THE AUTOMATIC COLLISION MITIGATION SYSTEM HAD A COMPLETE 100% LOCK UP OF MY BRAKES DURING A CROSS OF AN INTERSECTION . ALTHOUGH I WAS WEARING MY SEATBELT THE FORCE OF THE STOP THREW MY HEAD INTO THE STEERING WHEEL. IT IS A COMPLETE MIRACLE THAT THE CAR BEHIND ME DID NOT REAR-END ME. THIS SYSTEM ROUTINELY GIVES FALSE POSITIVES WHEN GOING AROUND CORNERS WHEN YOU ARE IN THE CENTER LANE AND IT BEEPS AND PULSES THE BRAKES. THIS TIME, THE CAR STOPPED COMPLETELY AND I HIT MY HEAD AND WAS LUCKY TO NOT CAUSE AN ACCIDENT. THERE SHOULD BE A WAY TO 100% PERMANENTLY TURN OFF OR ACURA NEEDS TO FIX THEIR SOFTWARE. TOO MANY FALSE POSITIVES AND ACTUALLY IS LESS SAFE WITH IT ON.

I think this recall needs to be expanded: Honda and Acura have recalled 2019 and 2020 vehicles including the CR-V and Accord for fuel pumps which can malfunction and cause the engine to lose power. My wife recently had her 2019 MDX stall on her in an intersection and she had to turn off the car and turn it back on so it would work. It sounds exactly like the below: âWhile driving, the vehicle shifts into Neutral, the transmission indicator comes and DTC P0657 (actuator supply voltage circuit/open) is stored. The driver will not be able to select any other gear until the vehicle is turned off and restarted. Update the PGM-FI [programmed fuel injection] software and the TCM software, clear any DTCs [diagnostic trouble codes], and do the PCM [powertrain control module] idle learn procedure.â - TSB 15-034 Additionally, May 23, 2021 we had an experience where the same MDX decelerated as we merged into traffic at I-30 and I-820 in Ft. Worth. I let off the accelerator going 60-70 MPH and then stepped on the accelerator to complete my merge and there was no power. Speed dropped to around 20 almost instantly. I had to completely let off the accelerator and depress it again to get going. Very scary situation considering how fast people drive on Texas freeways. These are two big issues Honda/Acura needs to address ASAP as both put consumers at risk of injury and possibly death.

THE VEHICLE SUDDENLY ACCELERATES ITSELF. THIS IS ESPECIALLY TRUE IN LOW SPEEDS. THERE HAVE BEEN NUMEROUS TIMES THAT I AM DRIVING SLOWLY IN A PARKING RAMP AND THE VEHICLE WILL JUST SHOOT FORWARD AS THOUGH I AM PRESSING THE GAS PEDAL, WHEN I AM NOT! I AM GRATEFUL THAT NO ONE WAS INJURED DUE TO THIS - BUT THIS IS DANGEROUS AND HONDA NEEDS TO LISTEN AND DO SOMETHING.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
5 Reports2% of totalPreviewing the first 2 complaint summaries.
My car was purchased with 12,000 miles and supposedly worn tires. Because of that, I went to the dealership to get new tires and an alignment since the car was always pulling to the right. My car has been at the dealership four times for the same problem, and they still haven't fixed it. My car continues to constantly pull to the right, and when I use the cruise control, it stays above the other cars to the right, causing it to suddenly pull to the left, deactivating the speed control and losing control. The dealership's recommendation is to stop using the speed control."

Forward Collision Mitigation braking randomly activates and slams on the brakes despite no cars/obstacles/items in front of it. I have luckily not been rear-ended, but I've had several close calls when driving in traffic (car noses dipping behind me). The dealership has so far been unable to replicate this issue and stated that unless they can replicate there is nothing they can/will do to fix the issue.

Vehicle Make/Model/Year: 2019 Acura MDX Component Affected: Forward Collision Avoidance / Lane Departure / ADAS (Front Camera System) Summary of Issue: I am filing this complaint regarding a recurring and dangerous issue involving the front windshield-mounted camera on our 2019 Acura MDX. After purchasing this vehicle and driving approximately 5500 miles in Las Vegas, multiple critical safety warnings began appearing on the dashboard, including: â¢âCollision Mitigation System Problemâ â¢âRoad Departure Mitigation System Problemâ â¢âLane Keeping Assist Problemâ â¢âAdaptive Cruise Control Problemâ These warnings occur continuosly. The warning lights wonât turn off, resulting in the complete shutdown of essential Advanced Driver Assistance Systems (ADAS). Safety Concerns: This camera-related failure disables major safety features designed to prevent accidents. The driver is left without automatic emergency braking, lane keeping, or adaptive cruise control. This is especially dangerous at highway speeds. Acura has not issued a recall, despite the widespread nature of this problem and documented cases in other hot-weather regions. Service Experience: We purchased the vehicle used from a Cadillac dealership. The issue began approximately 3 months after purchase. A mechanic confirmed that the front camera system is likely malfunctioning due to heat exposureâa known problem with this model. Why Iâm Reporting: I believe this is a safety defect that should prompt investigation. Acura appears to have issued Technical Service Bulletins (TSBs) but has not taken action to proactively notify owners or issue a recall. This defect compromises driver and passenger safety and puts others at risk.

The front camera responsible for forward collision warning and lanekeep has failed. The camera has part number 36160-TYR-A02. It failed on it's own but it could have been alot worse if it failed before a collision occurred. The dealer and independent repair shop said it was the camera code U3000-49 and this was an out of pocket repair. The symptoms include having these error messages on the gauge cluster. Adaptive Cruise, Lane Keep Assist, Road Departure, Collision Mitigation, and Auto High Beam Problem. At first it would intermittently show up but then after a while those errors would not go away.

Rear tail gate lift motors are overheating and won't open rear hatch. The motors will lift the gait for about 5 or 6 openings, then the gate will not lift at all. The vehicle has to sit overnight for the system to "cool down". Once it cools down, the tailgate will operate the next date, but will operate only once. The car has to once again, sit overnight, in order to lift the tailgate 1 time. If the motors of the gate are overheating, this is a safety potential fire issue. At this time I am being told the motors are on back order, and I have no manual override in this vehicle to lift the tailgate hatch. If the same motors are being put back in the vehicle, without any modifications, this will not suffice.

TIRES
1 Report0% of totalPreviewing the first 1 complaint summaries.
Continental Crosscontact LX Sport 265/45R20 104H Tires have about 33,275 miles on them (rotated regularly) and one of the tires has a huge bump in the tread. The belt has separated from the sidewall. From what I've read, there are recalls on this tire, but not for this particular date that these tires were made. With it being on the front, it makes the steering wheel shake and I'm scared to drive it anywhere except to the tire store.
