2021 Lexus RX

There is a 'clunk' in the rear when I hit a bump just right. AI says it could be a rear trailing arm bushing. Why is this not a safety issue ?

Electronic Parking Brake (EPB), 12V Battery/Electrical System. My vehicle's 12V battery failed, with the dealership measuring voltage below 10V during the event. This caused multiple simultaneous module malfunctions (confirmed by the dealer as caused by the battery failure), including a complete inability to move the vehicle after jump-starting on three separate attempts — the engine ran, but the vehicle would not drive despite a functioning alternator. The vehicle's steering wheel also locked, preventing the car from being pushed to a safe location. Approximately 3 months after this event, a routine service visit revealed the rear brake pads had worn from 8mm (measured at time of purchase) to 2mm (failed), while the front pads wore from 10mm to 7.8mm (normal wear) over the same period and mileage. The rear pads wore roughly 3 times faster than the front, which is inconsistent with normal vehicle operation, since front brakes handle proportionally more braking load and are fitted with larger rotors for this reason on this and virtually all vehicles. The rear brake caliper is the only caliper equipped with the EPB motor/actuator; the front calipers are purely hydraulic. The selling dealer's pre-purchase report also noted noise from the rear brakes at time of purchase, which is consistent with the EPB's position calibration having been disrupted at some point prior to my ownership (e.g., from a prior battery event or service) and never properly relearned/recalibrated afterward — producing a low-level drag from the outset. My own battery failure event (voltage measured below 10V) would then have compounded this already-uncalibrated system, worsening the drag and producing the rapid 6mm of wear observed in the following months. This points to one underlying EPB calibration fault, aggravated by repeated voltage instability over time, rather than an unrelated mechanical issue — see attached documents for more information.

The tire (Bridgestone Ecopia 422 Plus 235/55R 20 102V M+S) failed within seconds while driving on the highway at 70 MPH. Luckily I did not lose control and was able to steer the car from the middle lane to the birm thanks to the semi driver on my right who allowed us to get off the road quickly. There was almost no rubber remaining on the rim and the tire pressure sensor was gone. The tow truck driver and NTB tire technician said the tire appeared to have failed due to delamination of the steel belt. Subsequent searches on the internet seem to support belt failure as the cause of the rapid loss of the tire. Walmart has refunded the cost of the failed tire. Bridestone is being less than helpful relative to the remaining three tires, which have less than 2,000 miles on them.
