The fuel delivery system, specifically the fuel pump, has malfunctioned. This vehicle is subject to a fuel pump safety recall, which was reportedly repaired in 2022; however, the vehicle continues to experience the same failure symptoms and is available for inspection upon request. The vehicle has stalled multiple times at highway speeds, resulting in sudden loss of power while driving and creating an immediate risk of collision with surrounding traffic. My family was in the vehicle during these incidents, significantly increasing the risk of serious injury or death. The problem has been reproduced multiple times, including after the vehicle was taken to an authorized Acura dealership. During the most recent visit, diagnostic trouble codes were cleared, but the recalled fuel pump was not repaired or replaced. After being released by the dealership, the vehicle stalled again under similar driving conditions. The vehicle was inspected by the dealership, but no corrective repair was performed beyond clearing codes. The manufacturer has not yet properly remedied the recurring safety defect. Prior to stalling, the vehicle exhibited intermittent hesitation, loss of power, and engine shutdown. Warning indicators and fault codes were present at times and were cleared by the dealership without resolving the underlying issue. These symptoms have continued intermittently since the recall repair. This appears to be a failure to properly diagnose and correct a known safety defect, resulting in repeated dangerous highway stalls and placing occupants at serious risk.

For some time now, before I was aware of this service, my car warning lights indicate that there is an issue with my forward collision, my lane departure, and the lane keeping assistance. It further indiscretion to clean my front windshield. I do so, but the warning still remains. Then some time will pass and the warning goes off. This warning happens sporadically, even giving impression of some hesitation while accelerating, and other times with drag when breaking. I made mention ofv this concern once to my dealership, but they said because it was now out of warranty, the check for the problem world cost $200. But now after reading of similar issues with other cars on this site, I will pursue a check on it.

This vehicle is so unsafe . I had lots of different situations happen and when I take it to the dealership they check it and say it's fine ! The vehicle stalls and hesitates and I get sensors going off constantly including the brake sensor when there is nothing in front of me for it to go off . I've had the vehicle go in park by itself while on a light. The vehicle doesn't start and always needs a jump I got the battery checked multiple times and the dealership told me my battery is good and I have to charge it . I believe there is an electrical issue with this vehicle . My vehicle only has 30,000 miles I have all my maintenance done at the dealership on time I purchased this vehicle thinking it's reliable being I'm a mother of two kids!

The car nearly stalls, rolled back 3-4 feet prior to restarting after the idle stop had in- gauged. The transmission shifts from 1-4 like someone who never drove with a clutch, even though it is an automatic. It hesitates and nearly stalls when doing slow maneuvering in and around parking lots and slow traffic. I have nearly had accidents due to the hesitation in traffic. When using cruise control out on the expressway, the car will not maintain its set speed on a downhill grade, it gets jerky and increases speed as much as 10-12 MPH unless I ride the brake. I have had it back to the dealer twice now, the first time they did all the updates on the computer and fuel pump...its just as bad if not worse. The car is not safe and should have a complete recall!!! The next questions ask for a specific time and date...this is ongoing and has been happening since I purchased the car in january.

I have been to the dealer 2 times for transmission problems. The car has poor acceleration and hesitates shifting. When ur trying to speed up it has a delay which has gotten me very close to 2 accidents. Shifting is also very rough, it kicks in hard. The dealer did a transmission update and the problem persists. Took it back again they scanned for codes and said they can't find any issue. I feel this car is dangerous and the transmission needs to be replaced before an accident occurs.

Please investigate acura on their 8 and 9 speed transmission. The transmission hesitates and jerks between shifts, is unresponsive to downshifts (unless it is in sport mode), reluctant to up shift at times, grinds at certain speeds and you can move the car a half foot in park. Most time, this is frustrating and upsetting for an upmarket vehicle, some times it is concerning as you feel you cannot control the car and could cause an accident. I have taken it back to acura 5 times and despite software updates and a "new" transmission, nothing has changed. I met with the acura mid-atlantic rep and he said this is the way the transmissions behave so honda can meet the government fuel economy requirements. I had a high-gear transmission before this car and never had these issues. I have read about the same problem on other sites and in car magazines yet honda/acura is doing nothing about it besides "software updates." this transmission, produced by zf and installed in other vehicles such as chrysler/fiat has the similar issues. What can be done about a product that is clearly faulty? Thank you.

My 2015 acura tlx hesitates when changing gears, does not accelerate when gas pedal is pushed and the shifting out of parking position is noisy and harsh. Acura has provided a defect code for my complaints (03214) and software updates (operation number 1255a2 and 1255c9), which have been performed on my vehicle. None of these have fixed the problem. Lemon law favored in the manufacturer's side and the arbitrators say it is not a nonconformity. Honda's lawyer says that I did not take it in enough times and that hesitation for a moment is not a concern. Acura says they would not change my car because they all drive the same and that I am just not used to driving a vehicle like this one. The biggest problem with the car is that as it comes to a stop at an intersection or traffic light, it lurches forward extremely harshly as if I was hit by another vehicle in the rear. This is so bad that I have been experiencing lower back pain and have to take pain killers at times. And of course, I have to take this into account every time I have to brake, in order to avoid an accident. You must know how frustrating it is to have to worry about this each and every time I am reaching a stop sign or traffic light.. The car does it sometimes and others it doesn't, so I have to try and predict how it is driving that particular day. This takes away from me the ability to control my car in an emergency situation.also, there was one time when I needed to make a left turn and my car felt as if it were in neutral, did not accelerate and then after a moment decided to drive forward. Thankfully no car was coming, if not it would have been an accident. I have to now make sure that cars are far enough so that if it does hesitate again I won't be putting my family and I at risk. I hate having to drive my vehicle because it is unpredictable and I feel very unsafe.

Can you please investigate the 2015 acura tlx with the 9sp transmission? There is unintended acceleration when slowing down, unanticipated surging, and unexpected hesitation when attempting to accelerate. This is a known issue within honda but there has been no recall or public fix from honda. I included the purchase date of the car but the above happens at various times.

I have a 2015 acura tlx 4cyl. It is a very nice looking car however there is something wrong with the transmission. I have taken it into the acura dealership and they have confirmed that there is something wrong however they are not sure what. All they tell me is that there are no codes coming up telling them what it is. They just tell me that everything is documented so if and when there is a recall I have proof that it has been ongoing. When you are stopped and then proceed to go the car will jerk and hesitate to shift to next gear. This can happen while you are driving also, if you have to brake and then start again. Its very upsetting I have owned acuras before, the acura tl and the acura integra, both cars had a high performance. This car not so much. When is acura going to do something about this?? There hasn't been just one episode this is an everyday occurrence.
