Service brakes, hydraulic:pedals and linkages

Honda (American Honda Motor Co.) is recalling certain 2021-2025 Acura TLX, 2023-2025 Acura MDX, and 2023-2025 Honda Pilot vehicles. The brake pedal pivot pin was not secured properly, which can cause the pedal to shift out of position.

In owners’ own words

Power train mileage not reported 2.3 yr in service
Noticed my 2021 Acura TLX A-SPEC SH-AWD has fluid leaking from the rear differential where the driveshaft connects. The vehicle has 16,531 miles on the odometer. Honda is releasing a recall for leaking rear differential on the Honda CRV as well Accords. Honda may want to include the Acura TLX's as well in the recall as they are reporting the drivesshaft may cause serious damage at high speeds if the differential is leaking.
Power train mileage not reported 4.6 yr in service
Transfer case broken; no longer sending power to the rear wheels. Car loses traction when accelerating from a stop.
Power train mileage not reported 4.6 yr in service
My car has suffered a well known issue in the 21-25 Acura TLX community. At 71,000 miles my transfer case splines stripped also with the transmission splines. Resulting in me having to pay out of pocket to replace both the transmission and transfer case. I’m really hoping Acura does a recall for this issue. I really like this car and don’t want to have to replace them again. Like I mentioned before. I’m in a Facebook tlx group and people are constantly posting about theirs blowing.
