My car alarm keeps going off. It happened last week overnight 3 times (12:30, 1:30, 2:30) last week and a week later again overnight.

I am concerned because the 2018 TLX Acura I purchased is having stalling and starting issues. When I first purchased the car and it had fewer than 17,000 miles problems appeared with the lights coming on, parking break and emission issues. It had to be repaired 3 times. The recalled Fuel system/fuel pump (recall # 19v060000) was replaced in Feb. 2020, which I hoped fixed any mysterious stalling. The first time it stalled I was in a COVID parade at work to support the community. It started up and I did not think about it again. That was in the spring of 2020. Again on Thurs., July 8,2021 the battery light came on and the car stalled while I went to push the gas peddle to go at a light that turned green (It occurred twice in one day). Instead the car stalled. I went to restart, first it said stuck in gear, then it was fine. The dealer claims it is because the gear selector switch had crumbs and too much dirt in it. I find it strange that Acura left such a vulnerable part exposed to elements with cup holders next to it and in a society that has a drive-thru for almost any food. Approximately one week before I got the same messages when pulling into a parking spot just before stopping. I restarted the car and it was fine. Also on May 24, 2021 my car, which had 71,657 miles had another issue with the Green key light flashing and the car did not start. The dealer replaced the control unit for keyless entry. It first appeared when my brother couldn't start my car. He told me and I went to start the car and it was fine. He was not familiar with my car and I thought maybe he didn't hold the brake to start it. Not long after I went to leave for work in the morning and the car did not start at all. I saw the blinking key. my car was towed to the dealer and repaired it. I have never had a car with this type of repeated problem of stalling and not starting. It may be different parts, but are they band aids for something bigger?

I bought this car on October 7, 2017 and by December 22,2017 (dealer report attached), I had already experienced and reported for the first time the malfunctioning infotainment system on my 2018 Acura Tlx. This issue is ongoing. The technological flaw (pictures attached) is that the infotainment screen will freeze during operation of the vehicle. This impacts several essential safety and driving capabilities. When the screen is frozen, the backup camera fails to display as the frozen screen will not unfreeze until the car is turned off and back on. This means that you have to park on the side of the road to reset the system. This freeze also causes your programmed gps route (on-screen and voice directions) to go haywire and completely fail, again requiring you to leave the road and find a place to park, turn off the car and turn it back on. On several occasions, I have been on family road trips and the infotainment has frozen and I have had to leave the highway and reset the system. This is dangerous for me and others given the terrain is unknown and driving (especially at night) carries a lot of risk. I have attempted to address this issue numerous times with five dealers in the san francisco bay area. None of them have taken accountability nor acknowledged my problem, saying they cannot replicate it. However, I have noticed the infotainment freezings tend to occur on relatively longer drives. This infotainment defect is not unique, there are several complaints and ongoing lawsuits regarding the infotainment systems in Acura Tlx and rdx of various years (2019-2020), but my model's year has not been addressed. My family and I do not feel safe in this car. I bought it when it just came out and it has been a disappointment, compounded by the low-quality customer service that has consistently ignored me for the past 2+ years because they claim they cannot replicate it.

This will be the 12th time where my car comes to a sudden and violent stop for no apparent reason - due to the collision mitigation breaking system activating with no cars in front of me. The last time this happened, a few weeks ago, there was someone behind me and it was a very close call. There was also a passenger who didn't know what hit him. I have brought the car in for service only to be told everything was fine. I attempted to bring it in for service again and I was given the run around that they had no availability for weeks. I have email correspondence with Acura customer care and anyone involved in the purchase of this vehicle, including two separate dealerships and I have received a generic response with no solution offered. This is a dangerous system that is clearly not tested appropriately and I will be keeping it turned off just as long as I can remember to do so. These incidents vary - most times it occurred on a local street. It happened twice on an interstate highway as I was entering going about 45mph. All times this has happened I was traveling over approx 35mph

On 6/25/19 at 16:39 I was driving my 2018 Acura Tlx northbound on a four lane city street at approximately 35 mph. Road conditions were dry and clear. As I approached the intersection, the cmbs (collision mitigation braking system) beeped and brought the vehicle to a complete stop despite there being no car ahead. This surprised me and nearly caused an accident as the truck behind me had to stop suddenly. While braking the vehicle ignored all throttle input, thus my engine raced and spun the front tires once throttle input was restored. The event, with sound, was captured via my dashcam, I have attached a still image from the dashcam video and can supply the footage if needed. My Acura is due for service next month and I plan to report this issue to my Acura dealer at this time. I changed the vehicle 'forward collision warning distance' setting from 'long' (default) to 'short' and have not had the same issue recur.

2018 Acura Tlx unexpectedly and for unknow reasons initiates an emergency (sos) call, one of which resulted in a 911 call to nys police. This has happened almost half a dozen times. We didn't keep track at first but now know to do that. Most times this happens while the car is moving. Nothing unusual about the car or the weather or anything we can think of that would initiate this. The car has not reported that anything is wrong. On one occasion the car called sos and when Acura person didn't get a reply from the car they called 911. NY state troopers responded. The car was stationary in our driveway and had been for 12 hours. One of the troopers fell on ice covered lawn trying to get to the front door. I have asked Acura for the call logs so I can provide to the dealer with the exact date and time of these calls. 16 days after my written request I still have no logs. When this happens, it is a very scary experience. The two displays indicate sos in large red letters and the map lights up with the cars current location in 10 digit coordinates. Then someone comes over the speaker to ask if we are okay. This would be reassuring if we were in the ditch on the side of the road or incapacitated but going to the grocery store and it is going off has scared my wife at least three times. This has happened to me when I was driving too. Acura client relations has been zero help in getting the logs of times. Additionally, I think there is a systemic problem because Acura placed the concierge and the sos buttons very close to the garage door opener and overhead lights. We have, on two of three occasions pressed the button by mistake. On all those cases we told the person calling we made a mistake. All other times (which we don't know because Acura hasn't given them to us yet) the car initiated the call all on its own.
