2019 Toyota RAV4

2019 Vehicle with less than 45K miles Got a message to take the car to the dealership. Dealership tells me that the coolant bypass valve needs to be replaced. Dealership representative tells me this is a common issue with cars like mine and the part is back ordered for an indeterminate amount of time. After doing some research, I see this is a major issue with quite a few Toyota models, not just Rav4.

The contact owns a 2019 Toyota Rav4. The contact stated that while driving at an undisclosed speed and attempting to adjust the front driver's side seat when the seat adjuster failed to operate as needed. The vehicle was taken to the dealer where it was diagnosed that the seat track assembly needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 35,000.

Warning Engine Maintenance light popped up on 2019 RAV4 Adventure, with notification to see dealership. Took vehicle in and was informed that the coolant bypass valve has internal circuit failure. Vehicle has has 23,000 miles, this should not be happening to a relatively new car. Appears to be a widespread defect per the Internet: [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

“Engine maintenance required - see dealer” message around 60k miles and subsequent coolant bypass valve issue should be a RECALL for 2019 RAV4s. Toyota either deliberately enabled this message to pop up to require vehicle owners to spend over $600 at Toyota dealerships, installed faulty coolant bypass valves, and/or failed to properly code messages in the vehicles. The message will not go away and requires only Toyota to disable it. Thousands of owners have had to take their vehicles into Toyota dealerships to correct the message and/or valve issue, costing at least $600. For these reasons, this should be a RECALL.

Toyota service bulletin: T-SB-0079-20 (August 14, 2020) Outer Rear View Mirror Image Vibration While Driving (Causes distraction and could lead to and accident because image in side mirrors are unusable due to vibration) Dealer refuses to do this repair because it was only covered under a 36mo or 36,000 mile warranty. My car currently has 23,500 and this repair should be covered...or be a recall! Some 2019 – 2020 model year RAV4 and RAV4 Hybrid vehicles may exhibit a vibration/shaking of the image shown in the outer rear view mirror(s) while driving. Mirror vibration can be observed at highway speeds of approximately 50 – 70 mph on typical concrete/asphalt road surfaces.

Engine maintenance required visit your dealer alert on screen. Seems to happen when the A/C is in use. Took it to a Toyota dealership for a diagnostic test and they said it was the Engine coolant bypass valve. The diagnostic test was $180. They mentioned the part was on backorder and I have been waiting for the part for a month now. The alert will not go away at all if the A/C is in use. The dealership mentioned this has been happening frequently with RAV 4s. It will cost approximately $771 to repair and $189 for a coolant flush.

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/
