Accord Touring 1.5t

  • CVT transmission
  • 43,600 miles


2018 Honda Accord Touring 1.5T 43,600 mi Driven by a 50 year old man, who drives it like a 60 year old man (maybe seen 3500RPM twice in its life)

Cold start misfire starts 6 months prior to taking vehicle into dealership.

Cold start progresses from subtle vibration to shaking over the course of 6 months, error messages for a misfire on cylinder 1 consistent for the last 30 days. Would hold idle RPM at 1900 to avoid limp mode.

Dealership diagnosis: 1. failed fuel injector on 2 and 4 2. scope detected coolant in cylinder 1.

Recommendation: 1. New injectors 2. Head gasket

Solution: New injectors and head gasket, all covered under the powertrain warranty.

Total time: 12/27/23 -- 01/05/24

Dealership experience: outstanding

Honda reputation: took a big hit for me, head gasket AND injectors at 4.5 years/ 43,000 miles? Cmon!

Accord Touring 1.5L

  • Automatic transmission
  • 78,000 miles

2018 Honda accord touring model with blown head gasket at 90,000 miles- always owned Toyota brand cars never did I think I would have this issue on car of this caliber. It's obvious there is an issue with this engine with all the complaint's.

Accord Sport 1.5L

  • Manual transmission
  • 91,000 miles

First noticed gurgling sounds from engine. Then had engine overheat due to low coolant. Then noticed misfire on acceleration. Brought to dealer who diagnosed head gasket and turbocharger problems. Wanted to charge me $5500 to fix. I took to local independent Honda specialist who machined head and replaced head gasket for $1500, No turbo needed. Dealer was a ripoff. Disappointed in a 90k mileage Honda head gasket replacement. I'm wondering how prevalent this is.

Accord LX 1.5t

  • CVT transmission
  • 59,928 miles

2018 Honda Accord LX w/1.5 turbo engine began shuddering at startup on Oct-8-2022 w/59,928 miles on it. All kinds of error/warning messages displayed on dashboard. The shuddering started prior to this date but quickly resolves in a few minutes of running so I thought no big deal just needs to warm up a bit. Car runs smoothly once warmed.

On that date, car seemed to be running fine once warmed up for a few minutes so I thought maybe a computer/electronic glitch. I parked and turned off the car. Started it back up and all the errors/warnings were still there. I was an hour away from home late at night and the car seemed fine so I traveled home. Next day, I read a DTC P0301 misfire code and then cleared the code. Car ran fine until Nov-29-2022. When codes reappeared. Made service appointment for Dec-1-2022. Dealer informed me that head gasket blown, >$4000 repair! Ridiculous for a new car w/60k miles. This is a design flaw on the earth dreams 1.5 liter turbo engine.

Accord LX 1.5L Turbo

  • CVT transmission
  • 94,000 miles

This car has been nothing but a nightmare since about 30,000 miles. At about 35,000 miles, I noticed that the car was burning oil. As I monitored this, it began to significantly burn more and more, over 3 quarts between 5,000 mile oil change intervals. I brought it to 3 different Honda dealers and all of them told me it was normal. So I continued to drive it and just add as needed.

At about 80k miles, the car developed a misfire at startup, almost every startup. The misfires were happening in cylinders number 1 and 2. At about 85k miles (2 weeks later), I got stuck on the side of the road with the car, due to it overheating. I popped the hood to find no coolant in the overflow bottle. I bled the entire system that night and filled it with fresh Honda antifreeze. A week later it overheated again and was empty on coolant again. I repeated the process and continued to drive it.

Now with 93k miles, the car seemed very hesitant and powerless while I drove. It then overheated again. I took it back to the dealer at this point, Eatontown Honda in Eatontown New Jersey, and they confirmed that the head gasket was blown and that I would have to pay $17,000 to replace the engine. The car is 2 years old with a perfect maintenance history.

This is the last time I will ever drive a Honda in my life time. Honda corporate also refuses to take responsibility for their failed product. It is completely stock and unmolested. Worst car experience I will probably ever have. Unbelievable product, and even worse customer service from corporate.
