Just bought the 2012 GL Elantra and I really love this car. But unknown to a lot of people who shared their excellent reviews is what lurks underneath the car. I discovered recently that some part of the chassis behind the tires have coating and some don't have any as you can see the painted metal part. SISSLEY DEALERSHIP called it gravel and sand protection and to my surprise not an undercoating to protect the cars chassis. Hyundai headoffice already gave them the GO signal to have it done but they did not bec of the following reasons:
1. They checked the Elantras in their dealership and have the same thing
2. Undercoating might affect the ABS & brake lining
Check your Elantras
Corrosion resistance in cars has changed drastically over the last 20+ years.
The steels they use are more resistant and the coatings much more advanced than they used to be.
I wouldn't jump to conclusions about what is good/bad based upon where they sprayed undercoating.
It can sometimes trap moisture applied incorrectly so like any tool... it has it's use in some places and is better left off in others.
