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.

If the car thinks the door is not fully closed, it will not allow the car to go into drive. My husband put the car into reverse and backed out onto a busy highway. He tried to put the car into drive and it would not go because the car's electrical system thought the door was not fully shut (it was). He had to shut the car off completely and open/close the door again. This put him in a very dangerous situation and he could have been killed by oncoming traffic.

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 was driving down the freeway, in a new 2021 Acura TLX with 2000 miles on it. It was raining when I went to switch lanes and floor it to pass another car and the check engine light came on and the power dies and speed dramatically slows down and I’m unable to accelerate. The check engine light is flashing and the car will not reach 40mph. Again I’m on the freeway. This was a very dangerous situation. There were no warnings leading up to this catastrophic fuel/engine issue. I took the car to the Acura dealer who said there had been reports of issues related to water getting into the car’s intercooler for the turbo causing the car to misfire and then going into “safe mode” with a flashing check engine light. They installed Acura SB 20-053 PGM-FI update. I’m picking the car up on 2/6/22 and hoping the issue is resolved. Again this was a serious fuel engine issue that if I’d been passing a car on a two lane road into oncoming traffic could have been deadly

How Acura Lost my Business The fact that no one from Acura will take responsibility for the ongoing issues has reaffirmed that my long-term commitment to owning Acura’s is over. Honda will only communicate via the phone and say "if the dealership can't fix it, neither can Honda." I decided, after months of difficulties with things not working correctly in my car, to trade it in. The last straw was when I looked up the Acura TLX Blue Book value; the car had a safety recall I knew nothing about from Acura. The passenger front seat airbag can deploy prematurely in an accident, and cause an injury. The professionals at the local Acura dealership cautioned me not to let passengers sit in the front seat; therefore the car was no longer usable for two people upfront. Acura can't fix the recall safety issue because there are no parts. This follows months of attempts to address other issues with the upgraded technology package not working correctly. Honda/Acura headquarters, and the Florida Attorney General, provide no written responses despite following the Lemon Law protocol. After owning my fifth Acura, a 2021 TLX, I recognized I could no longer count on the safety I’d come to expect. My daughter had come out of totaling my first Acura, a TSX, without even a bruise or scratch more than twenty years ago. This had secured my loyalty to the brand, I had thought for life.

In many instances while driving about 40-60 MPH and with no vehicles in front the car would suddenly brake.

6/5/2022

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].

SUSPENSION

I would like to report a serious safety issue with the 2021 Acura TLX Type s. Recently in April 2024, while driving, I heard a loud pop from the vehicle, and it turned out that the transfer case had burst into the transmission. This failure has rendered the rear-wheel drive non-functional, resulting in severe oversteer. This oversteer is especially dangerous because the vehicle is now operating as front-wheel drive, which creates an unpredictable and hazardous driving experience. This issue could lead to a catastrophic transmission failure, particularly at highway speeds, posing a severe safety risk to me and other drivers. I have contacted the dealer about the problem, but they have refused to take any corrective action. I’ve also found that multiple other owners have reported similar issues with this model, highlighting a potential widespread problem with the transfer case and transmission interface. Given the safety risks associated with this failure, I urge NHTSA to investigate this defect and take appropriate action to ensure public safety.

11/9/2024

The transfer case blows up and which causes the all-wheel-drive system of the car to go away and the car becomes from wheel drive which changes the way the car drives and makes it very dangerous. The car has a lot of oversteer and this is very dangerous to highway roads.

When Driving my vehicle I abruptly lost power steering on the freeway. I received an error on the screen " Electric Power Steering Problem, assisted steering reduced". I was able to safely drive my car off the freeway. However, I feel like this problem can cause someone else with not enough strength such as an elderly person to loose control of the vehicle if they encounter the same issue. I took my car to the Acura Dealer, and they advised they needed to replace the Rack and Pinon due to a " Steering Position Sensor" Issue.

Purchased new 2021 Acura TLX in April 2021 from Leith Acura Raleigh. On 5/22, 7/6, 7/23, & 11/2/21, the fuel capless unit was adjusted once replaced 3 times. American Honda is aware of the problems with the part & sent service bulletins to every Acura service dept. American Honda stated this & the 2 dealerships did also. On 8/4, there was an issue. Steering column began dripping grease. Grease dripping from steering shaft bolts "due to extreme heat". 12/7/21, extremely loud, high pitch squeal from brakes due to issue known by American Honda. Service bulletin sent to Acura service dept. Rotor rubs against another part on these cars. They explained there's no fix as of yet. What component or system failed or malfunctioned, & is it available for inspection upon request? Fuel capless unit (already replaced 3 times), steering column (steering shaft bolts), & brakes. Available for inspection whenever you all need for me to take it to the dealership again. How was your safety or the safety of others put at risk? American Honda has advised all Acura dealerships that these are known issues. They will not label them as recalls because they do not put Acura owners at risk, according to them. But, they send service bulletins to the dealerships advising all Acura service departments that they know about these problems. The steps to fix the issue may or may not work per dealers. As for the brakes, they've explained that they currently do not know the fix for the issue. They're still trying to figure it out, according to both Acura dealerships. Has the problem been reproduced or confirmed by a dealer or independent service center? Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes it has on at least 6 occasions by Acura dealerships. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, there have been warning indicators & messages.

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

On a slightly snowing evening driving on the highway, a warning was displayed indicating "Some Driver Assist Systems Cannot Operate, Radar Obstructed" and the green icon turned orange. Traveling about 45 mph, I slowed down to get over and the car drastically slowed down without me pressing the brake. After about 10 more minutes of driving the icon turned green again. This has happened on more than one occasion creating a serious safety risk, typically during inclement weather.

While I was driving on the highway I heard a loud pop over head and when I open my roof shade I saw the my sunroof was shattered. Then glasses started flying everywhere. The shattered pieces of sunroof glasses put me at risk and other motor vehicles on the road. I looked up online and found out that this is an ongoing issue with Acura/Honda sunroof exploding. Acura hasn't made a recall yet.

The wipers come on by themselves and do not turn off. The engine may or may not start with the key fob nearby. All the dash warning lights come on with warnings about the brake system, the transmission, the steering, the adaptive cruise control all reporting a problem. The vehicle goes to limp mode and throttle response is severely reduced. There is some sort of water leak which is shorting out or causing the BCM or body control module to act erratically due to water from rain getting into the area because of improper weather sealant placed during manufacturing. There is a service bulletin that was put out in roughly April of 2024 that describes this issue affecting the 2021 TLX models.
