Runaway Acceleration And Starting Problems With Aygo Blue Mmt, 30,000

January 5, 2014

STARTING ISSUES.

Thought I would update you guys on here, Main Toyota dealer did OBD DTC diagnostics and found error codes P0909/P0919 = These are batched together 1) Select actuator or its circuit. 2) Shift/stroke sensor or its circuit. 3) Shift actuator or its circuit. 4) Select/stroke sensor or its circuit. Its a wild guess which one even for the professionals and they have quoted £1250 just for the Gear shift select actuator to be replaced on its own. BIG BUCKS ££££££££££££££. I've done my research and found out the codes etc. Anyone else got any answers?????

RUNAWAY ACCELERATOR ISSUES.

Toyota are investigating this one, main dealer didn't have a clue. The dealer checked the recalled parts on the accelerator pedal block etc that had been replaced at recall and they were OK. My main concern is if it happens again! Just to recap: when foot totally removed from accelerator and then placed on brake the Aygo accelerated just like an old car (Cortina) etc with jammed accelerator cable, not just revs but actually moving forward faster! i managed to stop the Aygo with the handbrake and the revving stopped as the car skidded to a halt inches from the stationary car in front. Anyone got any ideas. With no disrespect to the elderly I was not depressing the accelerator pedal with big paddle feet at the same time. I am young(ish) fit, driven for 30 years with no disability or duck paddle feet. Anyone got any ideas as this could be quite serious if it happens to anyone else who wouldn't think to use handbrake to halt the car!!!!!! Thanks all.

LEAKS

Also had the leaks coming in from rear, I have sealed rear roof brake light, still small amount coming in but seems to have cured, next stop rear brake clusters!!!!!!!!!

and a very scary experience tonight which is really wierd and bizarre. I will explain in a moment.

In family I own 1995 Civic, daughter 98 Micra, 1975 VW camper and I have driven many vehicles.aquired the vehicle in 2012 from mother in law, with 18,000 miles on clock. Now has 30,000 miles on clock. Problem is exactly as Aygo Girl and the others posted on this forum. Vehicle does not start when brake depressed, brakes seem jammed and solid. No tickover, no starter. But you can here a electronic clicking sound from the selector area of gearbox. No light on selector unit. Left it about an hour and it seems to reset itself and starts first !Removed! time. Last time it happened last week and I made my way home by train, left overnight and it started in the morning no problem first time.

Next wierd thing is this: driving along at approx 45mph, In (E) normal gear change OK. Had been in E all the journey. Approached a junction with a pickup truck in front of me. I slowed by taking foot off accelerator, then depressed brake to stop. Next thing the car accelerates and increases speed with my foot depressing the brake. I stopped the car with handbrake. I nearly hit the pickup in front. I was not driving to fast and the car seemed to have a mind of its own. Now I have driven manual/autos all makes and models since 1984 and I have never experienced anything like this and not only dangerous but seriously shaken. My foot was def on the brake, nothing near accelerator, no mats caught. The car was recalled in 2010 and had rectification by Toyota dealer. My feet are fit and healthy and I know what my feet were doing. Summary: Car accelerated away while foot depressed on brake for an instant. car raced away. Once stopped it didn't happen again and normal drive home. We have also suffered MMT struggling to decide which gear to be in and lagging when accelerating. I am baffled and want rid of the car. My Civic has never let me down once in 12 years. It is now 18 years old and looks 3.
