2021 Toyota Corolla ELECTRICAL SYSTEM,UNKNOWN OR OTHER

Today I noticed that both of my door front locks passenger and driver side do not even actuate to have the door locked and unlocked by key of by the alarm. They completely stopped working. Even I contacted Toyota Corporate several times about this issue (800) 331-4331 and got ignored. This is a safety issue that needs to be addressed immediately. This is a safety concern for me and family.

When I was driving on the freeway on January 21, 2022, I had my iPhone X plugged into the car's infotainment system via USB to enable Apple CarPlay and navigate using Google Maps. In the middle of driving, the navigation system lost accuracy of my precise location. It continuously kept rerouting, as it believed that I had exited the freeway and was now on the side street. GPS precision is unreliable when the connected phone is not unlocked and on the Google Maps app (sometimes it works, sometimes it doesn't). This is obviously a safety hazard, since I have to exit the Google Maps app on my phone, reopen it, and reroute to the location so the software accurately picks up my location (luckily, the car has lane-trace assist). Another issue is when using Google Maps (an issue with all navigation app, really; here I use Google Maps as an example, but I've had an issue with all maps apps I use, including Apple Maps) navigation with Apple CarPlay and the iPhone locks itself or the driver exits the Google Maps app on the phone. Sometimes, when the phone locks itself from idle usage (as it should, since the driver is focusing on the road) or when the Google Maps app is exited (but not closed), the navigation interface on the car's infotainment system freezes. It shows the current location of the vehicle as stationary when it really should be moving. The intended functionality is the navigation software should continue running and updating as the car moves, regardless of whether the phone is locked or if the Google Maps app is only running in the background. This issue happens sporadically, but poses a significant risk of a collision, as it forces the driver to use their phone and reroute their navigation instead of paying attention to the road. Toyota needs to coordinate with Apple to address this issue on Apple CarPlay and subsequently release a software update to drivers.

While driving the vehicle the brake hold system was activated at a red light. While proceeding through the light within (about) 5 minutes the vehicle indicated a brake hold malfunction. An odor of smoke was also present, at that point I turned off the vehicle and inspected the origin; the trunk. Upon opening the trunk the right side had a sizeable fire growing towards my assets. Police did arrive on scene, an adjuster has examined the damages, however this has not seemed to be replicated. I believe the risks associated with this incident are quite evident. There was no collision.

After bringing my 2021 Corolla into a certified mechanic that I personally trust is the most skilled and talented for Toyota brand, as a specialist for asian make vehicles. I was told that my unit was given a old battery despite the year of my vehicle. The safety of starting the engine was discovered 3 days ago. When I couldn't start the Car. I brought it to mountain view auto mechanics, in mountain view, CA. The mechanic I spoke with visually scans the engine and said that everything was not tampered with, but requires a replacement battery, by the Toyota dealership; any of the locations. Because the car is a 2021 it falls in the category of standard brand new warranty. A diagnostic fee has been said by Toyota of Stevens creek of the amounts of 230.00$ to find the issue. Even though I in with in warranty. I work at Quiktrak inc. as Field Inspector/authorized inspector my id# is CNP995 I perform inspection audits for vehicles and vessels all in the northern areas of California. I am complaining about my vehicle being un-safe for long term use, because of contraindications of how my car is. For the record. I have not modified any thing that would void my vehicles basic warrenty. Nor the CA emissions warenty
