While driving my Tata Punch, I suddenly noticed that whenever I applied the brakes and shifted to a lower gear, the smell of petrol would spread inside the cabin. What could be the reason for this? It happened when the fuel tank had little fuel left. Could that be related to the issue? Because after refuelling the tank, I could no longer notice the smell while shifting to lower gears. Please advise.

This sounds like fuel vapour entering the cabin when you slow down and downshift. When the tank is very low, fuel tends to slosh around more, which increases vapour movement inside the tank. As you lift off the throttle and brake, the vapour control system becomes more active, and if there is a weak hose, loose connection or faulty seal, those vapours can escape near the engine bay or fuel filler area. The cabin ventilation system can then pull that smell inside. Filling the tank reduces the empty space in the tank, which can explain why the smell disappeared after refuelling.Start with the simple checks. Make sure the fuel cap is tightened properly and clicks into place, and inspect the rubber seal on the cap for any cracks or damage. If the smell returns, get the car inspected soon. Ask the Tata workshop to specifically check the fuel lines for seepage, the tank vent and EVAP vapour lines, the purge valve, fuel pump seals and also for any rodent damage to smaller hoses near the firewall, which is not uncommon.If the smell is strong, keep the windows open and avoid long drives until it is checked. In many cases it turns out to be a small leak or a loose hose, but because petrol fumes are a safety concern, it is worth fixing promptly.

Hi Team Autocar, Thank you for the invaluable expert advice you provide to so many enthusiasts and buyers. I currently drive a 2017 Renault Duster 110PS AMT Diesel and am now considering purchasing a used petrol automatic SUV that is around three years old. My priorities are decent fuel efficiency, low running and maintenance costs, and overall reliability. My monthly city driving is approximately 1,000-1,200 km. Please note that I am not considering vehicles from Maruti, Mahindra, or Tata. Could you please recommend the most suitable options for my requirements and budget? Regards, Karan

With mostly city use at 1,000-1,200 km a month and a focus on mileage and low upkeep, a three-year-old Toyota Urban Cruiser Hyryder hybrid automatic suits you best. In slow city traffic, it often runs on electric power, so fuel use is far lower than that of a regular petrol car, and the automatic transmission is very smooth and quiet. Coming from your Duster diesel AMT, you will notice easier stop-go driving, lower vibration, and Toyota’s simple, predictable service experience.Do note a couple of trade-offs. The hybrid’s boot is smaller than some rivals, and it doesn’t feel very strong if you push hard on the highway. Clean used examples can also cost more than a regular petrol.If the hybrid price stretches the budget, look for a Hyundai Creta petrol automatic from the same period. It is easy to drive, comfortable over bad roads, and has wide, affordable service support.Another sensible pick is the Honda Elevate automatic for its simple ownership and light steering. For your brief, the Hyryder hybrid lines up best, with the Creta or Elevate as safer-value backups.
