2021 ACURA TLX Complaints

I was traveling on the highway (on a very rainy day), when my car's green signal lights and orange engine light began blinking. Immediately, an orange warning sign on the dash read, "Some Driver Assist Systems Cannot Operate, Radar Obstructed". A few seconds after that occurred, I accelerated to pass a vehicle & as soon as I switched lanes to get over, my car went from speeds of about 85 MPH, abruptly down to 15-20 MPH. My safety was immediately put at risk as the driver I passed began tailgating me as if my actions were intentional. I attempted repeatedly to speed up, but my car just wouldn't go any faster. Once, I proceeded to get in the right line, I was almost hit by a group of tractor trailers. I called my spouse in a panic, who advised me to get off at the next exit. I followed his advice, pulled over, turned off my car & started it again. The lights turned off & proceeded to get back on the highway. About 3 minutes later, the orange light flashed the same message, "Some Driver Assists...." I immediately called Leith Acura & tried explaining what was occurring. Once hanging up with Leith, the dash continued to display "call ended" with Leith's number flashing every few seconds. The radio also turned off with a "No audio connection for FM Radio". Too afraid to accelerate, I drove minimal speed all the way to VA. Also afraid to drive back in the same condition, I contacted Crown Acura, who set an appointment for June 23, cancelling Leith. Service advisor [XXX] informed me that the technicians were unable to duplicate what occurred and placed me in a rental vehicle until my car was assessed and diagnosed. The next day I was informed my vehicle was ready and told the technology was reset. Before & after this, my phone calls are stuck in a limbo state where it will ring through Bluetooth, the number will display, but there is no way to pick up the call via phone or car display. "Brake" warning also blinks when there are no objects in front of me. *I have videos* INFORMATION REDACTED PURSUANT TO THE FREEDOM O

Hi there, My car has been to the Acura dealer multiple times for the same issue, and I'm hearing that alot of other Acura TLX owners are having the same issue. My car screen will randomly short, and can just shut off. Sometimes when I'm backing up, the screen will freeze and i wont realize that someone is walking behind the car, almost causing me to hit them. The audio system also can make weird crackling noises as well. There are definitely some safety features that shut off with the screen, though i cant pinpoint them exactly.

I currently have Kumho Ecsta PS91 tires on my 2021 Acura TLX that was purchased brand new and 3 out of 4 tires have cracks/splits all the way around the inside and outside sidewall. My vehicle currently has 30k miles and still has plenty of tread left on them as they are rated for 45k miles. Car has always had its routine maintenance done at Acura and tires are always checked and rotation is done also. Please look into this immediately ?? I was traveling on an Interstate at 70 mph and this could have been a tragedy for myself and others traveling. Also have pictures to show if needed

On two occasions the Collision Mitigation Braking System (CMBS) has improperly activated with HARD braking leaving me fighting for control. On one occasion, I was driving at 35 MPH on a divided boulevard in my home subdivision with no vehicles in sight. The second occasion occurred on the Florida Turnpike at 75 MPH while in the outside lane. There was no vehicle in front of me or to the side at that time. That was a scary moment. I want to emphasize that the CMBS employed HARD braking along with the flashing dash warning. After each instance I took the vehicle to an Acura dealer. First to Fountain Acura in Orlando who could find no DTC codes and blew me off by telling me it was my E-Pass transponder and window tint that caused the problem. That was utter nonsense. The second time I took the vehicle to AutoNation Acura North Orlando where I had purchased the vehicle as Certified Pre-owned (CPO) in April of 2022. They took my concern seriously, provided a loaner and kept the vehicle for four days. They also were unable to duplicate the issue and could find no DTC codes. They called Honda’s “tech line” and told me that same nonsense about tint and transponders. This “washing of hands” rather than taking ownership of this life-threatening problem made me start looking for others with the same issue. No surprise, I found 103 other Acura 2021 TLXs as well as RDXs and Honda models with NHTSA complaints for the same exact experience I had. Is AHM’s “tech line” telling all owners it is their fault for the improper activation of the CMBS? It seems to me that a change in the CMBS triggering algorithm needs to be made otherwise the more vehicles with the defective algorithm the more crashes will occur. This improper activation seems unique to 2021 vehicles. NHTSA records currently show no similar complaints for 2020, 2022, or 2023 model year vehicles.

The infotainment system glitches or goes static after a bump of any sort. Sometimes it would restart entirely. Or just not work until I stop and restart the car.

My wife and I were on the first day of vacation, driving from Virginia to FL by way of SC. Around 1pm I was driving the car on interstate 20 West in South Carolina near Bishopville. There were no cars in my lane in front of me and the car suddenly activated what Acura refers to as the CMBS system. The purpose of this is to stop us if it thinks we are going to run into another vehicle. I'm not 100% sure but I think this is related to the adaptive cruise control. We had not used cruise control that day because traffic on rt 95 South was extremely heavy. We had finally turned off on Rt 20 and traffic wasn't as heavy so we felt we could safely use the cruise control. We were traveling at about 73 mph and the car suddenly started hard braking. It was flashing BRAKE in big letters in the dash. There was another vehicle behind so I kept pushing on the gas pedal to keep going but the car literally would not release the brakes. The vehicle from behind hit us. There is a video cam in my car so I have a video that shows the car traveling smoothly then all at once bouncing and jerking as it keeps applying the brakes. We also have photos of the front of the car showing that the cameras that this system uses were clear and unobstructed. The other driver was charged but it was absolutely the fault of the Acura for this malfunction. Acura Roadside Assistance tried to tell us how to disable this system but the info they provided was for another year model and didn't work. We went on YouTube and found the correct information and have disabled this system. There were other videos on YouTube describing this exact issue with this system failure with Acura vehicles. We have also filed a report with Acura Customer Care. It is case #[XXX]. We have also reported this to our insurance company (Travelers) and to State Farm, the company that is handling the claim for repair. The State Farm Claim # is [XXX].

Noticed my 2021 Acura TLX A-SPEC SH-AWD has fluid leaking from the rear differential where the driveshaft connects. The vehicle has 16,531 miles on the odometer. Honda is releasing a recall for leaking rear differential on the Honda CRV as well Accords. Honda may want to include the Acura TLX's as well in the recall as they are reporting the drivesshaft may cause serious damage at high speeds if the differential is leaking.

Rotors warped and changed through warranty but loud humming and vibration is back after 2,000 miles on new rotors. Steering column is leaking fluid down to brake pedal. Steering wheel is making a clicking noise when turning. Speakers are crackling after Fakra replacement under acceleration or going over bumps.

While traveling on a narrow road and a narrow bridge, the lane departure system caused the car to veer left into another car. The road had no dividing lane marker. The car was totaled and my wife injured

WHEN BRAKES ARE DEPRESSED, THERE IS A SPRING RELEASE/CLICKING NOISE. AS WE HAVE PUT MILAGE ON CAR IT HAS GOTTEN PROGRESSIVELY LOUDER.
