners and lessees.
