range Posted May 29, 2007 Share Posted May 29, 2007 Toyota chases Tundra camshaft failures Mark Rechtin Automotive News May 28, 2007 - 1:00 am LOS ANGELES -- A batch of camshaft failures in 5.7-liter V-8 engines has dinged the launch of the Toyota Tundra pickup. Camshafts in 20 engines have snapped, says Toyota spokesman Mike Michels. ...........Toyota rushed the 5.7-liter engine into production in time for the Tundra's February launch. The 5.7-liter initially was scheduled to arrive this summer. But Toyota dealers and product planners told the manufacturing arm that the Tundra needed the big V-8 at launch because the 4.7-liter V-8 would not make a strong enough statement. READ MORE ADDED 30 May 2007 - Tunda may be recalled Toyota Motor Corp. faces a costly setback in the biggest U.S. vehicle launch in its history after owners of its new Tundra pickup reported engine failures. The Japanese automaker may recall Tundras equipped with 5.7-liter V-8s to replace the engines, a company spokesman said Wednesday. The trouble with the Tundra's 5.7-liter engines, the most powerful engine available on the new pickup, is the latest in a series of recalls and problems that have dented Toyota's reputation.

Hydro Posted May 29, 2007 Share Posted May 29, 2007 (edited) The sad part is that this will fly right by Consumer Reports and other buyers references. They will stay "solid performer", "reliable", "It's a Toyota" status almost forgot to add.... Edited May 29, 2007 by Hydro Quote Link to comment Share on other sites More sharing options...
tim kakouris Posted May 29, 2007 Share Posted May 29, 2007 (edited) i'm not a subscriber, so i can't read the full article. but, it looks like it's a lot harder to design a class leading pickup than toyota thinks. it's not just about putting in bigger engines, bigger brakes, and stiffer springs.

range Posted May 29, 2007 Author Share Posted May 29, 2007 The media is already defending Toyota: The lead sentence of a story on Autoblog......."Out of a run of 30,000 5.7-liter V8 engines, Toyota has had reports of 20 camshafts snapping -- a minuscule number in light of the total (0.06 percent, as a matter of fact).

Catalepsy Posted May 29, 2007 Share Posted May 29, 2007 What do you expect? It is Autoblog. That site have the worst writing and writers. The mistakes they make (like not being able to tell the difference between a Jag XJ & S-Type or a Ferrari from Lambo) stop me from taking them seriously. Although they are a major automotive news source now, I have always wondered why someone else hasn't taken the idea of linking other people's stories and adding a paragraph of better writing to a new site.

Deanh Posted May 29, 2007 Share Posted May 29, 2007 what?!?!?! Toyota has been building shit trucks for a while now classic double standards...Ford has 6 or so Flame throwers which are a flash fix..the world has come to an end....Toyota beaks 20 camshafts which I am guessing requires a full engine teardown and the press gives a little sympathy.....conspiracy theorists unite!

Deanh Posted May 29, 2007 Share Posted May 29, 2007 maybe they should show the internals of the engine on youtube could be wrong but typical Jap engines are of the no fault design...i am TOTALLY speculating the internal damge may be pretty excessive....ESPECIALLY if it caused a belt failure as well...PLUS all that SOFT aluminum everywhere....engine replacemants perhaps?

RAdams Posted May 29, 2007 Share Posted May 29, 2007 I understand the hatred for Toyota but honestly -- 20 camshaft failures isn't a blip on the radar unless you're REALLY looking for it. I suspect this will have no effect on Toyota mainly for this reason, not because the mainstream media hates Ford & GM. Quote Link to comment Share on other sites More sharing options...

Doesn't the 5.7 using a timing CHAIN? As for the aluminum....most of the damage caused by a cam failure in any overhead cam engine would be limited mostly to the heads. What engine built today DOESN'T have aluminum heads? Either way, it's going to be a mess, but it wouldn't be any worse than a cam failure in any Ford engine.

TomServo92 Posted May 29, 2007 Share Posted May 29, 2007 I understand the hatred for Toyota but honestly -- 20 camshaft failures isn't a blip on the radar unless you're REALLY looking for it. I suspect this will have no effect on Toyota mainly for this reason, not because the mainstream media hates Ford & GM. But the rub is that they've only found 20 so far. The article quotes Toyota as saying they don't know yet how many of the 30,000 engines produced have this problem. Quote Link to comment Share on other sites More sharing options...
MKII Posted May 29, 2007 Share Posted May 29, 2007 I understand the hatred for Toyota but honestly -- 20 camshaft failures isn't a blip on the radar unless you're REALLY looking for it. I suspect this will have no effect on Toyota mainly for this reason, not because the mainstream media hates Ford & GM. Points from article "Camshafts in 20 engines have snapped, says Toyota spokesman Mike Michels. The outside camshaft supplier, which Toyota declined to identify, has traced the problem to "a metallurgical defect in the casting, a flaw in the metal which they have corrected," he says. To date, Toyota has built 30,000 of the engines, and the company is determining how many might be affected. Michels says that it was "an early batch," and that "Toyota is confident in the production from that point on." Toyota likely will not test each camshaft to see if it is prone to failure. Rather, customers whose camshafts fail will have their entire engines replaced." So Toyota knows the fault, Supplier to Toyota corrected the fault, Toyota knows how many engines have been built to date, but Toyota states they "likely will not test each camshaft to see if it is prone to failure." If they corrected said fault, they must know which engines, from the production date that have the correction made. Yes/No? Would a recall be in order in this situation, or at least a TSB, with letters to the owners of this vehicle equipped with the 5.7l V8.(early build batch of course) Or just let the new owners stress out with the knowledge that my engine might break down.
