2014 Acura MDX: lane keeping assist jerks the wheel

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.

After driving on highway for 20mins, when diving on city street or at low speed, transmission failed to shift gears, lost manual shift control also, vehicle kicked back and forth strongly with very loud sound when driving and shifting automatically. Engine light is on, says emissions system failed, lane departure warning system failed, transmission failed. After restarted(multiple times), transmission still not working properly, very rough shift, whole car kicked and shaked when gear up. If press gas harder, gear will not go up on time, RPM will go very high, speed remains slow. If press brake, gear shifts down too early and engine will slow the car in sudden. Cannot drive safely or on highway at all. Same issue happened in january 2019, dealer changed solenoid control assembly under warranty, but same thing happened again in june and july 2020 and got worse at this time. Six speed at transmission in 2014 acura mdx. Read a lot of reports of the same issue about this transmission from other owners.

Defect shows as immediate loss of toe alignment in both front tires, lane keep assist computerized feature in unable to turn steering wheel right, and steering wheel position sensor is unable to remain fixed at zero. Steering wheel position sensor: forces the vehicle into oncoming traffic by automatically during front wheels two and five degrees with maximum turning force applied when the road presents any combination of curved, tilted, and bumpy condition. Steering wheel hand sensor ? Computer applied over-steer forces the car left or right several degrees depending on hand position. Ids: three settings force steering wheel several degrees left or right during braking depending on last applied steering adjustment. When the road is a combination of curved, substantially sloped, or bumpy the computer will apply maximum computerized turning force to move steering wheel up to 45 degrees left into oncoming traffic even when the road slopes and/or curves away from oncoming traffic. A series of software command conflicts and overrides between ids, steering wheel position sensor, steering wheel sensor for hand position, radar, and road position sensor, and other-vehicle sensors routinely cause the computer to perform unintended drive into incoming traffic with maximum computer applied force. Manufacturer refused to provide dealers computer diagnostic equipment that aligns steering wheel sensor with navigation computer, radar, internal/external sensors, ids, and steering wheel hand sensor unless the consumer is willing to pay $700 in equipment transfer costs. Manufacturer demands dealers deny service or avoid writing work orders that contain any indication of a problem with steering wheel sensor, radar, computer-integrated hardware, or ids. Instead verbalize computer-related issues with repair techs to avoid regulatory reporting and california lemon law requirements.

The car has periodically shown an alert indicating an imminent activation of the automatic braking safety system when nothing has been in front of the car. Today, it did it this morning, and then later in the morning, while driving 30 MPH, the car cut off, making it inoperable and it stopped in a travel lane of a busy road. We were able to re-start it long enough to navigate off the road to a safe location, and it promptly cut off again. After that, it wouldn't run for more than 30 seconds. Every warning imaginable (power steering problem, lane keep assist problem, emission system problem, vehicle stability assist problem, hill start assist problem) was displaying on the information panel in sequential order. We had the vehicle towed to an acura dealership for inspection/repair.

My brand new mdx has had issues with multiple warning lights appearing on the vehicle when starting the engine. This includes check engine warning, lane departure warning failure, power steering issue and possibly additional warnings. The vehicle did this the first time when I took delivery of the vehicle and at that time, was resolved by fixing a loose plug. Then it did it again when I was supposed to pick up my vehicle for a couple minor trim repairs saturday, december 7, 2014. The vehicle is still with service and they have yet to figure out what is causing the warning light issue. I was advised that they are in touch with acura's tech line on this and they hope it will be resolved soon. Additionally, I completed further research on this and noted that other owners are experiencing similar problems with warning lights appearing on their 2014 mdx vehicles. Here is an online reference that I found where owners have posted comments on this: http://www.mdxers.org/forums/94-new-2014-acura-mdx/63666-2014-mdx-issues.html.
