Advice: pulling to the right. Warranty?

Check your tyre pressures first. Whatever you run them at, the fronts should be the same, so should the rears. And of course they should be sticker values or higher. Use your own gauge, don't rely on a gas station. If you don't have a pump, get one and set your own pressures when the tyres are cold.

It could be alignment, but you would have had to hit something major (big pothole, 4x4 , traffic island etc) - you would remember doing it. Wear n' tear wouldn't be covered under warranty.

Have you any steering wheel shimmy (shaking)? Lost any balancing weights off your wheels?

The C is quite a high car and wanders a bit in cross-winds; had a lot of wind lately?

Eyeball your tyres to see if all looks OK I would jack up each wheel in turn and spin it to see if anything is binding, like a brake caliper.

The more you do and know yourself, the less you are at the mercy of the car trade cowboys. If you have to call on their services, try to identify a car behaviour that you can reliably reproduce, and show them. Otherwise they will charge you for fixing what they think it is, even if they are wrong.

 

I know on the 2010 models Toyota would do a free alignment within the first 12 months or 20,000 miles. I would call your dealer and verify if this is still true for the c.

Also, check your Warranty Manual. I just checked mine and it is in my manual.

 

They don't do that anymore.

 

Some further thoughts

Even with an minor alignment problem you aren't going to do any harm by putting off fixing it until a scheduled service - at worst you might start to get a little uneven tire wear.

Regular driving at sensible speeds for the conditions won't cause problems; cars are too strongly made for that.

Do you notice this more when the camber of the road is more pronounced? On the interstate, the right lane is cambered to the right, and the left lane to the left - is there anything detectable in either lane?

Is it worse when you brake?

Drive on a empty large flat parking lot, and release the steering wheel - if the car clearly runs off to the right, then there is likely a pull somewhere in the steering or suspension.

Try swapping the front wheels to see what (if any) difference it makes....

 

The roads in your area are crowned in the middle so water runs off; if your car wasaligned on flat level ground it will indeed try to drift right down the inclined surface.
Find some deserted place and drive down theleft hand side of the road to see if it then veers lefet. If thats the case your car is good and having to steer left is normal, unless its more than 2 inch f a turn of the steering wheel. If its more than that its up to your dealer whether re-alignment isfree or paid for.
cheers. good luck.

 

I seem to remember some people posting about this problem when the c first came out last year. Search "Prius c alignment issue" to find the old thread.

 

I would check tire pressures, I know mine was doing that and the shop foreman told me that the car has memory steering, something about the car remembering its last steering wheel position regardless of how slight.

In any case they realigned the vehicle and did a cross rotation and adjusted the tire pressures and it seems to be fine now..

 

That is a new one ! steering wheels with memory... and no, folks, wheel alignment isn't warranted for more than a hundred miles. In other words detectible right after the alignment.
