VISIBILITY/WIPER
While driving and using the air conditioning system coming out of the vents, the drivers side windows fog up and cannot be cleared with a rag or paper towel. This causes the drivers side windows to become heavily congested causing it virtually impossible to see out of the window and look into the drivers side mirror causing a major blind spot. This is especially troubling in the warmer weather. I’ve avoided two accidents because of the the blind spots this creates not being able to see out of the drivers side window and trying to look into the drivers side mirror to see if the left lane is safe to merge into to.

POWER TRAIN
Transmission will not shift out of 3rd gear. I was driving down the freeway in 7th gear doing 75mph when all of sudden the transmission threw itself into 2nd gear then to 3rd. It felt like I was driving over a very large boulder and my transmission was being ripped out from under the car. Then my check engine light came on. So I had it towed home. I went for a test drive and the car will shift 1st, 2nd then 3rd but won’t go to 4th. It just stays in 3rd, it doesn’t slow down, it continues to rise in rpm and speed but won’t go out of 3rd gear. It also will not go into the manual shift mode either. I have read online about thousands of others with the same exact transmission having the same exact problem. I almost was not able to control my car so it most definitely is a big safety issue. I had autozone run a scan on it and it popped up all of these codes. My dash had zero warning lights at all before the incident happened.

AIR BAGS, SERVICE BRAKES, VEHICLE SPEED CONTROL
Traction Control did not function when needed. I had my breaks and rotors replaced two days prior to the accident, which may have had an impact on the performance of the vehicle. Insurance representatives did look over the vehicle, as it is now in their possession. However, I do not feel as though they took the time to look into my concerns. There was no warnings on the Dash.

POWER TRAIN
I was driving on the freeway and suddenly my vehicle would not shift into third geer causing the RPM s to go up to 4-5. As I tried to exit the car started shuddering and I was almost hit by multiple cars. I finally was able to exit and stop to park the vehicle. No warning lights came on at anytime. I had it towed to my mechanic and was told that it was the valve body control. My car only has 86k on it and I have taken exceptional care of it performing all maintenace like clockwork. Was told replacement was 8,500.00 for entire part including the housing or 4,500 and use my current housing. My mechanic checked with infinity who said they knew of this issue, but there is no recall and the part is only under warranty for 1 year.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
A short in the hybrid system's fuse relay caused the air conditioning control unit and compressor to fail. This further shorted out the hybrid junction box causing the hybrid battery recharge and power management system to malfunction. Gas mileage was very adversely affected and the hybrid system would have eventually failed causing a potential safety issue where the vehicle could lose propulsion suddenly while driving.

STEERING
The backup camera (parking assist camera) image is flipped left/right. The backup video display shows the rear view of the vehicle and super imposes the direction of travel with turn based on the position of the steering wheel. With image flipped left/right reversing the vehicle is counter intuitive and does not match the super imposed directional guidelines. When this malfunction occurred I nearly crashed into a parked car while trying to reverse into a parking spot. There is no indication of the malfunction. Driver must realize the image is flipped and turn in the opposite direction. This is definitely a safety risk.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
-When braking while hybrid and engine system are attemping to determine the power draw the vehicle will propel forward increasing momentum of vehicle rather than braking. -Vehicle is available for inspection. -This issue can cause collision due to the sudden undesired propulsion of the vehicle, as well as addition unnecssary use of the braking system. -Dealer states this is normal condition. -Vehicle has only been inspected by dealer. -There are NO warning signs, indicators, or alerts. Issue first started around 35,000 miles. -In addition the drivetrain might also affect the ability to propel forward. While in slow speeds (10 mph and below) the vehicle the vehicle will stutter making take off difficult from complete stop. Additionally, vehicle stutters just the same while braking to come to a stop (10 mph and below) making it difficult to navigate a safe stop.
