2021 ACURA TLX Electrical System Problems

While using the Air Conditioner in Comfort Mode Suspension settings on my Advanced SHAWD model, the front suspension intermittently squeaks and creaks. It is very audible in the colder months or after it rains.

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.

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...

I am reporting a critical safety issue with my 2021 Acura TLX (VIN: [XXX] ), specifically related to the transmission and transfer case. The problem is centered around the transmission’s spline splitting into the transfer case, which causes severe jerking while driving. The car moves forward erratically, jumping up and down, and on multiple occasions, the vehicle has shut off while driving at highway speeds. This is extremely dangerous and poses a significant risk to my life and others on the road. This issue is widely reported by other Acura owners online, and it appears to be a common defect with the transmission, specifically the remanufactured transmission part number 06200-6T2-A02RM. The cost of repairing this issue exceeds $5,000, and since the vehicle is no longer under warranty, I am deeply concerned about having to replace both the transmission and transfer case, only for the same problem to recur. The vehicle...

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...

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.

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.

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.

The vehicle VIN - [XXX] The vehicle, 2021 Acura TLX, was purchased on June 8, 2021, from the showroom floor of Metro Acura Dealership. The vehicle was sold as being compatible with iPhone, Bluetooth HandsFree Link, and Apple CarPlay. Not to mention the innovative technology, Automatic Lighting Control, and Auto-Idle Stop System. The vehicle was purchased with a full 4 year/50,000-mile warranty. I have dealt with Metro Acura in Montclair, CA, Spreen Acura in Riverside, CA, and Wittmeier Honda in Chico, CA. I have attached the service reports from the said dealerships for your review. This does not include the three times I have called for roadside assistance due to being stranded by the 2021 Acura TLX. September 6- The vehicle would not unlock, even with the key. Stranded in a parking lot. Called Roadside assistance by the time some came, the car unlocked. September 8- the warning light Auto...

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.
