My understanding is that warranty is retained only if we make changes through dealership. If this has been discussed elsewhere, please let me know.
This is indeed a very relevant question - "
...to tweak or not to tweak: that is the question..."
To understand the situation, this is what the actual warranty might say, "...the dealer will repair or replace any part which proves to be defective within the limits of warranty at no charges to the customer for parts and labor..." or something along these lines.
The right answer, in my opinion, is to stay with original components until warranty period is over (2 year standard or 4 year extended) and then do whatever you seem fit.
And the important thing is to follow service intervals recommended by the manufacturer during warranty period. This is an example of what may happen if you don't, (a real life story involving a Toyota small car). A friend, who does not use the car much, after the first dealer service, did bother not send in car for the second service because he thought it had not put on enough mileage. But he did however, change the engine oil himself at home, using the same brand and type that the dealer uses. About six months later, when he took the car in for service, he was told that one of the cylinder block had loss of compression (chipped piston ring, perhaps?). He was asked to pay for the repairs because, one, he had not brought it in for the scheduled second service (where it may have been detected), and two, because he had changed the engine oil himself. From any point of view this is clearly a 'manufacturing defect' that could not have been cause by mere engine oil change by the owner. Had he changed brake fluid at home and not the engine oil (assuming he is mechanically adept), the warranty would have probably covered the repairs. It was not covered because the owner failed to read the warranty / owners manual and engine oil has everything to do with the engine and its components. The dealer probably knows that it is a manufacturing defect, but preferred to throw the book at the owner.
However, certain things (especially those not mentioned in the Owner's Manual) will not void the warranty terms - cosmetic items like fitting door handle covers, a grill badge, window films. paint treatment, seat covers, etc. Certain items can be easily removed before the car is sent for its scheduled service within warranty period, example, a GPS tracking system installed in the car's diagnostic port (remember the diagnostic port is meant for the service guys not the owner - debatable), or Pete's Tuning Box (for BHP/torque enhancement diesel cars) which can be removed in 10 minutes, K&N air filters, etc.
In replacing any component during warranty period, one has use some common sense. Eg:
- OEM headlights are dull, replace them with bighter (30% more) H4s like Osram Nightbreaker Plus (which are same as OEM 55/60 wattage rating).
- Want to replace those 175 skinny bicycle tyres, arm your self with the knowledge of OEM tyre fitted in other markets and go for what is the widest on offer, you could get away with it (yes, you will be surprised at what you find, and good that Honda does not follow identical fittment on global scale, Indians can do all right on skinny tyres).

- Walk into the best dealership in your city and see what the dealer himself has on offer as "optional" when you pretend to be buying a car. You will be surprised to see so many items (like ICE, Head units, spoilers, alloy wheels, etc) that are not even mentioned in the them manufacturer's list of options.
Food for thought: If you drive in with wider wheels/tyres (say, within OEM limits), and if you seat belt tension spring is broken and does not work, can they refuse to cover the repair when the car is under warranty? I don't think so.
Add this to your Honda India data-base:
- 72,115 Honda City cars recalled for defective power window switches.
- 11,381 Honda Accord, CR-V recalled for faulty airbags.
- 1,225 Honda Amaze recalled for faulty airbags.
- 31,226 Honda Amaze and Brio recalled for faulty brake valve in non-ABS systems.
- 57,800 Honda City recalled due to faulty rocker arm springs in the engine.
So, it not a problem free car manufacturer, but they are a decent company to deal with. However, if you are not ready to play mind games with the dealer, do you mods after the warranty period is over.
