Speed Bump Impact, Alignment and Steering Assist

I posted a thread in the main forum to discuss my issues with driving over a slightly troublesome speed hump. I must have attracted bad energy because I recently had a worse experience driving over a traditional speed bump (SB) located just outside of an apartment complex on my way to work. The horrible thing about these particular bumps is they are NOT clearly marked and there are NO visible signs posted on the road where the SBs were constructed. In fact, the bumps aren’t even painted yellow or white, they’re the same color as the asphalt on the road. I mean, really!? So, one day I was just on time for an appointment with 5 minutes to spare and I was likely driving at about 15mph on the road before just before SBs. I’m not very familiar with the area which is why I actually forgot they were there. Needless to say it was too late to reduce my speed to something less impactful. As I hit one, I heard what I thought was the weight of the car (frame of the car, axel or whatever) coming down hard on the SB. However, I recently learned that it is possible the sound was a result of the shocks - which is apparently very common in cases such as these or perhaps a combination of the shocks and the equipment I had in the trunk of my car. Anyway, I had a mechanic do the following inspection:

• Suspension (damage / leaks / worn components)
• Axle hub & bearings (damage / leaks / noise)
• Drive / CV shaft (damage / leaks / boots)
• Propeller / driveshaft (damage / leaks / U-joints)

They said everything looked intact, no leaks, breaks or cracks, etc. so far as they could tell, everything was in tip top shape.

Prior to this all happening, I felt that the “steering assist” was hugging the left side of the lane too tight, although, I confused it for pulling to the left. So I had the car inspected by a Certified Toyota dealer and they determined that the alignment was off and the throttle was due for a cleaning. I had both jobs completed. After getting the work done the “steering assist” seemed to work better. However, after the incident with the SB the steer assist seems to hug the left side against. I have since called Toyota back and had a long discussion with their Foreman Director. He said that there is no warranty on their wheel alignment, however they would realign it if need be with no charge and then drive with me in the car so I can explain to them what’s happening with the “steering assist”. They said they could eventually calibrate the steering assistance but it’s a complicated process. They assured me that their techs are expertly qualified to get the job done properly.

So now I’m wondering if anyone in the is forum has had a similar experience with speed bumps, steering assist that needed to be calibrated properly? I guess, ultimately I want to know if I’m going about getting this issue resolved in the right way?

Thanks for reading!
