So I was cleaning out my garage and was getting ready to put my code reader up when I decided to see what information it could tell me about my GS. I didn't have any lights on the dash, but I threw 4 codes.

P0300- Random misfire detected
P0125- Insufficient coolant temp for closed loop fuel control
P0894- Transmission component slipping
P2714- Pressure conto solenoid "D" performance or stuck off

Should I be worried about any of these or do they sound worse than they really are?

 

Man you're having such bad luck with your car. First they repainted your bumper before taking delivery, and now this?? WTH with Lexus reliability nowadays.

 

Tell me about it... The bumper wasn't technically a Lexus reliability issue, more of a bad dealership repair, but I didn't expect this...

 

It's still in warranty. Take it back to the dealer and let them do what is necessary to clear the faults.

 

The check engine light isn't on and the car drives fine.

I bet there is a reasonable explanation and nothing is wrong. Any chance of false readings from the code reader? Do you have a good one?

 

My question would be how often does someone hook a code reader up to a car with no issues? Is it uncommon to find codes that aren't throwing an MIL? I don't know the answer to that.

Personally I wouldn't worry about it until the car gives you a reason to. Bring it up at your 5k.

 

I checked mine for codes a few times and found zero issues. U should not have any codes on ur car at all, that means there is something wrong with it. Recheck it again and if it still shows up then bring it in and have the dealer look at it.

My old Accord gave me a check engine light and some other lights show and when it pulled a code for Cyl 1 misfiring.

 

I had about half a dozen codes in after taking delivery of my new GS. No MIL so I reset and nothing has come in during the last 8 months and it was clean when it went in for it's 6 month checkup?

 

Just clear the codes and check back after couple days of driving for a few weeks after that. If you bring it to dealer they will just clear it and pretend nothing happened unless the MIL on.
