YES! Love the analogy. That's hilarious.

To answer your previous question the steering rack was worn, allowing 40° play in the steering and the tires worn as well. So imagine turning your steering 1/8 of a turn and it not moving. So we’ve been occasionally just going down a roof that had grooves in. It could sit off the warning sensor but maybe not the brakes.

The brakes don’t remain on. They self apply at very inopportune times. Such that it makes a situation dangerous. For instance, my wife was entering a major highway on an entrance ramp to a major thoroughfare the play in the wheel caused the steering angle sensor to activate the brakes every time she would depress the gas. While trying to accelerate out of the corner as you would expect yourself and the vehicles behind you to do the same. Except out of nowhere someone slams on there brakes a few times. Because the system doesn’t just turn off it remains active for a few seconds after the initial event. The semi behind her, just about ran her over. Or if you have an angry person behind you. You may get shot. So if you think about the number of times, you accelerate out of a corner while driving to work or anywhere, this becomes a very dangerous situation.

It was in need of tires. When on the rack I had prearranged for inspection and had mentioned the issue. The mechanic showed me what was happening. Described how the loose components lead to the steering angle sensor being the secondary reaction to the actual problem. Having driven it to work A couple days to try to surmise the issue for myself. His explanation made complete sense.

12-23-22 We replaced the steering rack, left CV axle and the sway arm linkage. We also had alignment done and recalibrated the system. after putting new tires on as well. This was the the cure needed. The play in the steering rack caused the the problem, with the steering angle sensor to be off by up to 40 degrees off. Now operates perfectly.

Gas cap yes. As for the battery I will check it in the morning.

I haven’t found anything yet either but going for new tires(12-17-22) going to check TPMS monitoring and chat with mechanic tomorrow.

On a 2004 RX 330 I discovered while, cruising above 40 mph, turning slightly to the right, and slightly to the left the VSC light would come on and beep. Then, when turning a little more (but not hard), to the right or left. He would begin breaking until you let your foot off the throttle, and then it would slow naturally. However, when you would begin to reapply the throttle, it would begin breaking again. This creates a very dangerous situation on an acceleration ramp when everybody else is trying to speed up. It is also very dangerous on a deceleration ramp as it brings you down below this necessary speed to make the curve abruptly. I have spent about eight hours over the last three days researching this, and only coming up with links to turn off the VSC and ABS light on the dash. I have also tried to re-calibrate it using the OBD connector for its auto diagnosis program. Unfortunately, this also had no effect. It seems as if the sensor is too sensitive to turning. Does anyone know if it would be the TPMS monitoring possibly triggering it or some programming within the ECM module? any help would be appreciated. Thanks.

I just bought a 2004 RX 330 and I’m having the same problem. Only seems to do it above 40 mile an hour and only in an S curve when accelerating. once you let your foot off the accelerator, the braking stops and the vehicle just slows normally. Putting new tires on tomorrow and having to TPMS checked as the tire pressures were correct. Will update as soon as I figure something out after three days of research have not found anything until I found this link. 12-17-2022 So here is what’s up. It’s a combination of things. Ultimately it is the steering angle sensor setting off the problem. Using an advanced scanner. The mechanics at Tires plus in Hunters Creek, FL diagnosed that due the worn steering rack the play in steering wheel was 40 degrees off on the right and 10 to left. There by at certain times I could be 50 degrees off when guiding my vehicle down the road. So now scheduled to put a new rack, left strut, sway bar link, and an alignment. Then all should be good for a while.
