I purchased a new Acura TLX in 2020. The following year it took it into get state inspected in Massachusetts. My care failed for emission 3 times. I brought it back to the dealer (herb Connolly) in Framingham Massachusetts. They kept it for 3 weeks, worked on it and Tod me it was all set. The following year I brought it in for a state inspection. The same thing happened. They told me that they had seen a few of these cases. They found a way to get them to pass. They have to drive it at different speeds for a few hundred miles. I asked that they fix in properly and they noted that they did not have a fix. This was all after I picked it up. I told them I was concerned as I worried this could keep happening. They encouraged me to call Honda Motor Corp. I spoke to them several times and they denied the problem. I am not in my third year. Car is still under warranty and it again failed inspection. Below is an email from the service manager on how to get it to pass. From: Michael Brooks Sent: Wednesday, July 26, 2023 4:05:38 PM To: Smelson, David Subject: Passing Inspection Hi David, As discussed we have not received any updated procedures or available software updates to get these cars to store the memory for the readiness flags. This is an issue what we have had to drive the car in very specific patterns to get it to pass. The main thing we do is DO NOT SHUT THE CAR OFF AFTER DRIVING IT JUST PULL IT INTO THE INSPECTION BAY AND LEAVE IT RUNNING DURING THE INSPECTION. There are a few flags that are notoriously tricky to get to flip. Usually we use our $20 -??obd-?? tool that we got off amazon which monitors the flags in real time so we know when it is ready for inspection. Below are the driving patterns we follow to get the problem flags to turn over: O2 sensor This is one of the trickiest ones, we seem to have the most luck getting this one from continued driving so there is not a spec

Software update completed June 2022 When coming to a stop light, my car shutdown. Went into neutral and took about five seconds to restart. It happened the following day and I was rear ended. No injuries occurred.

After coming to a stop at a red light, the vehicle engine turned off as designed with auto start stop. When the light turned green, the vehicle temporarily restarted when I released the brake pedal, but immediately stalled and would not restart. This is a major safety concern as I was on a four lane road with traffic all around and I was unable to move. I had place the vehicle into park, turn off the ignition fully, and attempt to restart the car. It eventually restarted, but it took nearly 90 seconds. This is a danger to myself, and to the traffic around me as I was fully stopped on a road with 40 MPH limits and a lot of traffic.

Two times in three weeks with the auto idle stop active the car failed to restart on a green light. Following all the prompts in the car it takes over a minute to re start the car while blocking traffic.

I was driving around 30miles/hr and the engines shut off unexpectedly. I was stuck in the middle of a highway and the engine didn-€™t turn back on. The dashboard showed total failure. The car was one year old with 11k miles. I just had it serviced by the dealer.
