Couldn't find a Bangalore Carnation Thread so posting my experience here.
This is going to be a long post so get some coffee or tea before you start reading the whole thing.
After all the horrible reviews and my previous bad experience with carnation we thought we could give them another try.
Gave our old car to them for a routine service.
We carried our own oil with us.
Problems reported by me - None,
Parts to be replaced, air filter & oil filter and any damaged parts if needed and general topups.
Rotate the tyres.
SA attending my car knew absolutely nothing after hearing the engine recommended a belt change as it was a little noisy, Luckily the floor supervisor who was with my car at the time corrected him saying it was engine noise and all it needed was a tune up/adjustment.
Later on one of them told me the SA assigned to me was new and knew nothing, I was surprised as to why someone who knows nothing about cars is working as an SA!
They needed the engine to "cool down" apparently before they can do the tune up and said they will do this in the evening and oil will be changed at that time.
I leave this place for a couple of hours go to a near by mall and come back in 2.
I see my car sitting there with the engine fully assembled and everything ready. Few minutes later the mech attending my car comes, I ask him whats going on, According to him everything is done and the car can be taken for wash.
I ask him carburetter has been cleaned?
Answer - Yes
Egine tune up done?
Yes
Oil filter and oil ?
He says Sir everything done!
Then I causally ask him, tyre rotation ?
he mumbles something that its not in the job card,
When I ask him about the brake cleaning? he says its done!
I show him the dust marks on the wheel cover and ask him if its really done. Again I got his standard reply "yes sir all done"
Next ask the floor supervisor to check this, he asks the mech about the brakes, mech again says yes-yes done.
I show them the dust on the wheel cover caps,if the brakes are cleaned then shouldn't the whell and wheel covers be removed? Doing this would leave the cover with hand marks ?
FS (floor supervisor) had to press him harder and told him that wheel rotation is also pending and needs to be done.
Then this lazy mech admits that brakes were not cleaned and starts doing them
At this point I totally lost my trust with these and stood by my car while he was working on it, Several people asked me to wait in the customer lounge but I refused to leave my car alone.
While removing the rear wheels I saw the rubber suspension bushes were worn out and needed replacement, I kept my mouth shut and waited to see if the mech/SA or FS says or notes anything.
After he finishes ""cleaning" the pads I ask him if anything else is wrong. he shakes his round head telling me everything is over sir.
I point to the suspension bushes,
Again he removes one side of wheel and checks it says it needs to be replaced.
Now comes the next irritating part, They have no ready parts in stock.
Time required to get the parts 1 hour at max according to them.
I tell 3 people my SA, FS, the parts shop guy to order the required parts and get the job done.
3 hours later I see nothing happening my car just sitting there. Waited for 1 more and I gave up, told them to chuck the suspension job and just get my car ready so I can leave.
To make my blood boil even more they added Rs 3xx in my bill for something that was never done! When I complained about it to the SA he said come next time we will adjust it

Yeah right he expects me to go back to them after this??
This time the wash was good but by the time I reached home my boot was again dripping with water, They did not dry the boot mats before putting them back. (car has 2 boot mats) 1 carpet and 1 rubber.
Coming back to the suspension bushes I got these from a shop few clicks away from carnation, price - Rs60-80 each.
Carnation couldn't get these parts even after giving them 24 hours time!
In short the mechs here are lazy good for nothing, I have said it before and will say it again their equipment level is top quality but the mechs/people attending our cars are not up to the task.
