Aloha,

So I just just bought a 2006 Gs430. Currently it is showing all the warning lights on the cluster, hard start up and if driven to long long it loses power. Anyone had this issue before??

 

it could be so many things….

disconnect the negative on your battery then after, go and hit the brake pedal (dislodges all residual energy). Wait 15 mins and reconnect the battery and see if anything changes.

if lights still on then get the codes scanned to figure out what it is.

 

Sounds like a charging issue! But whats common is when these cars sit not driven they do throw a lot of engine codes. So if the car starts and drives, and doesnt drain the battery just drive it and usually a day they magically fix themselves.

If the problem doesnt go away, then I would grab a voltmeter and run test on the battery terminals with the engine running. You want to see mid 13 volts charging steady while at idle.
