About 3 years ago we started getting the red triangle of death with 2 amber lights on display the vsc and the round circle with the exclamation point in the center. This could happen in 500 miles or it could happen tomorrow. When this happens I loose all exceleration and air conditioning and a orange car emblem with an exclamation point in it on the display screen. Once safely off road press power button off and back on and everything is back to normal except red triangle and car on display screen car is then drivable again. Using a code reader to check codes no codes appear but still have red triangle. Leaving car set for a period of time and restarting car and red triangle is extinguished. Have to drive in right lane on freeway in case it wants to quit. The most recent time was last week had driven it about 80 miles with a stop about halfway for 1 hour and stopped for a movie came back got in car started it and within 1000 feet got the red triangle, was in left turning lane with red light, shut off and restarted and was able to drive again as in all other times, took it to a neighbor who had a code reader(about 9PM) and no codes found, he reset it and red triangle extinguished. This type of happening is very unnerving to say the least, dont know when or where it will lay down with us. Don't know if anyone else has had similar issues with their Prius ours has 213,000+ miles on it. Original hybrid battery it was checked in 2015 and some cells replaced by a shop certified to replace cells in this battery. Thank you.

Hello. My 2008 Toyota Prius had a malfunction with the "combination meter" which caused the vehicle dashboard to turn off completely, and we could not turn off the engine at times when stopped and parked. The dealer fixed the problem at a cost of $1580, and both the dealer and Toyota corporate through their brand engagement advocate acknowledged a long term problem with the combination meter. They had extended the warranty coverage for owners for this specific problem for about 10 years but not for owners like me with a vehicle 15 years old. I believe Toyota should cover and reimburse owners for this problem, which is potentially dangerous, no matter the age of the vehicle, especially for long term, loyal owners. There are many of these vehicles still on the road. Thank you. [XXX] [XXX] [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The dash lights on my car went completely blank and the car is unable to shut off. Toyota has a safety campaign that addresses this issue but it is only good for first 9 years of the car. My car is a 2008 model and I understand this problem affects all 2004-2009 models. As this is a safety concern with not being able to turn off the car properly, it is causing lots of anxiety not knowing if my car is actually turned off in my garage. My mom drives the car and she's 78 years old, she cannot tell if the car is off when she exits the car. There are occasions where the hybrid car turns on while it's in the garage because my mom was not able to turn the car off. This should be an issue where toyota issues a recall for the safety of everyone that owns these cars and parks in a garage.
