Issues have now occurred twice within an approximately 4 week period. First time was near the end of June and the second time occurred on 7/30/20. After stopping on the highway, once for a stoplight and the other time to turn off highway onto another road, the engine stalled/turned off. After vehicle was back in park, I was able to restart the vehicle each time.

Car caught on fire while we were driving with all the family inside

- Frisco, TX, USA

I have been complaining for two years that my car intermittently hesitates when accelerating. I have pulled out into traffic and my car has hesitated long enough that I've almost got slammed in the back by another car. The car feels like it is about to stall. I will press the gas pedal down to the floor and finally the car starts moving again. Brought the car in on several occasions to Acura and since they could not reproduce the hesitation, they decided there was nothing wrong with the car. Another issue I've had is with my brakes. At 13,000 miles both of my front brakes were worn down to the metal. When I brought the car in, it was noted that both calipers seized. The brakes and calipers were replaced. About 14,000 miles later, my right front brake was down to the metal. My left front brake was fine. After keeping my car for a week and consulting with the engineers in California, Acura decided there was nothing wrong with the brakes and that it was my driving. I asked how I only put the right front brake on and not the left. They did not have an answer. But because they couldn't find anything wrong, I had to replace both brakes again.

Dangerous loss of power while accelerating on the highway! there have been three separate incidences over the last 2 years. While I was trying to accelerate on the highway, the car severely lost power and the "check engine" light started flashing. The car seemed to operate normally after turning off and on the engine. The dealership claimed that there was no computer records of problems after each incidence. Acura just issued a recall of the fuel pump on this model year MDX. However, Acura and the local Acura dealership refused the repair due to the lack of computer record of failure.

Yesterday while stopped a light, the MDX refused to move once I took my foot off the break. The engine became very loud and 'emissions system problem' and 'brake parking problem' appeared on the dashboard. The trunk opened but wdnt close automatically. I had to have the vehicle towed to the dealer. The vehicle had issues staying in neutral and would immediately revert back to park. The towing company had me continuously hold it in neutral in order to get it on the flat bed. It took 45 mins to finally get the vehicle on the bed. I was really annoyed as I've never experienced anything as such with my prior MDX and was on the way to meet my children. When we arrived at the dealer, a tlx was towed and had the same issues. The vehicle shut down and wdnt move like mine. Thank god I was not on the highway. I have complained about the shifting of gears when driving and was told it was normal and the vehicle would eventually change but it's also still happening. Needless to say I am very dissatisfied and disappointed and will not purchase another Acura

We have experienced many issues with our 2017 MDX sh-AWD. On a cold start when shifting from first to second gear there is a sudden lurch hard shift. Once warm this is still present but not as pronounced. The transmission seems to slip through gears and have sudden downshifts that decelerate the car or the vehicle will lurch forward without having your foot on the gas as it shifts itself into a different gear. When trying to 'punch it' and accelerate quickly it will often hesitate to go into the correct gear then suddenly rev high as it speeds up. Hunting up and down through gears while staying at a constant speed. The navigation system is extremely slow to come up and respond to inputs when the car is started. Acura has claimed this is due to cell phone bluetooth interference. Collision mitigation system has engaged twice. The first time by husband was in a parkinglot driving through a row looking for a spot to park. The car slammed on the breaks with no cars in his path and nearly caused the car behind him to rear end him. The second time I was approaching a stop light to turn right, there was a vehichle in front of me but the distance I was stoping from the rear of that vehichle was not an abnormal or alarming distance. The brakes locked up with lights flashing on the dash and an awful grinding noise coming from beneath the car. On one occasion from a parked position it would not allow us to engage it in drive. It flashed "shift to park" on the dash. It took three attempts to get it to go in to drive. The rear hatch hydrolics had to be replaced within the first 6 months as the power liftgate stopped working. One of the two key fobs also went out on us in the first 6 months, replacing the battery did nothing and the whole fob needed to be replaced.

On several occasions as I reduce speed, the car suddenly accelerates when I release the break to start accelerating again. The acceleration happen when you are going at slow speed. The first time I took it to the dealership it had happened in 4 occasions and I had atributed the incident to lack of experience in driving a new car. Because it happened in front of my daughters school ' and in theory I could have actually killed a child ' I promptly deliver it to the dealership. During the test drive with the technician, the car changed gears from the comfort mode to sport mode on its own. Because it was a safety issue, they informed me that an engineer from Acura would come and inspect the unit. After a week with my car, they just did an update into the transmission software - and informed me they were unable to recreate the issue. Thirty three days later' while dropping my dad at his dialysis ' at a turn - the car went form 3 miles to 25 miles, and it was fortunate that it was 5:45 in the morning ' since I could certainly would have cause an accident considering I almost ran a light. I called the dealership and on February 1, dropped again the vehicle at the dealership. 11 days later I called back to follow up and was informed by the service manager that Acura should have contacted me on Friday February 9 to let me know that they would be sending an engineer to check the vehicle again. Our concern is that this is a safety issue documented on two previous complaints in this forum, that constitute a serious risk for my family and community. At 11:00 am on February 12 I have yet to hear from Acura although they are aware of the issue.

We own a 2017 Acura MDX, my wife was driving the SUV attempting to park when the vehicle briefly accelerated. I was driving the SUV at low speed when it briefly accelerated, I was kind of stunned, and asked did you feel that, she said yes, and then stated I guess I wasn't imaging it when it happened to me, these were separate issues at different times and dates. The vehicle was brought in for service and this issue was mentioned, the service writer explained that Acura is aware of this and it's an intermittent issue and Acura has no fix, it was asked why Acura hasn't warned owners of the potential problem and the service writer explained it's a intermittent issue that hasn't been replicated in service and doesn't happen to all the vehicles. We asked doesn't someone think it's a safety issue, that when I was driving in laconia nh bike week it could have accelerated into a motorcycle or pedestrian. There was no response other than please rate us good on the service call what we did not what Acura isn't doing"???????"
