I've seen some "quirks" that I'll pass along. (2016.5 SL, bought new, owned for 1 year and now at 15,000 miles)
- Twice in one day the clutch pedal/friction point dropped almost to the floor instead of being at the top where it normally is. Fixed by just pulling the clutch pedal back up. Never happened again. Probably air in the system.
- For about a week my brakes were feeling soft and spongy. Fixed it by doing a couple of (safe) hard stops that engaged the ABS. Again probably air in the system (I'll get it purged at the next service).
- Several times the EPS (Electric Power Steering) doesn't work when starting the engine. This not the normal disabling after sitting idle with ignition on. But turning the ignition off/on a couple of times has fixed it each time.
- A few times the turn signal wouldn't self-cancel. Makes a clicking sound when turning the wheel. Fixed by toggling the signals left and right and back again.
- Sometimes the radio doesn't start up properly or is locked up when the car starts. Turning the ignition off/on fixed it each time.
- One day the console screen was full of distortion/noise (although the backup camera video was still clear). Turning off/on did not fix it. But it worked fine the next day and since then. Probably moisture.
- Turning the ignition from the Accessory position to Start/On usually generates an undocumented check-engine code (0520230-31). Clears by turning the ignition off/on.
- Often the drive belt is really noisy when I first start driving, especially if it is cold or wet, and especially at lower speeds. Fixes itself after a few miles.
- I scrape the front chin spoiler more often than I'd like (on steep driveways, ramps etc). Wish it were just 1 inch higher... clearance on the rest of the body is fine.
I'm not looking for any explanations of these... they were all just annoyances that could surprise someone if they're used to a more reliable car. But they pretty much fixed themselves. Good thing because the dealer is 3 hours away and I wouldn't want to drive there every time.
But I wouldn't trade my Slingshot in for any other vehicle. Soooo fun!
Oh yeah... I'm also using up rear tires more quickly than I expected.
