front and side engine mounts |
| 153000 mi US $200 |
mufflers, resonator |
| 122700 mi US $10 |
Repaired leaking emission control hoses by clamping them. They come from the factory only with a compression fit. As the hose hardens with age, it will allow air in, causing a Malfunction Illumination Lamp (MIL) lamp to illuminate showing a leaking gas cap. Sometimes the cap is the problem, but sometimes the problem at the emission control hoses, especially near the engine (due to the heat). |
| 124300 mi US $60 |
Rough idle. Replaced plugs to try to remedy. Recommended maintenance at 110,000. Didn't affect idle quality. |

City Mileage dropped from 19 mpg to 15 mpg. Removed and cleaned EGR valve twice. Mileage returned to 19-20 mpg. Also ran a bottle of fuel injector cleaner which seemed to help. Cost is for the two cans of carburetor cleaner. |
| 128120 mi C $300 |
Transmission fluid was leaking from rad core. Transmission cooler was integrated into radiator, replaced the entire unit. |
| 151900 mi C $10 |
There was leak underneath the engine. Found that oil gaskets (there are few) leak for high mile cars. So all the gaskets around the timing belt area were replaced. pan gasket replaced, brakes. There was a loud noise one day from underneath the car. Checked and found that there was a gap between mid catalytic converter and the rear exhaust pipe. The bolts were rusted around that area. So ended up buying bolts and a new gasket. |

| 225000 mi US $90 |
broken front motor mount. replaced |
| 284000 mi US $12 |
Seafoam cleaned throttle body/ top end. I'm getting a vibration either on throttle tip in or sometimes at steady state on level roads. No codes. Dealer & another Master mechanic suggested BG or SF intake/throttle body/top end cleaning. SeaFoam helped a lot, but it's still not all the way gone. |

| 134000 mi US $400 |
Front engine mount was broken whereas the right engine mount was rotting. I could've waited an additional 10K-20K but didn't want any catastrophic failure of the third and final engine mount nor the 2 mounts for the transmission. Oil pan bolt and pan threads were stripped...:( It's made out of aluminum so make sure a new crush washer is always applied with each oil change and make sure they don't over tighten it! |
| 115000 mi US $1000 |
Cost prohibitive repair to have the dealer remove and replace the right front axle exhaust heatshield. But the rattle is driving me outta my mind. |
| 78000 mi US $600 |
2 engine mounts are cracked. The mechanic said this is common among the larger honda/acura vehicles. They put larger engines in, but this puts additional stress on the engine mounts. |
| 114000 mi US $800 |
Engine Light and VTM-4 light. Codes showed many misfires. Needed valve adjustment and EFI service |

CEL indicated fuel tank pressure problem - but not loose gas cap. Techs found no failed parts but blew out lines going to evaporative emissions controls. Problem did not return. Previously I had cleared the CEL and problem did return, so detaching, blo |
| 43000 mi | Same fuel tank pressure code thrown. Tech blew out lines again, but claimed that this time debris came out of lines. Covered under warranty, and will be again if it recurs. |

The intake / exhaust valves needed adjustment due to cylinder misfires triping the CEL. |
| 47000 mi US $17 |
DMV said gas cap failed emissions. Pretty sure the tech purposely failed the cap to meet a quota, as cap is tested each cycle by the vehicle's OBD-2 diag. Anyway, failure requires a repair, so cap was needlessly replaced. Cap not stocked at any dealer.. |
| 80100 mi US $150 |
Valve Lash required adjustment. Attempted self repair. Didn't break anything and it's better, but not perfect. Need to try again. |
| 87000 mi | Motor mounted had failed and were source of clunking on acceleration. Valve lash adjustment performed by dealer (following earlier self-repair attempt). Getting the feel just right is difficult. Dealer was better but still not perfect. |
