“My 2017 Acura MDX had a complete engine failure because of know critical rod bearing issue which hasn’t been extended to all 2017 models of the MDX. My engine completely failed when I was entering a roundabout and nearly caused the car behind me to rear end me then left me dangerously stranded in the roundabout. Even though this is a known issue for this year, make and model of my vehicle Acura said it was my fault without asking for detailed maintenance records and said this recall only applies to certain vehicles produced. I had to pay $7995.71 for a new engine and this issue needs to be addressed before someone is killed. Thank you”

“A rod bearing inside the engine failed and created metal shavings inside the engine. The vehicle has not been fixed yet, so it is available for inspection currently, but I will be having the engine replaced in the next 2 weeks. With the metal shavings inside the engine it could cause a catastrophic failure of the engine while driving at any point The dealer has inspected and diagnose it as a rod bearing failure I reached out to Acura customer service to make them aware and ask for assistance in reviewing for coverage in the ongoing recall, but since my vehicle was not manufactured in the plant covered under the recall, they are unable to help. I asked for a good will credit and after they conferred with the dealer they stated the failure was not due to a manufacturing defect, therefore they cannot help. There were no warning lamps or messages from the vehicle. The only symptom was a ticking sound, that got louder at higher RPMs, coming from the front of the engine on the passenger side. I’ll also add that based on CARFAX report and our service records since we bought the vehicle, all recommended maintenance has been performed as recommended by the manufacturer.”

“My vehicles motor is internally destroying itself. The rod bearing has gone and the motor is none functional. The car only has 98k miles. I have gotten the oil changed every 3k-4k miles and used 0W-20 oil as the manufacturer desired. It seems as though there has been 1.4million cars with this same issue as mine. I think a recall is in order. OEM new motor is $25.7k.”
