2025 Acura TLX

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

I was driving in heavy traffic when the steering on my 2025 Acura TLX AWD froze up. Several codes were displayed. I managed to direct the vehicle to the right shoulder where I turned the engine off. I restarted the engine but the steering was still inoperable and the codes were still displayed. I turned the engine off again. When I restarted it the second time the codes were gone and I was able to drive the car back home.

Description of Safety Defect: While starting car up, the digital instrument cluster (speedometer and all primary driver instrumentation) goes completely black with no warning. The infotainment system continues to operate normally. After driving a short distance (sometimes only a few miles), the vehicle then experiences a complete loss of power steering, making the car extremely difficult or impossible to control. This creates an immediate risk of a crash, especially at speed or during turning. In multiple instances, after this failure occurs, the vehicle also becomes difficult to shut off, remaining in accessory or powered states despite attempts to turn the vehicle off. This defect involves simultaneous failure of: •Driver instrumentation display •Electric power steering assistance •Normal ignition shutdown behavior The loss of steering assist results in a sudden and unexpected loss of vehicle control. This appears to be an electronic or control-module failure affecting multiple safety-critical systems. Safety Impact: This defect poses a serious risk of crash, injury, or death due to sudden loss of steering assistance and lack of speed/vehicle status information while driving. Frequency: Has occurred twice - each time requiring roadside assistance to get the car to the dealer Warning Lights or Messages: None - just complete loss of instrumentation cluster Dealer Response (if applicable): Dealer initially claimed it had fixed, but it occurred again within 24 hours of retrieving from dealer. Dealer has now had car go over a week claiming that it needs to generate the fault state more than once before it will make any warranty repairs

We have three Acura vehicles at home and this is the newest one - 2025 TLX A-Spec. The vehicle is only a few months old and already suffered two INFORTAINMENT Screen failures. This is the primary screen on the dash that shows navigation and other information. The screen goes dark completely due to either an electronics/hardware issue or a software issue. This could be a safety issue if the driver is driving using the map app at a busy intersection, and the screen stops working. Once it is out of order, the only way to fix it is taking it back to dealer and do a battery level re-set. Not acceptable! Please investigate and start a recall if needed. Thanks so much for your time.

While driving in humid, rainy conditions for over five hours, I experienced a sudden and dangerous loss of acceleration. Moisture appears to have built up, resulting in a misfire and a flashing MIL/Check Engine light. This occurred while I was overtaking another vehicle just before entering a restricted-width construction zone, making the situation extremely hazardous. The complete loss of acceleration lasted for about a minute. Afterward, I was only able to maintain minimal speed by flooring the accelerator. I continued in this limited-power mode until I could safely exit the highway. After shutting off the vehicle for 10 minutes, I restarted it, and it operated normally. After researching this issue, I found active recalls and service bulletins describing this exact behavior, including: NHTSA Recall Number: 25V-031 Acura Campaign Number: EL1 Service Bulletin Number: 25-010 Additionally, an earlier bulletin describes identical symptoms: Service Bulletin Number: 20-053 (Version 4, dated March 12, 2024) Despite these matches, my VIN does not show any active recalls or bulletins. When I brought the car into the dealership to address this issue under the bulletin, they informed me they could not perform any service since my VIN was not listed. Given the severity of what occurred, I am requesting urgent assistance in updating or reviewing the recall eligibility for my vehicle. I would like to prevent this issue from recurring, especially in dangerous conditions. Thank you for your attention, and I look forward to your prompt response.
