I own a 1999 Sienna and it has had brake failure in light snow several times. More recently, the brakes made a grinding sound and did not stop the van in a reasonable amount of time when going through bits of packed snow on an otherwise clear street.

Brake failure is a serious issue. There have been accidents associated with brake failures in Toyota's. What is the ABS doing? Or, more importantly, what is it NOT doing to stop the vehicle?

Is Toyota going to repeat the "driver's don't know how to properly use their ABS" that Chrysler did a few years back? Seriously, when will Toyota wake up to this problem? It is NOT an owner problem; it is a system problem... a system that should NOT need replacing over the lifetime of the vehicle!

Let me guess... will Toyota take the approach using the "owners aren't properly maintaining their ABS" refrain that it tried in the sludge matter? If it does, it doesn't learn from its own mistakes, does it?

No, Toyota has some major SAFETY issues to address in late-model Toyota's. I hope it knows that many owners are watching what it does in each case. A company of its size shouldn't underestimate the collective power of its customers. The customers who haven't had a fair shake are still joining forces. Just check the "Toyota Owners Unite for Resolution: Engine Oil Sludge" customer base if you don't think they are! Believe you me, there are still a lot of very concerned Toyota owners out there. Try talking to the ones who have had major ENGINE FIRES to see what they think about Toyota SAFETY! How many have lost their lives? We do know quite a few have almost lost their lives in a BLAZING TOYOTA!

Thank you for this forum. The Toyota owners need to share their information. Toyota needs to take note, too.

I beg to differ with the second person on this, but the 1ZZ does in fact fail in fairly short order: Engine consumes a little bit of oil, destroys pre-cats with contamination, the cats fall apart and end up in the main cat, which causes an increase in back-pressure, which causes the rings to fail even faster, which increases cat degradation, etc.

Just go onto spyderchat.com and look under Care and Maintenance, look at the 'engine replacement log' at the top, and see just how many 1ZZ's have failed in just the Spyders alone (a low volume car).

My own car ate about a half quart of oil in the 80,000's, 1 qt every thousand miles at 91,000 miles, and at 99,000 miles, is eating two quarts of oil every 1000 miles.

It's well documented, very common, since-fixed, but a definite problem for 2002 and back Toyotas equipped with this engine.

Additionally, in my particular case, I'm covered by Toyota Extra Care, which covers the entire powertrain, and even with my dealer-done oil changes every 3000 miles, I'm still having to fight with everyone to get the engine handled. I've done more maintenance than required, always checked my oil, and oh yeah, I've worked for Toyota for 13 years, and it's been a royal hassle trying to get this taken care of.

The car has never been raced, has no aftermarket parts of any kind, and is within the warranty time frame. I've since started cases with the Federal Trade Commission, the Insurance Commission of California, and the Attorney General.

Hey, I'm not getting taken care of, so what am I supposed to do? Roll over and die? Pay $5000 for an engine that everyone admits is failing, but no one is willing to fix? Huh?

Well there ya go, that's what happens when you drive the crap out of the car and expect it to keep going.

In your next car, change to oil and keep it topped up with coolant.

Simple as.
