Faults:

My timing belt wore out at 45000 kms.

Timing bearing broke and ceased at 45000 kms.

A/c switch stops working at 46000 kms.

Front axil makes noise on sharp right curves at 20000 kms.

General Comments:

The car is excellent in handling and road grip.

Siena has a fast initial pickup but is a bit sluggish in 3rd gear.

Compared to 1.2 engine size top speed is excellent at 160+

A/c is excellent, but not in scorching sun.

Seating is extremely comfortable specially front buckets.

The music system is classic, complete with 6 speakers.

Fog lamps are very effective.

Cupholder in glove box is a well thought advantage.

Lot of space in glove box, door panels & dashboard.

Mileage is huge--18 km/litre is what I have clocked, worst is 12 with a/c and 5 persons on board, city road.

Faults:

This car having excelent performance.Its something like a tank. The poor service done by the dealer is the head ache. In 65000 the vehicle is not moving in the third gear. It was very expensive as I have to change the full set of third gear. It took 4 months to get it repaired from TVS service centre. They are very irresponsible people I saw in my life. Low mileage.A leakage from the Turbo side started recently.

General Comments:

The vehicle is very good for long drive. The low turning radius makes it difficult in city parking.

Faults:

A/C Switch faulty replaced under warranty

Gear Box not moving on Third gear parts replaced under warranty 55000 km

Same problem again 70000km spares given on reduced price only.

A/C not effective when its above 35 c temp.

A/C Evaporator unit and Discharge tube changed 85000 km.

Timing belt changed 88000 km - Seems it can still do a lot more than that..was changed fearing it may break down and cause damage.

General Comments:
