2018 Acura TLX owner complaints

The car failed to turn back on after the auto stop fuction turned the engine off. This left me stranded at a green light. After a few seconds the car put itself in neutral and I slowly coasted to the side of the road as I was on a hill. It would not start for around 30 seconds, remained in accessory mode with the engine off. Finally it started and I cautiously drove home. The oil and coolant levels are still perfect and I got the battery tested. Not sure why it would not start back up.

Vehicle is having problems w original recall issues. Car stopping on its own on the highway, car says it’s on E all the time but has gas, car hesitates continually and sometimes just stops, electrical system is having major glitches, transmission and engine having major issues with hesitation and delay. I’ve bright it back many times and I’m beyond frustrated with no resolution. It’s unsafe to drive. Problem since day 1 I got the car. I’m scared to drive it.

I've had multiple failures on this vehicle. First, the engine had a rod knock and Acura gave me a very hard time approving the repair and eventually replacement of the engine. Second, the ADAS system is not working and is a huge safety concern. I keep getting error messages that my road mitigation and lane keeping assist systems do not work. Third, the ABS module system cannot communicate with my ECU and is not working properly. Another safety concern as this controls a lot of the wheel speed sensors, brakes, etc on this vehicle. A quick Google search for acura tlx ABS module repair will bring up pages and pages of people complaining about this very same problem yet Acura is not doing anything about it. This problem also affected other models such as the TSX, TL, RL, and the Oddysey. I've

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.

In September 2023 went in for an oil change. Next day all My CMBS, ACC, LKAS and Road Departure Mitigation System all light up on my dashboard as well brake system light. I called and took the car in they said that it had something to do with the camera sensor. I left a complaint and the manager called after I explained to him he said he would call me back. 1.5 years later he never called back. In October 2024 my car alarm started going off for no reason. I took it in and $1000 to fix. Seems like a lot of electric issues with this car

Hi, I’m having issues with my fuel pump / engine and I seen online there was a previous recall for this issues regarding my year make and model but when I search my vin it’s not included? Not sure why when I’m having issues related to that exact recall. I believe it can be related. I took it to Acura and they want to charge me 5,000 dollars for repair. I have a 2018 Acura tlx 3.5 v6 which is stated in this photo attached. Can I get some more clarification please? I’m having all issues notated on the photo. Regarding car idle, fuel issues, stalling and more. My car slid into Neutral while I was driving twice! Super scary. When I took it to Acura they diagnosed everything that was in the recall? Not sure why my vehicle isn’t included when it’s very obviously related

Nothing has happened. I just can’t get the Acura dealership in my area which is Jackson Mississippi Jackson Acura. They do not return calls at all and I would like to get my recall on my 2018 TLX repaired. I contacting them about 3 to 4 months ago. Just recently contacted them again for two weeks straight and no one is responding at all. I’m not sure what is going on with this dealership or the management but again I’ve left several messages for Chelsea,her supervisor and the manager of that store. The address: Acura of Jackson 800 Adcock St., Ridgeland, MS 39157 service phone number (844)362-6839

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.

Faulty high pressure fuel pump. Technician told me he sees a lot of these. If so, why isn't there a recall?

i took my car to acura carland in duluth georgia and i went initially for a check up on my recall i was notified for regarding my rod bearing and was told that there’s nothing they can do about it and offered to do a wheel alignment on my vehicle and that should help with the knocking noise i had coming from my engine and that i would have to wait till january for anything else regarding my recall. i asked what could i do until then and i was told to keep up with my oil change and that its until january. i even asked for a loaner and was denied stating that they don’t offer that which was hard to believe. a month after my recall on december 7th at 9:03 est pm my vehicle made more knocking noise way worse than before i had took it to acura carland and i was traveling home from work and sudd

The transmission have notice of vibration and rough shifting between 30 to 45 MPH.

Date of incident : August 31,2025 Around 9pm on August 31, I was fixing to accelerate at a green light. I pressed the gas pedal, my car went up to 40 mph and then the engine failed. This is due to a recall on the bearing rods for 2015-2020 Acura TLX. The incident occurred a month after financing the car. I don't have a warranty, so I opened up a case with the manufacturer to get help with the repair cost (which is 25,500 for a new engine block and 2 new cylinder heads). Unfortunately, Acura denied assistance. The car only has 68880 miles on it. The rod snapped and put a hole through my engine block. Shame on the manufacturer for denying assistance. I'm now stuck making payments on a car I cannot drive. Yes I have insurance, but it was not involved in an accident so I'm helpless there.
