Selected complaints filed with NHTSA by 2008 Toyota Prius owners, lightly cleaned up (personal details are redacted by NHTSA).
This model car is equipped with HID headlights. The car has had numerous problems with the bulb not lighting on one side. The light could be cycled off/on and this would allow the lamp to stay lit for an unpredictable amount of time. Sometimes this cycling would allow the lamp to stay on for an entire trip and sometimes the headlights would have to be cycled off/on again. Replaced the lamps today with brand new bulbs. Both lit during the initial testing. Later in the day the left lamp does not light even when cycled off then on. The headlights on this car are unreliable. The trouble in changing the lights would have been fixed with traditional halogen lights but now further troubleshooting is required or replacement of the igniter or bulbs. Headlights on cars in the 21st century should be completely reliable especially after replacing both lamps with brand new bulbs. …
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. [redacted] .
I had purchased this 2008 Prius touring model used on 4/8/22. The first time I drove it at night I was on the freeway traveling at 55 mph and suddenly had almost no visibility due to loss of headlights. It was terrifying and pure luck that I made it off and home. The headlights turn off one at a time. I took the car to Atomic Auto in Portland, Oregon and they said the type of bulbs in the car often do this when they are failing and need to be replaced. This shop put new bulbs in yesterday, May 12th. It was raining heavily when I left the shop and I turned the headlights on. They failed again in the same way. I had no idea there was a problem like this with any car. I have searched online and now know that this has been a problem with Toyota Prius.
On June 1st yesterday this issue happened again but it was the taillights. The uploaded document is from the most recent repair shop bill for the front headlight (under warranty since it stopped working so close to the previous repair) Intermittently without cause the front right head light goes out (seems like every 3-6 months). And every 12-18 months the tail lights go out (the brake lights still work). The mechanics can't tel if it's a circuit board issue (possible lack of cooling/fan), loos connections and or just poor design. No matter what it is dangerous as I I unexpectedly had to drive on hwys in the dark not knowing my lights all of a sudden aren't working. Thank you very much.
I am currently having this issue with Combination Meter, which means the Prius dash board will not show any speed, fuel, P, R, D label and many more important information is not shown on display. I had complained to Toyota, CASE[redacted] on 19Dec2022, I have spoken to Danial N and manager Alex S from Toyota. They both have denied solving this issue from Toyota as the Warranty Extension ZTV has expired. Even I had provided them proof that Toyota knew about this problem, please see [redacted] from Toyota regarding this. My Prius has 258000 miles, and it is 2008, It is high mileage as per their documents this will accrue in high mileage Prius with cold weather. I live in NJ, and it is getting cold and my car as high miles. Toyota refuse to take care of the problem and I as a consumer will have to pay over $1200 to get it fix as this is only done at Toyota dealership. …
My passenger side headlight blinks off while driving (in motion). Turning the lights off then on again corrects the problem for a short time, but then it goes off again. Replacing the bulb did not correct the problem.
My lights have been going off intermittently for a few months now. I went to the dealership for a 12 v battery issue and a couple of recall items, including the hybrid cooling recall issue and the dealer thought this might fix the issue but it has not. What happens is that at any given moment, each and every day/night, when I am driving one or the other headlight will go out. Occasionally both will go out. The only way this is remedied is when I toggle the light switch off and on. Sometimes it takes 2-3 toggles to get the problem to resolve, the suddenly and again, and again the one or the other lights go out. Apparently this is an issue with Toyota Prius's of my year. This happens every time I drive and there is no rhyme or reason. I happens when I am driving. …
This is the intermittent headlight issue for 2008 Toyota Prius' a front headlight will go out, and if you turn off an on the lights, they both come back on. This first happened to me a few months back. The only suggestion to fix this is from Toyota which is to take the car to a dealer and for $550 they take off the bumper (do some trick), and put in new bulbs. Instead, I spent $180 for 2 new bulbs, and replaced them myself (without taking off the bumper and doing the trick), and it worked for 2 weeks before 1 or the other bulb intermittently goes off. At least they are brighter now, though this is 1) a safety issue as the lights act unpredictably, and 2) replacing headlights is on the order of changing a tire or windshield wipers. It's like changing a light bulb, no?! The real issue is the ballasts which as I understand it regulate the lights. These are not easy (for me) to fix. …
While driving down a two lane highway at 55mph in a very remote and dark location, both headlights failed. I was able to avoid what would likely have been a fatal collision only because I was on a straight portion of the road at the time - had this happened a few seconds earlier, I'd have been taking a very sharp curve at speed and would likely have driven off the road before I could react. I was able to pull over and toggle the switch to reactivate the lights, but I was in an area so remote that calling for a road service was not possible, so I had to drive the vehicle another 35 miles to reach my home. I was told by the dealer that it was likely a "fluke" - but... Both headlights failed, simultaneously, a second time, a few weeks later. Toyota wants to replace the bulbs but will not guarantee that they will not fail, simultaneously, again. …
My wife and I own 2 Prius 2nd generation models since 2014. The issue is with the instrument cluster randomly malfunctioning and not displaying when the vehicle is on and sometimes not being able to turn the vehicle off. It happens while driving, stationary, raining, just randomly. This has happened more than 10 times on my car alone, and my wife can contests to hers as well. What we both are experiencing is one of many situations. While driving the dash lights and interior lights will just not work: I'm unable to see driving speed, if my headlights are on. Even while stationary we experience the same thing. The main reasons for reporting this is because coincidentally it happens to both of us at random times in 2 different vehicles same model and year. From my own research this has been going on for a while with other owners with the same models. …
