So, we didn’t make it to WonderCon today. We got out later than planned, and ended up hitting rush hour traffic in San Jose, which cleared up after a while, but dropped back to parking lot status as we approached Downtown San Francisco. By then it was raining pretty steadily as well.

Then I made the mistake of relying on Google Maps for directions to the hotel. One way streets, poorly labeled streets, streets where cars have to share with cable cars, trolleys and pedestrians… We missed our turn at one point & had to go around a few blocks to get back on track, then got stuck on Market Street where we could only move one carlength at a time.

Somewhere in all this, I drove over a bump. I didn’t think anything of it, since the car wasn’t moving fast enough to notice any change in how it handled. The low tire pressure light came on, but I see that in cold weather sometimes. It was only after we’d reached the hotel (on the left side of a one-way street) — and been handed a flyer with directions to the parking entrance — that someone in another car told us that the front right tire was flat.

I’ve driven a 2007-model Toyota Prius for two and a half years, so you can bet I’ve been following the news over the recalls and reports of uncontrolled acceleration. Monday’s runaway Prius incident, which involved a car that looks exactly like mine, has made me think even more about the problem.

Now, I’m not overly concerned, because the number of incidents is still small compared to the number of cars out on the road. And in the entire time I’ve been driving it, I can only think of two circumstances in which the car accelerated in a way I didn’t expect, both of them when driving on an incline:

  • The transmission has been kind of sluggish a couple of times when starting, causing a slight lurch once it switches gears.
  • Hitting an incline with cruise control. The car has to work harder to maintain the same speed, so it feels like it’s accelerating.

From what I’ve heard previously, the acceleration problems have had to do with malfunctioning cruise control, and I don’t really use cruise control anymore. (Not since I realized that it wasn’t a good fit for actual driving conditions.) Annoyingly, none of the articles I’ve read about James Sikes’ experience say whether he was using cruise control at the time or not.

They do say that he wore out the brakes, but refused to turn off the car or put it in neutral (as the 911 dispatcher advised him during the 23-minute call), and finally got it under control when a CHP officer had him apply both the regular and emergency brakes together.

So, what to do in this situation?

  • Brakes aren’t enough, but they’re a good start.
  • Turn off cruise control if it’s on. Some reports of cc-related problems have said that tapping the brakes didn’t disengage it as it’s supposed to, but manually disabling it did.
  • Putting it in neutral should cut off the engine from the wheels and still leave you steering. Sikes’ reason for not doing this when the dispatcher told him to — that he was afraid the car would flip — doesn’t make any sense to me.
  • Turning the car off locks the steering wheel, or at least turns off power steering. Not ideal for 90 MPH, so I understand Sikes’ reluctance here, but if the computer has essentially hung, push-and-hold for a hard shutdown might be the only thing you can do. I’d rather skid to a stop with minimal control than slam into a wall at 90.
  • The parking brake can double as an emergency brake. It might not stop you completely (it didn’t for Sikes), but it should help get the car under control again.

I don’t expect any trouble, just based on statistics, but at least now I have an idea of what to do if I ever do find myself in this situation.

Follow-Ups

Update (April 14): Toyota finally settled on a fix for the Prius stuck-accelerator pedal recall beyond “remove the floor mat”…five days after I took mine in to get the alignment and 30,000-mile maintenance done. (Also: After driving a Prius for 2.5 years, driving a normal car is weird!) (FB/T)

Update (April 15): Prius recall dealt with. Free fix, free rental, and choice of a $50 service coupon or $10 Starbucks card. Easy choice there. (T)

Update (July 16): A U.S. Department of Transportation investigation of Toyota crashes blamed on sudden acceleration has implicated driver error in nearly all cases. Of the 75 fatal crashes investigated, only one could be verified as a problem with the vehicle: the Lexus crash last August in which the accelerator was caught on the floor mat, leading to a recall. Of course, the court of popular opinion has already made up its mind. (#)

Update (February 2011): Even NASA engineers didn’t find any electronic problems causing sudden acceleration in Toyotas. It looks like the sticky pedals and floor pads were it. (#)

I’ve pulled in a few updates from my social media archives and from round-up posts I made here. It seemed the best way to consolidate the story into one place.

Gee, that was “fun.” It’s not every day you get to dodge living room furniture on the freeway at 65 MPH.

To clarify: It was an easy chair, sitting in the middle of the road. The pickup in front of me slammed on its brakes to avoid it. I slowed down and tried to move into the next lane — around the car that was pacing me — so that I didn’t end up getting plowed into by the giant truck behind me. (It takes a long time for those things to stop!)

What genius decided dark green on black was a good way to mark up parking spaces? To make matters worse, some of the spaces actually are 20-minute spaces…only they’re labeled on the ground, in the same color green paint. I was almost into the space before I noticed.

Judging by the commercial, Ford’s hybrids are hippier than the Prius. And I say this as the happy owner of a Prius. Seriously…the size of a tree indicates energy efficiency? The Prius has a bar graph.
