Powertrain Warranty Coverage: What's Covered and What Isn't
Powertrain Warranty Coverage: What’s Covered and What Isn’t
A powertrain warranty covers the parts that make your vehicle move: the engine, the transmission and the drivetrain. It pays for repairs when one of those parts fails because of a defect in materials or workmanship. It lasts longer than bumper-to-bumper coverage, but it covers far fewer systems. It also does not cover routine maintenance, wear items or damage from neglect or misuse.
This guide explains what is usually in and out, how long coverage runs, how it compares with bumper-to-bumper, and what Mopar coverage looks like for Chrysler, Dodge, Jeep and Ram owners.

TL;DR
A powertrain warranty covers the engine, transmission and drivetrain components that move the vehicle, against defects in materials or workmanship.
Most automakers offer powertrain coverage from 5 years/60,000 miles up to 10 years/100,000 miles, whichever comes first.
Bumper-to-bumper coverage is broader but shorter. Powertrain coverage is narrower but lasts longer.
Maintenance, correct fluids and fuel, and using authorized service keep your claims clean. Brake pads, clutch discs and electronics are typically not covered.
Mopar’s Ram 2026 model year powertrain extension reaches 10 years/100,000 miles, and your own warranty booklet sets the exact terms for your vehicle.

What is a powertrain, exactly?
The powertrain is the group of components that generate power and deliver it to the wheels. Think of it as a chain. The engine makes the power. The transmission manages it through the gears. The driveshafts, axles and differentials carry it to the wheels. On four-wheel-drive and all-wheel-drive vehicles, a transfer case splits power between the front and rear axles.
That chain is why a powertrain warranty is built around those systems and not around the stereo, the seats or the air conditioning. AAA describes powertrain coverage as a warranty focused on the components that move the vehicle, covering defects in their materials or workmanship.
What powertrain warranty coverage includes
Exact lists differ by manufacturer and model year, so your warranty booklet is the final word. The pattern is consistent, though. AAA lists the typical covered parts in three groups:
Engine: the engine block, cylinder heads, pistons, crankshaft and oil pump.
Transmission: the transmission housing, internal gears and the torque converter.
Drivetrain: drive axles, driveshafts and differentials, plus the transfer case on 4WD and AWD vehicles.
Automaker pages show how detailed the engine list can get. Ford’s support page names internal lubricated parts, the oil pan, cylinder block, oil pump, cylinder heads, seals and gaskets, the timing chain and related components, and the water pump as examples under its own powertrain warranty. Consumer Reports adds that major powertrain parts include turbochargers, and that on electric vehicles the motors fall under powertrain coverage while the large battery pack usually has its own separate warranty.
In plain terms, if a covered internal part fails on its own because it was built or assembled badly, the warranty is designed to pay for the part and the labor to fix it.
What a powertrain warranty usually does not cover
This is where most surprises happen. AAA states that powertrain warranties do not cover:
Electronics and comfort features
Routine maintenance such as oil changes and filters
Wear items such as brake pads and clutch discs
Damage caused by neglect, misuse or contaminated fluids
Mopar’s own warranty materials add detail for its brands. The 2022 Mopar warranty information booklet states that the Powertrain Limited Warranty does not cover costs from fire or accident, abuse, negligence or misuse (driving over curbs or overloading are given as examples), tampering with emission systems, and other listed causes. Mopar’s materials also exclude costs from poor or improper maintenance, contaminated fuels, or the use of fluids other than those the owner’s manual recommends.
A useful way to think about it: the warranty covers a part that fails on its own. It does not cover a part that wore out normally or was damaged by how the vehicle was treated.
How long powertrain coverage lasts
Powertrain coverage is the longer-lived warranty on a new vehicle. According to AAA, most automakers offer protection from 5 years/60,000 miles up to 10 years/100,000 miles. Consumer Reports says most powertrain warranties last five or six years, or 60,000 to 70,000 miles, whichever comes first. It also notes that Genesis, Hyundai, Kia and Mitsubishi stretch theirs to 10 years or 100,000 miles.
Three details change how that term works in real life:
Whichever comes first. A 5-year/60,000-mile warranty ends at the five-year mark or the 60,000-mile mark, whichever you reach first. A commuter can run out of miles years early.
The start date. Coverage does not start on the day you bring home a used vehicle. Mazda’s 2020 warranty booklet shows the typical pattern: its powertrain term of 60 months or 60,000 miles begins on the Date of First Service, and repairs are done through authorized dealers. Every brand defines its own start event, so check yours.
The term can change with the model year. Terms and exclusions are published per model year, so use the booklet for your year, not a general rule.
Powertrain vs. bumper-to-bumper
People often assume one warranty covers everything. A new vehicle normally comes with both types, and they do different jobs. AAA says bumper-to-bumper coverage lasts three years or 36,000 miles (whichever comes first) for most mainstream brands and covers nearly the entire vehicle. Powertrain coverage lasts longer but covers fewer systems.
Powertrain warranty | Bumper-to-bumper warranty | |
|---|---|---|
What it covers | Engine, transmission, drivetrain | Nearly the entire vehicle, including electronics |
Typical term | 5 years/60,000 miles up to 10 years/100,000 miles | 3 years/36,000 miles for most mainstream brands |
Best for | Protecting the most expensive mechanical parts over the long run | Early-ownership coverage of almost everything else |
Usual exclusions | Maintenance, wear items, electronics, misuse | Maintenance, wear items, damage and misuse |
The two overlap during the first years. Once bumper-to-bumper coverage ends, powertrain coverage is what remains for the major mechanical systems. For a closer look at the broader plan, read our guide on what a bumper-to-bumper warranty covers.
Mopar powertrain coverage for Chrysler, Dodge, Jeep and Ram
Mopar is the brand behind factory warranty and service for Chrysler, Dodge, Jeep and Ram vehicles. Here is what its published documents say.
Base term. The 2022 Mopar warranty information states that the Powertrain Limited Warranty lasts up to five years or 60,000 miles, whichever occurs first, counted from the start date of the Basic Limited Warranty.
What is covered. Mopar’s current model year coverage page states that for gas engines, powertrain limited coverage includes the cylinder block and all internal parts, including intake and exhaust manifolds, the oil and water pump, and the supercharger. Transmissions and drive systems (FWD, AWD, RWD and 4WD) are covered as described on that page.
The 10-year extension. Mopar’s Ram 2026 model year 10-year/100,000-mile limited powertrain warranty covers the parts and labor needed to repair a listed powertrain component that is defective in workmanship and materials. It extends the underlying 5-year/60,000-mile term up to 10 years from the in-service date or 100,000 miles, whichever comes first. The document explicitly excludes manual transmission clutch parts at any time.
If you are weighing longer protection, our page on the Mopar extended warranty walks through the options, and our Mopar overview explains what the brand offers.
How to check your own coverage
The quickest route is to start with the paperwork. Your warranty booklet lists the term, the start date and the exclusions for your model year. Ford’s support page shows how automakers handle lookups: you find vehicle-specific warranty information by logging in to your account or entering your VIN. Chrysler, Dodge, Jeep and Ram owners can review the warranty terms for their model through Mopar’s published materials, and our service team can help you read them.
Follow these steps:
Find your in-service (start) date, the day the warranty clock began, not necessarily the day you bought it.
Read the term for your model year and engine. Diesel and gas may differ.
Check the odometer against the mileage limit.
Read the exclusions list so you know what falls outside.
Call or visit the service center before you pay for a major repair, so it can be evaluated against your coverage.
Keeping your coverage in good standing
Powertrain claims usually go smoothly when the vehicle has been cared for. Mopar’s warranty materials highlight that using the correct fluids and fuel and following the owner’s maintenance recommendations is a practical condition for staying eligible for repairs. AAA likewise lists neglect, misuse and contaminated fluids as things that can affect coverage.
A short routine helps:
Follow the schedule in your owner’s manual and keep every receipt. Our maintenance schedule checklist is a good starting point.
Use the fluids the manual specifies. Transmission fluid is a common one: see our guide to the Durango transmission service interval.
Use genuine Mopar parts and recommended fluids when you service the vehicle.
Keep the engine bay tidy so leaks and seepage are easy to spot early. This guide to cleaning your engine bay covers safe steps.
Do not tamper with emission systems or overload the vehicle, both of which Mopar’s warranty information lists as exclusions.
Good records matter if you ever need to show that maintenance was done. If a major engine repair does come up outside warranty, our article on engine replacement for Chrysler, Dodge, Jeep and Ram owners explains the options.
Buying used? Check coverage before you sign
When you buy pre-owned, the question is how much factory coverage is left. A vehicle that is three or four years old may still have powertrain coverage, but it may be past the bumper-to-bumper term. The start date and mileage tell you what remains.
Certified pre-owned vehicles are one way to shop with coverage in mind. You can browse our Certified Pre-Owned vehicles, or look at certified Chrysler and Dodge models directly. Ask our team for the warranty details of the specific vehicle you like.
What we tell customers about powertrain coverage
We built our dealership around simple, honest and personal service, and warranties are where that matters most. A powertrain warranty protects the most expensive mechanical parts on the vehicle, so we think every buyer should understand it before signing, not after a repair bill.
Our advice is to treat coverage and maintenance as one plan. Know your start date, keep the service schedule and use the fluids the manual calls for. When a customer wants protection that lasts longer, we walk through Mopar’s coverage options with them and explain what each one includes and excludes.
We also help families keep their vehicles in the program they were designed for. Our service department works on Chrysler, Dodge, Jeep and Ram vehicles every day, and we are glad to read a warranty booklet with you.

FAQ
What is considered a powertrain warranty?
It is a limited warranty on the components that move the vehicle: the engine, transmission and drivetrain. It covers defects in materials or workmanship in those parts. It is not a maintenance plan and it does not cover wear items or electronics.
What does a powertrain warranty not cover?
Typically it excludes routine maintenance, wear items such as brake pads and clutch discs, electronics and comfort features. Damage from neglect, misuse, accidents or contaminated fluids is also excluded. Check your own booklet for the full list.
Is a powertrain warranty better than bumper-to-bumper?
They serve different purposes. Bumper-to-bumper covers nearly the whole vehicle for a shorter time, commonly three years or 36,000 miles. Powertrain coverage lasts longer and protects the major mechanical systems. Most new vehicles come with both.
What does Mopar powertrain warranty coverage include?
Mopar’s published terms cover the engine’s internal parts, transmissions and drive systems against defects in materials and workmanship. The base term is five years or 60,000 miles, and the Ram 2026 model year extension reaches 10 years or 100,000 miles. Manual transmission clutch parts are excluded from that extension.
How do I look up my powertrain warranty?
Start with your warranty booklet and your in-service date, then compare your mileage with the term for your model year. Manufacturers such as Ford let you look up coverage by VIN on their support sites. Our service team can also help you read your Mopar terms.
