When I’m reversing left or right at slow speeds make a thumping sound in my tire

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your IS350. A thumping sound at slow speeds, especially when reversing or turning, could indicate an issue with tire wear or flat spots. Flat spots can develop over time, making the tires "thump" as they rotate. Replacing your tires may resolve these noises, so you might consider installing new tires for safety and smoother operation. It is also possible that the noise is coming from something other than your tires, such as a loose splash shield or fender liner making contact with the tire. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
