Hello Everyone! I just joined the forum because I felt compelled to add my experience to this group. I have a 2018 C-HR XLE purchased new in mid-2017. I bought the prepaid maintenance plan as well, and have religiously brought my car in to the dealer at every 5,000 miles for scheduled maintenance.
I have had issues and alerts with the EPB (parking brake) system since the car was new. The first maintenance on this issue was at 4,000 miles but has continued throughout its life and I just hit 65,000 miles. I have never even used the parking brake! These EPB issues have always caused other systems to malfunction as well because they work together. The main one is the cruise control. When I took the car in for its 60,000 mile service a few months back, I complained that I was receiving EPB alerts and that it needed action...yet again. It was also making a noise that I was unfamiliar with and I thought might also be related to the EPB system and the work that they have performed on it.
The noise was directly related to TIRE speed, not engine speed. It starts at about 10 mph and its frequency increases as the tires go faster. I would sometimes put the thing in neutral while travelling down the highway and the noise frequency wouldn't change even though the engine speed dropped to idle, so I had ruled out anything related to the engine/transmission. Perhaps it was just the tires getting worn even though I could find no cord exposed and still have plenty of tread on them. I almost went and bought a set of 4 tires to cure this maddening noise!
Yesterday I took the car in for its 65,000 mile service. On top of the normal scheduled maintenance, I asked them to check the noise that I have been listening to for at least the last 5,000 miles. I told them that I suspected that it was somehow related to the EPB work that had done because it seemed to get worse as soon as I got it back from the shop last time. Nope! After a day of troubleshooting, they call to inform me that it is the transmission, fluid smells burnt, and it's toast. And they told me about this forum and that it's a "known issue". My car is now out of warranty. I had never heard of any problems until I read this forum last night. The dealer is working with Toyota to try to get it covered, as I was having this issue while it was under warranty. I just didn't know what it was. I never dreamed it would be the CVT.
I will find out on Monday what Toyota decides. It will definitely have an impact on my purchases in the future. If I have to pay out of pocket for this, I just don't see it being worth it based on the value of the vehicle. I've always thought that I would be able to get like 300,000+ miles on my Toyota.
