problem #10

Aug 132019


  • 10,000 miles
While driving, I received the message "advanced driver support system: U3000-49". this is the second time this error has appeared on the console. First time this had occurred was on 9/28/18 and again on 8/13/19. The dealer says I dont drive the car enough and in turn the battery for the camera does not have sufficient charge. Every time I bring this car in for an issue they reset the error message and inform me to let them know to come back if the issue appears. This happened with my trunk and my jerky transmission. On another note, I have had issues with a choppy transmission. The car jerks from 1st to 2nd everytime. They know about the problem but refuse to fix it. The 2019 models dont have this problem as I test drove. It is a safety issue because when you press the accelerator it gives a jerk and in the winter if you are not prepared it can catch you off guard.

The brand new SUV (2017 Acura MDX AWD tech package) has about 7000 miles and for the last 300 miles it is having problems which are critical safety issues, when the gas is slightly pressed to increase speed in a moving vehicle. This issue is seen at least once a day or once in 2 days. The SUV has auto braking feature and it is definitely not related to that. 1. the car brakes by itself (slightly slowing down for 1 to 3 seconds) 2. the car speeds up unexpectedly and then brakes by itself. I took in the car few times to the Acura dealership and they said they did not see any issues in the computer. So now I am very concerned and worried to put my family in the car.

Car caught on fire in the middle of the road. I was inside of the car with my three kids, my husband was driving, the car started smoking, we stopped in the middle of the road and everybody ran out of the car and the car caught up in flames, we heard an explosion, the police officers and firefighters arrived and they stopped the fire. They filed a report with city of issaquah #18-09696. We called the dealership and Acura customer relation and they didn't want to go see the car and check what caused the fire. Firefighter mentioned it could have started in the engine. From my point of view, this was a manufacturing defect and should be covered by the car's warranty. I would like to request for a compensation, the money spent on the car so far.

Multiple errors in safety warning and action systems such as the collision mitigation and warning system. For example, while driving on a four lane highway (undivided, no head-on traffic), my vehicle was in the far-right lane, 800-900 feet behind a truck in the left lane. The truck began slowing and moved into the wide left-hand turn lane leading to a signal controlled by a traffic signal. When I was about 2-300 feet behind the truck, now stopped (awaiting a left-turn light), the collision mitigation system flashed the word ┐brake┐ in the heads-up display and went into full braking mode to the limit of the anti-skid system. There was no other traffic on the road within 3-3500 feet of the intersection. This has happened numerous times where the collision mitigation system went to full braking with no other vehicles possibly representing a danger. Numerous other warnings of the sensors alert at random. Most recently, while stopped at an intersection with my foot on the brake ┐ the engine idle-stop system working (I.e., the engine was not operating) ┐ we received a warning to ┐brake┐ and warning of approaching vehicles (which should not happen). We frequently get warnings of non-existent trafffic approaching from behind while sitting in a parking slot, transmission in park, parking brake on (or off, both). Cruise control was not used in any of these cases. There are dozens of other false warnings, both audio and visual, that do little more than to train us to ignore them, not a good attribute of any warning system. Backup collision sensors frequently alert to hazards which cannot be seen: I┐ve actually shut down the engine, get out and looked to see if something like a shopping cart might have rolled into the vehicle's path, only to find nothing whatsoever behind the vehicle. Warnings are both in visual (word/graphics) and audio form.

On several occasions as I reduce speed, the car suddenly accelerates when I release the break to start accelerating again. The acceleration happen when you are going at slow speed. The first time I took it to the dealership it had happened in 4 occasions and I had atributed the incident to lack of experience in driving a new car. Because it happened in front of my daughters school ┐ and in theory I could have actually killed a child ┐ I promptly deliver it to the dealership. During the test drive with the technician, the car changed gears from the comfort mode to sport mode on its own. Because it was a safety issue, they informed me that an engineer from Acura would come and inspect the unit. After a week with my car, they just did an update into the transmission software - and informed me they were unable to recreate the issue. Thirty three days later┐ while dropping my dad at his dialysis ┐ at a turn - the car went form 3 miles to 25 miles, and it was fortunate that it was 5:45 in the morning ┐ since I could certainly would have cause an accident considering I almost ran a light. I called the dealership and on February 1, dropped again the vehicle at the dealership. 11 days later I called back to follow up and was informed by the service manager that Acura should have contacted me on Friday February 9 to let me know that they would be sending an engineer to check the vehicle again. Our concern is that this is a safety issue documented on two previous complaints in this forum, that constitute a serious risk for my family and community. At 11:00 am on February 12 I have yet to hear from Acura although they are aware of the issue.

Occassionally, the yellow brake alert goes off when driving around a right hand bend with a car coming the other way. There was absolutely no chance of a collision where braking was necessary. Also, I have had once instance where the car applied the brakes and brought the car to a complete stop when it was unnecessary.

It was 46░ outside when I was driving down I-10. My sunroof exploded with no apparent cause. Only car on interstate at the time. Not passing under overpass or following behind any vehicle that could┐ve thrown rocks. The break in the sunroof was in an upward fashion, as if it broke from the inside out (as if related to increased pressure). The piece of glass that was broken was a large sheet, still intact. It seems if an outside obstacle (such as a rock or debris) would┐ve caused the sunroof to shatter, the glass would┐ve been in many more pieces/shards. I took it to my dealer who said it ┐must have┐ been a rock and they wanted me to file an insurance claim. After I refused, they offered me a ┐good will warranty┐ to cover the cost but never did admit that this issue was more than likely related to a manufacturer defect.

I was driving 70mph on AZ state route 51. I heard a loud bang, like a gun shot, and a sudden noise like turbulent air and highway noise. As I slowed the vehicle I looked around to see if there were any broken windows which there weren't. pulling over and inspecting the vehicle I noticed 2/3 of the moonroof was missing and a few pebbles of plate glass on top of the inside cover. The remaining glass was angled up like it had been sucked up not deflected down from an impact. I was a navy fighter Pilot and this is the same sequence of events I experienced with the loss of a canopy and sudden decompression. I have a master's degree in aerospace engineering and I know the location of the moonroof is a low pressure area like the top of an aircraft wing. There were no other vehicles in close proximity, no objects flying off the road, nor was the vehicle under an underpass. This is a combination of a design flaw and possibly a defect in the moonroof glass. The vehicle is 3 months old, less than 3000 miles driven and the moonroof has never been opened. Acura takes no responsibility. This is a safety hazard as a less experienced startled driver could be so distracted as to cause an accident. The fix is a wind deflector in front of the moonroof. I am having one installed at my expense by the Acura. I would prefer a metal sunroof or a factory roofline modification to deflect the airstream and prevent the low pressure area causing this problem. Googling moonroof explosion yields numerous incidents from multiple manufacturers. There needs to be a fix before a fatality occurs. Captain, usnavy(ret)
