2018 Honda Accord acceleration problems

Filed Aug 10, 2026 · Acceleration, Electrical · CA

While driving, my vehicle began shaking/rough running and the check-engine light came on. Multiple warning lights and system warnings appeared on the dashboard, including the brake system, steering, traction control, and TPMS warnings. The vehicle experienced noticeable shaking and reduced/abnormal performance. I am concerned that this may be a safety-related defect because multiple vehicle systems are being affected.

The gas pedal failed to work on three separate occasions. The car essentially went into “limp” mode where the whole car stop driving out of nowhere. These models of Honda are known for the head gasket prematurely going out which has caused me car to have multiple misfires, warning lights, loss of power. The problem has been confirmed by the dealership and an independent mechanic.

When Tpms light comes on, all safety features including cruise control become disabled. Lane assist and collision safety features become disabled. On top of that, I have had Honda look at my rear end after they replaced a rear upper control arm after being in a ditch and at 246,000 current miles, I have replaced my tires 16 times due to the rear tires ripping the tread off between 10-15k. If there was nothing else wrong, why have I spent between $10,000-$15,000 miles on tires? I have had numerous alignments at Honda and elsewhere. Marion Honda claims it’s normal! I was told I can put adjustable control arms on. I have met other Honda accord sport 1.5t owners with 50k miles on one set of tires, yet I can’t get more than 15k on the rear tires. Clearly something is bent or incorrect currently I am re replacing the upper control arm.. They say the alignment rack does not flag anything. I have bought between Goodyear, Michelin, and Pirelli tires they also replaced a turbo, only for a few months later to have a pressure problem that Findlay Honda found I was missing an oring in the turbo or intercooler. How? Orings do not call out. Fast forward 18 months and another bad turbo on this lemon!

I started driving this vehicle and all of a sudden it started slowing down, and would not go up to speed. I had it fixed, the car started skipping, making a jerking movement while driving. I made an appointment with Tameron Honda of Birmingham on 3/26/26. As soon as I pulled up to Honda dealership the engine light was on. The company was trying to bill me 6100 dollars for fixing the car. I do not have that amount on hand and I need my car. I had to drive my car away from the dealership while it was in idle mode state into traffic the car moved so slowly that I could have wrecked. The dealership did not do their due diligence by going off of the vin number and making sure that the customer is safe with their brand. I was told that they did a full inspection at the dealership. I have been scared to drive this vehicle since the issue keeps happening.

I took my accord into Snellville GA Honda dealer for fuel pump recall and the day I received it from the service department, it started to sputtter and engine shutdown. I took back 3 times and got a different answer each time. I believe the turbo charger may have been affected from the fuel pump being bad. The latest diagnostic says it has turbo under boost issue.

After recent service from local honda dealership vehicle started to drive sluggish. Had all fluids changed and the coolant flushed when serviced at the dealership. The vehicle now displays several different alerts upon start up "Emissions systems failure" Brake system failure" Hill Assist failure" Power Steering failure". Vehicle was returned to dealership and it was determined the head gaskets need to be replaced due to coolant leaking. This vehicle has been maintained consistently with documentation and shouldn't have this type of failure with only 100k miles. Repairs are $4800 and this should definitely be investigated because this is common in Honda Accord model years 2018-2022.

There are many warming lamps on in the car. My car won't pick up speed it in limp mode once I crank up. I have to turn it off and restart any order for it to go and pick up speed. My number 3 plug keep showing something wrong it has been replaced multiple times but still having the same issue. I had it checked out it's saying the same problem fuel. I have had my fuel pump change and still having problems. 2018 are bad models for honda and there should be multiple recalls because everyone having the same problems. Head gaskets,fuel injection, turbo problems as well as fuel pump

My fiance has a 2018 Honda Accord Sport Touring, this past Sunday he was giving me a ride and about 5 min of driving , after stopping for a red light , the light turned green he pushed the pedal and the car starting moving then all of a sudden warning lights were flashing , the engine light , remote not in car, oil light, air bag , low tire, etc. there was alot at the same time when the warning lights came on as he pushed the gas pedal the car stopped accelerating, and he said he had no power in the pedal ,there was heavy traffic, a car could of rear ended us but he was able to put his hazards on and coast around the corner before the car stopped. He shut the car off and back on and it drove like normal again. I was scared of course and just wanted to go home. When we got home he remembered he still had his fathers Obd scanner tool so he plugged it in the car and it showed no error codes. So that was really strange. He went to the store down the street the next day, but other then that he drives his work van and I have my own car. I was reading newsbreak and seen that honda recalled only hybrid and newer years and thought thats odd I should let someone know this happen to his 2018 accord , because Im sure it has to happen to others. We didnt take it in or call the police , but this clearly could of caused a crash had he not remained calm and put his flashers, everything happened so fast. Im sure he would let you inspect it, he works during the morning. I have no clue why it did that and neither does he. Thank you for your time.
