Electric Power Assisted Steering does not use a pump. But thanks for playing.
To be sure, there are, or have been, hydraulic steering systems that had the hydraulic pressure supplied by an electric motor, but the electric steering they use on the Corolla doesn't have this kind of system.
I'd not go so far as to say what they are using is an unproven technology, it's been around in one or more of it's various forms since about 1965. The current implementation used by Toyota looks like the Acura NSX of the early '90s, and the BMW system of the early 2000s. .
Yes, it could be a similar feeling on all vehicles that employ it. And not all issues 'reported' by the medi...er, that is, actual Toyota owners my just be their unfamiliarity with their cars. Owner's Manuals are wonderful.
_______________________ Wow - a fastback 'rolly! Notice I didn't say "hatchback". That actually holds its own against anything after 2003 as far as looks goes! Whatever happened to those days, man?
Well, nice to know you have ps similar to what I described above. There are two main categories of power steering - regardless of form(electric or hydro): fixed and variable. Manufacturers, particularly GM, were notorious for using a waaayyy overboosted fixed setting on most platforms, making even a 20ft Bonnie or DeVille a snap to park - but impossible to maneuver through turns or curves.
Now why did they do that, Hachi? So LAZY AMERICANS who want everything EASY didn't have trouble parking the damn things!! "Handling"? Duhhh..whut's that? LOL
Next is variable ps, which uses bleed-back or speed-related sensors to gradually reduce the ps assist as veh. speed increased. But that costs $$$, right? Which is where I come in:
If variable PS is so expensive and/or difficult to manufacture for the masses(those folks who don't drive expensive German sedans), then I for one would gladly settle for a car that is *a bit* of a beast to park, but tight and stable at any speed over 10mph. That is, a fixed pressure PS system at a lower than usual pressure.
I know this is probably in the works, but I think a dashboard push- button solution might help - have three settings for steering assist: Max, Normal/Var., and "Sport"(which addresses the desires in my last paragraph). This is something where an Electric PS might really shine
- since it's all electric, have an electronic user interface so different drivers can select the amount of road feedback and steering feel they desire simply by selecting one of several settings. Build in a brake-pedal sensor so a selection canNOT be made unless a foot is on the brake.
I've an 02 Nissan Almera with Hydraulic power steering and an 09 Toyota Auris SR180 with electric power steering. They both handle exactly the same to me.
If you can turn the wheel at all from straight without the front wheels moving the your vehicle is using "Recirculating Ball", this system normally leaves a dead zone in the middle, but some car makers like it as it makes the steering geometry simpler, especially when setting up Ackermanns principle. Here in the UK, only Rack and Pinion is used, as it's the only steering system precise enough (no play) to get through the MOT.
That's quite an interesting idea. I'd patent it...NOW!
The variable assist in the Toyotas senses engine revs and cranks up the juice for low speed use, and then scales back at higher speeds. When I first heard of it (Power steering? UGH! My first two cars were so light is wasn't necessary!) but the sytme works well, from the Corolla to the Supra and even the Tercel.
We went to buy a 'stripper' Corolla in 1987, $7,500. No power steering AT ALL. After trying to just take a corner at low speed I brought it back and said, "Show me that loaded one!"

Over here, The order of the day in reliability used to be, Lexus Honda, Toyota, Nissan, Mazda. Now Nissan is way down with just average for it's reliability, about 25 down the list. The only thing I can think is that different counties or even factories have different standards.

As the AP article clearly states--numerous times--these are ALLEGED to have involved mechanical malfunction.
Since 2000, not ONE of those 34 deaths has been PROVEN by the NHTSA to have been the result of ANY kind of mechanical malfunction.
People die in road accidents in the US approximately 40,000 times per year, the vast bulk of those being caused by simple human error. Those 34 deaths are unlikely to be any different from the other 40,000.

The very first time I had guacamole, it was at a fast food restaurant and it was awful. I decided guacamole HAD to taste better than that, so I dared to try it again, but at a different establishment, and it was excellent. Now I love guacamole and can tell the difference between bad guacamole and good guacamole.
I'm glad I kept an open mind about the subject.
I think you're being overly dramatic about this.
EPS is identical to hydraulic PS in that the steering linkage is identical between the two. Either way, you have a solid mechanical connection between steering wheel and road wheels.
It is NOT possible for EPS to just "veer off" without movement of the steering wheel.
Thirty four is the (unsubstantiated) number being reported by the media, most notablt NBC, which seems to have a hair across it's ass for Toyotas. At least Brian Williams does.
Yup. I have had 12 Toyotas. No more than the usual problems any car has, and most actually better than average, and a couple much better than average. The oldest car I have is almost completely original except for brakes and exhaust. The one before that was even better. I have had very few problems, and the few I have had were often taken care of by Toyota, in one case even after the warranty had expired. And I don't baby them either. I drive the wheels off of them, often near the envelope of specified performance. But I also don't expect a lot of them more than the solid, dependable transportation they're known for. GM and Ford have had far, far more transgressions then Toyota, and often as a result of design flaws and not faulty parts. So far nothing Toyota has issued the recalls for are an issue of design, but more the onus lies with the parts suppliers.
And the other side of the coin is that Toyota is NOT GM or Ford. The family takes pride in the product they offer, and have now lost 'face' due to the recalls. I fully expect it not to happen again for a long long time. Rather than move on to the next mistake like GM would do, I'd bet my last dollar the family, which has again become involved with the day to day operation of Toyota, will go out of their way to make sure more errors like this do not occur. I'm betting the temporary shutdown of the US plants is in part to have the employees go over ALL the parts in inventory and make sure they are up to spec so nothing like this happens again. And you can bet CTS's and Dana's parts are going to be inspected and tested
100% or damn near close to make sure Toyota doesn't end up with egg on it's face again.
Toyota is going to take a hit on the marketplace for all this negative publicity, and I think that's great, because I'm going to get my next excellent car from them at the pricing I expect from Toyota. One of the reasons I bought them all these years is because of the excellent value they have provided me.
And if none of the things I've said above happen, I'm going to turn my back on them just the same as I have GM.
