Attempted to accelerate with pedal while at freeway speeds and after canceling cruise control, vehicle does not accelerate, downshifts instantly to 2nd gear, multiple warning lights on dash, main display reads 'emissions system problem'. accelerator function returns but transmission is stuck in 2nd gear at freeway speeds and very high engine rpm. must make emergency stop on side of road and restart vehicle to remedy. check engine light and 'emissions system problem' warning remain for a day or two following an incident but vehicle drives ok. this issue has occurred on 4 separate occasions. took to acura dealer after 3rd incident and dealer reported no trouble found.
Vehicle acceleration is sluggish at stop and go. during highway speed, if transmission is in low cruising gear and you need to accelerate, transmission is sluggish. issues was corrected at dealer. dealer found 1 faulty transmission computer code. new symptoms after computer fix, over acceleration and harsh shift points. dealer advised to drive 500 mile after computer reflash. interior light do not dim after a few seconds. interior lights will not turn off regardless of locking vehicle. rear suspension has a 0.55 camber difference, vehicle has 26,765 miles. i asked dealership service to look at this issue. dealer never advised on issues.
Experience three different scenarios where the transmission either appears to shift into neutral or gears grinding. 1) shifting from park to drive, the vehicle all of a sudden stalls and engine revs up without any motion. resolved by shifting vehicle back to park, and then to drive. 2) when vehicle is in-motion at highway speeds between 40-70 mph, all of a sudden vehicle loses acceleration power and speed decreases for 3-4 seconds forcing other vehicles from behind to either brake or slow down. often occurs while merging onto the highway or lane changes where acceleration is required. 3) while driving on normal streets at 30-40 mph, gears grind for approximately 1-2 seconds without losing acceleration.
Before sharing the details, you should know that this could be a deadly safety matter. if a transmission fails at highway speeds (or any speed), the vehicle loses power and could very easily get crushed by an 18-wheeler. a driver and/or a whole family could die. you should go after acura before someone has to die as a result of acura's negligence. my 2016 acura mdx had its first transmission replacement in october 2016 at around 14,000 miles and about 18 months into ownership. i had purchased the vehicle as a brand new car from an acura dealer. i am the only owner, and it has been "babied" and received proper maintenance from acura dealer service shops only. leading up to the 1st transmission replacement, the vehicle was making awful "chirping" noises upon slight acceleration at slow speeds. after the 1st transmission replacement, all seemed fine until recently. at around 38,000 miles (spring 2019, still barely within the 4 year warranty), the vehicle began to exhibit identical symptoms. at 39,000 miles, the mdx received its 2nd transmission replacement. on the very day that ...
Purchased the car 7/6/2019 used with 26,943 miles. at 27,961 miles i was driving on the freeway in stop and go traffic. pressed on the accelerator after a stop and the car jerked and i heard a loud "clunk". warning lights appeared for "transmission system problem" and "blind spot warning malfunction". the car seemed to stay in first or second gear as i slowly exited the freeway at high rpm. had it towed to the acura dealer. transmission replaced as a result.
Three times while travelling on the interstate my vehicle suddenly shifted into second gear while i was trying to accelerate, and got stuck there. it suddenly dropped my speed from 70 mph to 30. i was presented with several alerts on my dash (emissions failure, sh-awd failure, transmission failure). i was able to continue driving at 30 mph until i could get to a safe area. after i turned off the vehicle and waited for a period of time the warnings would clear. i was finally able to get the vehicle to a dealership while the warnings were present. i was told after diagnosis that the transmission software needed to be updated. after the update the problem has not presented itself again. i was told software updates are not covered under warranty unless they are a recall issue.
Purchased a certified pre-owned acura mdx dec. 30, 2018. since owning the vehicle we have experienced 3 episodes of vehicle losing forward throttle while driving at highway speeds. 2 episodes occurred while attempting to pass another vehicle. it is as if the car goes into neutral. there are no error messages or engine shut off. within 10-15 seconds the transmission engages. after each incident we have brought the vehicle to our local acura dealership. p2638 code is generated with each incident. they cannot replicate the problem. they have updated the software and completed all the latest recalls. corporate has been notified and we have a case number. each time the vehicle has been returned to us telling us it is safe to drive. corporate refuses to help and assures us it is safe. the most recent episode may 19,2019 happened after the dealership had our vehicle for 2 weeks.
When slowing down at a yield or a right turn on a green light to about 5-10 mph and then when pushing on the gas pedal there is no acceleration. the car feels like it loses power and then after a second or two, the car will jerk and accelerate very quickly while reving the rpm very high. this has happened on numerous occasions and is extremely dangerous when making a right turn. there have been times where i make the turn and the car does not accelerate and then there are cars behind me that must swerve to avoid me.
While cruising at about 70mph on the interstate, i attempted to accelerate and the vehicle rpm would drop to about 1000 rpm and not allow me to control the acceleration. regardless of various attempts to accelerate the vehicle continue to lose mph. after 5-10 seconds, i was finally able to regain control of the vehicle. this has happen on about 6 occasions since i purchased the vehicle in 2015. i've attempted to have this issue resolved at the dealership service. on each occasion they stated a software fix would correct the problem but this continues. i've also had the issue occur while driving about 40mph on the city street. i was told by one dealership (the above incident occur while more than 500 miles from home)that this appears to be a transmission issue and that it would need to be replaced to resolve and would be covered by warranty, this dealership provided me a computer code from my vehicle. my current home dealership continues to state it is only a software issue, despite the fact that i had brought my vehicle in for maintenance 2-days prior to my trip and a software update was ...
Tl* the contact owns a 2016 acura mdx. when the vehicle accelerated after slowing down, the transmission slipped and the vehicle stalled several times when making turns. in addition, the vehicle made an abnormal chirping sound from the engine compartment, which distracted the driver. there were no warning indicators illuminated. the dealer had not been notified; however, the contact planned to take the vehicle to finlady acura (315 auto mall dr, henderson, nv 89014) for diagnostic testing. the manufacturer was made aware of the failures and did not assist. the failure mileage was 34,000.
Transmission has jerks and slips. these problems were addressed to dealership 4 times after purchase. first two visits they changed transmission software. each time transmission worked worse then before update. on 3 and 4th visit answer was - "this is acura's design". on jan 21 current year while trying to start from intersection turning to the right transmission lost any traction/torgue for 1-2 seconds after start moving. engine rpm went up to 6-7 rpm without any traction to the wheels. this almost led to the accident but truck driver moving straight was able to break in and change his trajectory. on jan 23d it happened again on stop sign when car refused to start for few seconds while engine rpm was in almost red zone. both happened on country road. these were the coldest winter days (less than -20 f) and transmission acted worse. all other time it "jerks" and "slips" intermittently during driving without crucial consequences so far. attached is service report from 2d visit to the service within first month of ownership.
We purchased our 2016 acura mdx new, back in 2016. starting in 2018, we began experiencing issues with the way the vehicle changed gears. when we attempted to accelerate, it would not. the tachometer would rev up, and then the gear would violently engage. we took it in multiple times to the dealership and were advised that they couldn't find anything wrong. on 1/8/19, while my wife was out of town, we experienced a "catastrophic failure" of the transmission, literally pour out transmission fluid and other mechanical parts of the transmission and leaving my wife stranded out of town. we were towed to the acura dealership in the area, and the transmission had to be completely replaced. we got the vehicle back about a week later only to discover that the same symptoms that eventually that led to the catastrophic failure are still on going. i took the vehicle in to the local acura dealership and met with the service manager who advised me that this is a known issue with the 9 speed transmission, and precisely why acura replaced this transmission with a ...
The vehicle shifted to neutral while driving at 70 mph and the dash started showing transmission and fuel system errors. the vehicle would not shift back to drive mode. after pulling over to the shoulder and turning the vehicle off and on the vehicle could not be put in drive. after about 30 minutes of repeatedly turning off and on the vehicle shifted to drive and was drive able. this could have lead to an accident if there were vehicles behind me.
When driving the suv after the second gear kicks in the transmission has a jolt and it feels like a lag in the shift but then pulls very hard. this shift pull happens when you are going 15-20 mph. engine timing belt has a loud chirping noise.
I recently bough the car and i am now regretting it because the 9 speed transmission is very sluggish and doesn't provide power when needed. in the morning when i start the car the car just lags the power until i press hard on the gas pedal. we took this on a road trip to california from utah and at times i feel like i don't have ample power to pass other drivers and it takes a few seconds to think before it does anything. i have an appt scheduled with acura tomorrow to see what can be done to fix this otherwise i am taking this suv back to the dealer for another car. i am very disappointed with acura for making this kind of a transmission and i wish i have kept my bmw.
