2017 Acura MDX engine complaints
Page 4 of 4: complaints 71 to 97 of 97, newest first, as owners wrote them.
The contact owns a 2017 Acura MDX. The contact stated that while his wife was driving at an undisclosed speed, she heard an abnormal knocking sound coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the connecting rod bearing, resulting in damage to the engine. The vehicle was not repaired. After investigating the failure, the contact related the failure to the federal safety agency Campaign Number: 23V751000 (Engine and Engine Cooling) but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 110,000.
All lights lit up on dashboard with no previous sounds, knocking, or issues. Upon getting the vehicle towed, the dealership said that the CAM Shaft and sensor needs to be replaced. Which is approximately a 4K dollar repair. Upon further inspection. The dealership showed me a copy of a 2018 notice where this was a known issue with a specific code of C0369 where it states that there should be no repairs but only replacment of the complete unit and that the machining of this part is know to have substandard machining spec issues which will cause the shaft to erode. This vehicle only has 67,589 miles on it. (which is out of warranty by 6800 miles.) All of the information that I have investigated states that the only way a CAM shaft goes bad is insufficient lubrication, improper break-in, reusing old/worn components, mechanical interferences, and inferior hardware/hardware not torqued to spec. I beleive this issue needs to be further investigated especially since there is also the new recall which states the crank shaft rod bearing was also failing due to the original machining was out of spec. In addidtion, if this was a known issue withthe CAM Shaft since 2018, why was I not notified and why is this not a recall? The dealership currently has 3 other cars in its service area with the same known issue. Of note, this vehicle was running fine when it was parked and upon starting the car and going approximately 5 mile per hour, all warning lights lit up and said to place the car in park. No other prior warnings or issues to speak of other than stalling when stopped at a red light.
The contact owns a 2017 Acura MDX. The contact stated that on several occasions while driving at various speeds the vehicle lost power. The vehicle was taken to a dealer where it was diagnosed that the clutch and gear needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 40,000.
Great hesitation, in acceleration, clicking of gears and drive and while putting in reverse also clicking of the years when accelerating
While driving at freeway speed, fourth lane from the right, the vehicle became unresponsive to the gas pedal input and started to glide. I managed to get the vehicle to a narrow shoulder on the right before coming to a complete stop. I had one of my grand child in the car seat as a passenger at this time and I was very concerned about stalling in traffic and getting rear ended.
On Friday May 5th, 2023 myson was driving our 2017 Acura MDX in heavy rush hour traffic on Interstate 355 near Homer Glen when suddenly and without warning the transmission failed and caused sudden deacceleration. He drove the car which was going 7 mph and engine revving and starting to clatter to get off the freeway. The check engine light came on. He called and informed me while on the exit ramp. I instructed him to pull into the Gas N Wash filling station at 15930 W 159th and shut the engine off, I left home immediately and upon arrival I looked under the hood for oil leakage or low level and belts broken. When I started the motor a knocking sound caused me to turn it off. This could have caused an accident due to heavy traffic at 70 MPH posted speed limit. The car has been towed to local mechanic shop for diagnosis. My online research indicates a Class Action Suit and countless complaints of similar unsafe operation and transmission failure. We purchased this Vehicle new in 2017 from Rizza Acura, Orland Park, IL and have had regular maintenance performed since purchase date.
I was on the feeder road of a major freeway in Houston Texas at a stop the brake fully applied. The auto engine idle stop was enabled. When I removed my foot from the brake the engine did not restart. The lights, radio remained on but I was unable to drive my car or change the gear shift. Being on a freeway feeder was a dangerous place to be stalled and had to wait in major traffic for a tow truck to come as the vehicle could not be started or turned off. Completely inoperable. The check engine light was on and oil light. I was towed to a nearby maintenance shop where a p2638 code was listed. After the car was towed the car would restart. Prior to the incident there have been other occasions where the vehicle struggles to restart the engine from the auto idle. However there were no warning lights. Additionally I scheduled service with the dealership the next day and they show an auto idle recall as an item for repair. There is no recall listed on the federal safety agency. Additionally I see a class action lawsuit was filed earlier this week for a potential ongoing, long term issue related to this product.
Driving down the freeway cruising around 70 miles per hour when the multiple sensors tripped and car started to slow down to 50 mph. Took the exit and when I came to a stop the car was moving very slow. Had to go over an overpass and it barely made it over. Close to home so drove the car slowly. The car at times would stop moving and took a little time for it to pick up and started moving slowly again. The sensors that showed were the electric parking brake problem, emissions system problem, transmission system problem, blind spot info system problem. Had I not been close to home or no exit near, my car would have kept slowing down on the freeway. Family car and I also had my kids with me.
The auto engine disable function causes the car to stall unexpectedly. The car engine stops, and the car changes from Drive into Neutral. The only way to re-engage the engine is to place into Park and restart the car. Sometimes, it requires more than one attempt. Fortunately, this has only happened while the car has been stopped, but it has happened at several busy intersections, holding up traffic and creating a safety risk for me and others. Reading online, this is a known issue with suggestions to report this to the federal safety agency to include in the overall tracking. Hoping for a fix before someone crashes into my stalled car. I listed the last known date, but this happens with frequency (about 1x/week).
The vehicle stalls and loses all power when coming out of auto idle stop. This is a default feature that shuts the engine off when the vehicle stops to create fuel efficiency. But it is creating a terrible safety issue of having vehicles unexpectedly stopped on the roadway. The feature cannot be permanently turned off. Common issue on MDX forums without any real solution from dealership mechanics.
On multiple occasions (6 times within a week) the powertrain loses power. While traveling 60 mph in 4 lane Interstate traffic engine loses all power and accelerator ceases to respond. Passengers were at risk due to no power. Acura Dealer has not been able reproduce. Some dealers have affirmed that they've had customers with the issue but can't reproduce. The issue seems to occur more frequently after cruise control has been dis-engaged. I have spoken with another a 2018 Acura owner directly and they have experienced the same issue. It does seem the engine/powertrain resolves when the transmission is switched from "Normal" to "Sport" mode. The amount of time with loss of power seems to span about 5-10 seconds.
While driving suddenly all error warnings came up. It included Check Engine Light, Error messages included: Electronic Braking System error, Emission System error. The light indicative of parking P! kept blinking also the (P) came up on the dashboard. Interestingly after some time this all cleared on its own. Then came back again only this time it stayed on. I don't know if this has compromised the safety features of the vehicle including emergency braking (crash avoidance/vehicle proximity)
We were driving on the highway yesterday at 75 mph when suddenly our tachometer jumped a couple of times and then the car lost all power and switched into neutral. It's the same transmission problem others are reporting and dangerous.
Tl* the contact owns a 2017 acura mdx. The contact stated that while driving at 45 MPH, the vehicle stalled as the emission and parking brake warning lights illuminated on the instrument panel. The contact stated that after experiencing the failure, the vehicle resumed normal operation as the warning remained illuminated on the instrument panel. The contact then took the vehicle to lindsay acura (5880 scarborough blvd, columbus, oh 43232) where they were unable to duplicate or diagnose the failure. The mechanic cleared the warning lights off the instrument panel. The contact stated that the failure persisted soon after the return of the vehicle. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.
Loses power and unable to accelerate while driving at higher speeds. Has happened 4 times in 2 months
I own a 2017 acura mdx. When accelerating from a stop it hesitates for a second or two and then jerks when it finds its gear. This happens every time the vehicle is used. Merging onto the interstate or switching lanes can be very dangerous.
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.
Mechanical fire
Tl* the contact owns a 2017 acura mdx. The contact stated that the vehicle did not start when the push start button was depressed. After 45 minutes, the vehicle started. The contact also stated that the failure occured sporadically for approximately six months. The vehicle was taken to acura of thousand oaks (3945 auto mall dr, thousand oaks, ca 91362) four times, but they were not able to replicate the failre. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 25,000.
Car caught on fire while we were driving with all the family inside
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?????????
