2018 Acura TLX Complaints

  • Steering, suspension 01/12/2026

    While performing routine maintenance on my 2018 Acura TLX, I discovered a critical structural failure in the front right (passenger side) lower control arm. The factory weld connecting the stamped steel control arm to the compliance bushing housing has failed and separated. Visual inspection reveals a clear manufacturing defect: there is a significant crater and void in the weld bead, indicative of incomplete fusion or a "start/stop" error during the manufacturing process. This is a latent structural defect, not a stress fracture from mileage or impact. The weld has begun to separate from the housing, leaving a visible gap. Safety Risk: This failure compromises the suspension geometry and structural integrity of the vehicle. If the weld completes its separation while driving, it would result in the control arm detaching from the subframe, leading to immediate loss of steering control, wheel collapse, and a high probability of a collision. Status: No warning lights were illuminated prio...

  • Engine 10/20/2021

    The engine has been making rattling noises when you start the vehicle from a long rest, mostly over night, since it has about 24k miles on it, when I purchased it used. I noticed it some time after I purchased it. Took it to Honda dealer in Hickory, NC, but they couldn't hear it. Later also took it to Acura dealer in Charlotte, NC. They couldn't hear it either. I recorded the sound and played it back to them.

  • Engine And Engine Cooling 01/31/2021

    The contact owns a 2018 Acura TLX. The contact received notification of NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The contact stated that while driving on several occasions at various speeds and while the vehicle was idling, there was a valve tap coming from the engine compartment, and the vehicle failed to restart. The vehicle was towed to a dealer, where it was diagnosed, and determined that a rod had pushed through the wall of the engine, and the engine needed to be replaced. The vehicle was repaired, but the failure reoccurred three years later. The manufacturer was notified of the failure. The failure mileage was unknown.

  • Electrical System 10/23/2025

    Odometer Fraud. The contact purchased a 2018 Acura TLX. The contact stated that it was discovered that there was a mileage discrepancy. The vehicle was purchased on September 10th, 2025, as a dealer sale. At the time of purchase, the vehicle mileage was 76,410. At the time of registration, when the title was received, it was discovered that the mileage was 176,410. The title read, "Not Actual Mileage, Mileage Tampering," which indicated odometer fraud had been detected. After ordering the Carfax Report, the report indicated that the mileage 176,000 miles at the time of purchase. The contact had not reported the odometer fraud to any other parties.

  • Forward Collision Avoidance, lane Departure 09/28/2025

    I got 5 lights on my dash stating that I have an auto high beam problem, road departure mitigation system problem, collision mitigation system problem, lane keeping assist problem, and adaptive cruise control problem. I got these lights on my dash at the exact same time and this happened 1 week after my car alarm started going off randomly. I will now have to change my windshield camera sensor. Seems like this is an issue with many Acura owners.
