A three-month car warranty typically only covers the major drivetrain of a vehicle. This includes the components of the vehicle that deliver power to the wheels, such as the engine, transmission and rear end, according to Car Clicks.
Three-month car warranties are usually only applicable to sales of pre-owned vehicles, reports Popular Mechanics. As such, they are unlike warranties that apply to newly purchased vehicles. They usually have limited coverage and often include a deductible, according to ERATE. Three-month car warranties often include the stipulation that the vehicle is covered for the duration of either 90 days or 3,000 miles, whichever comes first. Though the three-month car warranty is the most common extended warranty associated with pre-owned vehicle purchases, there are often a wide range of extended warranties available .
Other pre-owned vehicle warranty options include six-month/6,000-mile or 12-month/12,000-mile warranties that can cover a range of issues from powertrain to electrical to braking systems, as reported by Car Clicks. When considering an extended warranty for a pre-owned vehicle, Popular Mechanics suggests that buyers first look into purchasing a certified pre-owned vehicle and pay attention to the deductible, time frame and coverage of the warranty that accompanies the purchase. In the case that a certified pre-owned car is not an option, the same careful consideration should apply to the aftermarket warranty. In many cases, the price of the warranty and the specific terms of the plan are negotiable.
