2019 Toyota RAV4

My car frame floods every time it rains. This flooding includes my sunroof drain clogging. As a result of the water retention in my car’s frame, my cars safety system controller units are being corroded and thus I DO NOT have any reliable safety monitoring system. I have looked into this and this a COMMON complaint for Toyota 2019-2021 Rav4 sunroof cars. I have had the sunroof drain cleared multiple times but the issue remains. So far it has impacted my tire pressure safety monitoring systems. This is a MAJOR safety issue as the electrical safety monitoring system controller units are NOT properly functioning as a result of poor water drainage.

Initially thought a seal on the windshield was faulty, so contacted the business who replaced the windshield. Business owner came to owner’s house Mon, Nov 4, 2024. He did a thorough inspection of all areas where water was identified by owner (dash, under the dash, on the driver side floor) and confirmed it was not the windshield. He then inspected the roof rack and determined the roof rack was defective and leaking water from the ceiling of the vehicle, down into the dash, and ultimately onto the floor. He recommended contacting Toyota because this was a known issue. By 12pm on Mon, Nov 4, 2024 owner contacted Toyota alerting them to the issue. An appointment was made to bring the vehicle in for inspection on Mon, Nov 11, 2024. Owners do not have a garage or carport, so a canopy was pitched over the car in an effort to prevent any further water damage and moisture absorbing canisters were placed in the car. The vehicle was not driven in the rain during the period after first noticing the leak and bringing it in to the dealership. Evidence of Electrical Damage: On Friday, November 1, 2024 the driver side seat became extremely hot, to the point of needing to pull over and turn the car off. The seat heater was not turned on at any point during this time. On Saturday, Nov 9, 2024 and Nov 11, 2024 while driving on the highway, the car (normally driven in Eco Mode) unexpectedly switched into Mud&Sand mode and all safety features switched off. Owner was unable to manually override this occurrence. The “Normal” button did not work. After a few minutes, the vehicle switched into the default setting and owner was able to put it back into Eco Mode. On Nov 11, 2024 owner brought vehicle into Toyota for diagnostics. Owner requested that the electrical components also be inspected and was told it was not covered under the Customer Support Program.

Defective coolant bypass valves on my 2019 Toyota RAV 4 have caused coolant to leak out of my vehicle’s closed-loop coolant system, harming its ability to properly regulate engine temperature. Eventually the message “Engine Maintenance Required Visit Your Dealer” appeared on my dashboard indicating an issue with the engine. An internet search of this error message on the 2019-2023 Toyota RAV4 and Corolla models shows this is a widespread defect, affecting hundreds of Toyota owners. A class action lawsuit has been filed against Toyota regarding defective coolant bypass valves in the 2019-2023 Toyota RAV4 and Corolla models [XXX] et al. v. Toyota Motor Sales, U.S.A., Inc) but Toyota has still not addressed this defect with a recall. Attached is a copy of the mechanic invoice I just paid to replace the defective coolant bypass valves on my 2019 RAV4 as the engine was not maintaining temperatures appropriately and in risk of total engine failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SUV showed on the display that there was a Hybrid System Malfunction. SUV is in a Toyota dealership shop in Aberdeen, WA. I called the shop immediately when the notification came up. Was advised that it was OK to drive until check engine light came on, which it didn't. I only drove to work amd back after the notification and call to shop. The cruise control would turn off and I'd be notified on the screen. Again was told ok to drive until check engine light came on. Approx a week after calling shop, SUV would not start before going to work. Had to be towed to shop. Potential safety issue if this happened while driving on highway or while in a rural/wooded/off main road area with no cell phone service. I was told my the shop that another SUV had recently had the same issue. Shop says that the wiring harness is exposed to the elements as built by Toyota. Has not been inspected by anyone but the Toyota dealership service dept. No warning ahead of time, just a notification while driving that there was a Hybrid System Malfunction amd then a Cruise Control Malfunction.

My rear backup camera has intermittently worked for almost 2 years now. I was not included in the recall Toyota K05 / NHTSA campaign number 19V576, but I do believe I should be included as the issue describes the issue I have been having. Dealer advised me I need a new camera but the camera works from time to time. The dealer could not replicate my issue in Oct 2023. I’m still having the issue and it has gotten worse.

“Engine maintenance required” maintenance light on dashboard. Very common issue within RAV4s. This message blocks the odometer on the dashboard when visible. It shows warning lights on the display as well. The part that needs replacing is a “coolant bypass valve”. My dealer wanted nearly $1000 to replace this part, and told me this part was on back order nationwide. My car begins to overheat after 1.5 hours of driving. The dealer said to pull over when operating my vehicle and it begins to overheat. This problem is an inconvenience as I commute to work in a busy city. This problem was first presented last week after my scheduled oil change with my local dealer. The next day (5/17/2024) the light came on my dashboard—unable to be removed. I first brought it into the dealer for a diagnostic on 5/20/2024, this is when they diagnosed a coolant bypass valve. I brought it back to the dealer today (5/23/2024) to have the part replaced, and was told it was on back order. I am afraid to operate my vehicle for long periods of time due to this issue. It has become a major inconvenience in my personal life this week, causing me to call out of work twice. This needs to be addressed by Toyota immediately.
