The Horn never worked since I bought it in August 2023, iโve been in a countless near accident situations where I was rendered helpless. Iโve had several instances where I get locked out of my car because the vehicle would not read the key. I tried fix the issue because I assumed it was a dead car or key battery but the same problems kept happening shortly after. I became aware of the issue with the horn not working, when I recently purchased the vehicle. I tried to contact the ALM dealership salesman to report the issue and they told me he had recently quit. They mentioned bringing it back to the shop but it wasnโt guaranteed that the issue would be fixed.

Engine shots off while on the automatic stop and go idle . It is being doing it for a while but it is happening more often even with the auto idle off and it even happened at the freeway. It gives me a message to put it in park or neutral and turn the engine on manually. Making this a very dangerous situation because cars behind me donโt know that my engine suddenly shots off. Thanks

Unintended acceleration is happening. After about 15-30 minutes of driving, accelerating from a stopped position becomes very difficult in the sense that the vehicle does NOT accelerate when gas pedal is pressed. This can be extremely dangerous as you do not know when the vehicle will no longer accelerate and could get hit when crossing an intersection or turning onto any road at all. ESC warning light came on today and vehicle will no longer start but goes into auxiliary mode. This is not the first time, second, third, nor even 5th time a report on this vehicle has been made and with each report more issues are arising with seemingly NO fix in sight.
