Loud ping when selecting reverse
I have a Feb 2010 1.3 5dr Yaris YR Auto with 1,500 on the clock. At 1,000km service I advised dealer of a loud, intermittent ping when placing into reverse (it sounds like it's coming from somewhere in line with the wheels), particularly when cold and following being parked overnight (it's parked on flat and almost sounds like some sort of metal pin disconnecting). They adjusted the brakes, however, still have the problem and seems to be happening more frequently. Have contacted the dealer and going back to see if they can determine the problem.
Any advice. They don't seem to be aware of any existing problem. |

Had the breaks all checked and that seems to be OK. It sounds more like a metal spring of some kind .... or like something that has a metal pin in it if you pull the pin out quickly it makes a ping sound.

My auto did that while new. It went from the loud "ping" you describe to a click and now is quiet. Things just have to break in a little and you'll be fine. I don't blame you for being concerned about it-it was disheartening for me as well. I'm at 9300 now and so far the trans has been flawless other than the noise you describe when shifting to and from reverse.

Dropped off Yoshi to the dealer (have taken it in three time but the noise has been intermittent and each time I take it in .... no noise). Left it overnight as noise mainly happens when the car is cold and they finally heard it this morning. Their first diagnosis is that it's something to do with the brakes so they've re-coded the computer. They're going to let it cool down and then see if that's fixed the problem. Will keep you posted and let you know what the final diagnosis and 'cure' is.

I wonder if "recode the computer" means "let it sit overnight so you think we did something and hope you go away" in austrailia too.
Its your parking pin. Pull the parking brake harder and/or park on level surfaces. Also, when parking, put the car in N, pull parking brake, release brake pedal, put in P - this puts all the weight on the brakes, not your parking pin. |

did you log a call with toyota customer care in your area, because they would send out a toyota engineer to help the dealer find the problem and help them sort it out as they cant fix it, here is something u can also do check if there is enough gearbox oil, also they must check engine mounts, as our cars are front wheel drive and we have no propshaft to turn the rear wheels let me know what happens,

Yoshi,
My theory was always that the bearings on the axleshafts were tight when new so when switching from forward to reverse (or vice versa) they would "load up" and release suddenly, creating the noise. Therefore your observation the noise occurs inline with the wheels would be spot on. Why they are investigating the brakes and what not is beyond me. The important thing is you've brought it to there attention. You're under warranty so I'd drive it a few k mi and see if it doesn't go away. Judging by the related posts here, I'd say its fairly common. I understand your concern-I think you'll be okay! PS-that sound is how my Yaris got its name! R2 |

Thanks to all for the posts. Picked up Yoshi two days ago and told that re-coding done, brakes removed and checked, park pin mechanism checked and some general tightening of firewall materials and exhaust brackets. Although they did hear the noise it seems to be a bit of a mystery as to what's causing it .... particularly as it's intermittent. The car needs to be left sitting for a couple of hours before they can get it to make the noise again. Makes diagnosing the problem a pain in the .....!!
No noise yesterday but, low and behold, it's back this morning. So, back to the drawing board for Toyota. |

Back to Toyota today, with the noise back in full swing every morning. Fortunately they have arranged a courtesy car for me so they can keep Yoshi for as long as it takes to resolve. Thanks R2D2 for the suggestion re bearings, which I'll mention to them this afternoon.
Poor Yoshi. I'm sure it's not anything too major, but it's a brand new car and shouldn't be making the noise. Will keep you posted. |

Yoshi's coming home today and she's all fixed.
So what was wrong? Toyota were able to get the noise to consistently occur by reversing then braking hard. Once they changed gear to drive they would hear the noise. Same thing would happen if in drive, go forward and then break hard. They had a couple of tech's on either side while doing this and were able to ascertain that the noise was coming from the right hand front wheel somewhere. They stripped down the right hand front and have just called me with the outcome. Yoshi is now fixed and no noise at all after they replaced the drive shaft to the front right hand side with a new one. Toyota Service explained that the female / male spline assembly wasn't machined properly (which would have occurred in the factory) and hence the two splines were "rattling" against each other when the drive shaft was changing direction. Toyota said it's been a bit of a "curly" one to solve. Fortunately, I'm a female who spent her youth watching dad fix cars and I learnt enough to know that what I was hearing wasn't normal. Thanks Dad :) |
