My favourite was when the exhaust pipe gasket went. It was a ~$20 part (dealer marked up to $70ish)
https://www.ebay.ca/i/122641137302?chn=ps&dispItem=1Took 4 dealers to diagnose the problem, all of whom said "cannot recreate complaint" and then wanted to charge me for 0.5 hrs of diagnosis time because no warrantable problem was found. Finally, it was found, and then the dealership said, "part not covered under ECP".
I pulled up the brochure, which said:
The ECP Platinum Plan Coverage is so comprehensive that there are only a few items that it does NOT cover.
Parts not covered are: all glass (mirrors, heated windshields and rear windows with defroster), fog lamps, lenses, sealed beams, lamps, light bulbs, tires (with the exception of ECP Road Hazard Coverage), wheels or wheel studs, trim, seat frames, convertible top, mouldings, weather-strips, bright metal, sheet metal, body parts (including frame), bumpers, upholstery, carpet, paint, brake rotors and drums, brake linings and pads, batteries and cables, manual clutch disc lining, pressure plate and bushings, throw-out bearings, catalytic converter (which may be covered by Emissions Control Systems Warranties), exhaust system, non-manufacturer installed accessories
In addition, maintenance services and parts; including all lubricants and filters, belts and hoses, wheel balancing or alignment, any adjustments for air and water leaks, wind noise, squeaks and rattles as well as alignment of bumpers, sheet metal, and body parts covered.

The dealership told me to call Toyota directly. I did, inquiring "I'm told the part is not covered. Why is the part not covered considering that the brochure clearly indicates that it is? They said, "we'll look into it." I got a call back 2 weeks later saying, "we looked into it, and the part is not covered." I called back, saying, "I asked WHY the part is not covered considering the wording of the brochure, and the response was that the part is not covered. That doesn't explain WHY." I received a call back two days later from the dealership saying "we'll honour the warranty." Never heard back from Toyota Canada.
Seriously, over $70ish, Toyota royally p!ssed me off. I'm not rushing back for their products as a result (shame since I really did love the 'Rolla).
