2017 Acura MDX Engine

The contact owns a 2017 Acura MDX. The contact stated that while his wife was driving at an undisclosed speed, she heard an abnormal knocking sound coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the connecting rod bearing, resulting in damage to the engine. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling) but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 110,000.

All lights lit up on dashboard with no previous sounds, knocking, or issues. Upon getting the vehicle towed, the dealership said that the CAM Shaft and sensor needs to be replaced. Which is approximately a 4K dollar repair. Upon further inspection. The dealership showed me a copy of a 2018 notice where this was a known issue with a specific code of C0369 where it states that there should be no repairs but only replacment of the complete unit and that the machining of this part is know to have substandard machining spec issues which will cause the shaft to erode. This vehicle only has 67,589 miles on it. (which is out of warranty by 6800 miles.) All of the information that I have investigated states that the only way a CAM shaft goes bad is insufficient lubrication, improper break-in, reusing old/worn components, mechanical interferences, and inferior hardware/hardware not torqued to spec. I beleive this issue needs to be further investigated especially since there is also the new recall which states the crank shaft rod bearing was also failing due to the original machining was out of spec. In addidtion, if this was a known issue withthe CAM Shaft since 2018, why was I not notified and why is this not a recall? The dealership currently has 3 other cars in its service area with the same known issue. Of note, this vehicle was running fine when it was parked and upon starting the car and going approximately 5 mile per hour, all warning lights lit up and said to place the car in park. No other prior warnings or issues to speak of other than stalling when stopped at a red light.

While driving at freeway speed, fourth lane from the right, the vehicle became unresponsive to the gas pedal input and started to glide. I managed to get the vehicle to a narrow shoulder on the right before coming to a complete stop. I had one of my grand child in the car seat as a passenger at this time and I was very concerned about stalling in traffic and getting rear ended.

The contact owns a 2017 Acura MDX. The contact stated that on several occasions while driving at various speeds the vehicle lost power. The vehicle was taken to a dealer where it was diagnosed that the clutch and gear needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 40,000.

The auto engine disable function causes the car to stall unexpectedly. The car engine stops, and the car changes from Drive into Neutral. The only way to re-engage the engine is to place into Park and restart the car. Sometimes, it requires more than one attempt. Fortunately, this has only happened while the car has been stopped, but it has happened at several busy intersections, holding up traffic and creating a safety risk for me and others. Reading online, this is a known issue with suggestions to report this to NHTSA to include in the overall tracking. Hoping for a fix before someone crashes into my stalled car. I listed the last known date, but this happens with frequency (about 1x/week).

The vehicle stalls and loses all power when coming out of auto idle stop. This is a default feature that shuts the engine off when the vehicle stops to create fuel efficiency. But it is creating a terrible safety issue of having vehicles unexpectedly stopped on the roadway. The feature cannot be permanently turned off. Common issue on MDX forums without any real solution from dealership mechanics.

TL* THE CONTACT OWNS A 2017 ACURA MDX. THE CONTACT STATED THAT THE VEHICLE DID NOT START WHEN THE PUSH START BUTTON WAS DEPRESSED. AFTER 45 MINUTES, THE VEHICLE STARTED. THE CONTACT ALSO STATED THAT THE FAILURE OCCURED SPORADICALLY FOR APPROXIMATELY SIX MONTHS. THE VEHICLE WAS TAKEN TO ACURA OF THOUSAND OAKS (3945 AUTO MALL DR, THOUSAND OAKS, CA 91362) FOUR TIMES, BUT THEY WERE NOT ABLE TO REPLICATE THE FAILRE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 25,000.

YESTERDAY WHILE STOPPED A LIGHT, THE MDX REFUSED TO MOVE ONCE I TOOK MY FOOT OFF THE BREAK. THE ENGINE BECAME VERY LOUD AND 'EMISSIONS SYSTEM PROBLEM' AND 'BRAKE PARKING PROBLEM' APPEARED ON THE DASHBOARD. THE TRUNK OPENED BUT WDNT CLOSE AUTOMATICALLY. I HAD TO HAVE THE VEHICLE TOWED TO THE DEALER. THE VEHICLE HAD ISSUES STAYING IN NEUTRAL AND WOULD IMMEDIATELY REVERT BACK TO PARK. THE TOWING COMPANY HAD ME CONTINUOUSLY HOLD IT IN NEUTRAL IN ORDER TO GET IT ON THE FLAT BED. IT TOOK 45 MINS TO FINALLY GET THE VEHICLE ON THE BED. I WAS REALLY ANNOYED AS I'VE NEVER EXPERIENCED ANYTHING AS SUCH WITH MY PRIOR MDX AND WAS ON THE WAY TO MEET MY CHILDREN. WHEN WE ARRIVED AT THE DEALER, A TLX WAS TOWED AND HAD THE SAME ISSUES. THE VEHICLE SHUT DOWN AND WDNT MOVE LIKE MINE. THANK GOD I WAS NOT ON THE HIGHWAY. I HAVE COMPLAINED ABOUT THE SHIFTING OF GEARS WHEN DRIVING AND WAS TOLD IT WAS NORMAL AND THE VEHICLE WOULD EVENTUALLY CHANGE BUT IT'S ALSO STILL HAPPENING. NEEDLESS TO SAY I AM VERY DISSATISFIED AND DISAPPOINTED AND WILL NOT PURCHASE ANOTHER ACURA
