2018 ACURA MDX Complaints

Rob bearing recall was performed on a 2018 Acura MDX at around 78,000 miles. After a long ordeal with Acura because the recall had not yet been extended to the 2018 MDX's yet, Honda agreed to replace the motor. The new replacement motor has already seized again with only 30,000 miles. Dealer has taken motor apart and confirmed it is the same rod bearing issue as the recall. So the new motor that was replaced must have the same issue. After further investigation, it also appears that the Acura dealership that replaced the motor, did not tighten or replace many bolts during the repair. I have attached pictures of missing frame bolts, engine bolts, and the spun rod bearings.

Front camera stopped working at 65 000 miles. Seems to be a faulty part as many Hondas and Acuras have the same problem and the dealer wants over $2000 to replace a $700 part that sounds like less than 45 minutes to replace.

Odometer Fraud. The contact purchased a 2018 Acura MDX. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the mileage was 85,000. The contact stated that on the day of the purchase; after refueling the vehicle and then attempting to pull out of the gas station, the Emissions, check engine, and parking brake warning lights illuminated on the instrument panel. The contact took the vehicle to an auto repair shop, and had the vehicle scanned and then diagnosed, DTC: P0158 (Oxygen sensor Circuit High Voltage, DTC Severity 2 of 3, T0159 Oxygen sensor Circuit Slow Response (Bank2 and Sensor 2), and an Electric Parking Brake Failure were displayed. The scan indicated that the vehicle was subjected to odometer fraud. The contact reviewed the paperwork and received it at the time of sale and became aware that the mileage stickers, along with other indications that the documentations were false. The contact retrieved a Carfax Report and discovered that the actual mileage was 225,802. The contact reported the odometer fraud to the Police Department and was informed that the dealer was known for odometer fraud. The Police also informed the contact that there was a case and a warrant already issued.

While driving the car, several warning lights turned on all at once, saying that the following components were disabled: Lane Keep Assist, Adaptive Cruise Control, Automatic High Beams, and Collision Mitigation Braking System. Not being able to use these features is more dangerous, not to mention that the warning lights associated with their disabling are distracting (making it likely that, if a more serious warning was flashing, it would not be noticed by the driver) and cannot be turned off without an expensive replacement. Yes, the problem was confirmed by a trusted mechanic (the warning lights will not turn off so it's not hard to confirm), who indicated that the radar camera needed to be replaced. No, the component has not been inspected by others. There was no warning of the problem.

Emission systems problem and parking brake problem lights came on simultaneously. Mechanic has not been able to figure out the problem Replaced vent valve

Warning lights for Collision Mitigation System, Road Departure Mitigation, Adaptive Cruise Control. Lane Keeping Assistance, Auto High Beam. Features are now disabled causing safety issue. Dealer confirms issues and recommends repairs that have not not been solved by others online. Errors appeared before battery Failure in March 2026. Battery was replaced. Common complaint by many online. Need recall to fix.

I was merging into traffic on interstate. The car lagged as if it wasn't getting gas. I pulled over to get out of traffic. Scary situation. Please advise!

Hello, My 2018 Acura MDX has moisture and water inside the inner tailgate (trunk) tail light assembly, which caused the light to stop working. I understand there is a recall affecting some 2014–2020 Acura MDX vehicles related to moisture entering the tailgate light assembly, and my vehicle appears to have the same issue. Recall link: [XXX] Last week I visited the Acura dealership(Acura Columbus) in Dublin, OH for a fuel pump recall service. During that visit, the technician also noticed the water inside the inner tail light but quoted about $750 for the repair. Although my VIN does not show this recall, my vehicle is experiencing the same problem described. Could you please review and advise if this may qualify for recall coverage or goodwill assistance? Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
