I think they give warranty, from third party warranty companies; AAB is also giving extended warranty from similar companies. Be sure to read their clauses and terms & conditions properly and it is covered in Qatar, there is no harm in calling the warranty company directly and ask for specific details before you jump, like were should be the services be done during the warranty period, what all are covered, etc
The normal service you can do it in any Teyseer or AC Delco centers.
