GM factory warranties lengthen the life of vehicles from its four automobile brands: Buick, Cadillac, Chevrolet and GMC. You can also get additional coverage or extend your factory bumper-to-bumper warranty. These plans offer a variety of different coverages; however, some of them can only be added when you purchase your vehicle.
- Often transferable
- Multiple plan options
- Can directly extend factory warranty
- Limited purchase flexibility
- Unclear pricing
What is GM Warranty?
“GM Warranty” isn’t an actual company; it’s an umbrella term for offerings from General Motor’s automotive brands: Buick, Cadillac, Chevrolet and GMC. Like most automakers, these brands provide warranties for their new vehicles, but they also have additional warranty options available beyond what’s included from the factory. These protection plans are generally only available through participating dealerships, though.
GM extended warranty coverage
As a GM customer, you have several extended warranty options through your dealership, including:
- An Extended Limited Warranty
- A Platinum Protection Plan
- Gap coverage
- Pre-paid maintenance (various levels)
- Tire and wheel protection (various levels)
- Appearance Guard
- XS Wear Lease Protection
- Advanced Protection
When you purchase a new GM vehicle, you can pay more to extend your limited warranty's coverage for two years or 20,000 - 24,000 miles, depending on the make of your vehicle.
| Brand | Standard bumper-to-bumper coverage | Extended Limited Warranty coverage |
|---|---|---|
| Chevrolet | 3 years or 36,000 miles | 5 years or 60,000 miles |
| GMC | 3 years or 36,000 miles | 5 years or 60,000 miles |
| Buick | 3 years or 36,000 miles | 5 years or 60,000 miles |
| Cadillac | 4 years or 50,000 miles | 6 years or 70,000 miles |
However, you can also choose to buy a Platinum, Silver or PowerTrain protection plan at your dealership. A company called Safe-Guard Products International administers these plans. These vehicle service contracts are endorsed by GM’s brands, but they technically cover different things than your existing warranty.
GM Warranty benefits
While your GM vehicle is covered by a Powertrain Limited Warranty or a Hybrid Specific Warranty, you qualify for the company’s 24-Hour Roadside Assistance Program. This includes benefits such as:
- Emergency towing
- Lockout service
- Flat-tire changes
- Emergency fuel delivery
- Jump-starts
GM extended warranty cost
The cost of GM extended warranty coverage depends on which plan you choose. Plans range in price, but there’s not much pricing information available online besides the Platinum Protection Plan. Chevrolet, Buick, GMC and Cadillac all offer a Find My Price tool on their websites that provides quotes for a Platinum Protection Plan based on your vehicle.
As an example, we gathered quotes for a Platinum Protection Plan on a 2021 Buick Enclave in Texas and shared them below.
| Coverage term | Single-payment price* | Monthly cost* |
|---|---|---|
| 24 months / 24,000 miles | $2,227.75 | $160.42 for 14 months |
| 36 months / 36,000 miles | $2,963.05 | $143.80 for 21 months |
| 8 months / 48,000 miles | $3,502.65 | $170.85 for 21 months |
| 60 months / 60,000 miles | $3,683.15 | $179.90 for 21 months |
It’s worth noting that paying the entire amount upfront offers a 5% savings, and monthly payment plans require a down payment of roughly $99. If you’re interested in what a Platinum Protection Plan will cost for your vehicle, use the Find My Price tool on your automaker’s website to get a quote for yourself.
GM Warranty FAQ
Does GM offer an extended warranty?
Yes, GM offers various additional protection plans, including an extension of your limited warranty and vehicle service contracts. You can only extend your original warranty at the time of purchase, but you can opt for a vehicle service contract later.
What is the standard GM warranty?
At the time of publishing, all new GM vehicles come with a powertrain warranty and a shorter bumper-to-bumper warranty. Chevrolet, Buick and GMC vehicles come with 3-year/36,000-mile bumper-to-bumper warranties, but Cadillacs come with a 4-year/50,000-mile warranty.
How does a GM warranty work?
GM warranties generally work like other auto warranties:
- Depending on what type of warranty you have, GM pays for most or all of your vehicle's covered repairs at a participating dealer. However, you may have to pay a deductible with certain plans.
- Your warranty has two main limits: one in years and one in miles. Your warranty coverage ends if you meet either condition (i.e., if the amount of time has expired or you exceed the mileage limit).
There are lots of other criteria for warranty coverage and limits, so it’s worth familiarizing yourself with the details on your GM brand’s website.
What is covered in a GM bumper-to-bumper warranty?
Broadly speaking, GM's bumper-to-bumper warranties cover any repairs, including parts and labor, made to correct defects in materials or workmanship. Examine your GM contract for specific coverage details.
Still have questions?
Is a GM extended warranty worth it?
Whether a GM extended warranty is worth it depends on your vehicle, how much the warranty will cost you and the coverage it provides. Vehicles are more likely to need repairs as they age, and car repairs can be expensive. However, an extended warranty is only a value if you put it to use. Consider your budget, risk level and future financial position to see whether a GM warranty makes sense for you.

I’ve purchased 6 vehicles from GM over the course of 20 years. I influenced my mom and son to buy their cars with GM. I have always purchased the extended warranty coverage. I finally had to use the warranty and they did not honor the parameters of the warranty for trip interruption. There were no loaner vehicles, had to pay out of pocket for Enterprise (rental car agency they recommended) fees that were not reimbursed. They sent me a letter of allowances that were covered under the warranty, but did not honor even though the car broke down due to a recall that was sent out a week later.
I was sent the parameters of the reimbursement policies and submitted all required documentation. They did not pay for emergency trip interruption necessities that were communicated to during the break down time frame. I broke down 5,000 miles from home, which could have been avoided had they executed the recall notice through the GM App versus snail mail. The exact recall issue is why I was broke down in the mountains on the side of the road. I had to go to a different state just to get a rental that they did not cover the cost of, even though they told me if a loaner was not available at the dealership, they would cover the cost of a rental car. I spoke with customer service and was told that GM does not have to honor the terms and it’s at their discretion.
Keep in mind I purchased this car in August of 2024 with the a 10 year extended warranty, plus other warranty’s and at the time of breakdown it only had 22,754 miles on the odometer. It took 56 days to finally get reimbursed only to be told they were covering 53% of the rental. I was told by the representative that even though they tell you what is covered under the warranty it’s based upon their discretion and they don’t have to honor it nor give a reason.
Needless to say the $275,000 I alone purchased in vehicle’s from The General Motors franchise is not warranted a reason for the denial when all receipts have been submitted in accordance of their specific coverage parameters. I have reason to believe I am not the first nor only person this has happened to. My car was in the shop for 6 days, in which I had to wait for the repairs. That’s when the representative offered loaner, lodging and food per diem in which they did not honor. As a long time customer within the GM Family I do not feel valued and appreciated for my loyalty and will have to consider talking my business elsewhere.

This is not vehicle related but GM Warranty covers mattress protectors from Rooms To Go also. My daughter had an accident, and the mattress protector failed. They sent me out a new protector, but said in order to continue my warranty, I needed to let a company of their choice come out and clean the mattress, which I did. The company damaged my mattress by pulling strings out of it and said it was like that before they cleaned it. I had before-and-after pictures and GM Warranty sided with the company because they didn't want to be held liable. Do not get a warranty with this company under any circumstances, they are unreliable, dishonest, and cares nothing about their customers.

Do not purchase the extended warranty for your vehicle- total rip-off. We purchased a 2018 Yukon vehicle in Feb 2019, and in April 2022 we started having a small problem with one of the tires which we have returned several times and they still have not been able to fix it. We guess that it needs a new rim which we feel should be covered under our total plus warranty. I look up my service warranty - we were told I was buying a 60 kl coverage or 160,000 kl, whichever comes first. When I called the dealership on this they told me that I bought 5 year warranty that started 1.5 years after I picked my vehicle in Feb. 2019 (which I was unaware of as it was not explained to me that way). What they say they actually sold me was a 2-year warranty added to the original 3-year factory warranty which was supposed to have added up to the total 5 years.
I was told I was buying a 5-year warranty to start after the factory warranty of 1 year ran out. I thought it must be a typo on the warranty paperwork. But they say no! We have never had to use this warranty. So basically I got screwed out of $5,500 for nothing. As if any person would pay $5,500. for an extra 2 years added on the factory 3 years warranty. Please read all the fine print as I feel there was definitely misrepresentation on the part of the salesperson who sold me the extra warranty. If you ever do think of purchasing any warranty on a vehicle again please read the fine print. Just don't go by the salesperson's pitch.This will be the last GM vehicle I will ever purchase. I have owned at least 10 gm vehicles in my lifetime.

BEWARE OF THIS VEHICLE, the power train unit has leak issues according to an internal GM document and GM will charge you $3200.00 to replace it. They do not honor their own “Internal Safety Notices” which can be found online just by googling it. I have contacted GM Canada and they refuse to acknowledge the FAULT OR THE DOCUMENT (which is accessible online). They did not have a reply to why there is a “SAFETY NOTICE” on the transfer unit case for this make and model. Rather than changing the $14.99 seal where the leak occurs, they advise that GM Canada only sells the entire Transfer Unit Case – no parts are sold separately. Quite the scam. This is my second brand new XT5 I have purchased from Cadillac and will never purchase another Cadillac in my life once I am done with this one.

So we purchase a 2023 Chevy Camaro convertible 2.0 TurboTax back in November of 2023 to be shipped to Spain for our retirement. Once in Spain, we had a flat and discovered there was no flat tire kit, gas funnel in case you run out of gas and no tow hook at all. AFTER contacting customer service at GM there was no solution given by the rep who called. Totally indifference with the situation in hand. You would think she would try to solve the issue on a brand new car. Will NEVER PURCHASE A GM PRODUCT AGAIN.

I purchased my truck in March 2022. At 12500 miles my truck had to be towed to the dealer due to a knocking noise. It ended up being a major engine repair. It was assembled incorrectly in the factory. They had to place a new crank shaft bearings and rods. The repair that was done took 11 weeks due to parts. When GM made a offer of gratitude due to the trouble I went though it was like a slap in the face.
"Due to the length of time the service was delayed for over 60 days, your case qualifies for the following offers:"
The 3rd offer is either or, the first two are being offered, regardless of the 3rd choice.
"1. A Comprehensive Components Letter (CCL) which will give the customer an additional 12-month/15,000 mile past the applicable warranty.
2. 1 Year CBGC Pre-Paid Maintenance 36 months/30,000 miles. The Pre-Paid Maintenance Plus* Plans cover a number of maintenance visits based on specific time and mileage parameters, where the dealer completes a full set of recommended maintenance (as found in the owner's manual), including air filters, cabin filters, transmission and transfer fluid changes, tire rotations, and spark plugs. There is no deductible on the plan provided to you and it has been provided at no charge to you. For non-electric vehicles, this plan includes 6 multi point inspections, 6 engine oil and filter changes, 6 tire rotations, 2 cabin air filter replacements, 1 engine air replacement, 1 brake fluid replacement, and 1 windshield wiper replacement, all FREE of charge to you.
3. 1-year OnStar membership (2016 or newer models) OR 25,000 My Rewards points."
This was all they could offer. Not even after we called telling them that we bought the extended warranty and felt the first one is pretty much covered already. They came back with, "Well that's all we got." So the slap in the face is the 30000 mile warranty due to the miles on the truck = 5 oil changes. Nothing else. So I would like to warn others that if you have any issues with your truck expect to get nothing from GM to make up for them having issues with the build of their trucks. When they say, "We are going to offer you something for your trouble".... Just laugh. Because that's what they are doing when they type up this stuff on their side.

My husband and I purchased a 2021 Yukon May of 2021. We traded in the 2021 Yukon for a 2022 Yukon XL in July of 2022. When we had purchased the 2021 Yukon we purchased a Protection Plan warranty under the impression that if we were to trade in the 2021 Yukon (which we did) that the remaining balance would be refunded back to us. I went to the original dealership that we purchased the 2021 from and they told us that the warranty is not refundable nor is it transferable, that the warranty would go with the new owner of the 2021 since it is registered under that VIN. Now this is the same dealership that told us that in the event that we would trade in the 2021 we would get the balance back.
Since the dealership was being no help to us, we decided to reach out to General Motors regarding the issue that we are having. Their customer service is AWFUL. They assign you an adviser and that adviser is suppose to communicate with you within 24/48 hours with updates. Our adviser definitely lacked the communication part. I can't even begin to tell you how many hours I have spent trying to get this issue resolved. We had purchased our 2022 Yukon from a different dealership, as the other dealership had $10,000 market adjustments on their Yukons.
Our new salesman had given me the number to GM PP and they told me that there was never a warranty under our name or with that VIN. The only warranty they are now seeing is the new warranty with the new owner of our 2021 Yukon, they also told us that if the Yukon had a warranty the new owners would not be able to have a warranty as well, until that old warranty was out of our name. The dealership took our money and never added the warranty to our first Yukon. GM Customer service has been no help to us and I am very disappointed. I don't think I will ever purchase a GM vehicle again. My husband and I now have to retain an attorney to get our money back. WORST EXPERIENCE EVER!

I purchased my 2015 Cadillac Escalade with 17000 miles from a dealer in 2017. The car was originally from Canada but made in USA. I have taken it to the dealer ever since with minor issues etc. They were all covered under factory warranty. I also Purchased GM Platinum extended warranty for this vehicle. Under extended warranty I had taken the vehicle in for some issues and the claims were covered under the GM extended warranty. Now the vehicle is at the dealer since Dec 6 2021 and it needs a lot of work and GM extended warranty came up with excuse that the vehicle is Gray Market Vehicle and they can't cover my claim and that they will cancel my warranty and refund me the reimbursement. The dealer and I have gone back and forth to find any legitimate excuse but they can't seem to find any. Now I had to hire a lawyer and try to get my issue resolved.
