2014 Toyota Prius: headlights failing or too dim

Filed Oct 11, 2024 · Brakes · FL

The braking system is failing with the following codes I tested with the BlueDriver scanner. Code TypeCodeDescription ABS CodesC1241Low or high power supply coltage ABS CodesC1391Abnormal leak in accumulator Main BodyB1206P/W Master SW ECU Communication Stop Main BodyB2321D-Door Motor ECU Communication Stop Main BodyB2430LED Headlight LH Entry and StartU0142Mainbody Ecu Communication Circuit Entry and StartU0155Lost Communication with Instrument Panel Cluster Control Module The car is available for inspection. This puts the drivers, myself and fiance, at risk of catastrophic collision in the event that the brakes fail while driving. I will call Toyota to obtain a replacement of the system that has occurred with many other drivers. The vehicle has not been inspected by manufacturer yet but it is important to know that this is a serious problem that could kill people. The problem was identified when warning lights came up on the dashboard but there is also a sound coming from the brake actuator that shows a problem. The problem is due to manufacturer error, I have driven the vehicle normally.

The driver side headlight, running high beams and low beams, have stopped working despite changing the bulbs. It seems to be an issue with the ballast going out and/or just not working anymore. This seems like a major safety issue.

- my name is [xxx]; I reside in ca. 1. I have a 2000 toyota camry & a 2014 toyota prius. 2. The 2000 toyota camry has the day time running lights as a standard feature. 3. The 2014 toyota prius does not have the day time running lights as a standard feature. 4. In states like ca & I bet in other states - day time running lights & head lights getting turned on with limited sun light should be made mandatory. 5. This is more of a safety feature than an option. 6. It will help prevent accidents, it will help compliance with the law where applicable when it is raining & head lights are mandatory 7. It will also save anyone from getting traffic violation tickets 8. Can you all pls look into this & help review to make this as a mandatory feature? Thanks in advance [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *cw

The headlights on prius are not bright enough to see the road ahead of the car. The are on but somewhat dim. Other drivers can see the lights, but the lights are not bright enough to illuminate the road in front of the car. This occurred after I took the car in to the dealer to complain about a series of electrical related problems that all started happening at the same time. The dealer replaced the headlights after they determined the headlights had burned out. Immediately, I noticed that during times when I was driving at night, the night visibility was not what it had been prior to problem first occurring. I have taken the car back to the dealer bu they say there is nothing wrong with the headlights.

Headlights and cabin lights failed to turn off when remote lock was activated. Lights were then turned off manually. Five hours later, in the parking lot, the car was nearly completely dead. Last time it happened, we left it and it recharged itself. This time, it did not recharge itself; it was completely dead the next day. We had to have it towed to the dealership, who "jumped" it and let it sit overnight. They say it now has no problem.

When the headlights - not drl - are on and the dash lights are on low the instrument panel lights go dark while crossing under shadows (bridges, trees, etc.) in daylight and at night when going from bright lights on highway exchanges back to dark. Toyota dealership was able to reproduce the day-to-shadow problem in the shop (shop manager) the service manager was able to reproduce the day-to-shadow problem on a 2065 prius v. I was told that this must normal for newer priuses as no one else has complained about it. It can also appear to happen during daylight hours when wearing polarized sunglasses. The dash lights are on high, the headlights are on: driving under the underpass the panel light lowers so much they appear to go out. The car is a new-used car. The problem did not appear during test-drives, all taken in bright texas sun. The first time this occurred was on a sunny morning while driving through a park. As I went from bright light to shade the dash lights would go dark. It frightened me, but I forgot about it, until I was driving on I-35 in rush hour traffic at 4pm on a sunny day: the interstate in downtown has upper and lower levels; while on the lower-level the instrument panel would go dark, then light as the shadows were exacerbated by those cast by tall buildings near the interstate. It occurred most recently after leaving the dealer yesterday. Driving on I-410 in san antonio on an overcast day, everytime I drove under an overpass, the dash, radio, climate lights all went out. At night, it occurred when traveling on us-281 near lockhart, tx: once I was under full-light, the dash lights, etc. Went out until I had been driving in the dark for about 10-20 seconds.

Point sources of light (I.e. Brake lights, headlights, traffic lights, etc.) at night time and to a less visible extent in the day time are duplicated or triplicated at distances through the front windshield. As the light source is closer to the car, the ghosting effect diminishes. This problem does not occur when looking out the side windows or rear windshield, but only occurs through the front windshield. This prism effect induces nausea and is incredibly distracting while driving.
