I BOUGHT THE VEHICLE IN FEBRUARY 2024 FROM A CERTIFIED ACUARA DEALER. ON DECEMBER 26TH THE VEHCILE SUDDENLY WENT INTO NEUTRAL MODE AND WOULD NOT CHANGE INTO ANY OTHER GEAR. THE CAR WAS SHUTDOWN AND RESTARTED ABOUT 5 MINUTES LATER WITH THE DASHBOARD FULL OF WARNING LAMPS AT START UP. I ATTEMPTED TO MOVE THE CAR FROM THE ROADWAY BUT THE GEAR SHIFT CONTROL WOULD NOT WORK IN ANY GEAR. TRANSMISSION WARNING LAMP CAME ON. THE CAR WAS TOWED BACK TO MY HOME ADDRESS. THIS CAR WAS ACURA CERTIED USED. IT HAS BEEN MAINTAIND BY A HONDA SERVICE CENTER. ACURA, HONDA AND THE ACURA DEALER LOCALLY ALL HAVE STATED THERE ARE NO ISSUES WITH THE CAR OR WARRANTIES FOR THE ISSUES. THE CAR HAS 74582 MILES. BASED ON ONLINE FORUMS THIS SEEMS TO BE AN ISSUE WITH MANY ACURA MDX OWNERS. ACURA AND HONDA AMERICA ARE NOT ACEPTING THEIR PRODUCT IS DEFECTIVE. LASTLY, WE NEARLY AVOIDED BEING IN A SEVERE ACCIDENT DUE TO THE SUDDEN STOP ON THE ROADWAY

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, SERVICE BRAKES
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.

ENGINE
I had purchased this vehicle and was not aware there was a stop sale on this vehicle model. I took the 2020 MDX to the dealer to get the recall service done, the connecting rod bearing and fuel pump issues. They were done back in March of 2024, j had taken the vehicle back to the dealer over 5 times for issues with stalling and trouble turning back on as well as engine noise, ticking and stalling. The dealer “cannot replicate” the noise all of sudden, but was initially able to hear the noise and stated “ it’s probably fine, but bring it in if it gets worse” this issue happened after the recall service was performed and the vehicle has never been correct since, I believe there is engine damage caused by the needed recall service.

ENGINE
While driving on an interstate highway at 73 mph, under cruise control, at night, as the road started to incline up a hill my vehicle started losing power. The highway is two lanes each way, and I was in the left-hand lane passing a slower vehicle that was in the right-hand lane. There were cars behind me in my lane. When my car started losing power, the check-engine light came on along with some other indicators. I attempted to maintain speed by depressing the accelerator, but the car continued to slow down. It was nighttime when this happened, on a pitch-black highway that had been freshly paved. I was able to finally get behind the car I had been attempting to pass and was then able to get into the emergency lane and stop. My car was making a ticking noise. I turned off the car, opened the hood, but it all looked fine. I looked under the car - there were no fluids running out of the car. I checked the oil, and it was at the full mark on the dipstick - I had changed the oil about 1000 miles prior to this event. When I took the car to a local Acura dealer, they told me that the noise I was hearing was "rod knock", and that it would cost about $8000 to repair by purchasing a short block and having them install it. When I started researching the issue I learned that some 2016 Acura MDXs have a known issue of incorrect rod bearing size, but that my vehicle is excluded because it was evidently manufactured before a certain date. My car has only 125,116 miles on it. It is maintained meticulously. Please investigate.

ELECTRICAL SYSTEM, ENGINE
Vehicle always smells hot or as if something electric is burning in the engine compartment. Have always had scheduled maintenance and have taken it in on time for all oil changes and maintenance to be performed. Have asked for this to be checked at that time and when the smell has become over powering. Engine lights have popped up and then all lights have shut off two separate times previously to the point where I had to turn off the vehicle. I have taken it to two dealerships and another mechanic to look for the cause. They are not able to determine the cause but recommend I contact Acura as this sounds like a warranty issue.

ENGINE
This occurrence with the vehicle happened in October of 2023 and I no longer own it. The only reason I'm reporting it today is because of the news reports I've been seeing about a possible investigation into the exact issue I experienced. I started to hear a knock from the engine that got progressively worse over the course of a week. I made an appointment to have it looked at, but before I could even make it to that appointment multiple dash lights and warnings started showing up on the meter combi. Engine light was the first to appear followed by the transmission light, then the vehicle went into "limp mode." It wouldn't go over 30mph and eventually just shut itself off; every warning lamp on the dash was on. It was towed to a local Acura dealership where the service tech diagnosed the issue and stated it was a connecting rod bearing that had worn prematurely and there was movement in the piston. I had them check for a recall then and my VIN was not on the list so I proceeded to source a motor and have another shop swap it for much cheaper. That being said, I would very much like to be reimbursed for the costs I incurred. I have multiple documents and at one point had a video that the dealership tech sent me showing the defect. Not sure if they can provide that now or not.

The engine started to make noise, drove it to the Acura Dealership. The engine seized at the repair bay. The technician initially said they just had a recall on these engines then after looking up the ID notified me that the blown engine was not covered under the recall. After several calls to Honda corporate customer service they informed me that they knew it had a faulty engine however it was not under the recall and they didn't have to repair or replace. I paid the dealership to install another engine at my own expense.

We were traveling far from home on I-44 in Missouri when our 2020 Acura MDX experienced a total engine failure. An engine rod broke and pierced the oil pan causing a sudden loss of engine power. I believe this is related to the NHTSA Investigation #RQ24013, even though the Acura dealership had performed the recall service for this issue a couple months earlier. I suspect the recall service was either performed incorrectly or that a part was not tightened properly, ultimately leading to the engine failure.

FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
There is a recall on my 2020 Acura MDX and I have been going to the local Acura dealer to get the part for the last 6 months and every time I go they tell me they are still waiting for the part. Periodically, the vehicle lurches while I am driving causing a major back and forth tugging and jerking. This is very unsafe. I am demanding that Acura prioritizes my need to get this fixed. I do not know if the jerking of the vehicle is due to the recall, but regardless, Acura needs to do the right thing and send the part to the Acura dealership so I can get this fixed. No Acura dealer in my area says they have the part. I am on a "waiting list." My car last did this jerking motion on 12

Our 2016 MDX starting peeling paint off the roof. Acura said they extended the warranty for this known defect for an 8 year period. Since this problem just happened we are outside the 8 year extension. The internet is full of similar stories of people like us who have the paint peeling after the bogus 8 year extension. Acura said they aren't responsible. This isn't right.

There is a clear engine knock. I have a recording of it both on video and audio, my engine performance and gas mileage has gotten worse. I picked up on the sound about 6 weeks ago and called (Mueller Acura), said I would have it checked at the next oil change. The dealer (Mueller Acura of Merrillville) has had my Acura MDX, for two days two weeks ago and for the last 7 days, currently. The didn’t tear down the engine completely. But they told me they had their master mechanic and Honda’s (from another shop Team Honda) Master mechanic came down and used a camera and I have a bad tensioner, bad rockers, and a bad cam shaft. I’ve been speaking with an outside mechanic who is a Honda certified Master mechanic who now runs an independent shop. Acura, says I have a bad camshaft, bad rockers, and bad tensioner. They said I need all of those replaced as well as the $3000 100K service. They are deeply discounting what they quoted me because I’ve documented well and made so many trips out there to physically show them the engine knock (right now they want $3606 to fix and then they will listen again). They finally heard it at the back of the engine. I’m in a rental and it’s costing me daily. The independent shop says the correct answer is you have a bad engine and they need to check the crank shaft, the head, and the rod bearings, in addition. He said if I changed the oil myself I would probably see metal particles in the oil and if I fix it I’m wasting my money as the entire engine is in need of replacement. It only has 86K miles on it and should not have these issues. I don’t think I should have to pay, and I need my vehicle back. I’m now without a vehicle and they are demanding I give them an answer by Monday at 7am on whether or not I’m fixing it. They won’t put anything in writing as they want to keep it kept quiet until I make a decision. The service manager is now trying to talk me into trading but not at their dealership. I feel like May need to contact an attorney.
