Toyota engineers have worked hard to get the emissions that come out of the tailpipe of the Prius V down to a low level, but that doesn't mean everything is copacetic with the car's exhaust system. To fix a known problem, Toyota has announced a service campaign for the Prius V, both in the U.S. and Japan.

The Wall Street Journal reports that the problem is with "weak actuators-control mechanisms" in the exhaust-heat-recovery systems that can end up leaking engine coolant, which will then force the car into a "safe" mode. Some second-gen, 2004-07 standard Prius models were affected by a similar problem in the past.

The new issue affects about 8,000 vehicles in Japan and 20,000 in North America. Prius V owners will get the problem fixed for free.

      Toyota's customer service is outstanding, if this were GM they would hide the issue like they always do.

        Right, because Toyota was so open and transparent about their engine sludge issues, their issue with Tacomas and rusting frames. It was only because the NHTSA intervening that it came to light about the unintended acceleration saga.

          Thanks, Sj. I was going to say the same thing - a service campaign is a nice way of saying "recall" for a product defect.

          Huh? Toyota voluntarily bought back all those Tacomas you claim they denied having problems with, at 1.5x KBB value so I'm not sure why you'd claim that as a problem. And they paid 1.5x excellent condition value even though most of these trucks were trashed.

          Funny how the detroit fanboys always bring up sludge or rust when they talk about Toyota. Wanna know why? Because they can't find anything else to talk about! If you were to do the same with Ford, GM or Chrysler there'd be way too many incidents and coverups to name. And that unintended acceleration BS again? Really now? Ugh.

          SJ, When I was in Afghanistan, we used Tacomas because they were far superior to anything from America. http://www.militaryphotos.net/forums/showthread.php?57724-Toyota-A-Stan-and-special-forces Here are a couple of different articles about the durability of the Tacoma. http://www.thedailybeast.com/newsweek/2010/10/14/why-rebel-groups-love-the-toyota-hilux.html You really want to talk engine sludge? Here you go. http://www.f150forum.com/f4/you-want-see-engine-sludge-74045/ https://www.google.com/search?q=ford+engine+sludge&sourceid=ie7&rls=com.microsoft:en-us:IE-SearchBox&ie=&oe= And now rust? http://wheels.blogs.nytimes.com/2011/01/26/prone-to-subframe-rust-425000-ford-windstars-recalled/ http://www.autoguide.com/auto-news/2012/03/jeep-liberty-recall-of-209000-units-over-rust-issue.html http://articles.boston.com/2011-08-02/business/29843258_1_cold-weather-states-f-series-pickups-lincoln-blackwood-pickups I am not going to say that Toyota is perfect because nothing or no one is. However, they are far superior to their domestic counterparts.

          Tacoma is the only vehicle I've ever heard of that is built so bad that the company has to condemn them.

      What are we back to kissing Toyota's butt? Its a Recall!

      Oh, you mean a RECALL.

      If it sounds like a recall And it smells like a recall It must be a RECALL, regardless of how the PR guys are calling it. But at least it the throttle doesn't get stuck on wide open anymore.

        Yeah, they never got stuck open. That was proven to be bad/inexperienced/neglectful drivers. "I swear I was pressing the brakes as hard as possible!" We all know the brakes would overpower the weaksauce engines in these plebeian Toyota commuters.

      "service campaign" riiiiight....

      I believe the primary difference being a recall is mandated by NHTSA for a potential safety defect, and a TSB or campaign is completely voluntary.

      Grumble, rofl, cheap stupid foreign cars, go America, I got $100K doing nothing and sitting at home. There, I think that covers all comments necessary, so no need to write more comments. Seriously.

      "service campaign?" I would interpret that as "recall."

      Wait, exhaust? I thought Prius REMOVED pollution from the air as it drove. Are you saying it CREATES pollution? It can't be.

      ok, is this feature of exhaust heat recovery used in order to warm engine up faster to reduce emissions ? My concern would be another opportunity for cooling system failure as car ages - anyone have an knowledge of how this works ?
