I'm two months into ownership and love driving my Longhorn. It performs as advertised and towed my enclosed car trailer to a track event with no problem.
I do have several annoying gremlins, that are entirely related to electronics. These started from day one and I pointed them out to dealer before signing paperwork.
Here are the error messages I've received very regularly.
- Service Electronic Throttle Control
- Rear Parksense Temporarily Unavailable
- Trailer Steering Unavailable
After dealership intervention, the Service Electronic Throttle Control message appears much less frequently (but not never). The other two, however, happen nearly every drive. The few times I've actually tried to use the trailer steering function, it's never worked. This isn't a big deal since I know how to reverse my trailer using mirrors, but I still have no first-hand experience with this feature because its never worked.
Two other electronic gremlins don't post error messages, but the errors are apparent.
- Cameras (rear & surround) don't function upon request (either shifting into R or calling up surround via the display). This occurs roughly 25% of the time and it can happen within the same ignition cycle that it worked properly already. So far, this has been remedied by turning the truck off and back on again. Inconvenient at best and dangerous at worst.
- When using CarPlay, it doesn't always allow me to play audio from the regular radio (XM/FM/AM).
The driving and functionality of the truck has been perfect, so I'd rather have electronic gremlins than drivetrain gremlins. But for a $70k luxury truck, you do expect the full features to work properly.
