2019 Toyota Corolla Driver assistance Problems

The emblem on my car contains a sensor/radar for adaptive cruise control and foward collision warning that is also connected to automatic emergency brakes. The safety of me and my [XXX] old are at risk because if I needed assisted braking/collision warning, my car no longer provides that. The braking on my car feels as if I am needing to apply a lot of pressure on the brake to stop completely or even to come to slower speeds to adjust to traffic. The problem was reproduced prior to me officially picking up my car on [XXX]. The estimator told me that he isn't quite sure what is causing the sensor issue but according to the calibration system it is working fine and he doesn't know how to fix the issue. As for the brakes he said that they feel fine to him. My car was inspected by Crash Champions and I have been told that my vehicle feels fine and the sensor is working fine according to the calibration system. My car did not originally have this issue until after an accident on [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

As I was driving my check engine light turned and also another message saying “Drive-Start control malfunction”. A few second after another light came one showing “Engine coolant Temp high. On 11/24/24 I experienced this mechanical failure as I was driving. I was driving behind another car, where my car suddenly lost power and randomly accelerated almost causing me to crash behind the car in front of me. Thankfully I had time to press on the brakes to prevent me from crashing. I also did some research to see if other drivers also experienced this fault and seems that a lot of people with these Toyota Corolla and RAV4 models. I also found that an active lawsuit is ongoing against Toyota regarding this same issue. This definitely should be something that needs to be recalled as it puts our lives at risks to either crash or even catch on fire due to overheating. My vehicle gets serviced regularly.

At around 36,500 miles, my Toyota Corolla began experiencing issues with the coolant bypass valve, leading to engine overheating. This malfunction has significantly impacted my ability to drive safely, as the vehicle displays a notification every five seconds, obstructing my view of the digital speedometer and making it difficult to accurately monitor my speed. The issue was not indicated by a check engine light but a persistent "Engine Maintenance Required" message. This defect poses a serious safety risk, and there's a potential class-action lawsuit in progress regarding this very issue, suggesting Toyota might have known about the defect but failed to disclose it. The faulty component is not available for inspection upon request. As more people began to experience similar circumstances, it could lead to fatalities. Other participants to the forums says the issues start when their covered warranty expires. Within these forums there's a inconstancy of service centers honoring fixes, with no cost, knowing that there is an issue. I took the car to both a third-party mechanic and an authorized dealership, and both confirmed the problem. I was quoted $732.85 for the parts and labor within my area. I also called Toyota Global which I was told "a low mileage car shouldn't be having this issue", however, there are countless of forums saying otherwise. **Toyota Models Affected** 2019 Toyota RAV4 2020 Toyota RAV4 2021 Toyota RAV4 2022 Toyota RAV4 2023 Toyota RAV4 2019 Toyota Corolla 2020 Toyota Corolla 2021 Toyota Corolla 2022 Toyota Corolla 2023 Toyota Corolla [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On June 15, a message appeared on the multi-informational panel that the pre-collision system was unavailable. An orange warning symbol also appeared on the dash. Car was repaired a at Kendall, Toyota, 10943 S. Dixie Highway, Miami, FL 33156 in Kendall, Florida. The Millimeter Wave Radar Sensor was replaced. The unit itself cost $843 and replacement labor was $350. Like other Toyota radar sensors, I believe this one has design defects. It is a safety issue. I assume that many people will not replace it. The message on the panel does not say the unit needs replacement. I retained the faulty unit and it is available for inspection. It is Toyota part #88210-07010. There are no signs of damage that I could see. The unit has not been open and I have put it in a baggie. It has not been inspected by anyone. The new part has the same part number. There were no prior warnings or symptoms.

Phone charging cord is prone to getting pulled into the steering column and extremely difficult to remove. When I was able to remove the cord, I discovered a wire or spring the steering wheel assembly must have come undone, because the airbag light is on, and my cruise control no longer works, and neither do the steering wheel controls for the radio

1. Cruise Control 2. Unknown 3. No 4. No 5. No I first reported this to the dealership shortly after I purchased the vehicle. While driving with the cruise control on the rpms begin to jump to 5000 all on it's own but the car isn't speeding up when it happens. I know it's wearing the engine down every time it happens. It happens when I'm driving on flat freeways as well as when driving down hills. The dealership dismissed what I was telling them, but I know there's something not functioning properly and would like it further looked into.

I reached a hill using the cruise control at 65mph. The vehicle accelerated to account for the loss of speed due to the hill. The engine accelerated the vehicle to well over 70 mph and revved up to very high rpms. The engine remained at high rpms and higher than normal speeds until I manually disengaged the cruise control. The engine should not be revving up to and remaining at such high rpms for such an extended duration.

THERE IS A SEVERE SAFETY ISSUE WITH THE CRUISE CONTROL. IN READING COROLLA ON-LINE FORUMS, IT APPEARS THAT IT HAS BEEN A TOYOTA PROBLEM FOR QUITE SOME TIME ' NOT SOMETHING SPECIFIC TO MY VEHICLE ALONE. THE FIRST COUPLE OF TIMES I HAD TO TAKE IT OFF CRUISE - AS IT WASN'T SAFE IN ANY WAY. THE LAST TIME I SET IT WELL BELOW THE DESIRED SPEED WITH NO OTHER VEHICLES IN VIEW SO THAT I COULD TRY TO ALLOW IT TO RUN ITS COMPLETE CYCLE. I WANTED TO SEE EXACTLY WHAT WOULD HAPPEN IF ALLOWED TO RUN ITS COURSE. WHEN I SET THE CRUISE CONTROL, IT SETS FINE. THEN, WHEN I GO DOWN A VERY SLIGHT DOWNHILL, THE ENGINE REVS WILDLY UP TO 4000 RPM, HANGS THERE FOR A LONG WHILE AND PULLS THE CAR UP WELL OVER THE SET SPEED. THEN IT DROPS, INEXPLICABLY, TO APPROX. 3000 RPM, HANGS FOR A BIT, AND THEN DROPS DOWN TO WHERE IT SHOULD BE - APPROXIMATELY 1000 -1500 RPM AND THE SPEED GOES BACK TO NORMAL. WHAT GOOD IS A CRUISE CONTROL IF YOU NEED TO BABYSIT IT? YOU SHOULDN'T HAVE TO TAKE IT OFF BECAUSE IT'S ACCELERATING RAPIDLY OUT OF CONTROL! I READ SOMEONE'S ACCOUNT OF THEIR CAR ACCELERATING UNTIL THEY CAME UP BEHIND SOMEONE ELSE, THE CAR BRAKES CAME ON, AND THEY WERE NEARLY REAR-ENDED BY THE PERSON BEHIND THEM BECAUSE OF THE SUDDEN BRAKING. IT SOUNDS LIKE A TICKING TIME BOMB!

WHENEVER CRUISE CONTROL IS APPLIED AND I'M GOING DOWNHILL ON THE HIGHWAY, IT WILL ACCELERATE 5 TO 10 MILES AN HOUR AND THE RPM HAND WOULD REV UP DURING THE EXCESSIVE SPEED UP. I WAS TOLD THIS IS NORMAL BUT I DON'T THINK SO.

WHEN CRUISE CONTROL IS ENGAGED AND THE VEHICLE IS TRAVELING DOWN AN INCLINE IT WILL ACCELERATE 5-10 MPH OVER WHAT THE CRUISE CONTROL IS SET AT. FOR EXAMPLE IF I HAVE IT SET AT 65 MPH IT WILL ACCELERATE TO 75-80 MPH ON IT'S OWN. I BROUGHT THE VEHICLE IN FOR THIS TWICE NOW AND TOYOTA CAN NOT FIGURE OUT WHY IT IS HAPPENING. THE RPM'S WILL GET UP TO 4000 AND ONCE THE VEHICLE IS LEVELED OUT AGAIN ON A FLAT ROUTE IT HARD BREAKS TO SLOW THE VEHICLE DOWN.

EVEN ON SMALL HILLS IF THE CRUISE CONTROL IS ENGAGED, THE MOTOR WILL RACE TO 4000 RPMS WHILE THE CAR WILL TRY TO MAINTAIN SET SPEED (OFTEN GOES 3-4 MPH HIGHER). AS THE ROAD LEVELS, THE MOTOR WILL DROP DOWN TO NORMAL RPM'S. I ASKED THE TECH AT TOYOTA AND WAS TOLD HER HUSBAND'S COROLLA DOES THIS TOO. ACTED LIKE IT IS NORNAL.
