2014 Acura MDX: sudden loss of power

Filed Sep 1, 2022 · Driver assistance, Steering · VA

On numerous occasions the Electric Power Steering, Lane Departure Warning, and Lane Keeping Assist problem lights illuminate on the dash and I lose all power steering. My car becomes extremely difficult to turn, particularly at lower speeds. This is a major safety hazard and warrants a recall. Had my wife been driving when this occurred she would not be able to turn the vehicle. This has happened on several occasions over the past 2 weeks. The car is being taken to the dealership tomorrow. Note: it appears that Acura and Honda have extended the warranty on several models for a similar issue, but not the 2014 Acura MDX.

Shortly after I purchased this vehicle in 2013, I noticed that their was a loud vibration coming from the front right driver's side near the wheel well when driving at speeds between 30 - 45 MPH. This vibration would occur intermittently. When I took the vehicle back in to the acura dealership, it was stated that they could not duplicate the issue. Two years later, the issue is still occurring and the dealership "can't duplicate". Additionally, noticed that there was bubbling of the front grill chrome paint. Later it became apparent that the left front passenger window panels were warped. Didn't make too much of a fuss about either issue, but in the summer of 2015, while running my car through a car wash, the panel popped off and began flapping in the wind. Returned vehicle to dealership and the window panel was replaced. At this time, I also informed them that the vehicle had begun to start exhibiting issues upon acceleration like it was struggling to gain power. You could also see the RPM indicator began to fluctuate when this issue occurred. This was also happening between 30-45 MPH. Dealer performed a diagnostic and said that they were unable to locate any issues. Driving the vehicle does not feel safe. I am afraid that it will lose power while I am driving and cause an accident. I have owned multiple acuras and the quality of this vehicle is by far the worst of any vehicle that I have ever owned.

Noticed bubbling paint on drivers side near back tire...emailed salesman with no response. Took car in for oil change, mentioned problem but paint had chipped off...took a picture to send to acura for their determination whether it was going to be repaired free of charge....asked again in septmeber...no answer yet...no phone call to date to let me know if covered or not. July 24 was driving when for no reason all warning lights came on with warning beep...called dealership. .. Was on my way to the airport for vacation and scared to keep driving..was told just a fluke and it would probably re-set...in august.took car to dealership and warning lights came on enroute...still on when I arrived...again told it was just a fluke happened again while parked with engine running in late august but noticed it was also idling quite high for no reason...called dealership again right away...left a message with no return call..it again re-set itself....in september I was driving 35mph and all warning lights came on, lost power and steering...called dealership, they had me look at message center but it did not say any code....took to dealership..told them I had been reading on line that other owners had same issue with no results...he said acura was working on issue....nervous that it will happen while driving on expressway and I lose steering and power.....tired on hearing there is no code and no answer....very expensive car to have this type of issue with no fix...thank you

While trying to accelerate during a left turn, the engine completely lost power and the accelerator would not work. All engine warning lights came on. We nearly avoided an accident by coasting into the center lane. I had to turn off the car and restart in order to gain the ability to accelerate again, but all the warning lights remained on. Drove it to the dealer, but they have yet to be able to determine what the problem is. This is the 3rd time this has happened - all during the first 5 minutes of driving during the morning. The last incident could have resulted in a serious crash.

The push button ignition switch was accidentally pushed, very briefly, while the car was still moving, with the gear shift in still in drive mode, the engine shut off. This could result in serious injuries or even death if the car abruptly changed speed, loss power to other safety control systems, loss power to the airbags, or loss power to the brakes.
