Q: I purchased my 2017 Equinox new and thought any problems with it would be covered by warranty, but I’ve run into problems where things are not really covered. How does this work?

Warren T. – Portage, MI

MM: Warren, there is a lot that is covered by warranty, and in some cases, not covered by warranty. Rules, mileage and sometimes what is covered varies from model year to model year. And without knowing everything about the issue you needed repaired, what kind of mileage you had at the time of your visit, and other factors, I can’t exactly pinpoint why something wasn’t covered. 

Generally, on today’s vehicles, or rather the 2019 vehicles you can purchase right now, GM offers a 3-year/36,000 mile Bumper-to-Bumper warranty and 5-year/60,000 mile Powertrain, with the exception of the 2019 Silverado 2500 and 3500 Heavy Duty pickups with the 6.6L Turbo-Diesel V8 engines which are covered under a 5-year/100,000 mile Powertrain warranty.

Electric and Hybrid vehicles fall under an additional warranty covering 8-year/100,000 for electrical and battery components.

Now what that coverage entails, it depends on the situation and the warranty, and varies even with year, make, etc. I’m providing a basic overview on the basics.

Bumper-to-Bumper

Bumper-to-Bumper warranty usually covers any defects or issues with the vehicle, caused by defective parts, systems, or workmanship from factory to you. The idea is your vehicle should run fairly well those first 3 years or 36,000 miles and need nothing more than maintenance items.

Things like non slight noises, vibrations or other normal characteristics of the vehicle due to materials or workmanship would be covered.

Items beyond that in some cases can be covered, and those can fall under a recall or special coverage via General Motors. The more frequent the issue is reported, the sooner it might be reported and covered by GM.

Note that this warranty does not cover any maintenance services such as oil changes, alignments, filters, etc.

Powertrain

Powertrain warranty covers more specific components which would relate more to things like your engine and transmission. This list includes, as stated by GM: “all internally lubricated parts, engine oil cooling hoses and lines, actuators and electrical components internal to the engine (i.e. Active Fuel Management Valve Lifter Oil Manifold) cylinder head, block, timing gears, timing chain, timing cover, oil pump/oil pump housing, OHC carriers, valve covers, oil pan, seals, gaskets, manifolds, flywheel, water pump, harmonic balancer, engine mount, turbochargers, and supercharger. Timing belts, and other associated components required in the timing belt service replacement procedure are covered until the first scheduled maintenance interval.”

This is really just a snapshot of what is covered. If you’re feeling a need to be enlightened on the ins and outs of warranty coverage, you can spend a couple hours reading through the specifics of multiple coverages offered here. Note again, this can vary, so looking into what’s covered under your specific vehicle’s year and coverage is highly recommended.

On the plus side, we and other dealers offer extended warranty coverage you can purchase, as well as third-party warranty coverage, and what those cover depends on the terms they’ve outlined.

I’m sorry your repair may not have fallen under any of the aforementioned stated warranties. In any case, if you have further questions (or curiosities), your service advisor or the dealer warranty administrator should be able to guide you through your coverage.

 

Q: I wanted to know the price of a 1997 Camaro used engine.

Eugene D., Plainwell, MI

MM: Hey Eugene. I think you may have emailed the wrong person or department, but I appreciate the note because it does bring up a good topic.

While dealerships have many parts on hand, the things typically in inventory are limited and not usually for something quite as old. Here, we tend to stock parts for the problematic vehicles we see with the same issue, often, and a little newer in age. For instance, we generally have the last generation Cruze’s turbos on hand, because at this age and mileage, they need replacing.

For your specific needs, I was directed to what I think is a handy website that takes the need for finding and calling multiple vendors for parts out of the equation, and converged all their inventories into one place. Head to Car-Part.com, and from there you can search and organize your search to find what parts, or in this case engine, is available, potentially the mileage and other information.

Having grown up with a mechanic in the house, this is revolutionary compared to spending an afternoon hopping from one junkyard to the next to see if you could find something you need and in the preferred working condition you would like it to be in.

Happy Hunting! And have fun with your (I’m presuming) project car!
