  • I purchace a vehicle from Hillbish Ford 4 months ago and the transmission went bad on Saturday June 9, 2012. We took it to the dealer and they said that the transmission was bad and that they needed to replace it. I bought warranty and was told that if anything goes wrong with the vehicle, I would only have to pay $100.00. it's also in the contract. My warranty also states that I conld get a renter during the time of the repair. It's Tuesday and I told that they will pay$250.00 and i have to pay the $350.00. I do not have it and I need my truck. My wife is sick and I have to get her up so she can carry me to work, and return to pick me up. I'm thinking about seekiong an attorney, because they broke the warranty contract.
  • How can I find online the criteria by which dealers make decisions about extended warranties?

    Not at all surprised to see the article mention Honda as a manufacturer who refused repairs under warranty. Has a 2010 Accord V6 with a manual transmission which over 2 years was broken down for over 8 months because of engine defects. Honda would not honor the warranty claiming that the manual transmission made the driver exclusively responsible for engine defects.
  • Your article states to follow the manufacturer's service schedule. The problem I'm having is the schedule says one thing and the service manager and salesmen say another. For example, the manual says to add a detergent at 7500 miles. The serv. manager said add it at 15000 miles. Will the manufacturer be able to tell? Doubtful. The manual says do an oil change at 3750 miles. I was told by someone at the dealership 5000 is fine. THIS the manufacturer will be able to tell. Finally, I met with the sales manager due to issues I had at the dealership. HE said he does regular maintenance (we live where I believe most of my driving is on hills/and city driving - not severe) on his car not using the severe maintenance as his guide. The service manager said it's severe (I disagreed). He also said I had to go to the dealership for an oil change and the sales manager said I don't have to (I know) and the serv. manager was just trying to bring in work.

    It's nuts.
  • I bought a Certified Pre-Owned (CPO) 2013 Hyundai Sonata on Saturday a week ago. With a CPO Hyundai, you get the balance of both the 5 year new car warranty, and the 10 year/100,000 mile powertrain warranty. That balance is calculated from the original owner's delivery date and odometer mile zero. I was sold and additional third party warranty through Zurich Insurance, which extended the bumper to bumper coverage out to 7 years with no deductible. It cost me and additional $15 a month. On the following day (a Sunday) I researched the third party warranty company, and found nothing but negative remarks, and the lowest ranking a company can get from the Consumer Affairs website. On Monday I go in and cancel the third party extended warranty, and they told me my monthly payment was exactly what I was quoted for the car with the factory warranty. I went in the next day to get something fixed that cropped up on the test drive, and I am told that when I cancelled the third party warranty, it cancelled my factory warranty as well. Is that even legal?

    Are you sure it was certified by Hyundai in the first place @netbadger? Lots of dealers "certify" cars without using the factory certification.

    Your safest bet is to do what it's the owner's manual, not what the dealer says. Remember, the dealer cannot void your warranty, only the factory has that ability. So follow the factory maintenance schedule and keep records of it. You can dismiss, if you wish, any add-on "suggestions" for maintenance that the service writer might want to pile on.

    Installing aftermarket items that cause problems CAN void your warranty.

    Our store once took in a car that some hack had butchered by installing an aftermarket DVD player. It caused a short that took out much of the wiring harness.

    I believe the customer was able to get recourse from the shop that did the aftermarket installation.
  • Hi Can somebody please help I have a little gray area that needs clearing up?
    If I choose not to use the main dealer for breaks and disc change but an independent garage and they dont use genuine Vauxhall parts does this void my warranty cover?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    No, certainly not the warranty on the entire car. If say you use aftermarket parts installed at a non-dealer, and the calipers seize and destroy the rotors, it's possible you might lose the warranty on the rotors or calipers--but not on parts of the car that have nothing to do with the parts or repairs.

    There's no hard and fast rule on warranty denial but your owner's manual probably lays out some basic stuff, like "abuse", "negligence", "racing events", "unauthorized modifications", things like that. So yeah, if you blow your motor street racing after installing an aftermarket turbo with over-boost or nitrous, you can bet on losing your engine warranty.

  • Just checking as the main dealer is quoting on back brake pads and discs nearly £850. But an independent garage will do the same work for less than £400 but it would not be worth it if it meant loosing the warranty on the car. It is a Vauxhall Antara.

    Different countries have different laws - here in the US, as noted in the article up top, "aftermarket" work is protected by our Magnuson-Moss warranty law. Still would be a big pain if you wind up having to fight the dealer or manufacturer.

    Why would a salvage title void a warranty entirely? What about cosmetic body damage; how would that void a power train warranty?
    What is the legal basis for voiding a warranty under these circumstances?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    The legal basis is contract law.
  • drw81958drw81958 Posts: 2
    Mr_Shiftright ,
    Could you be more specific as to how "contract law" would allow a manufacturer to void a warranty (especially a power train warranty) on a vehicle that has a salvage title due to cosmetic damages, absent circumstances that show the cosmetic damage also damaged the power train. It would seem that any such exclusion would violate the Magnuson Moss Warranty Act
  • my nephew bought a used hyandui with a turbo engine, he had it less than a year. Took good care of it, noticed a knocking and took it to the delaer. the dealer assumed it was under warranty took it apart, realized my newphew didn't change the oil as it had a marked filter and then told my nephew that a new engine is needed and it cost 10k. my nephew can't afford it and then they say now he needs to pay at least 500 to put it back together. He is so bummed, i feel like they have broken some rule, maybe just need to charge him the diagnoses fee? but not 500.00 and still have no working car.

    Well I'm not an attorney so I don't know the nuts and bolts of it, but offhand I'd say that the auto company made a contract with the original owner, stipulating all of the exemptions--that is, making it a limited warranty and thus not subject to Magnuson-Moss. I know that say Mazda will void a warranty even for a car totaled from hail damage. I'm also pretty sure that automakers get all the salvage info they can, and so very often a dealer can't even enter the VIN of a salvage car in order to make the claim for warranty work. The VIN is locked out.

    I guess the best answer is that you'd have to have your case reviewed by the automaker, if you felt your circumstances exempted your vehicle for some reason.

    i have a warranty question regarding a 2016 Chevy Trax. I took it in for an oil change to the dealer I bought it from and they told me that it was due for a Throttle Body Cleaning, which if I am reading it right says that between 30,000 and 50,000 miles should be done...i'm at 40,000 so that is no issue I guess. The second one they said should be done is changing the Rear Differential Fluid...my question is, will i void the warranty if I have someone else change this other than at the dealership where I bought it...saving my receipts is not an issue, i keep them in the car. I just want to make sure that I do not void the warranty if I go to a mechanic that does not work for the dealership.

    You can't void your warranty, if the maintenance is done correctly, and with the correct fluid.

    thank you. it will be done with the correct fluids, the mechanic I use when not worried about warranty is absolutely the best...thank you for that information...it gets very confusing trying to figure this all out.
  • kyfdxkyfdx Everywhere, USAPosts: 128,067
    I have a very good independent mechanic. But, independents don't work on a lot of relatively new cars. It's possible that your vehicle uses a special differential fluid. I'd look up what's required, then ask the mechanic what he will use.

  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    Yes be VERY careful of the fluid used, that it EXACTLY meets the factory standard in all respects.

    Where are you "reading" that you need a throttle body cleaning and a differential flush? I was looking at the Trax owner's manual online and I didn't notice either of these as "factory" recommendations at those mileages. So I'd double-check your owner's manual.

    Check and make sure you aren't being "upsold" on unnecessary maintenance items.
  • thecardoc3thecardoc3 Posts: 5,091
    It's often inconvenient to mention that all of the vehicle fluids are subject to periodic direct inspection by a qualified technician and issues discovered that way that will over rule the factory recommended maintenance schedule on a case by case basis.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    Perhaps, but I don't see how a technician is going to determine if differential fluid needs to be changed without draining it in the first place.

  • I'm currently fighting with Chevrolet over them warranting my vehicles cp4 fuel pump on my 2016 Chevrolet Silverado High Country 2500HD (Diesel) w/96,000. The diesel vehicle I have comes with a 100,000 mile Powertrain Warranty and the representatives are getting confused with the verbiage in the owners manual (or whatever literature they are using to determine it’s not covered, they won’t tell me). I downloaded my owners manual from mychevrolet.com (had to put in my VIN number, so I’m certain it’s the correct manual) and it clearly states page 16 copy and pasted
    “ Diesel Engine Components
    For trucks equipped with a Diesel Engine, the complete engine assembly, including turbocharger components, is covered for defects in material or workmanship 5 years or 60,000 miles whichever comes first. Coverage for 2500 and 3500 series Heavy Duty (HD) Pickups equipped with a 6.6L Duramax, certain commercial fleet and/or government fleet vehicles is 5 years or 100,000 miles, whichever comes first. Please refer to your Chevrolet dealer for details.
    . Cylinder block and heads and all internal parts, intake and exhaust manifolds, timing gears, timing gear chain or belt and cover, flywheel, harmonic balancer, valve covers, oil pan, oil pump, water pump, fuel pump, engine mounts, seals, and gaskets...”
    Vehicle has one fuel pump, mounted to engine.
    This cp4 has so many failures there are 3 class action lawsuits filed this year.
    How do you fight Chevrolet?
    The repairs cost $12,000.
    It’s clearly stated on page 16 that it’s covered up to 100,000 miles.

    My car did not come with keyless entry. That's all I want installed. Will that invalidate my whole warrranty or just the part having to do with the door lock? Thanks.

    I purchased a 2017 honda civic with 9,000 miles on it. There was no information listed on the window, the dealership claimed they just got the car in. I bought the car and had an issue and took the car to a honda dealership bc i had problem with wipers. The dealership said that the car has no warranty and this would be bc the vehicle had major damage to it to void the manufactures warranty. I paid over 20,000 for car, which I overpaid. The dealership said they had no idea that car was in accident. I feel they knew bc "as is" was burried in the contract. i was taken advantage of and to make matters worse, dealership had a 2018 civic with ledd mileage and all kinds of features that my car didnt. Is this fraud and can i demand my money back?

    Was it a Honda dealer? I'm guessing it wasn't. Is it a new car dealer?

    If the car has a "branded" title as a total loss, and is without warranty, and they sold it to you without disclosing that, it is certainly fraud. And, you can bet they knew it.

    How long ago did you purchase the car? You'll probably need a lawyer.
