Equipment problem #1

On or about October 21–22, 2025, I brought my 2020 Acura Tlx (brown, 99,000 miles, VIN [xxx] ) to goodson Acura of dallas for a recall repair related to engine concerns. The vehicle was returned to me on October 24, 2025. Shortly afterward, the car began to lag and hesitate while accelerating. On November 3, 2025, while driving to a doctor’s appointment on the bypass bridge in morning traffic, the vehicle suddenly stalled and lost power completely. This created a dangerous situation in active traffic. I recently underwent surgery following a serious burn injury, so limited mobility made this stall especially hazardous. After restarting the engine, multiple adas and system-fault warnings appeared. I contacted goodson Acura and was advised to bring the vehicle in. Upon arrival, the service advisor confirmed the warning lights but required a $205 diagnostic fee despite the recall work. Acura client relations opened case no. Xxx and advised the charge should not apply if related to the recall. After waiting several hours, I was told the battery had died and that front camera/adas systems were returning codes. This stall occurred less than two weeks after recall repair and could easily have caused a serious crash or injury. I am requesting a full investigation into the recall repair, the stalling issue, and any related safety defects. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

Equipment problem #2

Recall still listed as unrepaired after completion dear NHTSA, I am reaching out regarding an outstanding recall listed for my vehicle, even though the repair has already been completed. I took my car to an authorized dealership to have the recall service performed, and the repair was completed. However, the recall still appears as *unrepaired* in the NHTSA system. Because of this, I am currently unable to obtain a vehicle safety systems check certificate, which is required for \[registration/inspection/other—insert if applicable]. Could you please assist me in updating the recall status or advise me on how to resolve this issue? I can provide documentation from the dealership confirming the recall service was completed, if needed. The VIN# for my car [xxx] thank you for your assistance. Sincerely, vtek motorsports [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Equipment problem #3

I've received the recall notice for my car about 2 years ago. I've tried to schedule time with the dealership to get it fixed but they just keep telling me they don't have the parts or I have to wait till something "bad" happens first for them to prioritize me. This seems really unsafe and bad practice. I've reached out to Honda and they have open a case to review this but has not gotten back to me since. The car has stall once and a few times during the engine shut off while stopping, it takes a moment for the engine to come back, not normally like when I got the car. There has been a few time that there were cracking noise while I was driving. I stop driving the car as much as I can to avoid an accident happening. Please help me get some resolution with Honda, it's been almost 2 years.

Equipment problem #4

My wife and I had just turned into kroger's parking lot and I was looking for a parking space, we were probably going 15~20 mph. The car suddenly accelerated on its own. I was able to put on the brakes and slow the car down before we hit a pedestrian and/or other cars in the parking lot. We were fortunate that we were on an open stretch of parking lot, this may have turned out really bad. We drove around town after this happened and stopped and restarted the car several times. It has not happened again today.

Equipment problem #6

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 <mbrooks@metrowestacura. Com> sent: Wednesday, July 26, 2023 4:05:38 pm smelson, david <david. Smelson@umassmed. Edu> 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.

Equipment problem #7

My car has started to jerk. I called the dealership where I got it from and they told me that if it didn't jerk in there possession there is nothing they could do. It's a 2020 and it has a little over 28k miles on it. There are 2 open recalls on my vehicle, but my specific VIN isn't affected. I don't know what else to do .
