Electrical System problem #1

Car was vandalized on 12/7/21 and alarms did not go off. Car alarm doesn’t work, hasn’t worked.

Electrical System problem #2

Both front door lock actuators not working properly. The car only has 40225 miles and is garage kept. What the possibility of both going bad and is this a manufacturing defect and should be a warranted part?.

Electrical System problem #4

The power door lock on the driver's side stopped working with the key fob. Can only lock and unlock by use of actual key or by manually pushing door lock. The passenger's side door lock is starting to show the same signs as the driver's side did before it stopped working completely. Sometimes will work properly and sometimes it won't.

Electrical System problem #5

My 2014 Lexus ES 350 has less then 4000 miles on the vehicle and the steering has malfunctioned twice and I am now unable to drive the car as it is part of the electrical system which continually freezes up making it inoperable. I purchased the car 2 months ago and as it was certified by Lexus this should not have happened. This is a potentially very dangerous situation. Fortunately I was in my parking lot both times this occurred and not on the highway.

Electrical System problem #6

I purchased my 2015 Lexus Es350 on Tuesday, November 25th, 2014. On November 27th, I was turning right into a parking space and the vehicle accelerated aggressively on its own causing the car to run over the concrete parking spot stopper and propel 200-300 feet until I hit a palm tree, stopping the car from entering a nearby lake. This caused significant damage to the car. My wife and I were in complete shock as I was unable to stop / control the car - I attempted to pump the brakes multiple times (leaving tire tracks) but the car continued accelerating until we hit the tree. We filed a report w/ the florida sheriff's department. Additionally, the day before (Nov 26th), I noticed the side mirrors on the car did not tilt properly when in reverse - the left mirror tilted down, the right mirror tilted up. This may be a result of the 'mirror switch block' but together with a few other mechanical issues, this leads me to believe the 2-day old car had some significant and dangerous mechanical / electronic issues. I have attached more information about the car and a picture of the parking spot where the acceleration occurred. Please contact me about appropriate next steps related to this significant defect.
