I bought the 2020 Rav4 XLE back in 2019 and had driven for four and half years now. I went to the dealership to get my routine oil change just this Monday July 29th 2024. As usual, the dealership did multi-inspection on my Rav4 and didn't find any problem that requires immediate attention. Two days later, a warning message popped up on the MID screen right after I started the car and read "Engine Maintenance Required". After searching online, calling both local mechanic and Toyota dealership, it happens to be a well-known issue for many 2019-2023 Toyota models including Rav4, Camry, Corolla that the faulty coolant bypass valve has to be replaced. …
Wire harness failure according to the Toyota dealership representative I spoke with after inspection on 12/18/24. Rep said this is a known issue with certain years and they will cover cost of replacement. Previously, I had received a message stating, "Hybrid System Malfunction, Visit your Dealer" but could not get an appointment until 12/18. The dealer rep said they needed to order parts to fix the wire harness issue and that I would be okay taking the car and bringing it back when parts were in. The day after the inspection (12/19) I was in a Walmart parking lot and my car started but I could not get it to drive or reverse. A message stated "Vehicle not ready to drive" and "No power to rear brakes". If I put the car into drive or reverse and stepped on the gas, the car interior lit up and the dinging sound (usually associated with unbuckled safety belt) was heard. …
-Inspection found coolant bypass valve seized recommendation, was to replace coolant hose with bypass valve. YES, the car is available for inspection upon any request -Safety risk unknown if not fixed -Michaels Toyota of Bellevue Washington confirmed on September 23rd 2023. I brought the car in originally on September 9th 2023 for a 10,000 mileage service and oil change. when I called to ask why the engine maintenance notice wouldn't turn off. I was scheduled to bring the car back on September 23, 2023 the needed part was not in stock nor covered by the factory or powertrain warranty with 31,2002 miles on it. The warning light came on at the same time the service and oil change was due. I was stopped a month prior by a random mechanic who noticed the car was leaking abnormal amounts of what he said could be coolant on the passengers front undercarriage. …
My Toyota 2020 RAV4 has a dangerous design flaw. It rolls when turned off and in drive mode. For example, my driveway is on an incline, and a couple times I have pulled into my driveway, gotten distracted, and I forgot to put the car in Park. When I hit the on/off button, the car rolls backwards, accelerating due to gravity. If you're not quick, you can end up rolling out into traffic, or running someone over that is behind your car. All the other cars I've ever owned didn't roll when the car was turned off unless you were in neutral. I believe this is a design flaw because I've spoken to a few other RAV4 owners that have experienced the same thing, and on one occasion, I tested it on another RAV4 and it was the same. I can see this being very dangerous. …
Got an oil change Monday 8/7/23 When I left the dealership & arrived home the "engine maintenance required" light came on. Contacted dealership next day (service was done at Maita Toyota of Sacramento) let them know about what happened they told me they'd do a diagnostic on the vehicle. Car was at 43,772 miles when I dropped it back off at dealership. They ended up letting me know the diagnosis was the coolant by pass value / hoses were bad and needed to be replaced. However - Toyota would not cover the repair because of their current powertrain warranty expiring on my vehicle. After researching online this seems to be a common issue with this year of rav4. I was luck enough to have extended warranty and only had to pay a $200 deductible but had I not it would be been almost $800 I would have had to pay. Toyota should be made aware of this issue. …
During summer 2026 i began to notice a noise/whine above 30mph that would only occur when foot is on accelerator. my vehicle has 83k miles on it (me being only owner with routine maintenance). as a responsible owner, i had my dealer do an inspection. after a drive and a listen, they claimed it was a transmission bearing failure and only solution is a $11k transmission replacement, with the commentary "we had a camry in last week with same issue". Being responsible owner, i got a second opinion from an independent shop who also verified "transmission bearing failure, you will need a new transmission. currently the part is on backorder because so many are needing to be replaced and no one should do a replacement with a used transmission". This is not the quality i expected out of toyota -- transmissions should not be needing to be replaced at 83k miles.
My 2020 Rav4 Limited AWD alerted me that the engine needed maintenance, and, so I parted it until Tuesday, After talking to the service professional at Passport Toyota, they told me about everything else but did not see that the light was on. They did my regular 55,000 miles maintenance on my car. So before driving away, I noticed that the alert was still blinking on my car. Their findings is that the coolant bypass valve/hose etc., has gone bad and is remaining in the open position. Apparently, this part isn't covered by warranty. After reading, there are a lot of years such as 2019, 2018 to name a few having had the same problem. And to fix the problem it is $857.22. Since this problem is occurring in a lot of Rav4's, and I noticed Camry's as well, should they look into why this is happening in a lot of models of their cars, SUV's etc.
The Coolant Bypass Valve failed for my RAV4 at 59,210 miles. This was confirmed to me by Hoover Toyota. The part has not been inspected by the manufacture, police, insurance representatives, or any others. I had a message appear at 59,202 miles on my dashboard screen that said, "Engine Maintenance Required." I have already gotten Hoover Toyota to fix my part. My concern comes in part that reading through online forums, it appears this is a very regular/common problem for RAV4s (2019-2022) and seems to happen between 45,000 - 65,000 miles. If this is a known issue, I am curious as to why Toyota has not recalled this part since you wouldn't expect a car under 5 years old and driven less than 100,000 miles to have this kind of problem.
