I was driving down the highway today at 70 mph and all the lights illuminated on my MDX. It began to struggle to keep speed and eventually shut down once I was on the service road. I was extremely scared and nervous that I was going to be involved in an accident or the car was going to blow up as it started bouncing up and down while I was still on the highway.

I have three recalls on my vehicle. I am trying to get them serviced and the Acura dealership is stating that they do not know when they can service the fuel pump because they haven't created/issued any parts. They will not let me book to service/fix the connector rod bearing before August. I am concerned with the safety of my vehicle due to these recalls and not being able to get them fixed ASAP.

After driving for an extended timeframe (approximately 3 hours, trip was traveling between Des Moines, Iowa and Kansas City, Missouri) at Highway/interstate speeds, upon slowing down from those speeds, the vehicle goes into limp mode and check engine light begins blinking. After pulling over and turning car off and on again, normal behavior resumes. This has happened both as I arrived in the Kansas City area, and upon my return home to the Des Moines area. Depending on circumstances for when vehicle enters limp mode, there’s a significant risk of causing an accident. Dealer was unable to pull any codes and therefore is unwilling/unable to address the issue.

In March, I made an appointment at Lehigh Valley Acura in Emmaus, PA 18049, to address NHTSA Recall Number 23V-751 on my 2019 Acura MDX. When I got to the appointment on [XXX], the service technician told me that American Honda will only send parts for recall-related repairs for cases where the "vehicle is showing evidence of the connecting rod bearing defect." Since the evidence of the defect is that the car could "stall while driving," I believe this sounds like a defect that should be addressed immediately. I called American Honda on [XXX], and was told that they don't have sufficient parts to fix all the vehicles covered by the recall. The person I spoke to said that we would get a letter in the mail when it is our turn. I believe this is negligence on the part of American Honda and Lehigh Valley Acura. How do I get this defect addressed immediately? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2 Issues: Transmission shifts hard between 35-50mph and 50-60mph. Dealership accused me of utilizing improper gas which is not factual; this car has only received the recommended premium octane gas since I purchased it as a Certified Pre-Owned vehicle. Recall: vehicle is currently under crank shaft recall. In the original notification, Acura stated parts would be available in April. Per the Acura dealer, Acura told them parts will not be available until October. This timeline is unacceptable for such a serious safety recall (risk of fire/crash). I feel unsafe driving this car and am worried I will not get fair market value with the recall still open.

The contact owns a 2019 Acura MDX. The contact received notification of NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The contact stated while her nephew was driving at an undisclosed speed, he noticed smoke coming from the front and rear of the vehicle. No warning light was illuminated. The contact’s nephew pulled off the road to lift the hood of the vehicle where he saw flames. The Fire and Police Department arrived at the scene however, the fire had already been extinguished. The contact was unaware if a Police report was filed. There were no injuries. The vehicle was towed to the nephew’s residence where the Insurance Adjustor took pictures of the damages. The vehicle was towed to Mack's Automotive but due to the extensive damage, the vehicle was not repaired. The contact was informed by Mack's Automotive that the rod went through the engine causing the oil to leak which caused the engine to catch on fire. The vehicle was towed back to the nephew’s residence and remained unrepaired due to the cost and because the Insurance provider declined to pay to repair the vehicle because it was deemed a mechanical failure. The manufacturer was made aware of the failure and opened a claim; however, the contact had not spoken with the manufacturer personally. The failure mileage was unknown.
