Potentially life threatening! Alternator failed resulting in very heavy steering...

DJ WIPEOUT

Hi all,

2005 Toyota Avensis, 127 thousand kms travelled

Granted the car is 'old' at 14 years, however, with a low distance travelled relatively speaking!

Regardless of the debate around it's age and warranties etc, I would like to know others thoughts on how an alternator failing could not be considered to potentially life threatening by an authorised dealer when it results in very heavy steering!

I was driving to work (normally I cycle hence the low kms) one day and all of a sudden the car's steering became very heavy at a set of lights while waiting to take a turn at a junction. There were no warning lights nor any effect to the electrics as they were all still on.

I pulled the steering wheel with force over to the left in order to veer the car over to the side of the road. When I turned the car off the electrics would no longer work and the steering remained very heavy.

Authorised dealer has said car is fine now that the alternator has been replaced with a reconditioned one.

My problem is I don't feel comfortable driving the car on the M50 at 100-120kms if the steering goes again due to electrical failure...

Is this a manufacturing defect?

wonski

Steering was there, but you lost power steering.

It isn't a real safety issue, more like inconvenience.

Also the higher the speed the less heavy the steering would become. Its only at low speed that you would feel it heavy.

Car is fixed, unlikely to happen anytime soon with reconditioned unit.

Del2005

The car will still steer perfectly fine you just need to use more muscles, before power assisted steering became ubiquitous this is what people had to do. The faster you are travelling the less you'll notice the lack of assistance.

James Forde

Same thing has happened to me on 3 occasions now with my Focus.

Keep an eye out for warning signs on the dash as it will usually give you and indication if the alternator is about to die. Abs light/Handbrake light come on, all dials stop working etc.

Scary when it happens the first time mind you.

Midnight_EG

You should definitely try Toyota for a warranty claim on this, and keep us in the loop...they might not charge you

theteal

Is an alternator that dies after 14 years of use a manufacturing defect?

Tacitus Kilgore

Frightening more so than life threatening, car can still steer perfectly, just requires a little more effort while moving, and a lot more effort if the car is stationary.

Alanstrainor

Alternators are not for life. The dealer identified the fault, fixed it so really you should be good for years to come. You can worry all you like, but I can't see why it would fail again any time soon. And honestly the car would be much easier to steer at speed anyway, the greater the speed the easier it is to steer. It seems to have failed when you were stopped, which would take quite some force to turn the wheel.

Anyway, it was an annoying situation but nothing to worry about. And here's a top tip forget going to the dealer with a 14 year old car, find a good independent local to you and save a fortune.

Tacklebox

Happened to me on an old golf it was scary enough, as I was actually slowed down coming into a roundabout.

seamus

Hah, the things we take for granted.

It's my recollection though that steering wheels before power steering used to be bigger, this would make it easier to turn them.

Am I right, or is that in my head? If it is the case, then it would definitely make the loss of power steering even worse.

my3cents

I don't really see how this happened?

I assume the OP's car stalled or something and wasn't running when the steering went heavy?

And what about the brakes? They normally need much more pressure to operate when the engine is off.

Edit> This answers my question third post down https://www.toyotaownersclub.com/forums/topic/141587-avensis-05-power-steering-issue/

DJ WIPEOUT

Thanks Wonski, well put! It just didn't feel safe at the time when trying to move from a stationary position at lights (waiting to turn right) to cut across the lane running alongside me (going straight) into thankfully some car parking free space at the side. I didn't want to even imagine would it would be like at speed but I guess from all the responses so far that it would have been fine!

pablo128

Petrol Avensis of that era has electric power assisted steering. No electricity means no power assistance. The car is fixed. Drive on.

TheBoyConor

More like a fail-deadly design flaw than a manufacturing defect if the car's electrical system is designed in such a way that a failure of the alternator would have a knock on effect of knocking out the power assist steering.

Just thinking about this at a basic level, even if the alternator failed suddenly the car still should have an ample reserve of electrical power in the battery to be able to run the power steering. The fact that the rest of the electrical items still worked would indicate that there was ample electrical supply left.

Thinking again, it may be that the signal from the spinning alternator enables the steering assist motor at a software level. If this wasn't the case the power steering would function with the engine off but the ignition switched on which you wouldn't want. A failure in the alternator may mean that this signal was lost and the control system then "thought" that there was no signal from the alternator, therefore the engine is off, so don't activate the power steering.

I may be wrong here in this case, but I do know that some vehicles do use the AC signal from the alternator to determine that the engine running.

If this is the case here it is a fail deadly design as it could result in the situation you describe.

Of course this may not be the case at all as I do not know the ins and outs of these cars.

Toyotafanboi

Not a snowballs chance in hell of goodwill IMO. If you aren't comfortable any more in that car, you're only alternative is to sell it and buy another and take effectively the same chance again.

Sure any failure in a car is life threatening in the wrong circumstance, that's the chance you take using one really. Engine failure could have caused the same issue. If you were to draw up a list of things that could fail in a car unexpectedly that could kill you, it'd be a super long list.

I know the electronic steering in those is very heavy when you loose power, not like hydraulic steering where when you loose power you can still manhandle it, electronic steering is almost effectively locked. No doubt you may have gotten a fright.

It's not really a manufacturing defect in the strictest sense, it's more like aging/ wear in this scenario. If the alternator didn't last 12/ 24/36 months, you could argue it was a manufacturing defect as you easily expect an alternator to last that long and while most of us expect an alternator to be a life long item, the reality is a failure after 168 months/ 14 years is very difficult to define as a manufacturing process related defect as opposed to any kind of excessive wear, incorrect maintenance or external influence it may have been exposed to since then.

This is pretty standard. The alternator is a crucial part of the electrical system when the engine is running. If it dies, anything dependent on electrics will fail, including power steering.

Better that some steering is available, than none at all.

Hydraulic power steering is not electrics-dependent, but equally can fail suddenly, and the driver will have the exact same experience.

Wasn't there a recall on some of those? See the link I posted above but that seems to have been for the steering shaft whatever that is?

Toyotafanboi

Not that I'm aware of.

The reality is, the alternator failed so actually the whole car stopped working, just the only symptom that the OP has honed in on is the (obvious) loss of steering. There actually is nor was anything wrong with the OP's steering, that we know of anyway. An electrical fault shut the whole car down, including the steering.

......

How could that be?

Sure even if the alternator imploded or fell clean out of the car havent you still got a battery with a reserve of power to run the car's systems for a time? Hence the presence of a alternator light on the dash to let you know the alternator is going wonky.

I've had an alternator fail in my previous car and it drove 20-30 miles before it cut out due to the battery depleting so much that the lights dimmed and there wasn't enough power left to run the fuel injectors etc.

However, this was in an old 02 volvo S40. Current cars with CAN bus etc likely have much more interplay between components and a failure in one place might have an unexpected or confusing effect on another component that would, on the face of it, appear to not directly connected with the failed component.

Sure just look at how many threads there are here where the owner will get a MIL, and limp or no start and pull a fault code for some part engine system. Then after much confusion, it turns out it is actually a left rear brake temperature sensor or some other random unconnected part is actually causing the issue.

I think auto companies have a lot to do on the robustness and reliability engineering side of things.

Thanks Del2005, yeah I didn't have the experience of driving pre power assisted steering. At 6'3"/191cm with an athletic build it took me by surprise! This felt like the two front tyres had deflated/blown out (which is what I checked first when I got out of the car). The only other time I experienced something like this with a car was when the hydraulics were no longer working on a boot door - by God you only realise the weight then!

Thanks James, after it happened I was looking for warning signs but there was nothing new illuminated/flashing which I found odd.

That assumes the battery is healthy. It seems the power steering draws a lot of power which explains why that was the first thing to fail. Why there was no light on the dash... I have no idea.

Your failed steering was far far harder to turn than cars of old. Fighting the now dead electric motor being the main cause. Anyone would have found that difficult.

Thanks Midnight_EG, authorised dealer billed me and claimed they were doing me a favour by providing the option of a reconditioned alternator instead of having to pay more for a new one! I assumed it would be well out of warranty due to it's life and was more concerned as to whether it was a manufacturing fault.

This is what I was going to say. I've plenty of experience of driving cars that didn't have power steering including some quite large and heavy ones with wide-ish tyres, so know what it feels like, but on the two occasions where I've experienced power steering failure it's felt much, much heavier than that.

Thanks Alanstrainor, the worry just comes from not knowing whether any other source of electrical failure (eg. battery failure) could occur and result in the same outcome. It seems that based on the responses so far that I would indeed have been better off at speed. Incredible force when moving from a stopped position!

I've been told this tip before and without opening up another thread... I struggle with the insurance/legal ramifications of taking it to a "good independent local" if they are more limited in the scope of their testing and responsibility. If, worst case, the car is involved in someone's death/serious injury by accident (in which case the car will be forensically examined), I would much rather be standing up in court saying an Authorised Dealer looked at it, provided a report of work completed and signed off on the job rather than Joe Bloggs around the corner from me fixed x,y and z but I don't have any/much proof of what was/wasn't done.

Thanks TheBoyConor, now there's a new term for me: 'fail-deadly' in a military context: "In nuclear weapons strategy: encouraging deterrence by guaranteeing an immediate, automatic, and overwhelming response to an attack, even if the command-and-control infrastructure has been damaged by the enemy's first strike."

Thank Toyotafanboi. Goodwill is discretionary living up to ‘best built cars in the world’? is an expectation.

I guess this failure just caught me by surprise as the car had only recently been serviced and showed no warnings before or after the alternator failed.

Defo, got a big fright!

I accept the alternator can go after 14 years of use and I am grateful for it lasting so long. It's more just the knock on impact of it's failure that is hard to rationalise!

Isnt that what the nct is for.
An inspection saying the car is safe for use on the roads.

To be fair as well the main dealers will have better technology in the most than indies for the newer stuff but for the older cars an indie would be just as well equipped.
And there are stuff that the main dealer wont touch that indies will

The NCT is a rough check that major bits aren’t about to fall off and of course emissions.

If the NCT were expected to test everything down to “will the alternator stop working”, the rest would take about three weeks and cost about €5,000

It’s an older car, something broke, OP got a bit of a shock, it’s fixed now, life is good, move on.

Expecting it paid for is laughable

14 year old car and only this happens ?

Don’t ever buy a Citroen

tsue921i8wljb3

This happened to someone I know recently in a MK5 Golf which also has electrically assisted steering. She maintains the car was totally undriveable when the steering failed and like Toyotafanboi said she actually thought the steering had locked. I didn't get a chance to experience it to see if the wheels were in any way moveable but if a large guy like the OP is struggling I guess they aren't.

zoe 3619

Does the alternater maybe drive a power steering belt which might need tightening or adjusting if it doesn't feel right ?
Oh,sorry.Re-read your post.
If the alternater is replaced,then I imagine your good to go.No reason for the problem to reoccur.

If the alternator had failed, there should have been a battery warning light on long before the steering lost power, it’s only when the battery is nearly discharged that the steering thing happens.

Not in my case anyway. There is no power steering pump or pulley. As far as I know the power steering in the MK5 Golf is a sealed system driven by an electric motor.

People are making small of this but imo it's a dangerous design if power steering can be lost without warning.
I can easily see how this could make a driver take a wider than required line into a bend. If that was to happen at the wrong time, it can certainly lead to an accident.

Yes but you keep on top of tyre maintenance and actual blow out is very very rare and a slow loss of pressure is easily picked up when driving.
Suspension collapse is not going to happen in a maintained car.
This is a zero warning, be it car feel or anything else.

Ah lads, the alternator went. It happens. Nobody to blame, no compo to be gotten, no reason to go down the "somebody please think of the children!!" route. Mine bit the dust on the way out of Dublin last year in a 2 ton landcruiser, fully loaded in the back too. Took my time and got it home before the lights died. OP's car may not have high miles but the engine may have run for a long time with town driving etc.. the bearings go. If you were that scared, then stay put and hazards on, and wait for help. I don't buy the life threatening bit in this situation as described.
