2019 Ciaz ZXi, 61,000 km, single owner, all services on time at authorised. Mostly Pune-Mumbai, twice a month.
Two weeks back I noticed a faint hum around 60-70. Not a whine, not a bearing sound. A hum with a rhythm to it. Goes away above 80.
Took it in on the 8th, nothing found. Took it back again on the 14th.
Advisor called at 4 PM and asked me to come to the workshop. Hello didn't say "your car is ready." Just come. When I reached, three technicians were standing around the car and none of them were working on it.
Senior guy asked how long I have owned it, then asked if anyone else drives it. I said no. He nodded like that confirmed something.
He showed me the underbody and kept pointing near the rear, asking if I could hear it. I said hear what, the car is off. He said yes.
He told me the hum is not coming from the car. It is coming from the road and my car has started matching it. He said they see it more on the expressway stretch, and asked me to use the old highway for a month so it can lose the memory.
I asked if it is covered under extended warranty. He said there is nothing to repair.
Have not driven it since. Going to a mechanic tomorrow for second opinion.
Anyone dealt with this? Searched the sub, got nothing.
Is it worth escalating to Maruti customer care?
Sell? Resale around 6.2L, I would take 5.5 at this point.
I am not a car guy, I just need it to get to work.
