My vehicle has a battery issue, we replaced the battery twice in two years still the issue might happened again and again. Once the battery start draining energy, everything start blinking and car stops all of a sudden in the middle of the road because of brake assistance problem. All the system errors come up. It is very scary to drive the vehicle with my kids inside. All system in car works with battery. service center told me that this kind of cars needs bigger battery and company only put small batteries in the car. Company don't put warranty on battery if it is replaced under car warranty. My car is only 33 months old and i have to change battery twice, It might happen again. Please help me to resolve the problem. It looks like factory problem that company do not make sufficient batteries to satisfy the vehicle needs. I have attached the pictures of safety lights.

I am filing a complaint regarding my 2022 Acura MDX Type S with approximately 70,700 miles. The vehicle developed a suspension system warning, and upon inspection by an Acura dealership, I was informed that the suspension stroke sensor and floor wiring harness are corroded and require replacement. I was quoted approximately $12,000 for the repair. This failure is extremely concerning because the vehicle is only a few years old and this type of corrosion affecting a major wiring harness should not occur under normal operating conditions. The affected components are part of the suspension system, which directly impacts vehicle handling and safety. Due to the failure, the suspension system may not function properly, potentially affecting ride height, stability, and overall control of the vehicle. This raises safety concerns, especially at highway speeds or during emergency maneuvers. …

I've recently been in touch with an Acura dealership about my vehicle's wireless charger not working. So shortly after purchase I made my complaint that the wireless charger pad is not charging my phone. They've replaced the pad but still not charging my Samsung ultra 22+ unless the car is parked and sitting still. They've asked me to allow time for researching the issue and taken all the make model details from my phone. Well sadly a few other things recently became noticeable to me as well and I will be following up with the dealership to address them as well as I'm not satisfied with my truck and the many issues I'm experiencing. 1) Jerked when coming to a stop to reverse into my driveway 2) A loud Thud noise could be heard inside my truck although I had the radio on when switching from park to drive or drive to park. …

May the water leak causes fire . I have many issues going on on my new 22 MDX 7k miles on it , the car is acting crazy no keyless entry working, remote is not working, I called many dealers after they checked it they said we have to keep the car for few days because there's water leaking on the driver side, it was a shocking for me that a brand new car having that, I called the worst company ever Acura and i told them i need a replacement or buy back I'm not agree to fix a brand new car and go through this hassle for years, they was very aggressive and not professional or fair and the case manager hange up on me (Jassica) she refused to let me speake to her manager or supervisor, she said just have to leave the car at the dealer for few days without loaner or reimbursement!! Is it fair ?! …

All electrical systems failed while driving around 30mph, Power steering failed, power brakes failed, lane assist failed. We were at high risk of a crash due to lack of control of the car while driving. We were lucky that it happened on a flat road and we were able to manually pull over to the side of the road. The vehicle was inspected by the manufacturer and we were told that the car did show all the steering angle sensors did malfunction and fail. They said there is no known cause. They just recalibrated and reset the sensor and said it now is ok "at this time." There is no guarantee that the problem won't happen again and put my family's life in danger. Prior to this incident we repeatedly got the "BRAKE SYSTEM: Brake system problem, Brake performance may be reduced, See your dealer". We took it into the deal and was told nothing is wrong with the car and this is a known issue. …

On [redacted] I headed out for an event. I had been driving for 8 minutes when I lost the ability to steer, the Brake, TSA, and Steering system warning lights flashed on the dashboard and I immediately turned onto a side street. One message stated to contact dealership immediately, DO NOT DRIVE. The car was towed to Mungenast St Louis Acura. It was scheduled for service on Monday, June 23, already, so this was perfect. It was determined the battery failed. My concern is that prior to this event the vehicle's warning system gave no indication the battery needed attention, was low in power, or anything else related to the battery. I was on a busy street however, this event could have been very much different had I decided to take the highway to my event.

As I was turning right (slowly accelerating from a complete stop) into a shopping center parking lot, I was entering into the lane behind a vehicle that had just passed in front of me (and was headed in the same direction I was going to turn). My 2022 Acura MDX Low Speed Braking Control system engaged for no reason. The breaks slammed hard bringing the car to a hard, sudden stop, and I thought I had been rear-ended by the car behind me. I pressed the gas slowly again and was able to pull into a parking spot and checked my back bumper...PERFECTLY FINE! I googled the issues I experienced and found this is a common problem! This is a dangerous problem! Please hold Acura accountable to fix this issue! For now, I have to remember to turn this Low Speed Braking Control System OFF EVERY TIME I power on my MDX! I am now scared to drive my car!

I was driving my car on the interstate and momentarily stopped due to traffic congestion. My engine idle stop feature was on and engaged as expected for the short stop, but the vehicle then stalled when I attempted to drive. There seemed to be an electrical issue with various lights coming on the dash to indicate a problem. I could not get the car to restart and was stuck in the left lane with cars then going around my stalled vehicle. I called 911 for help after I could not restart the car after 3 attempts. After approximately 5 minutes, I pressed the ignition button again, and this time my car was able to restart and drive normally so that I could exit the highway.

All safety system alerts appeared while driving on the highway saying there were failures with all of the safety systems. Electronic steering suddenly stopped working and vehicle slowed down forcibly until its stop in the middle of the highway. I had to call roadside assistance to get the car towed to the dealership. ALL ERROR MESSAGES CAME ON, THE VEHICLE ELECTRIC POWER STEERING,VSA , HILL START ASSIST,TRAILER STABILITY ASSIST PROBLEM, COLLISION MITIGATION & VEHICLE KEPT STOPPING ITSELF WHILE DRIVING, ROAD DEPARTURE.
