Recently my car has had a series lights come on including 4wd fault, pre-colliosion assist not available, service advance trac, hill start assist warning, and something with the brakes when in reverse. I took it to the dealer and they said it's something electrical that will need parts, and further investigation with removing the seats. That will be another day. Today, while driving with my son in the back, I was taking a u-turn on a busy street. The car acted like it switched into neutral (but didn't), and wouldn't accelerate, leaving me inching into traffic at 1 mph with cars going 40mph coming at me. Luckily I was not hit, but easily could have been. I drive almost 60 miles a day for work and this is a safety hazard not just for me, but my family too.

I am reporting a safety concern involving a delayed transmission gear engagement and delayed rearview camera activation. Intermittently, when shifting the vehicle from Park into Reverse or Drive, there is a noticeable delay before the transmission actually engages the selected gear. During this delay, the rearview camera also fails to activate immediately. Because there is no immediate indication that the requested gear has engaged, I have experienced situations where I believed the vehicle was in Reverse or Drive, but it remained in the previous state for several seconds. In some instances, the transmission engages unexpectedly after the delay, causing the vehicle to move in a direction different from what I anticipated. For example, after selecting Reverse, the vehicle may hesitate before moving, or after changing between Reverse and Drive, the delayed engagement can result in the vehicle moving in the previously engaged direction before finally shifting into the selected gear. This creates a significant safety hazard, particularly when parking, backing out of driveways, or maneuvering in areas with pedestrians or other vehicles. The delayed rearview camera activation further increases the risk because it prevents the driver from immediately seeing behind the vehicle while attempting to reverse. The issue occurs intermittently and without warning, making it difficult to predict. I am concerned that this condition could lead to a crash, property damage, or injury if the vehicle moves unexpectedly due to the delayed gear engagement. I request that the federal safety agency investigate this issue to determine whether it is related to a transmission, electronic shift control, or software defect affecting the safe operation of the vehicle.

The parking collision sensors started to act up. Its been replaced 3 or 4 times in the last year over the same problem and no one has tried to tell me how to fix the issue besides keep getting it replaced. People are at risk of getting hit or hitting a object that could be in the way of me reversing.

As I am traveling on the freeway or expressway, when I have cruise control active and I am in the far right lane the vehicle suddenly changes to the speed of the frontage road dropping my speed from 65 or 70mph down to 40, even tho I am on the expressway. It almost caused me to be rear ended because of the sudden drop in speed.
