2017 Toyota Corolla: grinding or squealing brakes

Filed Oct 16, 2025 · Driver assistance, Engine · FL

When the cruise control is set and I go down hill my car increases the speed by 8 mph faster than the set speed. My car also makes a loud grinding noise when it does this. I spoke with different Toyota auto employees and some say that the increase in speed and noise are normal and others say the opposite. I have been in many cars driving with cruise control on and never experienced this.

My brakes seem to malfunction when engaged after hitting potholes and/or street depressions. This has occurred on Kensington Street east of Church Avenue. This is between Church Avenue and Dale Mabry Highway among other streets. My safety was put at risk as I felt the brakes were not going to hold or stop the vehicle. No, it has not been attempted to be duplicated. When my brakes were inspected, I was told everything was fine. It seemed no one was interested in driving the vehicle over a pothole and/or street depression. Why would it be inspected when a Toyota Dealership and Firestone reported my brakes were fine without duplicating the situation in which I had a problem. No warning lights, lamps, messages. My 2 front tires continually lose air down to 28 and 29 psi from the 32psi. I will be taking the car back to Firestone for them to check the two front tires that I purchased from them. In case something happens to me or others reporting this problem, I wanted proof I informed you of the issue I had. The contact stated the vehicle still makes a grinding noise when brakes are applied during and after rain. Also, the brakes were inspected but that wasn't the problem. Gettel Toyota mechanics stated the vehicle needed struts but instead Toyota replaced the shock absorber. The problem still occurs.

When purchasing the car and leaving the car lot I heard a grinding/rubbing noise which sounds just like brake pads being worn as well as rotors. I contacted the car lot and they assured me it was from rust where it had sit. They had me take it to toyota of kingsport and they evaluated stating it was rust. I still hear the rubbing or loudness after they replaced the rotors. Please recall

Vehicle was stopped at a traffic light and when the light turned for a left turn I tried to accelerate to get through the intersection when the vehicle lost power. This has happened on three occasions and I took it to the dealership to get it checked and they said they could not replicate it. Transmission has not been shifting correctly and now the transmission is making a strange grinding noise. This corolla has a CVT transmission and the toyota corolla forums are telling me that toyota is aware of this problem and had issued a special service campaign to update the software. This has since been rescinded because the update did not fix the problem.I have read that this loss of power is causing some serious safety concerns, especially if it happens on high speed highways.

I bought my car brand new in april of 2017 and had nothing but problems, tires are always flat, steering doesn't work right, when I turn my car on it sounds really loud. Brought it toyota 10 times and they did anything, there is constant squeak noise and my roof feels like it's going to blow off when I am on the interstate. Gas mileage sucks toyota states I got bad gas so they flushed it out but still hear that loud noise. My tires I have to fill up once a week but they say they are fine. Everything in this car is cheap and I hate it. They charged me 26 grand for a 17 thousand car without me ever knowing brandon toyota is the worst. Spoke to the general manager and service manager nothing is ever taken care of

I was driving home on hamilton road, in columbus, ohio, at 535pm. I noticed that my headlights weren't on, when other drivers were trying to worn me. I set my headlights on automatic when I first received the car. I finally found the switch to turn my headlights on manually. Then my car started to brake 10-15 feet from the car in front of me, my tires were squealing. My foot was not on the brake pedal it was still on the accelerator. It was too late I hit the SUV in front me. My air bags didn't deploy. The accident avoidance system didn't activate until to late. It is clear that the car responded after the headlight switch was manually turned on instead of being in the auto position. It was suggested at a dealership earlier that cycling the navigation system on the car could inadvertently disarm it. If that were the case and it was off accidently why did the car try to brake at the last second on its own by turning on the headlight switch. This car was purchased for the driver for the very reasons of its safety features unfortunately this car completely failed to protect the driver. That is why I feel like this should be looked at immediately to see if this is a mechanical issue, program issue, or simply driver error, which I do not believe at this point. I have photos of vehicle and interior which I am unable to upload on this site, they are available upon request.

My new 2017 corolla has squeaky brakes right out of the showroom when I apply the brakes every time, and continues to do so.
