Check Engine Light On Problems of Toyota Prius - part 1

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.

Driving on a highway on my way to work suddenly the my 2013 Prius c engine completely stops. The check engine light and check hybrid system light came on. The car completely shuts down and now I'm a sitting duck good thing people slew down for me and even help me push my car to the side of the road safely. This is a very dangerous situation and needs attention. Ived taken my car to antioch Toyota and emphasize that I saw 2 recalls on this website but the did not believe me and they are charging me over $4000 to fix it. It's not right for them to just check their system and not check a NHTSA website for recalls and complaints. It's very irresponsible for them not to check for recalls.

I am the first owner of this vehicle it has about 110k miles recently the started to shake when I start it in the morning or when parked for a while it started to show the check engine light some time it goes away on its own so I figured I will do 100k service changed the spark plugs oil filter etc. The shaking went away but after 1k miles the symptom came back with service engine soon and check engine when I scan it the code read p0301 I have also noticed the coolant is low went Toyota picked up a coolant and added about a quart then the problem still persisted when I went online for an answer I was surprised by what I discovered most of the cars with the same problem needed an new or rebuild engine as long time Toyota fan owned many different ones I was baffled by this problem I need help. As I learned online this problem affects most of gen 3 Prius at this point I don't know what to do except ask Toyota for repair or replacement of the engine as I just finished paying for it. The problem happens only when the engine is running at stop or driven at low speed I have also notice the average gas milage suffurs. When the car is accelerating the problem seems be unnoticeable.

When driving at higher speeds than 40 mph, my check engine light, and check my hybrid system light is turned on. When it turned on, I was unable to accelerate, however I was able to pull over, and restart my car. I have recently come in to get a software update for the factory recall related to the issue. However my inverter has been damaged as well. On this website it states if my inverter is damaged related to the recall, it will be repaired free of charge. However the Toyota dealership charged me for diagnostic, and requested payment for the replacement of my inverter. I also have given Toyota a call as well, they have stated that the recall only will consist of a software update. I was unable to get anyone from Toyota to help me with my repair of my inverter thus far.

While driving at CA freeway speed (65mph) the car goes limp. The accelerator fails to work and even flooring the vehicle makes no difference. At this point the speed of the vehicle decreases and I have to immediately pull to the shoulder. The "check hybrid system" alert shows on the dash and also electric power steering and check engine light. This issue has been going on for the past year and I have taken it to several Toyota dealerships with no resolve. I have spent a total of $4500 without Toyota of vallejo or the now bankrupt Toyota of fairfield solving the issue. This is a life threatening issue and happened several times with children in the vehicle. . Read more...

Engine misfiring at start. While at intersection in city and turning left, accelerating and triggering the combustion engine, misfiring causing jerking and lack of acceleration almost causing a stalled car in oncoming traffic. Check engine light on. Service says misfiring caused by faulty head gasket. Appears to be symptomatic of gen 3 Prius.

Went in to have the spark plugs and 2 coils(cylinders 1 & 2) started shaking, knocking and smoking at the time I picked it up. Check engine light is on and hasn't gone off. The mechanic I take the vehicle to says it is a problem with this model car, trying to determine this, since he stated it is now my head gasket that needs replacing.

My car recently has a check engine light and the obdii scanner show the fault code p1121 which is a failed three-way coolant control valve. Toyota has issued a technical service bulletin (TSB) on this problem: eg001-08 m. I. L. It should be a recall because it's a common problem for 2nd generation Toyota Prius.

The contact owns a 2006 Toyota Prius. While driving 20 mph, the check engine warning light illuminated and the vehicle stalled. The contact was able to restart the vehicle; however, the failure recurred six times. The vehicle was not taken to be diagnosed nor repaired. The vehicle was not included in NHTSA campaign number: 12v536000 (engine and engine cooling, hybrid propulsion system). The manufacturer was not notified of the failure. The failure mileage was 106,082.

When my 2009 Toyota Prius reached approximately 65,000 miles, the check engine light came on, and the error code was p1121, indicating a problem with the coolant control valve. I took the car to my local Toyota dealership, and their charge for replacing the part was $400. The mechanic who inspected the valve said it was not closing securely. He said making the repair would not improve the car's performance or affect its value, and therefore he did not recommend making the repair. Unfortunately, I have realized that opting out of this repair does affect the car's safety. The check engine light is constantly on. Even if I manually turn it off, it comes right back on, so it is unlikely that I will be aware if other mechanical issues ever arise. My mother drives a 2008 Toyota Prius which just hit 65,000 miles, and her car produced the exact same error code. It is statistically impossible that two cars of the same make and model, only a year apart in age, in the same household, would produce identical error codes after reaching roughly the same mileage for any reason other than defective manufacturing. I believe this error code is the result of a manufacturing error that Toyota should address through a safety recall. Toyota's own mechanic admitted that the repair is financially impractical for customers, yet if the repair is not made, drivers are left without a functional check engine light which is a safety hazard.

Was driving to nova scotia 10/18/13. Stopped for coffee after 2 hrs of driving. Car would not restart. Returning to maine10/20/2013 was passing a tractor trailer truck with another trailer truck passing behind me as well. No check engine light had come on at any time during the trip. Suddenly,all the warning lights on the dashboard lit up and the car stopped working while driving at 75 mph. Tried not to slow too quickly with truck bearing down behind me ,but could not accelerate either. Car had popped into neutral . Got off on left of two lane highway . Car was dead. Would not start. Had towed to Toyota dealer in amherst. Diagnostics found no cause. Had to drive 4 hours back home next day not knowing if it would happen again. Took car to Toyota dealer 45 miles from my home in us. The following week . No cause found. Happened again shortly after on main street, blocking traffic . Towed to local mechanic. Was there one week. Unable to diagnose. Towed 45 miles to Toyota again. There another week. I was told it was a problem with fuse box assembly. Shortly after, the master warning light came on, as well as a warning symbol on the touch screen meaning 'malfunction in hybrid system. ' towed again to Toyota dealer. Front battery replaced. Noted today that Prius recall on '09-'14 models for exact same thing that happened to my '08 model. Total cost $600. 00 plus $270. 00 towing and $120. 00 for hotel .

Master warning light came on along with vehicle stability control, brake & check engine lights. Took it to my Toyota dealer (rice Toyota, greensboro, nc). I work 79 miles from home. I called my Toyota dealer, a service rep said it was ok to drive as long as the warning lights weren't flashing. Diagnostic codes indicated the hybrid converter/inverter was bad, they cleared warning lights, which stayed off. They said it may have been a "glitch", if warning lights returned, bring it back. They returned on 3/1/13 while driving to work. I lost power while on I-540, pulled over onto shoulder, turned off engine, restarted it, got back onto I-540 & exited at nearest exit. Lost power again. Pulled over, went thru stop/start process, drove 3 miles to work. Drove home with warning lights but no power losses. Took it to rice Toyota next morning. This occurred barely 2 weeks after the 100,000 mile powertrain warranty expired, galling to say the least, as this part "is" the hybrid system per the service rep. Have you received other complaints about this component?.

While making a u turn the vehicle lost power and the check hybrid system warning illuminated. The car died in the middle of the road. The dealer claimed that there was oil in the throttle body caused by overfilling and this is a common occurrence with oil overfills on Prius vehicles. The last oil change had been 8,000 miles and more than 2 months previous. The place that performed the oil change agreed to look at car and clean the throttle body. They also checked the oil and made sure it was correct level. Three weeks later the same thing occurred. This time the car lost power and the check engine light illuminated. The car died on a freeway transition over pass and we were stranded on the freeway in a very dangerous situation. The car was towed to another Toyota dealer and they claimed it was the same thing. The oil change place says absolutely no way is this the problem since they looked at it very closely the last time. I requested Toyota to send out a field representative to confirm that this was the cause. They refused. Computer codes p3190 and p0a0f hv.

2008 Toyota Prius. Consumer writes in regards to defective parts replaced in vehicle. The consumer stated the check engine light illuminated. After doing research, it appeared the problem was with the coolant control valve. The vehicle was taken to the dealership, where an inspection revealed the check engine light was due to the premature failure of the coolant control valve.

While driving on the highway at 70 mph, the following symptoms occurred on my 2005 Toyota Prius: (1) car would not accelerate, (2) engine light came on, (3) problem light came on, (4) battery went red, (5) car stalled and would not accelerate/drive any further. After turning off the car and restarting it, I was able to drive it back and the battery recharged itself to green. After taking it to the dealership and having this problem "fixed", the exact same situation happened two more times, again 6 months later and then 2 weeks after that. The second time I was driving again on the highway at 70 mph, the third time I was driving at night at 40 mph.

I was driving on the highway when my vehicle's check engine light came on. Shortly after I saw a large amount of smoke coming from the engine. I pulled over and shut off the car. Car smelled like burned plastic and smoke. I was worried that the car could catch on fire or blow up! I had the car towed to my nearest Toyota dealership. Toyota claimed that the three way coolant control valve had failed and the steam came from a ruptured line in the coolant system. The job cost me $422. 32. I didn't mind paying the service but after careful research into the problem with the 3-way control valve on the Prius I had learned that this is a wide spread problem. Apparently the valve tends to stick causing no flow of the coolant fluid. I feel Toyota should fix this problem before someone gets hurt either by getting burned from a ruptured line or the car catches on fire.

My 4 year old Toyota Prius lost engine power on the freeway on two separate occasions. Driving in stop and go traffic on freeway I heard one beep as the car lost engine power slowed down and went to battery. A long row of warning symbols, starting with the triangle, lit up. I slowly exited freeway on battery power then turned car off. I restarted car about 15 min. Later and engine started, only warning lights illuminated were red triangle and check engine light. Dealer replaced inverter pump assembly and flushed the inverter system. 5 days after repair, while exiting freeway during normal traffic, beep sounded and engine shut off and the above order of events happened again. This time dealer replaced inverter assy (assembly?).

We bought the Prius on June 2008 and it has only 4023 miles but in last one month it broke down three times . First time the car stopped on highway a strong beep sound and then check engine light, vehicle stability control light and a big red alert triangle came up the car lost it's power completely and got stalled in the middle of hwy - pretty scary. Then on 6/2/2009 we noticed that we cannot open the hatch back door and the car is completely dead. Both times we towed the car to the dealer and first time they said they did not find any thing wrong and they have reset all the computer, second time they said the battery was drained out without really NY proper reason. Last night we drove the car may be about 15 miles or so and it's the same situation the beep sound and all the hazard lights came on in the middle of the road and the car is dead again and we had to tow to the dealer. Three times in one month and in the middle of the road with a $30,000 dollars car is unacceptable. Some one really can kill us from the back because it is so sudden that no way they could predict that we are going to be stalled within 5 seconds from 65 miles/hour speed. We have a child and she travels on the back seat all the time. What is the solution for it? Toyota needs to take the responsibility. It is a real safety issue for our family.

The check engine light on my car came on and the engine stalled. The car had to be towed to the dealer. The car was repaired at a cost to me of $1100. The throttle body had to be replace, and also the ecm. The car only has 75000 miles.

Prius stalled when pulling into traffic from a stop light. All lights on the dash board were illuminated including the check engine light. Only electric drive systems was operational. I immediately pulled into a parking lot and turned the car off. Upon restart, only the check engine light was on. Was able to drive to the dealership 2 miles away. Stored error code p0a7a was identified - bulletin eg029-05. "false m. I. L. "on" condition. An updated control ecu was installed, covered by warranty.

I was transitioning between two freeways in my 2004 Toyota Prius and had started braking/decelerating for a looming traffic jam up ahead when the gas engine stalled and all dash warning lights came on, along with the nav system screen saying "problem" and a red car icon. My speed could have been anywhere between 70mph and 35mph at the time of the stall. The electric motor was still functional, so I exited the freeway, parked the car, powered it off, then powered it back on. The red triangle of death was still lit on the dash, as well as the engine check light, but the gas engine was now operating normally and was recharging the almost-depleted electric drive battery. I was able to drive home without any further incident. The next day, I took my car into Toyota of huntington beach for repair, and they "reprogrammed [the] electronic control module". My symptoms seem related to the pe05029 defect investigation and the NHTSA odi complaints of other Prius drivers. This desperately needs to be a recall item because a sudden deceleration to 40mph on a freely moving freeway with other traffic traveling at 75mph could be a very dangerous rear-end collision risk.

2004 Toyota Prius. While driving 55-60 mph vehicle constantly lost power. The engine check light came on. The consumer had difficulty restarting the vehicle.

I was driving my Toyota Prius on the freeway and the vehicle died at 55 mph. The engine light illuminated and there was no power to the accelerator. Fortunately, traffic was light and I was able to coast to a secure spot on the side of the road. This happened on the approach to the bay bridge, which would have been a potential disaster had it died on the bridge itself. The car did not start again on my first attempt, but it did start 5 minutes later. I took the car to the Toyota dealer and they said they installed new information into the computer. I want to know why, if they know it needs new information, did I not receive a letter asking me to come in for service? this could have been really disastrous, and I fear that it will be for someone else.

For the second time my 2004 Prius has stalled while driving and shut down. I have attached my previous report to you when it happed in may 2005. The first time the ecu was reprogramed. This time I was driving on the freeway going 65 miles per hour on July 2, 2005 when the emergency engine lights came on on the dash board. The vehicle quickly loss power before the engine shut down. The battery meter confirmed the loss of reserve. I had the vehicle towed approximately 50 miles to maita Toyota where I have my Prius service. The vehicle was keep from July 2 - 12, 2005. The service department was not able to identify the problem. I picked up the vehicle and drove it home today. Now I have to watch for the next time that it happens for Toyota to research the problem more. A file was open with Toyota #2005 00071145 but without any help to identify the problem.

Driving 65 mph on the freeway, the low-fuel indicator light started blinking. Approximately 15 miles later, still driving 65 mph, the engine shut off. Dashboard warning light and check engine light illuminated. "consumption" was highlighted in red. The car continued to drive in electric mode at 52 mph for about 1. 5 miles. When the battery was drained, the car came to a stop. After 5 minutes, I hit the power button to turn off the car, then again to turn on the car. The engine started and we drove to the next gas station, 4 miles away. Toyota (1-800-331-4331) said to take it to the dealer. The Toyota dealer said there is nothing they can do and Toyota has not advised them on a remedy. Dealer refused to provide me with this agency's name (NHTSA). I left a message with "the Prius team" at Toyota 3 days ago and they have not returned my call.

I purchased a 2005 Prius in January 2005. At the time of the incident it had about 8500 miles on it. It had been performing well and I had been getting excellent gas mileage and the internal mileage indicators has proven to be very accurate. While driving on SC highway 31 at about 60-65 miles per hour the gasoline engine quit slowing me to about 40 miles per hour. The dashboard lit up with with warning signals including the red triangle, check engine, vsc, breaking system and I don't remember what else. A few miles before this happened, my fuel indicator started to blink, but was sure that the problem could not be gas since I have often gone many miles before finding gas in similar situation and knew from past experience, my milege,and fuel usage indicator that I had about two gallons left in the vehicle. This was an unfamiliar road to me so I continued to travel using the battery hoping that an exit would appear. The battery quickly became so depleted that I pulled to the side of the road. I tried to turn the vehicle off and found it unresponsive. After a few tries it did power down. I called aaa for assistance. During my wait, I was able to restart the engine, but it again failed within a couple of miles, but I was able to reach an exit and pull off. After the second failure, I tried to restart again and this time only got the red triangle and check engine light. Aaa did add gasoline to the car, but the fuel indicator continued to blink and the bar never rose. The car was towed to sparks Toyota in myrtle beach, SC who called to say that they believe that the problem is low fuel. I do not believe that it the case as this had not happened before when the low fuel indicator came on.

I have a 2005 Toyota Prius, purchased new in oct 2004. I was driving on I-57 in illinois at 65 mph. Temperature outside was 91ã‚âºf. Low fuel warning signal began to flash. Since I planned to gas up about 25 miles away, I continued driving. Should have had approximately 2 gallons of fuel left. About 5 minutes later at 65 mph, the engine suddenly stopped running. The "red triangle of death" and the yellow "check engine" warning lights came on. Realized that the electric motor drive system was still working. Noticed that I was approximately 1. 5 miles from an exit. Slowed to about 45 mph and continued to drive using the Prius' batteries and electric motors. Pulled into a shell station and turned the car off. Began to refuel. After about 4 gallons, the pump clicked off. Tried again - it clicked off. Tried again and was able to refuel normally. In all, I added 9. 767 gallons. If the car has 11. 9 gallon tank, there should have been 2. 1 gallons left when the engine shut off. Upon restart, same engine warning lights were on, but within a few seconds they went off. Digital fuel gauge increased, one block at a time, until it indicated full. Car seemed to be operating normally. Resumed 65 mph. Car has continued to operate normally since. The shutting off of the engine was abrupt and would have been a safety problem had someone been following me too closely, or if I had needed full power to avoid traffic or an obstacle. Had read about this happening to other Prius owners and that some had reported not being able to restart the car. For that reason, I chose not to pull off on the shoulder and stop the car (for fear that I would not be able to restart it), and was fortunate to be able to drive with the electric motors to a nearby exit. Have not yet taken the car to the dealer to have the problem corrected. Have not had any parts replaced or software upgraded. Would appreciate any advice or service information you may know of.

(1) engine stalled when accelerating from stoplight. Weather was cool (low-50s) and rainy. Dashboard warning lights lit up ('red triangle of death', check engine, braking system) (2) driver pulled to side of road using electric power only (3) driver called husband, who advised wife to cycle the power off and on, possibly multiple times, until the engine restarted. Cycling power successfully restarted engine, but 'red triangle of death' and check engine warning lights remained lit. Car operated normally thereafter. Dealer applied TSB eg047-04 at no charge. Problem has not returned. Suspect this is another instance of 'prius stalling' problem. Given the number of incidents (1), the dealer response (satisfactory) and the recoverability from the problem (power cycle), I consider this a minor problem. Otherwise highly satisfied with car.

I had driven approximatley 20 miles to my hockey game and was driving at 40 mph. An ! and check engine light came on and the car was then reduced to only running off of battery. I was able to pull off the road without danger and shut down the car and checked the oil and gas to verify that wasn't the cause of the issue. After approximately 3 minutes I started the car and the ! and check engine light remained on, but the gas engine was functioning correctly. I drove the remaining 3 miles to my destination and called Toyota roadside assistance and arranged for a tow truck. After finishing up my hockey game ( 1 hour) I was able to start the car and there were not warning lights or issues. I canceled the tow truck and drove the car to the dealer. The next day the dealer updated the code in the car to us TSB eg047-04. I have been driving the car since they updated the code without issue.

Bought a 2005 Toyota Prius on 5/16/05. On the second day it lost power on the highway at 60+mph. Engine light and ! light on. Car ran well enough to take to dealer after re-starting a few times. Lights remained on until re-started at dealer. Car remains at dealer.

My 2004 Toyota Prius stalled while traveling about 40-45 mph with a full tank of gas on 5/14/05. The check engine light came on and it coasted to a stop. I turned off the power switch and restarted it and the engine came back on and ran fine except with the check engine light still on. The next day the check engine light was off and the engine ran fine. I took it in to the dealer's service center and they said they did something with the softwear and it should run fine now.

Without warning the check engine light keeps coming on. Consumer has taken car to dealer four times for the same problem. Dealer replaced different parts and the problem was there after three attempts to fix it. Consumer just got vehicle back for the fourth time. Manufacturer will be called today. Consumer was told they have never seen this problem in any other car.

2004 Prius, gas engine stalled while excellerating to merge onto freeway during rush hour, was forced to exit on electric engine in heavy traffic driving at 30mph. After exiting freeway and turning car off it would not restart. Vehicle finally restarted and I was able to drive with master check engine light on. Dealer said the car needed to have software reset, but never gave explaination of what caused original problem. I am guessing at the incident date it was month or so back.
