2020 Toyota RAV4

The wiring harness to the lithium battery is corroded, and it is unregulated. My repair shop said the car is unsafe to drive because of the amount of unregulated electricity in the battery. Also, the cruise control doesn't work. My repair shop says this is happening to other vehicles. Parts and labor total almost $7,000.

I was making a turn into a turnaround on the turnpike and ended up sliding into a guardrail. I believe the brake assistance failed because although I slowed down and braked going into the turned, the vehicle felt like it had lost control and continued towards the guardrail rather than into the pathway I was turning into. My safety was at risk from going into the guardrail when my car didn't slow down as much as I would have expected. As of now, a braking problem with 2020 RAV4's has not been confirmed by Toyota but they are set to inspect the facility within the next couple weeks to collect information from the Event Data Recorder. It's currently at a State Farm holding facility. There were no messages or symptoms of this issue prior to the incident.

On or about 8/21/23, we were driving from Vermont back to our home in New Jersey when the sound system started malfunctioning. First, we lost all sound (safety warnings, as well as radio). The sound returned and then cut out again repeatedly. Then, the speakers emitted loud (full volume) static and popping sounds despite the audio system being "off." At the time, we were driving at approximately 65 mph on a highway with our two young children. The noise was so loud that it was difficult to focus on driving. The static and popping sounds continued until we pulled over and shut the car off. These failures have continued and increased in frequency since that time. Our safety was put at risk in two ways: 1) all of the safety warnings were and are muted and ineffective and 2) a full-volume static/popping sound while driving at highway speeds could have caused an accident. Subsequently, we did the following: -Googled the issue and found a relevant Technical Service Bulletin published by Toyota in September 2020 that applies to our make/model and VIN. It is labeled T-SB-0086-20 and can be found here: [XXX] . This suggests the issue applies to multiple Toyotas. The Bulletin indicates the VIN number where the issued stopped -- suggesting Toyota took steps to fix it. There has been no recall related to this issue and we were never notified of this issue. The issue is apparently related to a defective amplifier. -Brought our vehicle to our local Toyota service center (Paul Miller Toyota of West Caldwell NJ). An employee there was able to reproduce and confirm the issue and recommended replacing the amplifier. -Called Toyota to report the problem and register a complaint given the safety issues, failure to notify us of the problem even though it was known to Toyota, and the cost of repair ($2640). There were no warnings, messages, or other symptoms of the problem prior to the failure on or about 8/21/23. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On several occaisions the vehicle has incorrectly detected an impending collision, disconnected the adaptive speed control and applied the brakes forcefully. On one occasion, it happened while driving in heavy slushy snow. Speed control wouldn't reengage. The dealer suggested cleaning off the Toyota logo in front and that resolved the problem. The other times the problem occured, the vehicle was being drive in late afternoon daylight on I 80. The vehicle was in the left lane, going around a tight (for an Interstate) curve with another vehicle in the right lane and slightly ahead. It apparently thought that the other vehicle was in the same lane. i.e., the vehicle had inadequate knowledge of it's position relative to the roadway. Up to that point, it understood that it was in it's own lane. Each time this occurred, the road was (fortunately) relatively empty so no crash occurred.

I was driving on an Interstate highway with th speed control on in extremely light traffic and very heavy, slushy snow when the brakes were applied full and the instrument panel flashed red. There were (fortunately) no other vehicles in front or behind me. Since there was no reason for stopping, I stepped on the accelerator and the vehicle operated normally EXCEPT that I was no longer able to use the speed control. Calls to Toyota's 800 number were of no help, but a service advisor at Sunrise Toyota suggested cleaning slush off the Toyota logo on the grill. After cleaning the logo, the car operated normally. Toyota subsequently examined the car at the dealer and determined that it was operating as designed. I BELIEVE THAT THE VEHICLE'S SOFTWARE DESIGN IS DEFECTIVE AND MUST BE REDESIGNED.

I bumped the car in front of me when starting from a red light at an intersection. Impact speed was less than 3 MPH. The damage from this impact resulted in repair cost of almost $4,200. This is outrageous and an example of poor design on the part of Toyota. It is my understanding that the standards require vehicles to absorb up to 5 MPH frontal impact with no damage. Had I known this vehicle was so poorly protected I would have chosen to purchase something else.

A FEW MONTHS AFTER I PURCHASED MY 2020 RAV4 XLE HYBRID, I NOTICED THAT MY BRAKES SQUEAKS WHENEVER I MAKE A QUICK STOP, OR AFTER I RELEASE THE BRAKES AFTER STOPPING OR WHEN I AM BACKING UP. IT DOESN'T MATTER ON THE KIND OF ROAD THAT I AM ON. I BROUGHT MY CAR TO THE DEALERSHIP AND THEY SAID THAT IT IS NORMAL FOR A HYBRID TO SQUEAKS DUE TO THE BREAK ACTUATOR. I KNOW PEOPLE WITH TOYOTA HYBRIDS AND THEY DO NOT HAVE THIS PROBLEM. I AM CONCERNED BECAUSE THIS COULD BE A DANGEROUS ISSUE. PLEASE ADVISE. THANK YOU

THE TOYOTA ADAPTIVE CRUISE CONTROL KEEPS A SAFE DISTANCE TO THE VEHICLE IN FRONT, SLOWING AND ACCELERATING PROPERLY TO KEEP A SET DISTANCE EVEN DOWN TO A FULL STOP. HOWEVER, WHEN TRAVELING AT ANY SPEED AND ANOTHER CAR ENTERS MY LANE IMMEDIATELY IN FRONT OF MY VEHICLE THE SYSTEM DOES NOT RECOGNIZE THE NEW VEHICLE AND HOW CLOSE IT IS TO THE FRONT OF MY VEHICLE. IT DOES NOT SLOW AT ALL EVEN IF THE DISTANCE TO THE INTRUDER IS ONLY A CAR LENGTH OR LESS. I HAVE TO MANUALLY BRAKE QUICKLY TO PREVENT FOLLOWING TO CLOSE AND CAUSING A POSSIBLE REAR END COLLISION. THIS HAPPENS EVERY TIME A CAR SQUEEZES IN FROM OF ME WITH THE ADAPTIVE CRUSE ON AND IS VERY REPEATABLE. I'VE EXPERIENCED IT IN ANOTHER NEW RAV 4 TOO. THIS HAS BEEN REPEATABLY GOING ON SINCE THE VEHICLE WAS PURCHASED NEW ON JAN, 2020
