Electrical System Problems of Toyota Corolla - part 2

My 2021 Toyota Corolla's engine coolant bypass valve has shorted out once again. This is the second time this has happened in less than 40,000 miles. The vehicle has been inspected by two different dealers one two separate occurrences for the same issue, even after replacing the failed equipment.

While turning left out of a drive through my the steering locked up and shot to the left causing a run up on the curb. However after a second or two it cleared. Upon shutting the car off and restarting driving in a parking lot same problem occured steering wheel shot to left causing me to almost loose control then all electrical power was lost in the vehicle. The steering wheel fault came up on the dash and would not let me control the wheel.

While driving, my vehicle gas pedal becomes unusable, and two warning messages appear on the dash "charging system malfunction" & "low oil pressure" forcing me to pull over in traffic to restart vehicle. This has happened to me 9 times already in a span of 2 weeks. This same issue has happened to a few others and one stated "unfortunately the techs at the dealership couldn't figure out the issue as no errors were popping up when they hooked up the car to get a read out, so they called in a Toyota rep and even he couldn't figure it out. " and later stated, "I've heard from 5 other people who had the same thing happen with their Corollas; one lady was even driving on the freeway when it happened to her. I reported the issue to the NHTSA and can only hope that enough people did the same so that Toyota is forced to deal with the issue. " I am experiencing the same issues as this owner and this needs to be investigated!.

I am experiencing a recurring issue with the data communication module (dcm) in my 2020 Toyota Corolla. This component was previously subject to a recall, which I addressed at a dealership. However, the problem persists, and many other Toyota owners, including those with rav4 models, are reporting similar issues. Discussions on forums such as Toyota nation and Toyota owners club highlight these ongoing concerns. My vehicle is out of warranty, and replacing the dcm is estimated to cost over $800. I have confirmed that the issue lies with the dcm system, as removing the corresponding fuse eliminates the error message on the multimedia system. However, this circuit also powers the right speaker and microphone, making it impractical to simply disconnect the module. The local dealership has quoted $205 for diagnostics, despite my prior identification of the problem. Revisiting the original dealership where the recall work was performed is not feasible, as it is located across the country. Toyota has not offered a remedy, leaving me without an affordable or practical solution to address what appears to be a manufacturer fault. I am seeking assistance and accountability for this persistent and widespread issue. . Read more...

Car would not start/turn over - not battery related. Toyota determined the ecu went bad and stated the cause was improperly jumping the battery. The issue happened randomly one day (car was driving fine previous days).

To start, on [xxx], I was going through an intersection on a country road and my automatic emergency braking engaged for no reason. My car stopped despite no other vehicle or object being in my way or anywhere close to me. I found it really weird but did not think much about after the fact. I have also heard a rattling noise under my hood since [xxx] and have reported this to Toyota and tried to have it fixed multiple times (and showed them videos) but they were never able to duplicate the noise so it has not been remedied. On [xxx] I was traveling on a highway during rush hour and the traffic in front of me came to a sudden stop. I braked as hard as I could; my automatic emergency braking did not engage and I rear ended the car in front of me (minimal damage to that car). We both immediately pulled partway onto the narrow left berm (we had both been in the left lane to get onto another highway). My car then turned off by itself and gave me an engine warning (I believe low engine oil- I had just had it serviced 3 days prior). The other car owner and I exchanged information quickly and decided to drive away because we were blocking rush hour traffic and it was dangerous. However, my car would not start back up. I called 911 and they came to use their vehicle to push me to the right side of the highway onto an exit where I was no longer blocking traffic. During the wait, I felt like I was going to die with traffic honking and swerving to avoid me. When the police officer was moving my car, the parking brake engaged when I put the car in neutral and would not turn off, so the smell of burning rubber was strong since the tires would not roll. Once the tow truck driver arrived he was able to use jumper cables to disengage the parking brake but the car still would not start. There were no prior warning lights. The car not starting was confirmed by the dealer- they are holding off doing maintenance to have an engineer check out the car and figure out what happened.

The vehicle flashes ‘connected device is not compatible’ with the ‘sos button flashing continuously red then green. ’ this message causes the microphone to remove 1 to 3 seconds of sound every 5 to 15 seconds making a clicking noise when speaking on vehicles bluetooth. This is typically corrected by a dcm reset and firmware update. Not only is this incredibly inconvenient during normal conversation but having to repeat random portions of the conversation is irritating at best. Recently I had to make a 911 call and had to repeat myself several times to request emergency services. This glitch caused the emergency 30 second call to be extended roughly 1 1/2 to 3 minutes delaying response time. If the clicking occurs while the other person is speaking this is not noticeable. This is an identified issue only covered under basic warranty with specific TSB correction. This defect causes portions of vehicle occupants conversation to be removed and replaced with a clicking noise.

When using built in carplay navigation the gps will start drifting 10-20 feet from the highway into field or other highways causing it to reroute constantly. When phone is disconnected from carplay during the gps drifting current location will go back to right location on the phone. We tried connecting different phone to Corolla all had the same issues. My other two cars don’t have this issue using the phones. Dealers won’t address the issue.

Engine coolant bypass valve malfunctioned at 34xxx miles, causing “engine maintenance required” this could cause the engine to get too hot or not hot enough and affect the internal components of the engine. After speaking to others with the same model and even other models, it seems to be a ongoing issue for many people.

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 contact owns a 2020 Toyota Corolla. The contact stated while parked, they shifted the gear to drive and then reverse, but the vehicle would not move. No warning lights illuminated. The vehicle was towed to the dealer and a diagnostic was performed. The vehicle was diagnosed with a locked cylinder. 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. The manufacturer was not made aware of the failure. The approximate failure mileage was 90,249.

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.

Brake booster failure and lost power due to malfunctioned battery . Car could not start and had to be transported by road assistance to dealer for repair. Dealer had to replace brake booster as well as replace battery with a new one. Car was purchased brand new in March 2023. Only 10700 miles on it.

My airbag light stays on and I heard if the air bag gis off it could have metal in it. . That don't sound like something I want to happen. . . Also this cars power go's out and back on its scary when your driving down the road. It only has 141k miles something is wrong. . .

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.
