Now coming back to the feedback. The car has mostly been driven daily for 50 kms. I have also started car pooling while going to and coming back from office, thus zilva also do face some amount of abuse time to time in case any new members join the car pool. Zilva was initially baby'd but after first 6 months I started to enjoy the drive more than worrying about his health.
First the over all feedback -
Apart from some issues Zilva has been mechanically holding up well and have been driving tight and reliably till date. Till now I am in love with it, and my wife says I just make up reasons so that I get to drive zilve

.
All the buttons, tactile feedbacks everything is working like the way they did when zilva was new. No glitches from sound system either, it sounds as sweet as it was before. Talking of sound system I need to mention, I have started listening to uncompressed dolby digital tracks in Zilva and the surround effect is just amazing. Only thing I will have to do is convert the ac3 audios to aac format and put it in SD card and plug and play from the SD card. Also I am considering to make ways to watch movies from the back seat. The plan is to install android device so that everyone seating in the back have proper view of it and then just play it's audio via bluetooth in the harman system and leverage the amazing 5.1 sound reproduction and enjoy theatre effect in the car itself. Haven't done this yet as I don't let any one else drive my car and no use installing something which I won't be able to enjoy

.
Now all the issues that I faced with Zilva in this 1.7 years 1. The most important Loss of Power -
Issue -
As many 2014 zest adopters have reported this I started getting this issue from 6k KM's, but this vanished on two occasions when I got this issue for the first time I started
to upshift in the 1.7 - 2k rpm range and issue didn't resurface along with that I got my air filter cleaned in one of the free checkup camps. But post 14k km's after second service the issue started crop back again
and started hitting harder.
Describing the issue a bit here- The issue is very intermittent and have noticed this to happen only during hotter days and when I am driving with auto climate on with ECO mode on and temperature set to a specific. When I am driving in a constant speed in
the ranges of 55-60 in higher gears 4th or 5th for a couple of seconds the car felt like choking and started loosing speed. after 2-3 seconds it becomes normal on it's own. When this happens inititally I used to downshift to 3d gear so that i don't loose the accelaration.
After getting this issue multiple times I contacted TML and asked them the below -
"Can we have the filters checked/cleaned, the fuel pump and injectors checked and cleaned/replaced if required? Also please do check if a ECU update is available/required."
Solution -
When I was at 15882 kms They worked on this and said eveything was cleaned and nothing was required to be replaced and delivered me the car. For 15 days the issue was gone and I was starting to believe that the issue has been resolved. But on the 16th day it again started
to come back and now worse than before.
When this occured last couple of times I was in relatively congestion less road and could experiment with the issue for a couple of times. Once when this occurred I didn't downshift and just turned off the AC and the pickup was back instantly.
Another time I thought I would do nothing and see what happens. The car finally stopped with jerks with some error light in dhasboards. For example MIL, Check Engine, battery etc.
I reported this back to TML guys again. And this time also told them
to check the AC pipes/hoses since the issue instantly was gone on turning off the issue + obd log may have some error information. The TML guys called me back and said they have checked with their engineers and other related complaints and my Fuel pump
will be replaced and ECU need to be updated to RT 11. They arranged the part before hand by ordering those from Pune and upon the parts arrival took a apoointment and did the job and delivered the car just in a day (Who says TML isn't responsive?!).
Post that service (at 18600km) my oh my- Zilva is new. ECO mode with ACC seems to be pulling effortlessly even more than what it used to! Haven't used city mode post this service yet. But I will not give a verdict issue is gone unless I drive for atleast couple tankfulls or 1000kms.
But currently the car is more eager than before silent and smooth.
2.Clock sync issue + playlist issue in Harman system -
Issue -
System Clock used to get slow by a couple of minutes everyday . Also when playing media through SD card if I was in 99th song of a 100 song play list and I recieve a call through bluetooth, the play list used to resets after ending the call and started from song 1 again.
Solution (Complained & serviced at 15800 km )-
Got the Harman system updated to 9.2 and both the issues were solved.
3.Left side wing mirror vibrations
Issue -
Left side wing mirror vibrated while going over uneven roads thereby producing a irritating noise from there.
Solution (Complained & serviced at 15800 km and 18600km) -
When this first appeared they adjusted and tightened the settings of the mirrors and it was gone but again after 2k km's it came back. When I went for the last service for the ECU update and fuel pump replacements they tightened it again. Will ask to replace
the part under warranty if this comes back again.
4. Dis-engaging clutch at it's biting point makes a weird kat kat noise
Issue (Complained & serviced at 15800 km) -
In b2b traffic sometimes (very intermittently) dis-engaging clutch at it's biting point made a weird kat kat noise which was not present previously.
could be heard only with windows fully closed and AC on. Seems like some thing is loose and is vibrating down in engine bay.
Solution - This still happens sometimes, But have found a way to prevent this - pressing the gas a little bit while releasing clutch doesn't let the sound appear. People who are more experienced- Was I driving wrong by not pressing gas while releasing clutch? Normally
Zilva starts to move forward just by releasing clutch and i used this extensively in b2b traffic scenarios
5. Left side back door lock lost the feel(that click sound when you open the door) of opening.
Issue - Since we car pool and there were a couple of people who used to repeatedly thumped the door while getting out from left side. This issue occured mainly due to that and since the audio feedback was not there people were having a tough time opening the left door
when sitting iside.
Solution (Complained & serviced at 15800 km ) -
The lock screws were adjusted and the issue have been resolved.
6. Vibration and sound from different parts of the car while going over uneven surfaces at speeds greated than 60 kmph
Issue - Suddenly felt car is not as silent as before and have lost it's smoothness. Complained to SA when went to get teh fuel pump replaced.
Solution (Complained & serviced at 18600 km ) - They sorted all kinds of noise and car is now super silent as before, only the bumps and the thuds when going over bad roads. He said all he had to do was some tightening of screws.
7. Vibration when car was in neutral
Issue - The car started to vibrate a lot when auto climate mode was on and it's in neutral. Normally happened in traffic.
Solution(Complained & serviced at 18600 km ) - SA said the ECU update and the fuel pump change have solved this. Now I can't make out if ignition is on without AC, but with AC there are a bit of vibrations yet. Have told them will gethis checked up when I go for service
the next time.
8. Kach Kach sound from driver side suspension
Issue -Very faint Kach Kach sound from driver side suspension when going over uneven roads slowly.
Solution (Complained & serviced at 18600 km ) - Have reported this and they said no sound can be found and they tightened the suspension bits, but in the bill I saw they have tightened passenger side front suspension - either I have miscommunicated or the SA didn't understand
will have to take this issue up in the next service. Or do i need to get this thing checked ASAP ?
9. Rusting in dicky lid
Issue - The place where dicky lid meets the beadings and where water gets trapped that contact point started rusting.
Solution (Complained & serviced at 18600 km ) - They removed the rust, treated the panel and made it new, pretty impressive I must say. SA said Rusting won't come back and this is a permanent solution.
10. Kach kach sound when slowly driver side door is opened
Issue - Kach kach sound when slowly driver side door is opened. Seems it's joint is being continuously rubbing with the rubber beadings.
Solution (Complained & serviced at 18600 km ) - All the doorlinks have been worked upon and the noise have been solved.
11. Tail fog light loose
Issue - Tail fog lamp was loose and was coming out of shell on vibration. Effect of a bike hitting by bumper.
Solution (Complained & serviced at 18600 km ) - They replaced the tail fog light shell. Currently as good as new
Out of these 11 issues 6 were solved at the service on 15800 km and rest of them came post this service and they were taken care of at 18600 km service. apart from issue no 7 and 8. These have been communicated and will be worked on the next time I take the car to service.
Over all service experience has been pretty good till date. They have been very responsive, have updated from time to time regarding the proceedings and have been fast. At the most I had to keep the car in service center for 3 days for a insurance claim which involved a body shop work when a uber
overtaking me from left in a turn without any signal brushed by left fender.
Product experience have been good too apart from the vibrations and sound from the left wing mirror vibration. Will observe if they come back after sorting out and if they does will insist for permanent solution.
Post this monsoon I will need to do a detail of the car as the lower parts have lost it's smoothness due to the road tar and some dirt/grime which doesn't go off after a normal shampoo wash.
Will keep the thread updated on the power loss issue and if this has been sorted after the fuel pump change and ECU update.
