What Car Has the Best Warranty? Longest Factory Coverage Compared

What Car Has the Best Warranty?

If you are buying a new car and want the longest factory warranty, Hyundai, Kia, Mitsubishi and Genesis are among the strongest choices in the U.S. market. Several offer 10-year/100,000-mile powertrain coverage for qualifying original owners, along with longer basic warranties than many competing brands.

But the longest warranty is not automatically the best warranty. A 10-year powertrain warranty usually covers only specific engine, transmission and drivetrain components. The broader bumper-to-bumper or new-vehicle warranty may end much sooner, and the full 10-year protection may disappear when the vehicle is sold to a second owner.

This guide compares the major factory warranty terms, explains the catches behind 10-year warranties, covers EV battery warranties, and shows what used-car buyers should verify before assuming a vehicle is still fully covered.

Quick Answer: Which Car Has the Best Warranty?

For traditional gas vehicles in the United States, Hyundai, Kia, Mitsubishi and Genesis offer some of the longest advertised factory powertrain warranties.

For qualifying original owners, these brands generally advertise powertrain protection reaching 10 years or 100,000 miles.

Best overall starting point: Hyundai, Kia, Mitsubishi and Genesis all deserve consideration if warranty length is a major buying priority. But compare the 5-year/60,000-mile basic coverage, transfer rules, roadside benefits, EV coverage and exclusions—not just the headline 10-year number.

Best Car Warranties Compared

Brand Basic/New Vehicle Warranty Powertrain Warranty Roadside Assistance Major Catch
Hyundai 5 years / 60,000 miles 10 years / 100,000 miles for original owner 5 years / unlimited miles Subsequent-owner powertrain coverage generally falls to 5/60
Kia 5 years / 60,000 miles 10 years / 100,000 miles for original purchaser and eligible Kia CPO purchasers 5 years / 60,000 miles Full 10/100 powertrain coverage does not automatically follow every ordinary used Kia
Mitsubishi 5 years / 60,000 miles 10 years / 100,000 miles for original owner 5 years / unlimited miles 10/100 powertrain coverage is generally not transferable
Genesis 5 years / 60,000 miles 10 years / 100,000 miles for qualifying original owner on gas vehicles 5 years / unlimited miles Full powertrain coverage has ownership limitations
Tesla 4 years / 50,000 miles Battery/drive unit coverage varies by model Separate terms apply Battery mileage varies by model and version

Warranty numbers are not interchangeable. A 10-year powertrain warranty is much narrower than a 5-year bumper-to-bumper warranty.

What Does “Best Warranty” Actually Mean?

Drivers often search for the longest warranty, but there are several different types of factory protection.

A Strong Warranty Package Should Be Judged By

  • Length of the basic or bumper-to-bumper warranty
  • Length of powertrain protection
  • What engine and transmission components are actually covered
  • Whether coverage transfers to later owners
  • EV or hybrid battery coverage
  • Roadside assistance duration
  • Rust or anti-perforation protection
  • Deductibles, exclusions and maintenance requirements
  • Certified pre-owned warranty benefits

The best warranty is the one that protects the expensive failure you actually experience. A long warranty is less valuable if the failed component is excluded.

Hyundai Warranty

Hyundai continues to offer one of the strongest new-car warranty packages in the United States.

Key Hyundai Coverage

  • 10-year/100,000-mile Powertrain Limited Warranty for qualifying original owners
  • 5-year/60,000-mile New Vehicle Limited Warranty
  • 7-year/unlimited-mile Anti-Perforation Warranty
  • 5-year/unlimited-mile Roadside Assistance

The important detail is ownership.

Hyundai states that the 10-year/100,000-mile powertrain protection applies to the original owner. When the vehicle is sold, subsequent owners generally receive powertrain coverage under the remaining 5-year/60,000-mile New Vehicle Limited Warranty rather than the full 10/100 benefit.

Used Hyundai warning: Do not assume a six-year-old Hyundai with 70,000 miles still has the famous 10-year/100,000-mile powertrain warranty simply because the first owner did.

Kia Warranty

Kia also advertises an industry-leading 10-year/100,000-mile Powertrain Limited Warranty.

Key Kia Coverage

  • 10-year/100,000-mile Powertrain Limited Warranty
  • 5-year/60,000-mile New Vehicle Limited Warranty
  • 5-year/100,000-mile Limited Anti-Perforation Warranty
  • 5-year/60,000-mile Roadside Assistance
  • 10-year/100,000-mile EV system and battery coverage on qualifying EVs

Kia specifically states that its full 10-year/100,000-mile powertrain protection applies to the original purchaser and qualifying purchasers of Kia Certified Pre-Owned vehicles.

That is why used-car shoppers should read KIA Warranty: 10 Years or 100,000 Miles? What’s the Catch?.

If you are specifically buying used, also read Used Kia Warranty Trap: Does 10-Year Coverage Transfer?.

Kia's warranty is excellent for qualifying buyers, but “10 years/100,000 miles” should never be treated as automatic coverage for every used Kia on the market.

Mitsubishi Warranty

Mitsubishi also competes aggressively on warranty coverage.

Key Mitsubishi Coverage

  • 10-year/100,000-mile Powertrain Limited Warranty for the original owner
  • 5-year/60,000-mile New Vehicle Limited Warranty
  • 5-year/unlimited-mile Roadside Assistance
  • Limited complimentary maintenance on qualifying newer vehicles

Mitsubishi states that the 10-year/100,000-mile powertrain coverage applies to the original owner. Subsequent owners generally receive the remaining balance of the 5-year/60,000-mile new-vehicle warranty.

Mitsubishi's 10/100 coverage has the same important buying lesson: headline warranty length and transferable warranty length are not necessarily the same thing.

Genesis Warranty

Genesis combines a longer warranty with luxury-car ownership benefits.

Key Genesis Coverage

  • 5-year/60,000-mile New Vehicle Limited Warranty
  • 10-year/100,000-mile Powertrain Limited Warranty for qualifying original owners of gas vehicles
  • 10-year/100,000-mile EV battery warranty on qualifying electric models
  • 5-year/unlimited-mile Roadside Assistance
  • 3-year/36,000-mile complimentary scheduled maintenance on qualifying new vehicles

The complimentary maintenance makes Genesis particularly interesting because warranty length and ownership benefits are not exactly the same thing.

Luxury buyer tip: When comparing Genesis with another premium brand, compare complimentary maintenance, roadside assistance and warranty length together—not only the sticker price.

Tesla Warranty

Tesla approaches warranty coverage differently because the battery and drive unit are among the most expensive components owners worry about.

Tesla Basic Vehicle Coverage

Tesla currently provides a 4-year/50,000-mile Basic Vehicle Limited Warranty in the United States.

Tesla Battery and Drive Unit Coverage

Battery and drive-unit coverage varies by model and configuration.

Tesla Vehicle Battery & Drive Unit Coverage
Model S / Model X / Cybertruck 8 years / 150,000 miles
Certain Model 3 and Model Y versions 8 years / 100,000 miles
Certain higher-range/performance Model 3 and Model Y versions 8 years / 120,000 miles

Tesla also specifies minimum battery-capacity retention terms for covered vehicles.

For a dedicated battery discussion, see Tesla Battery Warranty: When Replacement Is Covered.

What About Toyota, Honda, Ford and Chevrolet?

Many major manufacturers use a more traditional factory warranty structure.

A common pattern among large mainstream brands is:

  • 3-year/36,000-mile basic warranty
  • 5-year/60,000-mile powertrain warranty

Exact coverage varies by manufacturer, model and powertrain, particularly for hybrids and EVs.

This is why Hyundai, Kia, Mitsubishi and Genesis stand out: their 5/60 basic coverage and potential 10/100 powertrain coverage are substantially longer than the traditional 3/36 and 5/60 structure offered by many competitors.

Bumper-to-Bumper vs Powertrain Warranty

This is probably the most important warranty distinction for shoppers.

Warranty Type Typically Covers Usually Does Not Mean
Basic / New Vehicle / Bumper-to-Bumper Many vehicle systems and factory defects Every maintenance or wear item
Powertrain Specified engine, transmission and drivetrain components Entire vehicle for 10 years
EV Battery Specified high-voltage battery defects and sometimes capacity retention Every electrical component
Anti-Perforation Specified rust-through conditions Every cosmetic rust spot
Roadside Assistance Towing or emergency roadside services within plan rules Repair costs themselves

“10-year warranty” does not mean the whole car is covered for 10 years. In many cases, the broader factory warranty ends at 5 years/60,000 miles and the longer coverage applies only to specified powertrain components.

The Catch With a 10-Year/100,000-Mile Warranty

A 10-year warranty sounds simple until you read the warranty manual.

Common Limitations Include

  • Original-owner restrictions
  • Specific covered powertrain components only
  • Whichever occurs first: years or mileage
  • Commercial-use exclusions
  • Maintenance responsibilities
  • Normal wear exclusions
  • Damage caused by modifications or outside events
  • Different terms for replacement parts

This is why a car advertised with a 10-year warranty can still generate an expensive repair bill before ten years have passed.

Do Car Warranties Transfer to a Second Owner?

Some do. Some transfer only partially. Some long powertrain benefits do not transfer at all.

Brand 10-Year Powertrain Transfer Situation
Hyundai Original-owner 10/100 generally becomes 5/60 powertrain coverage for subsequent owners
Kia Full 10/100 applies to original purchaser and qualifying Kia CPO purchasers
Mitsubishi 10/100 generally applies to original owner; later owners receive remaining 5/60 coverage
Genesis Original-owner restrictions apply to 10/100 powertrain coverage

Used-car rule: Never ask only, “Does this model have a 10-year warranty?” Ask, “What warranty remains for me, as the next owner, on this exact VIN?”

Can Certified Pre-Owned Cars Keep Longer Coverage?

Yes. Certified Pre-Owned programs can change the warranty equation considerably.

For example, Kia states that qualifying Kia Certified Pre-Owned buyers can receive the 10-year/100,000-mile powertrain warranty. Hyundai also offers specific Certified Used Vehicle powertrain protection reaching 10 years/100,000 miles from the original in-service date under applicable program terms.

Genesis Certified vehicles can also include extended limited warranty coverage and remaining powertrain protection under program rules.

CPO can be valuable when buying a brand whose longest original-owner warranty normally does not transfer fully. Compare the CPO premium with the extra warranty protection before deciding.

Which Cars Have the Best EV Battery Warranty?

EV warranties need their own comparison because federal emissions and battery rules, manufacturer coverage and capacity-retention guarantees differ from conventional powertrain warranties.

Examples

  • Kia offers 10-year/100,000-mile EV battery coverage on qualifying vehicles.
  • Hyundai offers 10-year/100,000-mile hybrid/electric battery protection on qualifying vehicles.
  • Genesis offers 10-year/100,000-mile EV battery coverage on qualifying electric vehicles.
  • Tesla offers 8-year battery and drive-unit warranties with mileage ranging by model and configuration.

EV shoppers should check capacity retention, not only total failure coverage. A battery warranty may specify a minimum remaining capacity threshold before degradation becomes warrantable.

What Car Warranties Usually Do Not Cover

A factory warranty is not prepaid maintenance and does not insure the vehicle against every expense.

Common Exclusions or Limited Items Include

  • Brake pads
  • Tires
  • Wiper blades
  • Routine oil changes
  • Filters
  • Normal clutch wear
  • Accident damage
  • Theft damage
  • Abuse or racing
  • Unauthorized modifications that cause damage
  • Damage from neglected maintenance
  • Normal deterioration

Warranty does not mean “free repairs for ten years.” It means the manufacturer agrees to repair specified defects under specified conditions.

Can Missing Maintenance Void Your Warranty?

Manufacturers can require owners to maintain the vehicle properly, but warranty disputes are more nuanced than “you missed one dealer oil change, so the entire warranty is gone.”

Keep records showing:

  • Oil changes
  • Required fluid services
  • Filters
  • Scheduled inspections
  • Repair invoices
  • Recall work
  • Parts receipts for DIY maintenance

You generally do not need to use the dealership for every routine maintenance service just to preserve a factory warranty. What matters is performing required maintenance correctly and documenting it.

Do You Need an Extended Warranty?

A strong factory warranty may reduce the need to buy an extended warranty immediately.

If you already have 5-year/60,000-mile basic coverage and long powertrain protection, buying overlapping coverage on day one may provide little immediate benefit.

How to Check Warranty Before Buying a Used Car

Step 1: Get the VIN

Do not rely on the seller's description alone.

Step 2: Find the Original In-Service Date

Warranty time generally begins when the vehicle was first delivered or placed in service, not when you buy it used.

Step 3: Ask the Manufacturer or Dealer

Request the remaining factory warranty status for the VIN.

Step 4: Verify Whether You Qualify as a Subsequent Owner

The longest advertised powertrain benefit may be restricted to the original purchaser.

Step 5: Check CPO Status

A genuine manufacturer-backed Certified Pre-Owned vehicle may receive different warranty benefits.

Step 6: Ask About Recall and Special Coverage

Recall remedies and manufacturer warranty extensions can exist separately from the standard warranty.

Step 7: Get the Warranty Terms in Writing

Do not buy based on “the salesman said it's still under warranty.”

Best Warranty by Type of Buyer

Buyer Warranty Feature to Prioritize
Keeps cars 8–10 years Long original-owner powertrain warranty
Trades every 3 years Strong basic coverage and complimentary maintenance
Buying used Transferable coverage or strong CPO warranty
Buying an EV Battery/drive-unit coverage and capacity guarantee
High-mileage driver Mileage limits matter more than years
Luxury buyer Basic warranty plus maintenance and roadside benefits

A 10-year warranty is most valuable to someone who actually keeps the vehicle long enough to use it. A driver who trades every three years may benefit more from strong bumper-to-bumper coverage and complimentary maintenance.

Official Warranty Resources

Bottom Line

Hyundai, Kia, Mitsubishi and Genesis currently offer some of the longest factory powertrain warranties in the U.S., reaching 10 years or 100,000 miles for qualifying buyers.

But the headline number does not tell the whole story. The broader new-vehicle warranty generally expires sooner, powertrain coverage applies only to specified components, and original-owner restrictions can dramatically reduce the warranty value when a vehicle is sold used.

Best buying rule: Compare basic coverage, powertrain coverage, transferability, roadside assistance and EV battery terms together. If buying used, verify the remaining warranty for the exact VIN before paying extra because a seller advertises a “10-year warranty.”

Frequently Asked Questions FAQ’s

What car brand has the best and longest warranty?

Hyundai, Kia, Mitsubishi and Genesis offer some of the longest factory powertrain coverage in the United States, with qualifying coverage reaching 10 years or 100,000 miles. The best choice depends on transfer rules, basic warranty length and the type of vehicle you are buying.

Which car has a 100,000-mile warranty?

Hyundai, Kia, Mitsubishi and Genesis offer 10-year/100,000-mile powertrain coverage for qualifying buyers. Some EV manufacturers also offer battery or drive-unit warranties reaching or exceeding 100,000 miles.

What vehicle has a 10-year warranty?

Many new Hyundai, Kia, Mitsubishi and Genesis vehicles include qualifying 10-year/100,000-mile powertrain coverage. This does not mean every part of the vehicle is covered for ten years.

Does a 10-year car warranty transfer to the second owner?

Often not in full. Hyundai, Mitsubishi and Genesis place original-owner limitations on their longest powertrain coverage, while Kia provides full 10/100 powertrain coverage to the original purchaser and qualifying Kia Certified Pre-Owned purchasers. Always verify the VIN-specific warranty before buying used.

Does Kia's 10-year warranty transfer?

Not automatically to every ordinary used-car buyer. Kia states that its 10-year/100,000-mile Powertrain Limited Warranty applies to the original purchaser and qualifying Kia Certified Pre-Owned purchasers.

How long is Hyundai's warranty for a second owner?

Hyundai states that when a vehicle is sold while still within the 10-year/100,000-mile original-owner powertrain period, subsequent-owner powertrain coverage is reduced to 5 years or 60,000 miles from the original in-service date.

How long is Tesla's warranty?

Tesla's U.S. Basic Vehicle Limited Warranty is 4 years or 50,000 miles. Battery and Drive Unit Limited Warranty coverage lasts 8 years, with mileage limits that vary by model and configuration.

Is bumper-to-bumper warranty better than powertrain warranty?

Bumper-to-bumper or basic coverage is broader because it generally covers many more vehicle systems. Powertrain coverage lasts longer on some brands but is limited mainly to specified engine, transmission and drivetrain components.

Does a warranty cover normal maintenance?

Usually no. Oil changes, filters, brake pads, tires and other routine maintenance or wear items are generally separate unless the manufacturer specifically includes complimentary maintenance.

Should I buy an extended warranty if my car already has a 10-year warranty?

Not automatically. Determine what your factory warranty already covers, when the broader basic warranty expires, which repairs worry you most and whether an extended plan would overlap coverage you already have.

What should I check before buying a used car advertised with a factory warranty?

Check the VIN, original in-service date, remaining basic coverage, powertrain transfer rules, recall status, Certified Pre-Owned status and any manufacturer warranty extensions. Get the remaining warranty confirmed in writing.
