The local dealer and the manufacturer were contacted regarding the failure, but no assistance was provided. The failure mileage was 37,000.

Radio will constantly reset as well as the in-dash clock, and the tire pressure light will illuminate and flash. I found this appears to be a consistent issue with 2014, 2015, and 2016 Toyota Corolla's on youtube.

My vehicle was backed into while ì was inside of it in a parking lot. Due to my horn failing. , I was unable to alert the other driver to see me. The clock spring is what failed the first time at 95k they replaced it. I'm now at 147k and it failed again . Now I'm discovering that if it does not work, there's an electrical circuit failure and that the airbag will not deploy if I get in an accident. This is a serious safety issue and I feel Toyota should be responsible for it for the life of the vehicle . A horn should never go out. Especially if it not working will keep my air bag from functioning properly . 850 out of my pocket is way steep. The replacement part lasted half as long as the original part did when I bought the car that to me seems like a faulty part this should be obvious and they should just fix the problem cuz I might have to just consult an attorney should they choose not to. The attached photo shows what happens when you can't beep your horn at somebody who's about to back into your car !!! my car still has not turned on any kind of warning lamp for the airbag or any kind of malfunction light, no warnings on my radio. I have noticed that my lane departure warning seems to work intermittently along with the automatic high beams that like to flash my high beams in people's face for some unapparent reason which also seems like a safety issue. If I had to take my car to an inspection station it would not pass an inspection due to the horn not working ! you cannot take your child to the department of motor vehicles and let them take their drive test if your horn does not work ! which happened to be my case !! very disappointing to say the least especially when you've paid $30,000 for a car.

My 2021 Corolla showed an engine maintenance required message. This message pertains to replacing the engine coolant bypass valve - a common occurrence for the 2019-2023 Corolla/rav4 models. I have seen multiple instances online of complaints of this same issue around the 50k-60k mark of the vehicle. This should be a recall due to how common the problem is. I’m here to add on to that tally of complaints that have already been submitted.

After shortly pumping gas, I received a alert on my car that I needed to check my fuel cap, after checking fuel cap I proceeded to drive on the highway during this time a multitude of sensors started to go off on my car, and it started to drive weird there were light such as my interlock, being deactivated, parking, brake, deactivated, malfunction of vsc, collision deactivated. Then suddenly while driving at an accelerated speed, and trying to slow down, my engine turned itself off, and I was not able to re-crank my car. There is an active recall with Toyota for the fuel pump, which I was told by Toyota was the issue, but due to my VIN not being associated they would not repair as a recall.

The contact owns a 2022 Toyota Corolla. The contact stated that while the vehicle was stationary, the emergency button failed to respond. There were no warning lights illuminated.

The vehicle was not taken to be diagnosed. The vehicle was not repaired. The dealer was not made aware of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 58,000.

I just had to replace my transmission. 2 days later I have my check engine light, secondary collision, pre collision and parking brake malfunction lights came on. There is a osc recall that could cause these issues, but they’re saying stated my specific vehicle isn’t under a recall.

The contact’s mother owns a 2020 Toyota Corolla. The contact stated that while looking in the list of features on the infotainment center, the forward collision, brakes, accelerator, lane assist, on-board collision, and other safety features were flagged as malfunctioning. The contact stated that the list of malfunctioning systems seemed to have increased over time. The vehicle failed to turn off intermittently, causing the driver to make several attempts to turn off the vehicle. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 80,000.

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.

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.
