“My coolant inverter pump has been recalled, and repaired before I bought the car, and the same issue is happening again after I bought the car less than a year ago. Today, the same check engine light came on, went to advanced auto parts and got the code p0a93 - coolant inverter pump failing.”
NHTSA complaint #11343344, filed 2020-08, 103,320 miles“I have three major problems with my 2008 Prius. #1 the engine intermittently, will not turn off when parking the car. #2 the dash lights also intermittently will not come on, affecting my ability to see how fast I am going on the highway or streets, it also prevents me from seeing how much gas is left in the tank. #3 the outside air and air conditioner, also will not work, intermittently.”
NHTSA complaint #11063356, filed 2018-01, 106,000 miles“At 93,000 miles my 2008 Toyota Prius began rapidly consuming oil. I was told by dealer that nothing could be done and I needed to carry oil with me and check level every time I fill up my gas tank. This is a known issue with the Toyota Prius according to my dealer and web research.”
NHTSA complaint #10898678, filed 2016-08, 93,000 miles“Cluster went blank and vehicle would not power off, key fob stuck in ignition.

NHTSA complaint #10937659, filed 2016-12, 69,359 miles“I was driving my 2008 Prius on highway and warning light came on. In 2 minutes all power gone and I have had to towed to the dealer. They said, water pump failed and because of that hybrid inverter fried. Car was out of guaranty and there was no recall about water pump. I paid nearly $5.000.00 for water pump and hybrid invertor. I have seen there is a recall about water pump now. Is there any way I can get my money back?”
