Our car: 2019 Model 3. Our last 3 trips on the I-5 North from Orange County, CA to LA County, CA, a sudden unexplained slowing occurred at almost the exact same place and around the same time. We were using Cruise Control with Auto Steering. Here are the details from our notes:
5/12/24, 9:50am: driving N on I5; abt 1 m before Westminster Blvd Exit #19; abt 200yds before seeing Westminster Blvd, 1 mile sign; abt 50yds before going under overpass; going 70mph on Cruise Control (and auto steering); clear lane ahead; suddenly slowed from 70 to abt 45mph; after 5-10", corrected to 50mph on Cruise Control.
5/19/24, 9:50am: driving N on I5; abt 1 m before Westminster Blvd Exit #19; abt 200yds before seeing Westminster Blvd, 1 mile sign; abt 50yds before going under overpass; going 70mph on Cruise Control (and auto steering); clear lane ahead; suddenly slowed from 70 to 45mph; after abt 5" I accelerated back to 70mph, then restarted CC; it had self corrected to 45mph.
6/9/23, around 9:10am: driving to Lisa's in Culver City; N on I5; abt 1/4 mile before Magnolia Exit; going 75mph on CC; sudden drop in speed to 65mph for no reason, I quickly returned CC speed to 75mph; then, very shortly, abt 1 m before Westminster Blvd Exit #19; abt 200yds before seeing Westminster Blvd, 1 mile sign; abt 50yds before going under overpass; going 75mph on Cruise Control (and auto steering); clear lane ahead; suddenly slowed from 75 to 45mph; after abt 5" I accelerated back to 75mph, then restarted CC; it had self corrected to 45mph (this was almost identical to events on 5/12 and 5/19.
Weird!!!???
