Hybrid Harness Malfunction. As reported on FaceBook by my wife to John Vitro of LIA Toyota: "Well my husband's RAV 4 wasn't safe and you knew it. And corporate knew it. You are in the business of saving lives by informing your customers when you find a defect in your cars. This faulty harness is dangerous. And the repair is costly and there aren't many of these parts available to make the repair. You put my husband and countless others in danger. Shame on you." Not only has the problem been confirmed: On May 11th, I received a letter from TOYOTA Motor Sales, USA, Inc. entitled, Certain 2019-2022 Model Year Rav4 Hybrid Vehicle (AWD Only) Coverage for High Voltage Floor Under Wire Harness and Rear Traction Motor Cable Corrosion CUSTOMER SUPPORT PROGRAM 22TE09 NOTIFICATION... There was a YouTube Video made by Bob Pellerin about this problem A YEAR AGO entitled, "CableGate, " AND an article at TorqueNews. (I have links if needed) The vehicle has been inspected and repaired by LIA Toyota in Rockland County. OVER $5,500 that I'm looking to get a FULL refund. LIA gave me back $1,000 for over-charging me. I want the FULL refund from Toyota Motor Sales, USA, Inc. A warning lamp/message appeared on May 6. I have emails, reports to corporate & screenshots of conversations with LIA service...all lasting almost 2 months. Toyota Motor Sales, USA, Inc. and LIA Toyota BOTH new of this problem a year ago BEFORE they sent out the letter. The letter states they would repair it for free if under 100,000 miles. I had 114,000, BUT...if I knew a year ago, I would have brought it in...UNDER the 100,000 miles, and got a FREE repair. Thank you for helping me get a full refund and for helping others with this same problem. USA Toyota owners NEED TO KNOW THIS!

Engine Maintenance Required light came on. Got it checked out by Toyota Dealer and the coolant bypass valve needs to be replaced. It seems to be a common problem with RAV4s.

The DATA COMMUNICATION MODULE - the DCM does not work properly. At first the Mic for the phone did not work when using the phone, then my clock and information page on the screen went in and out. I went to a dealership and they charged me $150 for diagnostic and now $1300 to fix. This is a vital piece of equipment for using communication devices hands-free. There is already a campaign to 21-22 RAV 4 models, and I believe this is the same issue only to the 2019 and 2020 also. Here is the link to the campaign. Please help me. https://www.toyoheadquarters.com/threads/2021%E2%80%932022-toyota-vehicles-dcm-data-communication-module-reprogramming-special-service-campaign-ssc-22tc01.2566/

Vehicle is switching to mud and sand mode on its own, which according to a quick google search is a common electrical problem. Possible cause listed by other drivers is a roof rail leak. Upon inspection I see water stains on the inside of my headliner where the roof rails sit. So confirmed roof rail leak. I have not yet had this looked at to learn the full extent of the damage.

- Rossville, IN, USA

Received multiple malfunction alerts. BSM & RCTW. Other safety features also inop. Dealership told me it was due to non-factory installed Cross Bars, faulty gasket allowed water into vehicle and flowed down onto the Engine Control Module. There was no way the amount of water said to have been in vehicle could have come from that 1 gasket, over 1" above roof. After $825+ and removal of cross bars water still leaking into car. Concerned issue will re-occur making safety features worthless, as well as damage side air-bags. These issues would all need to be corrected via out-of-pocket expense. Believe the issue is design flaw from Toyota.

- Wappingers Falls, NY, USA

Roof rack design and grommet failure allows for water to flow into cabin headliner and down a-pillars and other areas where curtain airbag and other electrical components are housed. This can cause malfunction and/or failure of the vehicles crucial functions at any given moment. A class action lawsuit is filed on this. You need to step in and make it a recall and hold toyota responsible.

Outside water (rain, carwash, etc) is leaking through the roof into the A-pillar and C-pillar areas and into the interior. Water is likely entering the air bag components in the front A-pillars on both sides, potentially causing a safety issue. Also concerned that water could be entering the electrical components in the dashboard. When researching the issue, found multiple complaints of this issue and also at least one class action lawsuit. Dealer is pushing back on covering this under the "Certified Pre-owned Comprehensive Warranty". https://www.carcomplaints.com/news/2023/toyota-rav4-roof-rail-leaks-class-action-lawsuit.shtml https://www.classaction.org/toyota-rav4-leaking-lawsuit https://www.motorbiscuit.com/lawsuit-alert-toyota-rav4-roof-leak-causes-water-damage-electronics-airbags/

Driving home from work on 3/25/23 at 9:15 pm my dash lights starting going on and off flicking. -??Power steering malfunction. Steering power low visit your dealer-?? -??abs-?? also multiple dash lights came on at the same time. Brake light steering light. Got home and took video while parked to safely show the issue

DCM unit failed. It controls Toyota safety connect and all communication to Toyota. If I were to be in an accident the SOS button to get help is inoperable. This has been reported to Toyota. This is a problem for nearly all the DCM units across the entire Toyota platform. Toyota is only willing to fix these defective DCM units under a 3 year 36k mile warranty. Considering the extent of the failure of these units across all their vehicles I believe Toyota should fix this systemic problem with their safety system outside their traditional warranty. Thanks

A couple of months ago, I noticed water had somehow entered the inside of my car, collecting along the interior roof panel and inside the C-pillar close to the top of the driver door. I did a little research to see if I could figure out what the cause of it was. I found that many other owners of 2019 and 2020 Rav4's had similar problems. Their findings indicated that Toyota had equipped poor quality gaskets, along the the area in which the roof rail trim were fastened to the roof of the car. I also read that this problem could be fixed by the owner, but was unaware that the water leakage would come in contact with electrical components. Yesterday, I experienced first hand the result of this situation. When starting my car, the display board was indicating a multitude of warnings for system malfunctions. These included power steering malfunction, brake system malfunction, pre-collision warning malfunction, lane-monitoring, and on top of this the RPM gauge and engine temperature gauge were both malfunctioning. These warning/indicators persistently flashed and caused a loud beeping sound to go off. The warnings also informed me to not drive the car and see a dealer immediately. After taking it to the dealer, the technicians were able to confirm that water has leaked through the roof rail panels from the area I previously specified. They found water on fuse box/junction connectors. They also found corrosion on pins on driver front door connector, under dash harness connector and body harness connector. While the water damage did not lead to a car accident, it did cause serious concern for the potential risk of car malfunctions. This information will be soon be reviewed by my insurance provider.

The engine on my Rav4 suddenly stopped without any notification while I was driving it on the freeway. I could have been severely injured from the risk of being rear ended by vehicles behind me. I have experienced this twice now, and both times, I have been on a busy highway in the middle of rush hour traffic. While driving, the engine would start sputtering and the vehicle will jolt and shake, eventually causing a warning message to appear that says power steering low, engine shutting off, place vehicle in Park. Then, when I turn the engine off, and try to restart it, it would flash a message that read Not ready to drive. After towing the vehicle to a service department, the vehicle would start up like normal, and the techs could not get vehicle to duplicate the issue. No codes would come up when they place it on a scanner, either. I researched the issue online, and it appears I am not the only one who has experienced this issue with the Rav4. Please reference https://www.rav4world.com/threads/engine-stopped-steering-power-low.323916/ This incident happened twice, once on 3/6 and again on 3/8. I thought the issue was fixed after having my vehicle towed on 3/6 to Freeman Toyota Service where they determined the issue was due to a recall on the fuel pump. However, the incident occurred again on 3/8, and I had to have the vehicle towed as the engine shut off while I was driving on the freeway blocking one lane of traffic on the interchange that connects one freeway to another. I was very fearful of other vehicles crashing into me as some of them were squeezing by between my vehicle and the retaining wall to get around me. It took the wrecker over an hour to get to me due to high traffic time. I have uploaded 2 tow bills I had to pay, and the service invoice for the recall work done. My vehicle is currently at another Toyota Service department where they are telling me they are unable to duplicate the issue.

Car randomly switches into different driving modes, BSM and anti collision goes off while driving. Seat warmers randomly come on high and can-€™t be turned off. Dealership identified water damage from leaking roof rack resulting in mold and electrical damage. Possible damage to airbags as water leaking into the pillar at front window. Many instances documented online.

I was recently driving my 2019 RAV4 when it started switching to mud and sand mode and turns of all my safety features. This would occur at random when I was parked and driving. I was able to find several discussion boards about this issue by searching -€˜ 2019 rav4 switching to mud and sand mode.-€ I took it to the dealership and they discovered that there is a leak from the roof racks that is causing water to get in my car and is now impacting the driving ability and safety features on this car. I was able to find many discussion boards and even YouTube videos on how to fix this issue by searching -€œ2019 rav4 roof rack leak.-€ It was reported in Australia, Japan, Taiwan, and the US. Many reported they had this issue fixed for free under warranty but now warranty has run out on the car and to fix the roof rack costs approximately $5000. Fixing the roof rack does not cover potential water damage that my airbags may have experienced as well and does not ensure there is not permanent water damage to the driving mode buttons

I have had my RAV 4 since it was brand new. Today while i was driving, the mud and sand screen popped up automatic with traction control light, later i was able to turn it to normal then the light would go off for a while and it comes back again. It all happened while i was driving in I 355 going down to Lemont, IL from Palatine IL. I had the same problem but not with the mud and sand but with snow back in 2019 when it was a brand new, took it to a dealership and they said they have never seen like this before and they just reset the computer and it went off. I am pretty sure when I first bought it, even i push each and every button of either snow, sports or mud, the traction light wouldn-€™t come off. While driving on i 355 today, my car slide for a while which was the most scary part, first I assume it was raining but after when the rain stopped too, it was skidding while applying the brake. I have the regular maintenance, just did the brakes with rotors, changed tires, oil change every 3-4k miles. I tried to talk to Toyota 800 number but wasn-€™t able to connect with them.

We have a 2019 RAV4 the mud and sand mode kept randomly turning on in the highway. The car loses traction when it goes into the mode. Toyota claimed they are not responsible. This is a very danger issue.
