Hello!
I am owner of a Fiat Tipo, 1,6 cc (4 doors) since the last 5 months.
To my surprise, in the place of the spare (inside of the trunk) I have found today more than 2 Lt of water.
Before 2 days I cleaned the car external with water. Also the roads were very humid during the last week.
But I can not understand, what the reason of this imcidence can be.
Have you ever faced the same problem with this car?
Thank you in advance.
George

Check that the rear lights are seated correctly and fixed. There are also some air extraction vents that should be one way flow that need to be checked, possibly behind the bumper.

Look from underneath and see if there are any missing sealing grommets.

Also check the roof lining is dry. Bravos had a problem with badly sealed roof panels letting in water. Have you been in any flooded areas.

You may also like to check the damper top mounting points are not responsible for allowing water in.

Check the tailgate rubber is also properly seated all the way round the door.

Good luck.
