You took your car to Hyundai and they said that timing belt is dry rotted it needs be changed you only have 33 000 miles on Is possible?

While cars generally don't have service intervals for timing belt replacements at such a low mileage, timing belts can occasionally dry rot prematurely due to a number of factors including extreme heat, contact with automotive chemicals, or age.

It's possible for a car to have a timing belt that has dry rot at only 33,000 miles. However, it is relatively uncommon. The timing belt is a critical component of an internal combustion engine and is responsible for synchronizing the movement of the pistons and valves. If the timing belt fails, it can cause serious damage to the engine.

Several factors could cause a timing belt to dry rot prematurely. These include:

1) Environmental conditions. Timing belts are made of rubber, which is susceptible to deterioration from heat, ozone, and other environmental factors.

2) Chemical exposure. Timing belts can also be damaged by exposure to automotive chemicals, such as oil and grease.

3) Manufacturing defects. In some cases, timing belts may have manufacturing defects that make them more susceptible to dry rot.

It's important to note that the timing belt is a critical safety component and should be inspected and replaced according to the manufacturer's recommendations. If you are experiencing any issues with your car's timing belt, it's important to have it inspected by a qualified mechanic.
