| Jul 2024 | UNKNOWN OR OTHER | This vehicle engine has shut down in traffic on 6 separate occasions over the course of a year. Each time, the car locked up and would not restart until 1-3 minutes passed. This happened in stop and go traffic on the interstate. The other instances were at stoplights. I believe this is an issue with the auto idle stop feature. The dealership is unable to recreate the issue, thus no resolution was offering during the warranty period. | Crash: No Fire: No | Unknown |
| Jul 2024 | UNKNOWN OR OTHER,ENGINE | No warning lights or other indications occurred. This is the 2nd time while sitting at a stop light that the car has gone into neutral gear and it was unknown until the traffic signal turned green and I could not go. I could not shift into drive. The remedy required that I shut the car off and restarted (very little time between) before putting it in gear. Both occurrences were with idle stop function on. There is an entire discussion forum on this exact issue on [XXX] . Being first in line at a stop with 4 other passengers and a line of drivers expecting me to go on green is a sure way to result in an accident. The car goes in for regular service next week and I will bring it to the dealer’s attention.

| Jul 2024 | UNKNOWN OR OTHER,ENGINE | The car's Auto Start/Stop (AST) function is malfunctioning. It frequently fails to restart the engine after stopping, causing the engine to completely shut down at traffic signals. When this occurs, the car must be shifted to park and the engine manually restarted. | Crash: No Fire: No | Unknown |
| Jul 2024 | SEAT BELTS | 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. | Crash: Yes Fire: No Towed | Unknown |

| Jun 2024 | ENGINE | Persistent Idle Start issue not being addressed by the Acura dealership despite multiple trips to the dealership with the same issue. My SUV intermittently shuts down in the middle of busy intersections leaving me at great risk for a crash and bodily harm. There is a Service Bulletin issued in January 2023 by Acura admitting to the issue and it shows how Acura will resolve the issue for affected vehicles. Unfortunately Acura is not following their own Service Bulletin, and a recall of these vehicles needs to be issued to address the affected vehicles. I am requesting the NHTSA to take immediate action and issue a recall for this known idle start issue that is putting many Acura drivers at increased risk for bodily harm. | Crash: No Fire: No | Unknown |

| May 2024 | UNKNOWN OR OTHER,ENGINE,FORWARD COLLISION AVOIDANCE | I purchased this car in September of 2023 with 23,000 miles on it then I received a recall in December 2023. I purchased tires for my car at the dealership and they scheduled my car to have this recall to be fixed on Monday May 13, 2024. I brought the car in on Monday and received a call on Saturday May 18, 2024 to pick my car up from the dealership that it was fixed. I took my car to get gas and two lights on my dash board came up one about my emergency brakes and the other code stated that there is a engine problem and immediately bring the car to the dealership less than one hour of picking it up from a so called recall repair that I was told was going to take two weeks to fix ended up less than 5 days and the car is back at the dealership less than a hour of picking the car up today. I am pissed off and the car is a $40,000 car I paid for with these types of problems when Iam paying a $680 a month on the car note and can’t drive it . BTWay the car smelled of burnt oil while driving it back to the dealership when the lights came on. I want my money back on this recall I need to let you know that is why I bought a new car so I wouldn’t have to deal with this big ass migraine.
