Three problems related to gas recirculation valve (egr valve) have been reported for the 2013 Toyota Prius. The most recently reported issues are listed below.
Loss of power, engine rattle at start. Toyota dealer inspected and said the head gasket is compromised. We have always take care and regular maintenance on the vehicle. I found out that Toyota has a fault egr system that is the source of the compromise. Toyota never notified us.
My Prius v recently started to have some issues with coolant loss and loss of performance. My onboard monitoring system (hum by verizon) warned me I have a misfire on cylinder 2. I replaced the spark plugs ( denso plugs) and checked all the coils. I also checked and cleaned the egr valve. This made no difference. Upon start up, there is a loud knocking noise and I have water periodically coming out of the tailpipe. I have taken my car to a reputable shop that specializes in asian cars and it has been diagnosed with a blown head gasket at 165,000 miles. Thats a very costly repair! I have looked at Prius forums and seems like this is not unusual for this year model. According to to people that are on this forum, Toyota has since corrected this problem. If this is true, shouldn't Toyota be responsible for damages? as a consumer and working man, is it fair that I bought this vehicle in good faith because of Toyotas reputation, only to find out that I have been deceived because they have been aware of this problem?.
On October 31, my wife and son were in the car approaching a parking space after completing a 360 degree turn into the parking space. Car suddenly accelerated and jumped a 7" high curb blowing out the right front tire and damaging the right rear tire. Car was towed to the team Toyota in glen mills who told me to notify Toyota of the incident. Toyota called me on November 2 and given a complete detailed account of the incident. On November 3, Toyota sent an authorization form to download the edr data which was returned along with diagrams of the incident. On November 4, bosch contacted me requesting the information already sent to Toyota which was sent to them. On November 22, the bosch representative went to the dealership and downloaded the edr data. On 11/26/16 - received report from eaa engineering analysis. Indicates that the car accelerated from 2. 5 mph to 7. 5 mph in 1. 8 sec. Accelerator depressed to 100% and at 98% at impact. There was no post crash information in the report . I have called Toyota three times since receiving the report and have not been able to speak with the case manager nor the claims department to date. They indicate that I won't hear anything until January 5. In the meantime I am driving a rental car.
