Vehicle would not start. After the vehicle's battery was jumped, the vehicle would start, but upon moving the vehicle, the dashboard message read, "engine stopped - steering power low. " there are numerous entries in online forums of others looking for solution for the same issue. Sometimes others have said that this occurred while in stop-and-go traffic on the highway or idling at a red light. Clearly, if a vehicle becomes disabled on a roadway with no prior warning of a failing battery, that is a safety issue. There was no warning of a failing battery. Battery was replaced, which was a surprise for a 2020 vehicle. However, this issue has occurred in newer vehicles as well if you review the comments in the online forums. Failed battery was tested and measured 67cca/295cca @11. 44v. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My vehicle stalled when pulling out into traffic. I lost power steering and electrical and the engine died. The vehicle had to be restarted to continue driving. I was going about 1 to 2 mph when the issue happened. The vehicle was in motion and stalled while other vehicles were in motion putting my safety at risk, had I been going any faster or if there was an increased amount of traffic. I reported the problem to the dealer service center, but they were unable to reproduce it. The vehicle was inspected by Toyota only, no police or insurance. When the issue happened, a warning light appeared on the dash similar to a circle with an exclamation mark inside. There were no messages and no other symptoms prior to the failure.

A Toyota owner is frustrated with a faulty navigation system that repeatedly crashes and refuses to update. Despite multiple dealership visits and a customer service call, the issue remains unresolved. The owner argues that the malfunctioning system poses a safety hazard, as it could potentially direct drivers to dangerous roads.

An engine maintenance required popped up in the vehicle and was unable to be removed took the vehicle to get checked at a Toyota dealership and they advised it was the coolant valve bypass was faulty.

Dashboard stated engine maintenance required- visit your dealer and it turned out to be a bypass coolant valve malfunction per Toyota mechanic specialists.

I was driving down the highway and I heard a tapping noise thought it might have been a piece of trim loose on the car so I pulled over and stopped. Immediately the engine died would not restart. I looked under the hood and the radiator cap had blown off and all of the coolant was gone the engine had overheated when I put compression test was done there was water shooting out of the valve cover. It was diagnosed as a blown head gasket the car never gave any warning lights or the thermostat never showed any temperature problem at all. I was sitting on the side of the highway for 12 hours trying to figure out what to do with the car because I didn't have money for a tow truck. Fortunately nothing terribly bad happened as a result however had I not heard the trim loose and pulled over and the car had died in the highway it could have been way worse.

I have been driving my car since 2016, however since Nov 24, 2023. Incidents that alarm me have happen. I have filed a police report but don't have the funds to get vehicle swept. All of these events occur while I am driving. Passenger windows goes up in and down a lot. Static in my speakers. Steering wheels lock. Somethings draining my battery. Though I have ensured nothings on or there isn't any short fuses. Doors unlock. Door beeps though someone has had access. Trunk pops open. I am reaching out to NHTSA because my safety is at risk. Is any other Corolla owners reporting this. Please assist me.

Electrical issue on vehicle says that vehicles safety features are unavailable and all the light indications on the dash are lit up. It was taken to the dealership several times but the issue still hasn’t been resolved.

I purchased my car in March 2023. From the first week, it wouldn't start sometimes. Id wait 5 minutes, then it would start fine. I thought it was when it got wet, at first. I also had a certain part replaced air flow compressor, possibly was called?, thinking this would fix it. It did not. In fact, the problem seemed to be happening more and more but, always, if I waited 5 to 10 minutes, sometimes messed around under the hood, it would start. This was not very comforting however, when it would stall at a light and not start right back up. I took it to autozone and was run on the diagnostics machine. Was told it needed new spark plugs and ignition coil packs. Which I got and replaced. Still happening. I took back to autozone, had it run again on diagnostic. This time it said battery. So I had a new battery put in. Still happening. All along, might I add, my fuses will blow randomly, my headlights and taillights will blow for no reason. One taillightooks like it melted through the plastic before it decided to blow. I e replaced some fuses, only to have blown again. I also have replaced the light bulb in taillight, only to have blown twice more. This is very dangerous, especially at a traffic light or, late at night if I need to go somewhere or leave somewhere and it won't start. I've been stuck in the middle of the road, on the wring sidevif the riad, in the midfle if a snowstorm, with it not starting for me. Also, it was gett5really cold without heat and, I was nearly hit several times as I was also at the bottom of a steep hill when my car decided to stop sliding backwards and stall on me and would not restart. That was the most fearful I have been with this issue and with good reason! I now see several others having similar issues with their same exact car. Why isn't Toyota addressing this?.

Experiencing a high-pitched whining/ringing sound from the air conditioning system. It is highly distracting and irritating, and basically prevents the use of some fan speed settings for extended durations due to the pain it causes. Many other Corolla owners are experiencing the same issue and Toyota refuses to take action in every case, saying the problem is "characteristic of the vehicle" or something to that effect. Issue is well-documented in this forum thread among other places. . Read more...

Vehicle has numerous electrical/mechanical issues that seem to stem from an autonomous learning remote sensor. The problems include, but are not limited to 1. Seatbelt sticking on driver’s side, problem resolves itself, possibly after someone has had a good chuckle on satellite watching the driver struggle to disengage the safely belt, 2. Trunk remotely popped at speeds ranging from 0 (park) to 70mph on highway, 3. Ignition light on and off, usually correctible by disengaging and reengaging battery lead, 4. Car shutoff and burglar alarm engaged while in park, again , correctible by disengaging and engaging battery lead, 5. Car gas gauge reading false on the light side ( less than e), then after disengaging and engaging battery lead, reverts back to 1/4 tank, 6. Clock time changed, presumably after vehicle shutoff and restarted in the middle of the night. Clock reset via auto computer, etc. All incidents are usually corrected by disengaging and engaging the battery lead, after a brief pause to reset the vehicle’s ecu.

The dealer stated it was part of a previous recall but they could not repair it under the recall due to mileage. The vehicle was repaired. The contact referenced NHTSA campaign number: 19v544000 (electronic stability control, service brakes) as a possible solution however, the VIN was not included in the recall.

Air bags did not go off during the crash and the seats belt tensioner didn't lock up the seat belt resulting in injury to my self. Radio keeps rebooting.

Radio is not working and the light stays on the radio making it hard to drive cause it is so bright which is dangerous.

There's an electrical problem going on with all Toyota vehicles coming out with the new navigation system where goes out and keeps rebooting. Multiple times on cars a year have reported this issue. Causes a distraction as screen goes on and off randomly as you drive and backing up. Also without it you can't see your gps and find routes. Just simple search and there's many complaints about this issue from consumers being affected as fast as 10 miles into owning car to month or six. Not worth repairing as goes out every other month and don't even last a year before goes out.

Around 40k miles I received an engine maintenance required warning. After some research engine maintenance and engine service required are two very different indicators. I received and p2681 code meaning the electrical coolant bypass valve had failed unfortunately one can’t tell if it’s stuck shut or open this could lead to one’s care over heating and or damaging one’s engine. After some research I’ve come to find out most 2020-2024 Corollas have been having this issue tends to happen about 30-50k miles.

Phone charging cord is prone to getting pulled into the steering column and extremely difficult to remove. When I was able to remove the cord, I discovered a wire or spring the steering wheel assembly must have come undone, because the airbag light is on, and my cruise control no longer works, and neither do the steering wheel controls for the radio.

On the morning of July 21st the vehicle was parked in the garage the night before when all of the sudden our neighbors were yelling at my wife and I to exit the house because they saw fire flames and black smoke coming out of the garage. Everything in that garage and part of the house was destroyed. After it was safe to enter the house we noticed the damage was concentrated where the Toyota was parked, the explosion from the engine caused the hood to almost touch the windshield. Half the engine was gone.

I was at a red light. When the light turned green and I pressed the accelerator the car wouldn’t move. The check engine, charging system malfunction and electronic power steering system warning light appeared on dash. Car locked up. I moved car into neutral and then drive and car was able to move. Took it to dealer next day. Cars almost ran into the back of me! I had just turned on the street from I-85! so far it hasn’t been reproduced at dealer.

We discovered that there was an explosion of some sort inside the car on the passenger side, which seems to have potentially involve the air bag system and/or electrical around the system, but this is not entirely known. The car was parked at the time and had not been driven for approximately 65 hours. It appears there was a fire but we did not witness. The dash is melted leaving a gaping hole, what appears to be portions of the air bag are partially disintegrated and stuck to the ceiling, the ceiling is charred, the sun visor is melted and distorted, and hanging down, underneath the dash is also melted, and the smell in the car is absolutely stifling. The windshield is shattered in one spot, with additional cracks stemming from that point of contact. The windshield is damaged from the impact from inside the car and is pushing out. The car was locked, there is no evidence of forced entry or attempted forced entry. It has never been in a collision. The car was parked three feet away from our motorhome in the confines of our RV spot at an asphalt campground. The safety of all in the area was at risk, and furthermore, since this explosion was unprovoked, if we had been in the car at the time, it's unimaginable as to what sort of bodily damage the passengers, especially the passenger seat occupant, would have incurred. I do not believe the problem can be reproduced, but the car has yet to be inspected. I am currently awaiting insurance to take the car via tow truck to inspect it. There were no warnings, messages, or other symptoms.

I was driving on the road and I heard something like an explosion, I turned the emergency lights on and stopped to find out what had happened. I saw the sunroof completely broken, fortunately I didn’t get hurt but I got so scared and I don’t know if I will feel comfortable driving my car again.

My car had issues completely shutting down on me while I was driving which was very dangerous my abs light and steering light would come on each time it shuts down and I wasn’t able to use my power locks lights I couldn’t move it out of park or nothing those were the only two lights the was still able to start up just couldn’t move or use any buttons my keypad wasn’t working so that indicated that it was an electrical issue so I thought it was my battery even though the light wasn’t on for the battery I had my battery tested and the code came back and said I needed an alternator so I had my alternator tested and it works perfectly fine so then I checked the fuse box and it was burned up so that was my whole issue.

Check engine light on. Cruise control stopped working. Fuel cap tightened.

My car shows that the vehicle needed to be serviced, in checking the Toyota app I saw there was a warning for the adaptive lighting system/electrical concern. The warning light had been on for some time, thinking I was due for regular maintenance like an oil change I had ignored it for a bit. Everytime I would start the car this warning would appear. I too the car in for service, they also did a 20k maintenance service and kept the car overnight overnight as they were unable to locate the issue same day. The following day I was advised they couldn't determine the issue and they cleared the code.

One day car does'nt crank. Instrumental panel was dark. ' opened hood checked and closed hood and car started. After 3 weeks later while driving interstate this happened again twice within 2 miles apart when I was returning home. It happened again at 65 miles per hour on the highway. Cruise control lost, lane assist failed instrumental panel getting dark and a message was reading " check the electrical system". At the dealership parked at the service desk, they asked whether I took a video or pic of the incident. When they tried to start the car to move to the shop car didn't start and same incident happened. Tech found positive terminal cable loose. He retorque cable and after that we do not have that issue. Its a new car and battery terminal loose? another electrical issue with the car was unable to open and close front passenger windows from the drivers side switch. Tech found right side windows was not calibrated.

Volume of media from certain apps can't be adjusted. The vehicle says that if media is not playing, the volume can't be adjusted. This can cause distraction while driving and increase risk of a crash. Specific application where this is the case: youtube audio through an android auto connection. Yes it is available for inspection. My safety and the safety of others is at risk, because all Toyota models with this infotainment system function the same way. Drivers may choose to become distracted by their mobile device while trying to adjust the media volume, risking a crash. The problem has not been reproduced or confirmed by dealer, however it would be very easy for me to do so. The vehicle has not been inspected by any party outside of the Toyota dealership. When attempting to adjust the volume, the volume level will appear as a numerical value in the infotainment screen only if there is currently "audio" playing. If there is no "audio" playing, an error message will appear telling the occupant to begin playing audio to adjust the volume. This becomes an issue when using an app like youtube to play audio. With youtube premium, you can set a playlist of music, videos, or podcasts to listen to with the screen of your mobile device off. However, the infotainment system will not detect the audio the speakers is playing as audio, and will not adjust the volume. This leaves the driver with no choice but to pay for a spotify, sirius xm or youtube music subscription in order to listen to music or media and adjust the volume safely. Reproduction: start vehicle. Start android auto. Start playing media through youtube. Attempt to adjust media volume using the dial or buttons in the vehicle. Error message should appear. Only way to adjust volume is to switch to fm/am radio, play spotify or other app to adjust volume and then resume youtube media (requires touching phone), or don't use android auto and pay for Toyota gps. How to fix: allow volume adjustment at all times.

Car stalled at stoplight. Loud tone sound with ‘power steering low’ indicator with check engine light on. Wheel locked. Needed to put in park and restart car. Very scary and unsafe! multiple people on reddit and youtube have reported this!.

I bought my car Toyota Corolla coss has three months with 3,700 miles on it. And has had two times problems. The first time, on February 28 2023 at 8 a. M. , I was at a traffic light stop my car about 15 seconds later when I heard a warning beep. The message read "low steering power," low battery, and then steering lock. I tried to turn off the engine button, but there was no response. I pressed it three times, put the handle stop on the park, and then started it again. My car was parked in the middle of the road, causing a traffic jam behind me, and I couldn't get out because it was dangerous. The second time in March 10. 2023 3pm. After the stop at the light and anything like first time. . . It was rainy both times. I'm worried it's dangerous on the highway. It was raining and I had my wipers on and my stop and start system on. I haven't reported it to Toyota dealership. Both of them are in the middle of the road. I'm not sure if there are any defects in this car. Thank you!.
