2022 Subaru Ascent Corrosion Protection

Corrosion protection

Your SUBARU has been designed and built to resist corrosion. Special materials and protective finishes have been used on most parts of the vehicle to help maintain a fine appearance, strength, and reliable operation.

Most common causes of corrosion

The most common causes of corrosion are:

• The accumulation of moisture-retaining dirt and debris in body panel sections, cavities, and other areas.
• Damage to paint and other protective coatings caused by gravel and stone chips or minor accidents.
  Corrosion is accelerated on the vehicle when:
• It is exposed to road salt or dust control chemicals or used in coastal areas where there is more salt in the air, or in areas where there is considerable industrial pollution.
• It is driven in areas of high humidity, especially when temperatures range just above freezing.
• Dampness in certain parts of the vehicle remains for a long time, even though other parts of the vehicle may be dry.
• High temperatures will cause corrosion to parts of the vehicle that cannot dry quickly due to lack of proper ventilation.

To help prevent corrosion

Wash the vehicle regularly to prevent corrosion of the body and suspension components. Also, wash the vehicle promptly after driving on any of the following surfaces.

• Roads that have been salted to prevent them from freezing in winter
• Mud, sand, or gravel
• Coastal roads

After the winter has ended, it is recommended that the underbody be given a very thorough washing.
Before the beginning of winter, check the condition of underbody components, such as the exhaust system, fuel and brake lines, brake cables, suspension, steering system, floor pan, and fenders. If any of them are found to be rusted, they should be given an appropriate rust prevention treatment or should be replaced. Contact your SUBARU dealer to perform this kind of maintenance and treatment if you need assistance.
Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water and dirt accumulation under the floor mats because that could cause corrosion. Occasionally check under the mats to make sure the area is dry.
Keep your garage dry. Do not park your vehicle in a damp, poorly ventilated garage. In such a garage, corrosion can be caused by dampness. If you wash the vehicle in the garage or put the vehicle into the garage when wet or covered with snow, that can cause dampness.
If your vehicle is operated in cold weather and/or in areas where road salts and other corrosive materials are used, the door hinges and locks, rear gate lock, and hood latch should be inspected and lubricated periodically.
