They may exist, but I'm not aware of any car company that REQUIRES maintenance performed by a dealer to keep warranty coverage. I don't know if there's a law against it, but I've never seen such a requirement.
For grins I just went through the Warranty and Maintenance Manual that came with my 2008 Lancer ES. Unless I missed it, there is no language that comes close to stating a requirement for dealer service (or any exclusion of DIY) to maintain the warranty. The closest thing I saw is language on p. 34 that says, "Your Mitsubishi Motors Dealership is in the best position to provide proper maintenance service . . ." If anything, this is a plea to bring your car to
for service. I think there is thus an implication that you might take your car somewhere else or DIY.
On page 9 I see the following: "Receipts covering the performance of maintenance services should be retained in the event questions arise concerning maintenance. These receipts should be transferred to each subsequent owner of this vehicle. MMNA reserves the right to deny warranty coverage if the vehicle has not been properly maintained. However, denial will not be based solely on the absence of maintenance records."
Notice it does NOT say, "Warrantly coverage WILL be UPHELD based solely on the PRESENCE of maintenance records." However, it's a fairly clear implication that if you do your work somewhere other than
, you have a reasonable expectation of keeping warranty coverage if you document the service.
There are no guarantees, but the implication is that if you bring a car with a blown engine (etc.) to
and expect warranty service, they may try to deny coverage if they can make a case that you did not properly maintain the car. If you have been bringing your car to a
dealer religiously for service, and have the records to prove it, then
has no leg to stand on in denying your claim. If you have been doing the maintenance yourself, then you should have documentation of this to back your position.
Possible scenario #1: Your motor blows at 50K miles and you bring your car in to have it fixed under warranty. The
dealer says it appears that your oil is too old/not the proper grade, and they won't cover you. You have no evidence to support the contention that you have been maintaining your car properly. You're likely screwed.
Possible scenario #2: Your motor blows at 50K miles and you bring your car in to have it fixed under warranty. The
dealer says it appears that your oil is too old/not the proper grade, and they won't cover you. You show them your Warranty and Maintenance Manual with receipts stapled in place for each service, dates, boxes checked, etc. I guess some dealers might protest, but I think most will cover you. If the dealer is a dick about it, be aggressive, threaten legal action, communication with MMNA, etc. If you have the documentation, then I think the law is on your side (but I'm not an expert on the law).
Consider this as well, what if you were taking your car to a Jiffy Lube or independent mechanic for regular maintenance. Assuming you kept records, do you expect
would honor that? I think they would. Think of how many soccer moms and *****-less men use Jiffy Lube. (Just kidding about that *****-less thing, but I couldn't help it
) I don't think
or any other car maker is denying them warranty coverage for using Jiffy Lube. Well, how are receipts from Jiffy Lube any better proof of maintenance than receipts for 5W-20 Mobil 1 from Wal-Mart? Does a receipt from Jiffy Lube prove that the tech put in the proper amount and grade of oil? Who is to say the tech didn't drive your car into the service bay, eat his lunch, then pull it back out and hand you the keys?
So, I guess my point there is that I don't think
could argue against DIY work any more than they could argue against work done by Jiffy Lube or any other non-mitsu mechanic--assuming records are in order.
I may (note, MAY) bring my car to a
dealer for the 60K service. Why??? Well, at that point I may just want another set of eyes taking a look at things. I think I know what I'm doing when I look at CV boots, suspension components, etc., but I'll admit that a trained
mechanic might see something that I missed. If I were to have a problem further on down the road (literally), then I would at least have one data point where the dealer gave the car a seal of approval. For example, if I have a problem at 73K the dealer can't say the car has been neglected for 73K miles and it's all my fault. That being said, I don't think I could stand having a dealer charge me hundreds of dollars to install spark plugs, change oil/filter, and replace a couple of air filters. Maybe I would find out what
would charge if I did all the installing/replacing myself and just wanted them to do what would basically amount to a safety inspection.
Anyway, I just did the 37,500 maintenance on 10/24/09, and it's all documented on page 38 of my service manual, along with a receipt from Wal-Mart showing $22 for Mobil 1 5W20 and $4.24 for an oil filter. No Jiffy Lube or anyone else will do an oil change with synthetic for $27.82 (tax), and it takes me less time to DIY (even with a tire rotation) than it would for me to drive into a Jiffy Lube and wait for them to do the work.
