Sudden Handling Issues After Brake & Tire Service — Unsafe Bumpy Ride, Wobble, and Instability

Hey everyone — I’m reaching out to see if anyone here has experienced this.


I used to own a 2019 Prius, bought in 2020 with only 9k miles. For years, it drove beautifully — smooth, quiet, and perfectly stable even at highway speeds. But in 2023, after replacing brakes, getting four new tires, balancing, and alignment (around 130k miles), everything changed.


The car became borderline unsafe to drive:

• Constant wobbling/bouncing over small road imperfections
• Roll steer / bump steer — car pulls side to side over any road dips or drain lines
• Feels unstable on the freeway, especially in curves — I had to fight the wheel to stay in my lane
• Suspension seemed fine but nothing I did fixed it — I eventually sold the car in frustration

Since then, I’ve rented multiple 2024–2025 model year vehicles (Toyota RAV4s, Escapes, Honda HR-V, Nissan Rogue) and was shocked to find the exact same behavior in nearly all of them.


I’m starting to believe there’s a systemic issue — either a major change in suspension design, tire/suspension tuning, or possibly interference from driver assist / traction control AI systems.


I’ve filed complaints with Toyota and Honda. I’m just trying to find out if others are noticing these handling changes too, and if this could be part of a larger safety concern we should push manufacturers to investigate.


Would love to hear if anyone with Gen 4 Priuses (or others) have had similar experiences after brake/tire work — or if newer models are handling the same way.


Thanks in advance,
