I was sitting idle in my car. The two cars crashing icon came on even though I was in the parking lot doing nothing. There was also issues with the other indications where I would use the back arrow on my steering wheel to clear the issue and it would not clear. Seems unsafe and scary.

What owners actually said
185 reportsAt 61,000 miles I got an engine maintenance required light. After doing research on the Internet, I see that many people with the corolla similar years have had this issue. It is an engine coolant bypass valve.
Coolant bypass valve needs replaced. Car states 'engine maintenance required visit dealer.'
See attached document for complaint.

I have been taking my Toyota to Sun Toyota for routine maintenance and inspections. Upon today’s inspections they are claiming the battery looks like it leaked on the axial, some of the undercarriage components look broken and rusty. Possibly needing replacement. The overall car is less than 60k in mileage so that seems odd to me. I also brought the car in at 45k and they made no mention of these issues during that vehicle inspection. I asked about my brakes and braking issues. I do not slam on my brakes and the technician said I should stop braking too hard. There is noticeable wear now on them. I asked them to change them at the previous visit and they refused saying it did not need it. I am concerned for my safety and lack of care at this sun Toyota.
Yes the car can be inspected. Yes took to dealership today and they don’t know what’s causing it but what between $855 - 1,100 to fix. When it rains the front wipers automatically come on as they should. Then without warning, they stop working and on three occasions a wiper flew off and my teenager had to stop and run into mi…

Yes the car can be inspected. Yes took to dealership today and they don’t know what’s causing it but what between $855 - 1,100 to fix. When it rains the front wipers automatically come on as they should. Then without warning, they stop working and on three occasions a wiper flew off and my teenager had to stop and run into middle of road to get the wiper. She was on a rural highway and could not see well without the wipers working. I replaced the wipers, but when it down poured rain again, like before they just stopped working with no warning. She had to drive 25 mph on a road that was ranges 45 -55 mph. She had a very hard time seeing and could have wrecked. This could have caused an accident had she been on the freeway going 70 mph. A Google search shows others have experienced this issue with their car. The only person who has inspected the issue / car is the Toyota dealership today. They said they don’t know what’s causing it and would cost more money to try and diagnose, but they said it appears if you run the wipers at the very slowest speed it does not malfunction. I don’t have the money to fix it right now, so we are going to try and not drive in rain and if caught in a storm while driving, like before, we will try running wipers at lowest speed as they suggested. First incident was April or May 2024. Most recent incident was July 2024. Sorry I don’t have exact dates.

Coolant bypass Valve
Engine code P2681(15) which after lookup is the coolant bypass valve which is a common faulty part that Toyota seems to not care about and charge upwards of 700$ at the dealer to fix. I took the part out and it indeed has a crack around the case

My car reached 52,254 miles and I got a engine maintenance required a scary message I have never seen before I thought it was the oil maintenance one but it’s not I keep dismissing the message because I can’t see my speed and it stays in the way I have realized that if I start the car with AC on the message pops up but if I don’t have ac on and start the car it never appears unless I turn on the ac as the car is already on so it seems to be the coolant valve bypass I received the error message as I was parked for no longer than 40 seconds at most
