2020 Acura MDX Problems

The contact owns a 2020 Acura MDX. The contact stated that while idling and driving on several occasions at various speeds, there was an abnormal knocking sound coming from the engine compartment. The vehicle was taken to an independent mechanic to be diagnosed. The mechanic determined that there was internal engine rod bearing failure, and that the engine needed to be replaced. The contact believed that the failure was associated with Manufacturer Recall Number: 24-001. The manufacturer was notified of the failure. The failure mileage was 65,128.

The contact stated that after restarting the vehicle, while driving, the vehicle failed to properly accelerate, with a ticking and knocking sound coming from the engine compartment. The vehicle was later towed to the local dealer to be diagnosed and metal shavings from the engine bearings were found in the engine oil. The contact was informed that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact was informed that the VIN was not included in NHTSA Campaign Number: 23V751000 (ENGINE AND ENGINE COOLING). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 85,000.

The contact owns a 2020 Acura MDX. The contact stated that while driving at various speeds, the vehicle hesitated while accelerating. The contact stated that later, while parking the vehicle, the vehicle unintended accelerated and drove over a curb and crashed into a tree. The vehicle crashed into the tree, and the front wheels continued spinning without the accelerator pedal being depressed, and the engine was turned off. During the crash, the front end was severely damaged, but the air bags failed to deploy. The vehicle was driven to the residence and examined by an independent mechanic, and it was determined that the PCM had malfunctioned and there was a computer miscommunication between the engine and the transmission. The vehicle was later towed to the local dealer. The failure mileage was 45,000.

LKAS, forward collision, high beam all alerts are going off and have been told it's a camera system that gets over heated. This is not a easy fix and needs to be recalled to clear up the codes and alerts.

Multiple errors Lane departure and advanced driver support, ACC LKAS, auto high beam, and braking system. Looking into this more i see lots of people with the same issue failing front facing camera and not a cheap fix. Is there any current investigations into this problem or a software upgrade? I clear the errors and they come back once car is turned off and back on. If no fix to the current system there should be a way to disable LKAS and ACC without spending $2000 to replace the system.

The contact owns a 2020 Acura MDX. The contact stated that on six occasions the vehicle stalled and failed to restart immediately. The contact stated that while the idle button was on, the failure occurred. The contact was concerned about being in a crash. The vehicle was taken to the local dealer, where it was diagnosed, and two batteries were replaced, and a software update was performed. The dealer would be checking the software to be sure that it was operating as intended. The manufacturer was contacted, and a case was opened. The manufacturer provided a refund for the battery. The failure mileage was approximately 48,300.

The car had several warnings lights come on and immediately stalled out and stoped right in the middle of the road. The engine would turn over but would sputter like it was out of gas and would die after a few seconds. It stoped in the middle of a busy state highway in a curve. Luckily no one got hurt. I towed it to an auto service center. The 2020 Acura MDX suffered an in-tank fuel pump failure causing a low fuel pressure code (P0087). This model year is under a massive 2.6-million vehicle safety recall, but my specific VIN was omitted. It likely should be included before someone gets hurt.

While driving my 2020 Acura MDX A-Spec at approximately 63,744 miles, the vehicle suddenly lost all engine power without warning while passing through a busy multi-lane intersection. The loss of propulsion prevented acceleration and forced us to coast across traffic lanes to reach the shoulder, creating a significant safety hazard. The engine would not restart. The vehicle was inspected on 3/17/2026 by Lyle Pearson Acura (Boise, ID). The dealership diagnosed catastrophic internal engine failure with the following findings: spun rod bearing in cylinder #6, excessive metal debris in the oil pan, and bearing seizure to the crankshaft. The technician stated the failure pattern is consistent with the rod-bearing defect described in Acura Safety Recall / Service Bulletin 24-001. Although my VIN is NOT currently included in the recall population, the confirmed failure mode matches the known defect. This suggests the issue may extend beyond currently identified vehicles that are included in Acura Service Bulletin 24-001 and NHTSA recall 23V-751. The vehicle has a salvage title from prior cosmetic damage only; no engine, drivetrain, or structural components were affected. The vehicle has been properly maintained with documented service history. This failure represents a serious safety risk due to sudden loss of power in active traffic conditions, increasing the risk of collision or injury. I request NHTSA review this incident to determine whether additional vehicles should be included in the recall and to assess the broader safety risk.

Engine turns off while in drive or stopped at a red light/stop sign. It has happened 7-10 times withing the last couple of months, but 3-4 times within the last week. Out of the four times it happened, my family's safety was at risk, because the car was in drive, and could've caused us to get into an accident. During the other occasions, we were moving in reverse and stopped at a stop sign. Complaint was made with Acura of Bay Shore in Long Island, NY, at which time an update of computer engine was performed but issue wasn't fixed due to back-order part that needs to be replaced. Unfortunately, just yesterday (August 13, 2026) car turned off at light causing a road hazard to vehicles and my family stuck in a large intersection. Multiple engine lights turned on, but I was unable to turn the car on or move it. approximately 10 min later, I was able to turn the car on and move it to safe location. I spoke to Acura of Bay Shore, and it is a known issue but till this date, isn't fixed. Vehicle is a hazard and can cause serious bodily harm/or death. thank you

connecting rods came apart, needed a new engine. but outside of the recall

While sitting stopped at a red light, the brake pedal suddenly became soft and the vehicle began moving. As I rushed to depress the pedal further (all the way to the floorboard - which did not stop the car) the car rolled forward and collided with the car in front of us causing damage to both vehicles. If the other car had not been in front of us we would have rolled directly into heavy active cross traffic which would have caused significant harm to all inside. My daughter, niece, and 8 month old grand-niece were with me in the car.

The following issues occur on a 2020 Acura MDX with low 50k miles, maintenance was done regular whenever a maintenance schedule appear. For the past few years after purchasing the vehicle we started getting a non-start engine with the key fobs and automatic side mirrors did not open or close when parked. Brand new batteries were replace for the key fob and later the Car Battery and the issue occurs intermittently, this was brought to the attention of the dealership and each time (documented) that they were not able to reproduce when they turned off the vehicle, this was mid 2024 06-13-2024 and sporadically continues till this year 2026. The dealership did not test or trace the electrical system as they were told to reproduce the issue first as it will happen at that moment. A new recent event 2025 has also occur and was brought to the dealerships attention, a warning message indicating - Electric Parking Brake Problem follow by a Emissions System Problem will appear. This was also "reset" by the dealership and indicated it was safe to drive but event reoccurs every few months. A 2nd opinion to another mechanic indicated it can be the emergency brake system to be faulty and driving the vehicle when the message appears may cause an immediate stop, advised us to have the dealership reach out to the manufacture. No word from either for the past year. Any open recall for my VIN was done once we were notified and a New Car Battery replaced and new batteries in key fobs - issue continues. Please assist Thank you

There is an active Taillight (Lid Lights) Safety Recall (25V-259) on 2014-2020 Acura MDXs. When I enter my VIN it claims I am not part of this recall but there is sitting water inside my drivers side tailgate lid light assembly. It's only in the one, therefore I am unsure why my vehicle isn't listed/registered as part of this active recall.

The rear lighting on the left side of the tailgate was accumulating water. Even though it was part of a recall campaign, the period had expired. I had to replace it at my own expense. This could be a broader issue since similar cases may occur for others.

Acura has failed to repair my vehicle with a known recall for a year. I am told they're prioritizing symptomatic vehicles and have no ETA on all others. Why have a recall of a safety feature and not actually handle the recall timely. I prefer not to wait for an injury or incident before this is given the proper attention.

The windshield washer fluid does not come out of the nozzles. On a wintry day, there was a lot of dirt and grime kicked up from other vehicles and I was unable to see out of the windshield and it caused a very dangerous situation. Acura knows this is an issue but does not want to accept responsibility. There is plenty of fluid in the reservoir and I made sure the nozzles were clear of debris. The vehicle has not been inspected by the dealership or anyone else. There are no warning lights.

The contact leased a 2020 Acura MDX. The contact stated that the front driver’s and passenger’s side headlight covers became hazy, causing it to be difficult to see the roadway while driving. The vehicle was taken to the dealer where it was diagnosed that the headlight covers needed to be restored. The contact was informed by the dealer that the failure was a known issue. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was provided a case number, but no further assistance was provided. The failure mileage was approximately 36,000. The VIN was unavailable.

The power steering failed while driving, and multiple warning lights came on. This happened in the middle of a busy city street and came very close to causing an accident. When the car was restarted the power steering came back on line but failed again the next day. My wife and I decided it was unsafe to drive and had it towed to the dealer. The dealer told us that the "Wire Harness" failed and the Clockspring/Reel assembly had to be replaced. The total cost was $3,888.91. There were no warning lamps, messages or symptoms prior to the failure. This is definitely a safety issue. The dealer had no explanation of why a component like this should have failed. I contacted Honda and was told that there is no recall on this part and i should make a report to the NHTSA. This was a scary and distressing event. Please look into it and get Honda/Acura to issue a recall.

The rear seats for my 2020 MDX are making a loud squeaky noise. The car has all of 47,000 miles and this should not be happening. American Honda wants $4,467 to replace the rear seat that is in a newer car from 2020. I’ve already had to spend over $2,000 last year to replace the drivers seat motor. I’d like to know if this problem is prevalent in the 2020 MDX with other owners? I’d appreciate your insight. Thank you.

The contact owns a 2020 Acura MDX. The contact received notification of NHTSA Campaign Number: 25V259000 (Exterior Lighting, Interior Lighting); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. Parts distribution disconnect.

A federal safety recall was performed on the vehicle to install a rear subframe reinforcement kit. Before the recall repair, the vehicle operated normally and had no vibration at highway speeds. Immediately after the recall repair, a new vibration developed above approximately 60 mph. The vibration is felt primarily from the rear of the vehicle, occurs only while accelerating, becomes most noticeable between 60 and 80 mph, and disappears immediately when the accelerator is released while maintaining the same speed. The condition is repeatable and remains unresolved. The vibration creates concern for loss of vehicle stability and control at highway speeds because it occurs while the drivetrain is under load. No warning lights or diagnostic messages appeared before or after the repair. The vehicle has been inspected by both the dealership that performed the recall repair and an independent repair facility. To eliminate other possible causes, the front hub and bearing assembly were replaced and all four tires were remounted and dynamically balanced. Those repairs did not eliminate the rear vibration. The dealership attributed the condition to unrelated maintenance items, including tires, wheels, and brakes, but did not identify a defect with the recall repair or determine whether the rear subframe installation, rear differential mounting, driveshaft, or other components disturbed during the recall procedure contributed to the new vibration. The timing of the failure is significant because the vibration began immediately after completion of the federal recall repair and was not present beforehand. The component is available for inspection upon request. I am requesting that NHTSA investigate whether the recall remedy or repair procedure may have introduced a drivetrain or rear suspension condition affecting vehicle safety.

The contact owns a 2020 Acura MDX. The contact stated that the front windshield camera became inoperable. There were unknown warning lights illuminated. Additionally, the control arms failed. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The windshield was replaced with an aftermarket part at an auto body shop.

unknown, been reading that this brand/model/tires are having issues. Was wondering if I need to get them replaced before an accident. CrossContact LX Sport (continental) size: 245/50R20 102H

Safety issue for Continental Cross Contact LX Sport tires that were OEM tires on 2020 Acura MDX. I've had to have 3 nails removed from tires in just over 2 years of owning this car. So I've had tires inspected quite a bit. Also, every time I had oil changed (at Acura), they would rotate the tires and also inspected them. Every trip to Discount Tire, I was asked if I was rotating the tires because they noticed uneven wear. Now at 29K miles, the current rear tires are at 4/32 and front at 6/32. Latest nail removal visit, the discount tire rep mentioned he was going to research these tires and why they would be wearing this prematurely. He noted the rear tires had exceptional wear on the outer tread and noted this could cause the tread to separate. This concerned me so I researched myself and found many instances of complaints where this line of tire has failed due to that exact issue, the tread separated and their tire immediately went flat. The driver had to get off the road quickly and safely to avoid a wreck. Further research revealed that this tire HAS been recalled, but only for 3 specific sizes, which does not include the size of tire on my Acura. The complaints covered a multitude of vehicle brands that most likely use these as OEM and a wide range of sizes of this tire line. Including Acura, Audi, Tesla, Chevy blazer, VW, and Jaguar. I believe the whole tire line needs to be recalled, not just 3 sizes, for everyone's safety.

On May 30, 2024, the vehicle associated with the VIN associated with the report was involved in an accident. The vehicle is inoperable due to the seatbelt no longer working since the accident. The vehicle is at the collision center of my choice, and all repairs except for the seatbelt have been made. The collision center and I have reached out to American Honda Motor Company, Inc. and Acura several times. As of date, there has been no resolution and no estimated date of when a seatbelt will be issued by American Honda Motor Company, Inc. and/or Acura. I was told by an employee at American Honda Motor Company, Inc. that the seatbelt will become inoperable whenever the vehicle is in an accident or collision. I feel American Honda Motor Company, Inc. has and continues to produce unsafe vehicles and vehicles where repairs cannot be made promptly. Seatbelts are important, and I honestly believe seatbelts save lives. But, for a company to have a shortage of seatbelts with no estimated time of when one will be issued is unacceptable. And for the company to produce vehicles with seatbelts destined to not function after an accident is a problem. As a consumer, I would like this company to be held accountable for producing vehicles with problems and additional problems if the vehicles are in an accident. I've tried resolving this matter by contacting American Honda Motor Company, Inc., Better Business Bureau, and now NHTSA. I feel this is way beyond what a consumer should have to do.
