general problems of the 2012 Acura MDX

See attached document for complaint.

On 11/30/24 I heard a slight whirling sound while driving. On 12/1/24 I drove from point a towards my home. Along the way the oil light flashed. I stopped at advance auto parts, 15 miles from point a. I checked the oil and it read as it should on the dip stick. No oil was needed. I drove straight home, a distance of 30 miles, and parked the car. When my son arrived home he started the car and there was a knocking sound. He shut it off. He stated that he felt it to be the rod bearings. He then changed the oil as previously planned as supplies were already in the car. He checked the oil and found a slight glitter in it indicating the rod bearing issue. The car remained parked until 12/26/24 when it was taken to an independent service center, round trip of 18 miles, who confirmed that the rod bearings were the issue. The car was parked again and only started to move about 50 feet into the garage prior to a snow storm. It has not been started since. My safety was put at risk as the engine could have, and will, fail when driving. The engine had previously been repaired at an Acura dealer for an oil consumption issue in accordance with service bulletin 19-006. Honda refused to honor the recall previously offered due to this known failure. The car was picked up on 12/8/22 with 92,954 and purchased finalized on 1/4/23. The oil consumption issue was first noted on 2/12/23 at 97,088 miles. Car was serviced and oil changed on 2/16/23 at which time the oil consumption issue was diagnosed by the selling dealer. Oil was continually added until work was completed on 3/21/23 at 99,425 miles. The new issue with the rod bearings (that were not changed with the first repair as they should have been) was first noted at approximately 137,840 miles. This is now the second engine failure for this car. The car is available for inspection. The car has not been inspected by any entity other than the initial diagnosis on 12/26/24.

Oil consumption/burning cylinder rings.

Done everything dealer suggested and still having problems with random misfires in 1,2 and 3 cylinders, changed spark plugs, fuel injectors, ignition coils and compression test and changed rear cat. Still check engine light come on sometime then the SUV driving good, and sometimes it drive ruff, check engine light come on then go off then come back on with same codes: random misfire.

My 2012 Mdx model is consuming excessive motor oil, after 3000 miles driving , I'm down to 1 1/4 quarts. The test was done and oil changed on two occasions on 3k miles and 2k miles . All this is happened during 8 month of the my ownership.

After driving the vehicle, I parked it, turned it off and it caught on fire.

S25 s25 recall fuel system 2012 campaign number 12v063000.

Acura Mdx 2012 - persistent slow start of the engine; engine is straining to turn over/start. I have replaced the battery 4 times, checked all possible problems (starter, spark plugs etc. ) but same random, periodic problem of the engine struggling to start. Related problem: fuel tank appears to be somewhat loose; when I buy gasoline, I can see the gas tank move. In addition, it is difficult to fill up the car with gas; the gas pump cuts off before the gas tank is to the "full" level. My gut tells me that these 2 problems are somehow affecting my car starting. My car has only 51,000 miles on it. I take good care/maintain it. I have read others complaining about the same problem!!! Acura should fix this! too expensive of a car; where is the quality??? this is an ongoing problem of my 2012 Acura Mdx . Please help.

This vehicle unrealistically burns oil. 5-6 quarts of oil is added to engine between oil changes.

The car uses excessive engine oil. I have to add at least two quarters of oil between oil change.

Consistently getting low oil notification shortly after getting oil changes. This has been happening since 2017. Dealer does a oil consumption test and says it is not a problem. However I cannot go between oil changes without getting the notification. I have no oil leaks. Furthermore, I have had 'oil' services done over the past 5 years that never fix the problem. I'm afraid this is doing damage to the vehicle and can put us in danger if oil level is too low. Dealer continues to say it isn't a problem. And when they try to fix it, it doesn't work. This began in 2017.

The engine consistently consumes too much oil between service events. The low oil light comes on. I had this problem for over 8 years and the dealership said it was not a problem until now and they want me to pay for it. The oil control rings have been clogged since 2016 and progressively gotten worse. The clogged rings cause restriction of oil to return to the crankcase. This causes a decrease in available oil and may cause overheating that could lead to engine fire. Acura should fix the oil control rings to function properly. They have identified this in the past, through a service bulletin (19-006). I have performed 97% of my oil changes at Acura dealerships.

When I am driving on the high at high speeds 80 mph then I go to get off an exit the steering wheel vehicle shakes and vibrates the front of the car and tires.
