The problem:
During a routine repair my local garage managed to lose my car keys and more importantly my alarm fob and override key. This now required the car (Shogun 3.2 DiD) to be taken to Mitsubishi for new keys and to have new fobs re-coded. Whilst Mitsubishi were waiting delivery of the new fobs and override key they disengaged the alarm system and immobiliser system so the car could continue to be used. Now here's the problem, ever since they disengaged the alarm and immobiliser starting the engine had become more and more difficult. The cranking speed has gradually slowed with each start until today when the engine wouldn't turn at all. Mitsubishi have now declared the starter motor seized and are quoting £400 for a replacement. My question therefore goes to who is responsible for this invoice. Is it possible that there has been some sort of error that could have “spiked” the starter motor and therefore the garage is responsible, or am I just the victim of a bad coincidence in which case I'm responsible. Either way I need the car working so Mitsubishi are going to replace the motor and invoice the original garage. They will then do an autopsy on the old motor to see what happened.

coincidence

I would say the same but immobilisers are very complex on modern day cars for example I recently removed a standard stereo on a jag x type and the car wouldnt start with it removed, totally dead no electrics at all, replaced it and it was fine. But as for it effecting the starter motor I doubt it m8 but you never know.

sounds like coincidence, starter motors don't normally seize up, but if the engine is being cranked over for a long time without the engine firing up, then the starter will burn its self out or maybe the starter has engaged itself whilst the engine was running & continued to run, thus knackering it.

I'm sure I just saw this same thread in the deal section!???

Sorry hun......am as usless with cars as I am with computers!!

Seems too much of a coincidence in my opinion tho x

coincidence also check the battery that is probarly weak

Sound's more like a dodgy battery or alternator, If it's not charging or it's discharging then it would cause the starter motor to turn slower as it's not getting enough amperage hence slower cranking.

It could be a faulty starter motor but I'd have the battery and alternator tested first before forking out £400 for a starter motor...!!!

If you can't have the alternator tested at least get the battery tested, Usually free at car autofactors.

Mitsubishi put it on their jump starting machine 260 amps, four batterys in a row and it still wouldn't crank, bviously proving the motor is seized. My question why all of a sudden when the car turned over fine before they disengaged the alarm.

I suppose their could be a link to them disengaging the immobiliser and alarm, I've heard of similar issues in the past.

When the immobiliser is active does it still try to crank over? Obviously it wouldn't fire up but they sometimes turn over still hence could essentially burn out the starter motor, I'd still guess it'd be hard to prove though.

Electrics are funny things and the ECU is even funnier.

Now thats crazy! I would love to dig into that one further and crack why, wonder of it would start if you removed the fuse for the circuit the radio is on? IE. A passive circuit that needs to be there, pity the poor driver who gets his stereo nicked.

no link that i can think of, you apply 12v's to the starter and it … no link that i can think of, you apply 12v's to the starter and it turnsbattery should flatten before you burn a starter out turning the motor over



not always the case, seen it loads of times, customers trying to crank their non starting vehicles over & over & burning the starters out, try turning a diesel motor over & over again without the engine firing & see how much smoke starts to pump out of the starter motor !

Thanks everyone for your help and advise. Had to bite the bullet and pay for a new starter motor.
