Toyota RAV 4 vehicles prior to their 2023 versions are subject to CAN bus injection attacks resulting in the theft of the vehicle. I demand that Toyota provide the encryption fix to all previous years of vehicles and/or provide a physical method for protecting vulnerable spots where CAN bus attacks can occur. Methods like air gapping connections to devices accessible to the outside of the vehicle as well as better encryption for their keys.

I began having problems with my liftgate, i would press the button either in my vehicle or on top of the liftgate and it would only go up & down a little bit and stop. I took it to the dealer and was told the hinges are bad and I had to pay almost $500 to repair! Within a few days, I had the same issue again. After doing research I saw thousands of people complaining about the same issue and fee I completely wasted my money to the dealer as its worse then ever! Also, the several of the other owners of these vehicles are stating that after they paid to repair the hinges and took vehicles back to dealer, they are being told the need a motor and thats about $3500! I would love to see a recall as I am far form the only person with this issue, I will also be calling Toyota Customer Care as I will request a fix again or a complete refund. Thank you Please contact me if you have any questions.

Coolant bypass value failure 1000$ to replace on a vehicle that’s only a few years old Toyota refuses to fix it

My name is [XXX] and I would like to file a complaint against Toyota. I purchased my RAV4 XLE in 2020 after returning home from military training. This was my dream car and I was filled with joy to be able to purchase it. In the four years I have had it, I have had minimal issues, nothing to note other than normal wear and tear, until recently. The "Engine Maintenance Required" light came on roughly 3 weeks ago. I deemed it to be my oil change notification and reset it knowing when my next oil change was due. The notification came back on to which I started investigating further. I typed in "2020 RAV4 Engine Maintenance Required" into Google and was surprised at how many car forums and complaints popped up for this exact problem. It was an astronomical number of complaints made by loyal Toyota owners. I scrolled for an hour reading everyone's story, which was almost identical to mine. I made an appointment at my nearest Toyota in Bountiful, UT to get a diagnostic test done. Not to my surprise, the code that was tripping the system was for the 'coolant bypass valve.' I was quoted $660 for the parts and labor. After getting a price breakdown and verbally stating how frustrated I was with this issue due to how many others online had the same issue and there not being a recall, I felt like my only option was to pay it and suppress my anger. I am not upset with the Toyota dealership I went to. I am upset that this is a very known issue that even the mechanic verbally stated knowing about, and that Toyota as a large corporation is not doing right by the people who swear by owning Toyota's and their reputable reputation. I called two private mechanics about the issue and they both stated that they have worked on several RAV4's with this issue. It is not cosmetic, it is a critical issue that needs to be fixed. I hope this complaint makes it to the right hands and a solution is implemented so people can enjoy their car without these worries. Thank you.
