| We have a Forester and we were having a devil of a time getting it to start in COLD weather. It had a very rough start that required us to keep tapping the gas pedal so it wouldn't stall. We took it to the dealer last week and they said Subaru had just issued a recall on the air flow sensor/thermostat (?). They replaced it free of charge and things are back to normal. | |
| I'd agree you can have a number of causes for warped rotors, poor design being one of them. But I still think over-torquing the wheels (not necessarily by Subie dealers) is the main culprit. In fairness to my dealer and Subaru, they only turned all four rotors after the braking vibration in the front couldn't be corrected to my satisfaction. But I've had the same kind of problem crop up with a previously owned Toyota and BMW, so I think we're all on the right track in saying manufacturers in general need to beef up their disc brakes to better meet the demands of daily driving. | |

Or if shops are bending the rotors that easily (I mean, by now you'd think most shops would know this common error), I think the factory should beef them up. Not starting in the sun -- I suspect that the sun and the starting problem are not, in fact, related but coincidental, since engine heat would create lots more heat than sunlight. So the car should fail to start with a hot engine if heat were the sole issue. Make sense? |

| Thanks everyone for your input on my brake issue. I still am not sure what to do with the dealer though. My warrantee just expired -- so am I now to pay for rotor turning (or replacing) every 17,000 miles? I have tried emailing Subaru directly, but have not received a response yet. | |

This is not a story about a Subaru, but it does touch upon the heat/start issue. My brother had an old pickup that had had some restorative work by an idiot. The truck would start cold and run like the dickens (meaning "well"). But if you stopped the truck, frequently it would not start until it was cooled off -- though one could get it to start if you pushed it, or let it run down an incline. The problem was a fuel line too near a manifold. If the engine was running, enough fuel went through to keep the stream from being interrupted by "vapor-lock". Once it was stopped, the fuel vaporized and the truck would not start unless fuel were pulled through the line again -- pushing the truck or coasting down an incline. Perhaps a hot sunny day could be effecting the fuel line? |

I had the front rotors on my 2001 LLBean turned at 10K due to shake and noise. Subaru replaced them (and the front pads) at 23K (now have 25K). They said the rotors had "hot spots" - a manufacturer's defect - areas where the metal was different, and therefore wore differently... Who knows? I think it may be a design issue - they don't seem to like stopping 3750 lbs. (plus passenger/cargo weight) at 80 mph off an exit ramp. I have to slow down one of these years. Otherwise, car has been flawless. Ralph |

Didn't they just go to bigger rotors up front? I think in 2002. The H6s may have gotten them in 2001, though. -juice |

| I can see where it would seem that it was a coincidence about the hot weather, but it has happened time and time again. Never in the spring, fall or winter, and never when the car is in the garage. But once summer rolls around, and the car is left in a hot parking lot, it happens frequently. And that's JUST when you don't want to be stuck. | |

Ah, but you see, you had to drive it to that parking lot, right? So the issue may not be the sun but engine heat in general + summer ambient temperatures. What if you left the car for overnight and then let the sun shine on it (with cold engine underneath)? Have you ever experienced a no start with the engine not running for 24 hours and left in the sun? My problem with accepting your theory is that I do not see how the heat of the sun alone could cause this. I'm not saying absolutely you are misdiagnosing, I'm just extremely skeptical at this point without some solid field testing of the problem. |
