I was approaching a stop light on a busy street on a very bright day and did not see that the stop light I was approaching had turned red. When I realized it was red, I braked rapidly of course but still going at a pretty good speed I hit the stopped car in front of me. The collision was between drivers side of my MDX and right rear of a medium-sized white Jeep. My 17 yr old son was in the front passenger seat and his air bag deployed, however my driver bag did not deploy. Both seat belts locked up. The impact was very strong on driver side given that is where we hit. Fortunately, my seat belt kept me from hitting the windshield. My only injuries are neck ache, head ache, seat belt bruises, and ringing ears. My concern is for future use of my car. If the driver air bag did not deploy given this hard of a hit, I do not believe it will deploy in any collision. I filed a complaint with Acura requesting them to inspect the airbag and black box to determine why it did not deploy and they said that airbags are designed to only deploy when needed and in this case the cars computer determined it was not needed hence there is no reason to inspect it further. I believe that if the airbag deployed on the passenger side where the impact was less then the air bag should have also deployed on the driver side. My insurance adjuster also supposedly requested Acura to inspect the vehicle and they also did not get any favorable action from Acura. Honda/Acura of America returned my phone calls twice and simply said there is no supporting information indicating that the airbag or cars computer should be investigated. They also did not ask any questions about the accident in which additional information could be provided. The estimated repair on the car is over $12K.

I recently bough the car and I am now regretting it because the 9 speed transmission is very sluggish and doesn't provide power when needed. In the morning when I start the car the car just lags the power until I press hard on the gas pedal. We took this on a road trip to California from Utah and at times I feel like I don't have ample power to pass other drivers and it takes a few seconds to think before it does anything. I have an appt scheduled with Acura tomorrow to see what can be done to fix this otherwise I am taking this SUV back to the dealer for another car. I am very disappointed with Acura for making this kind of a transmission and I wish I have kept my BMW.

Acura is refusing to address a serious problem with the engine and power train with the vehicle, this may have already caused accidents on other cars in other states. Please see the historical data which gives a complete audit of the issues I have had. 9/22/18 11 days- vehicle taken to the dealer and dropped for service, punch list of issues since purchase that needed addressed. Alignment report is signed off on 9/24/18, battery check 10/1/18, service was started on 9/29/18, car sat for a week with no service attempt made. Oil stains on roof liner were left there and was told they would not clean them off (later proven to be mechanics grease by merrillville) and spider was my problem not theres per 'rob' in service. Issues the car was taken in for. All of the below service was comleted in 5 miles according to odometer readings. On 10/12/18 I took the vehicle to Acura of merrillville per 'anthony' from Acura client care to have it checked. I drove it with the tech and the tech was able to validate a lot of the issues right away. It was returned to me on 11/2/18 22 days on 11/24/18 I returned the vehicle to Acura of merrillville due to the transmission issue returning, also addressed a couple of issues. Car returned on 11/28/18 4 days vehicle loses power when shifting to accelerate, often have to downshift using paddle shifters to make power or car acts like its going to stall. Brakes do not function unilaterally, hit the brakes heavy while in traffic and the back will begin to come around as though one of them does not grab. Engine loses power when in traffic it struggles to accelerate which could cause a crash if needing power to accelerate onto a expressway from an entrance ramp, or anywhere that requires power to move the car.

When driving down the highway the car picks up a guardrail and thinks it is an object. The automatic braking system turns on and there is a grinding brake that gets applied while you are doing 65 mph on the highway. It's really unsafe.

Next day.while braking to park, car wound not stop and rolled into field. My wife was with me to confirm it was not me pushing the gas petal by mistake.

Brakes are too soft. Main brake pump has been changed in few days after delivery. Still brakes are soft and have long range for pedal to go down. Kind of do not feel the resistance. Very uncomfortable and do not feel safe.

- Chestnut Hill, MA, USA

The vehicle was in motion on a city street. While approaching braking and stopping traffic, the vehicle was coasting at about 20-25 mph when the brakes were applied. The brake pedal would not depress and the car continued to approach stopped traffic with no change in speed. The vehicle was maneuvered into snow along the side of the road to slow to avoid a collision, when the speed dropped down to <10 mph, it was maneuvered back onto the drive pavement and braking was effective. There were no obstructions on or near the brake pedal. The pavement was dry and clear. There was no skidding. The weather was cold (approx. 22 deg F) and the car had been sitting out overnight. The car had been running for approximately 10 minutes and driven for 5 miles before the incident occurred. The brake pedal felt occasionally "stiff" for the next couple of miles. It was then taken to a dealer for inspection, resulting in no visible or discoverable findings or defects. There were no warning lights or indications and no faults indicated in the computer.

Forward/front collision mitigation braking system didn't engage enough to reduce or avoid impact of the collision. My vehicle took a right turn at about 20-25 mph and travelled less than 2-2.5 car length before getting onto the curb and hitting an iron pillar about 2 feet high on side walk. It was a side frontal collision and the passenger side front wheel directly hit the iron pillar. The vehicle speed wasn't reduced to mitigate impact/damage from the collision and vehicle took full impact of the collision. The forward/front collision mitigation braking system must be evaluated to assess suitability to avoid collision with objects of low height.
