One of the primary concerns I had when one bought this car was about reliability. Was OK with odd niggles, but not with a
breakdown. Given how much I liked this car, I was not as much bothered about this car getting discontinued, as long as the parts/service was available.
So, there I was one day, a hundred kms away from Delhi, on this unexpected short day trip, walking out of the car and to my horror, seeing a fluid rapidly flowing from under the car. Was aghast, as it was very important to reach Delhi back the same night, preferably before nightfall. It was well into the afternoon then.
Anyway, after a brief check under the bonnet, called up the service manager of the dealership; also the Service Engineer. They were nonplussed about what to do, as I was quite far - seems they were a bit embarrassed to say that they can't help me and I should call the helpline. Tried the GM helpline number once. Didn't get through on first go. Not wanting to waste time called the fellow one kind of knows in GM. He immediately got the wheels moving. Was fortunate that we had reached the destination for the afternoon, so one didn't really waste much time on that front.
A temporary diagnosis made over the phone was that it was an HPS fluid leak. Was also specifically told not to use the car, as running the HPS pump without fluid would damage it too.
To my surprise and delight, within about 2-2.5 hours, someone from NCR drove down all the way from one of the A.S.S. This, when their regular service car of the dealership had gone to attend to another complaint. Apparently, a car was arranged from the GM office to get the mechanics to the VVS. Was very impressed. They also didn't send people from the nearest ***, which may have been more convenient for them, as they were a lot more confident of the NCR chaps, to handle it well. They were very professional and did the job in about half an hour, as was informed on the phone. The issue was tentatively diagnosed over the phone as a leak from the Hydraulic Power Steering, which it was. They had carried the tools, parts and consumables for it. The fellows knew exactly what to do. Was also impressed with their attitude.
Steps followed- Removed the pipes to and from the pump.
- Cut tiny bits of the ends (as needed).
- Refixed the pipes with stronger clamps (which they had carried)
- Ensured there was no air left in the system (described below)

Not a penny was charged. The small amount of HPS fluid which remained, was also left with me, for a Top-up, if needed.
After pouring the fluid, one also needs to make sure that there is no air left in pump-pipe-hps system. For this, the car was started for a short while, and the steering wheel moved from one extreme to the other repeatedly for a few minutes (I pushed them to do it for a bit longer, just to be safe).
Now, the other info one got was that it was something happening quite regularly to the current lot of Optras. It was something very easy to correct. ust putting better clamps to the pipes to and from the HPS pump.
Suggestion to fellow Optra Owners: Do not wait for this issue to strike you. Simply get new and stronger clamps fixed. It is an easy 20 minute procedure. The A.S.S. fellows should know about what needs to be done (if you live in a metro), since it is a known issue. It may help, if one was to take up the issue gently with them, rather in a confrontational manner. It could save you a lot of trouble.
Note: The mechanic had also enquired if I had given it "raise" (increased the RPM) with the steering fully on one side; suggesting that the issue could get triggered with such an act. I think I read about Vento's too having some guideline around this. Probably an issue with other cars too. Would be prudent to avoid doing so, till one gets stronger clamps.
The Good - GM attended to it so very well. Even when one was far away from town. It gives me a lot of confidence with GM service. (other good developments too, which I'll share later)
The Bad - The problem happening in the first place.
The Ugly - It seems to be a known issue and very easy to take care of. One can't excuse GM for not doing so at the factory/PDI/Service level.
