Might I add ... it is atrociously horrible

I had IMA Battery Error message on my Jazz Hybrid.
I sent it to the dealer I purchased from in 2012 since it has all the of the car's service records.
The diagnosis is the inverter intelligent unit , costing RM10,000 is faulty and needs to be replaced and it will take 3 days.
I repeatedly ask for confirmation, since it is quite a hefty bill, if this is truly the fault and every time the answer from the service centre is affirmative.
Not satisfied, I seeked a second opinion; this third party workshop not only diagnose but verified correctly the fault and repaired the fault for RM1000 in less than 2 hours.
The car is now running well.
The fault is the IMA battery fan that has shorted, not the inverter that cost a bomb.
If I had proceeded with the repair at the service centre, not only would I have to foot a hefty bill but the true fault would not have been rectified either.
On one hand owners have to have their cars serviced at service centres , to avoid voiding warranties ; on the other you have service centre such as this that is incompetent and unethically mislead customers.
Makes one wonder how many car owners would have been taken for a ride given the service centre's incompetence.
It is real sham and shame on Honda
