The monsoon is winding down across most of India, and your car has quietly absorbed three months of abuse. Waterlogged roads, hidden potholes, mud in places mud should not reach. September is the month to undo that damage, partly because the weather allows it and partly because service centres go from empty to impossible once the festive rush begins. Here are the eight jobs, in order of how expensive they get if ignored.
1. Underbody wash and inspection
Everything the monsoon threw at the road ended up under your car. Mud traps moisture against metal, and moisture plus metal plus time equals rust. A pressure underbody wash costs a few hundred rupees. Rust repair on a floor pan costs a few thousand and a weekend. Ask the washer to point out any surface rust already forming so you can get anti-rust treatment on it early.
2. Brakes, before anything else mechanical
Months of driving through water wears pads faster and can leave discs with surface corrosion. The signs are a soft pedal, a grinding note, or the car pulling to one side under braking. Any of those means a brake inspection this week, not after Diwali.
3 to 8: The rest of the checklist
| Job | Why now | Rough cost |
|---|---|---|
| Tyre check and rotation | Pothole season causes sidewall bulges and uneven wear | Free to Rs 500 |
| Wiper blade replacement | Three months of heavy duty leaves them streaking | Rs 400 to 1,200 |
| AC filter and drain check | Damp cabins grow that famous monsoon smell | Rs 300 to 800 |
| Battery terminals | Humidity corrodes terminals, festive traffic punishes weak batteries | Cleaning is free |
| Headlight and fog lamp check | Moisture inside lenses dims output | Varies |
| Interior deep clean | Wet-shoe carpets breed mould under the mats | Rs 1,500 to 3,000 |
The smell test people ignore
If your cabin smells musty with the AC on, do not just hang a stronger air freshener. That smell is mould in the evaporator or under the carpets, and it worsens until treated. An AC disinfectant treatment plus drying out the floor mats in the sun for a day usually kills it. Your passengers will notice the difference before they notice your new seat covers.
Why September specifically
Two reasons. Service centres are quiet right now and slots are easy. From October, festive deliveries and pre-Diwali servicing jam every workshop in the country. And if you are planning to sell or exchange your car during the festive buying wave, a freshly serviced, rust-free, nice-smelling car negotiates from a stronger position.

FAQ: post-monsoon car care
How much does a full post-monsoon checkup cost?
Bundled with a regular service, the additions above typically run Rs 2,000 to 5,000 depending on what needs replacing. Rust repair is the wildcard, which is exactly why you catch it early.
My car was in waterlogging once. Anything special to check?
Yes. Get the engine oil checked for a milky tint, test all electricals, and have the mechanic inspect wiring connectors under the carpets. Water damage shows up weeks late.
Do EVs need post-monsoon care too?
Yes, the same underbody, brake, tyre and cabin checks apply. Battery packs are sealed and tested for water, so no special worry there. Charging port pins deserve a look for moisture or corrosion.
Can I do any of this myself?
Wipers, battery terminal cleaning, mat drying and the visual tyre check, absolutely. Brakes and underbody belong to people with a lift and experience.
