On 01/29/2025 at around 5:30pm I was driving home from work when suddenly the car stalled. I was going about 45 mph on a secondary to Lane Highway that was completely black because there are no street lights in that area. There were all kinds of warning lights flashing on the dash. I let my car drift to the shoulder was able to break and put it in park. I tried turning the vehicle back on but it would not start. My cell phone showed no Wi-Fi connection but I know the area very well and I knew I could walk several feet to a connection. Therefore spite concerns for my safety I had to leave my vehicle in order to call for help. I walked about 30 ft in the pitch black on this highway dressed in dark clothing on a shoulder that was very narrow. There was a pickup truck coming my way who flashed his high beams in my face but did not stop to see if he could help. Actually I was grateful for this because it's a pretty secluded area and I was very frightened for my safety. I was able to get a connection about 30 ft away from the vehicle and called my husband who said he would be on his way. I walked back to the vehicle got in and tried to start it. It would not start but all the warning lights were flashing on the dash. I decided I should take pictures of the warning lights in case we needed that for the dealer. After a couple of minutes I decided to try to start the car again and it did start. I was able to drive down the road to a Wi-Fi connection called my husband to let him know I was on my way. Once I got home the car seemed to be in order but there was one warning light telling us to take it to the dealer because there was something wrong with the hybrid system. We made an appointment to go in on January 31st. They inspected the vehicle to the tune of almost $200 and diagnosed the problem as follows: hybrid EV battery voltage system isolation internal internal electronic failure rear motor corrosion on both hybrid harnesses. Cost to repair $5,500.00

In September 2023 I kept getting a warning on my 2019 Toyota RAV4 saying “engine maintenance required”. My car had roughly 50,000 miles. I was not due for an oil change and I serviced my vehicle regularly. I tried to take it to autozone to read the code but nothing came up and they said I just needed an oil change which I knew wasn’t true. I finally took it to a local Toyota dealership on September 23, 2023 and the first thing the advisor said to me after I told her about the warning message was “I already know what’s wrong with it, you’re like the 4th car today with the same issue”. The issue was a defective coolant bypass valve. The advisor said the cars most affected were RAV4’s followed by corollas and it was happening at random mileages. I asked if there was a recall and there wasn’t, she advised me to call Toyota to make a complaint which I did and nothing happened. I had to pay around $1000 to get a defective part fixed that Toyota knew about and still hasn’t issued a recall. Theres a class action lawsuit currently involving 2019-2023 corollas and RAV4s, but I still don’t understand why there hasn’t been a recall. If I didn’t get it repaired, my engine could have overheated multiple times causing more issues. They are knowingly not recalling a defective piece of a equipment that has been installed in hundreds of thousands of cars.
