Are you required to service your car at the dealer to preserve warranty ?

For warranty validation? If an engine fails and you change your own oil, is that a problem for warranty service? Most extended warranties require you do all maintenance at the dealer, so I am wondering if the OEM requires the same. I have never brought my vehicle to the stealershit for maintenance, I always do it myself, but I have never had an engine or transmission fail, so I am curious what would happen if I did experience such.

I always have mine serviced at the dealer during the warranty period. I've done that with every new car I've owned. It is a bit more expensive, but everthing is fully documented in the Ford database. Also, I've seen some sloppy service from the independent oil change shops. I think it is better to have my dealer familiar with the vehicle itself if something comes up. Also, the dealer often seems to find stuff that an oil change store won't - and it is under warranty, so they are not trying to make money, just keep the car up to snuff.

 

But legally, it is not required, so long as you keep your receipts.

Yeah, but his question was about Doing It Yourself.....A.K.A. DIY

How about with Ford ESP, can you do your own maintenance and still preserve your ESP? I know some aftermarket ESPs require all dealer maintenance, otherwise they wont cover a repair.

I don't know, but I've never heard of such BS. Repairs are usually required at the dealers, but not maintenance.

 

Find your ESP policy or check with the seller.  Read this...

Anyone know which ESP I would have to go with to cover all the most expensive portions of the vehicle like the hybrid system, tranny, engine, DC/DC converter, ect? Ford's website does not say which plans cover hybrid systems and which do not. I was originally going to just go with the basic care plan.

The hybrid systems should be covered for 8 years. See you owners manual for that info.

Every state has different requirements. CA has 10 years and 150K miles on my EV battery

and 8 years 100K on everything else. Or you can go to the Ford website and get the info. from

the online manuals.

Does the hybrid system include all electronic components including the electric motors? I was always under the understanding that warranty only covered the battery. Everything else is covered under bumper to bumper or powertrain.

You need to read the Ford New Car Limited Warranty (it's available on-line).  Here's what I posted in another thread.

 

The Ford Warranty covers the hybrid components for 8 yrs / 100 k miles (longer in CA). See below for Hybrid components covered.  Major emission systems are covered for 8 /80 k miles (see below).  The rest of the Power Train is covered for 5/60.  So, if one is buying an extended warranty because of the new hybrid technology, it's already covered for 100 k miles.

Hybrid Component Ford Warranty:

The following hybrid parts are covered during this extended coverage

period: high-voltage battery, hybrid continuously variable transmission,
Inverter System Controller (ISC), DC/DC converter, high-voltage
battery connector, battery pack fan assembly, thermistor probe, Hybrid
Battery Pack Sensor Module (HBPSM), Battery Energy Control Module
(BECM), and the PHEV onboard charger.
 
Federal Major Emissions
8 years or 80,000 miles (whichever occurs first) for catalytic
converters, electronic emissions control unit, and onboard emissions
diagnostic devices, including the Battery Energy Control Module
(BECM).

hmmm interesting that the transmission is considered hybrid and therefore covered to 8/100k. Also interesting that the MG1 and MG2, however, are not covered since they are clearly specific only to the hybrid system.

 

MG1 and MG2 are internal parts or the transmission and also part of the hybrid system.

MG1 is the hybrid systems 12V system charge motor and the HVB regen motor through the inverter

and battery control module systems.

MG2 is the electric drive motor and therefore part of the transmission.

They are the transmissions core units and without them, you go nowhere.

Hua, I always figured a 36kw motor would be pretty huge. I mean your alternator in your car can only produce about 1500W, and so I figure a 36kW motor would easily be 10x the size of an alternator.

Any photos of the MG1 and MG2? How does MG1 charge the 12v? I though MG1 goes through the inverter to get stepped down from 600V to 300V, or whatever the HVB battery voltage is (300V ish), and the 2000W 300V to 12V inverter provides 100% of the power to the 12v system? What voltage does MG1 and MG2 run at? I know in the Prius the voltage is almost doubled from the HVB to the motor through the inverter.

So when they say MG2 is 36kW, is that 36kW draw or 36kW output?
