Prius LX 4 cyl

  • CVT transmission
  • 93,000 miles

For the last 2 years, every couple months, I have to replace one lamp and within a month I will have to replace the other, then in another couple months start all over again. The last time this happened the right one burned some plastic on the back side of the light housing and upon trouble shooting the smell and reinstalling the lamp, the lamp blew up in my hand. So now I have the right lamp shining off in the ditch and the other one burned out again. This makes for a real dangerous early morning commute to work. I have two Toyota vehicles and have not had much trouble with either one until now but I'm about ready to get rid of the Prius. I have read complaints about people having the same problems but having a mechanic shop install the lamps for them ($450-1800) there is no way, I would pay somebody to install these lamps for that kind of money. oh, by the way, installing these POS lamps is another big pain in the butt!! TOYOTA!!! fix this crap!!! can't believe that with the awesome rep. that Toyota has, that they would even allow this kind of workmanship to exist.

Prius III

  • Automatic transmission
  • 40,234 miles

Four days ago, I got into my car (at dusk) to discover that BOTH my low beams were not working. I had to drive home in the dark (and on a somewhat windy canyon road) alternating between no lights and highbeams. The following morning I took to Toyota of N. Hollywood. My Service Mgr. said that both lights were burned out and needed to be replaced. It sounded odd to me that BOTH lights went out at the same time, but sure.. OK.. The replacement cost for part and labor was $110 per bulb. (later discovered online that the actual bulb is appx. $33). They estimated 3 hours for the repair.

About an hour after I'd left my car with Toyota, I received a call that the left-hand housing unit had melted and that too would need to be replaced... HUH?!?!? I asked if that was covered under warranty, and was told no. I made the point that I couldn't understand why a housing unit would melt, as the bulbs were factory issue and it makes no sense that in the design and creation, the housing unit wouldn't withstand whatever the standard heat output would be. My service Tech replied that it was not uncommon, and in fact it happens often with Tacoma model vehicles. I would have to pay for the repair. I told him to go ahead and make the repair, but that I wanted all the replaced parts when I picked up the car. I then went online and discovered two things; 1) there was a recall for Tacoma's for this very problem, and 2) the recall for Prius' light issues covered 2004-2009 year model.

From looking and researching online, CLEARLY this is still an issue. On the safercar.gov website there was a reporting of this EXACT situation to same exact year, occured four days prior to my incident. I will be reporting this on every and any website I can find, as well as writing to Toyota of America directly.

All the car front lights except the high beams stopped working. I just replaced all those bulb recently, two months ago. The high beams were changed last year but those are still working. In fact, I have already changed one small front light and headlight since changing it the first time.

This time all the lights went out together. I think it happened when the check oil sign went on. I'm not positive. I just know these lights are very expensive. Appears that Toyota has problem before. They obviously haven't fixed it. There is no reason for almost new bulbs to stop working.

Prius L4 1.8L

Now the light on the passenger side works periodically. When first took it to get fixed, the light was working. Several days later it was not. Toyota dealership reported that Toyota now has an adapter that would resolve the issue caused by the original wiring system, which turned out to be faulty. Their cost for the fix was $595 while our independent service shop quotes $438. A rather high price to keep headlights working which resulted from a poor wiring design.

I have had to replace my low beam headlights almost every couple of months for the last 6 months.

Highbeams work fine. I have had the car since it was brand new. I have never had any previous issues.

But now I am constantly changing the bulbs

Prius 4 cyl

  • Automatic transmission
  • 92,229 miles

I bought a used black 2010 Toyota Prius a little over two years ago. At the beginning of this year (2015), the headlights (low beam lights) started giving me problems. They got really dim at first, then one went out, then the other. I replaced them (being careful not to touch the bulbs with my fingers and wearing rubber gloves). Within three months, they both went out again at the same time. I had to drive about 10 miles to the nearest auto care center to buy and install new lights. Now, only about five weeks later, I was driving home from work in the dark (a 60 mile one-way trip on a VERY busy freeway) and both lights went out again! This is serious as I drive a BLACK Prius. I drive to work when it's dark and drive home when it's dark. Now, I have to take time off work to either go buy more bulbs and replace them or make an appointment to get into a dealer and pay mega dollars to have it looked at and fixed. As a single woman with only one vehicle, this is extremely annoying, not to mention the fact that it was terribly unsafe for me and all the other drivers on the road. I've heard the cost to fix is also around $1,000, which I don't have since I'm also paying off student loans and specifically bought the Prius to save me money on gas. The problem is ridiculous, and Toyota needs to repair all headlights on any Prius that have problems since the 2204-2009 problem is obviously still an issue!!!

Both my front headlights went out at the same time about two months ago. I had to drive 10 miles with my brights on and other cars beeping at me. It was crazy. I drove home during the day the following day and my son said they went on when he went to check them. They stayed on until yesterday. Now they are both out again. This time they are not coming back on. The fuses are good and bulbs too. Checking for a short? So many complaints about the 2010 Prius headlights that we need a new class-action lawsuit. They settled for the same issue up to the 2009 Prius. The problem still exists in the 2010. Any advice?

Having to change your headlight bulbs 3 times a year (at the least) is dangerous as one has to drive often with dimming lights. Also the plastic cover over the bulbs is fuzzy due to _? Overall lighting is bad at night and once both lights went out at the same time causing me to drive with "bright" on. A blight on a car that is overall great.

  • Automatic transmission

That was the First time my headlights went out. I bought it brand new off the lot just 5 months prior. Since that time my lights (low beams only) have been replaced at least a dozen times. They get really REALLY dim at times as well. Last winter (in Maine) I was driving and both lights stopped working and I was forced to drive home with my high beams on. Folks in the oncoming lane were none too pleased. My car is currently one eyed again...scheduled for diagnostics at the dealership to run diagnostics to find out if it is just a corroded "pig tail" receiver or if it is the entire electric harness. This car has been amazing and reliable except for the troubled headlights. I hope there is a recall because I hear that it is $400 or more fix.

  • Automatic transmission

I was driving one night and I went to turn on the headlights and nothing happened. I was driving blind. I went to the high beams and they worked. I have tried to fix this but I have not been able to diagnose the problem. I would like to know if there is a recall on the 2010 Prius for this problem. Or if anyone knows what the problem is please tell me. It doesn't appear to be the fuses.

The bulbs keep going out every 24,000 to 34,000 miles! The idiot auto engineers at Toyota designed a car that requires the entire front end to be REMOVED to replace a bulb!!! The consumer has to shell out on average $400 for parts and labor!!! THIS IS A JOKE!

You think you are saving on gas, but every 30,000 miles you are shelling out another $400 for a stupid bulb. Toyota should either warranty the BULBS for a respectable period or at the very least disclose this as a regular maintenance cost. I have now replaced the bulbs 4 times!

This is the THIRD time I have shelled out $400 to replace a light bulb at Toyota! Unbelievable! The idiot auto engineers at Toyota designed a car that requires the entire front end be REMOVED to replace the headlamp!! I only just replaced the bulbs 30,000 miles ago!! Toyota is extorting consumers to pay for their stupid engineering!!!!!!!!
