  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Well, I was getting a random "Check PSB" error message after the car warmed up after running for 10 minutes or so, which would blink quickly and then disappear and reappear repeatedly. This progressed until I noticed that while this was happening I was losing throttle response. I was getting no power when I pressed the gas pedal more than the tiniest bit. Finally decided to floor it while it was doing this to see if it would do anything. Sure enough, this triggered the traction control and auto hold to throw up error lights.

Took it to the dealer, they couldn't replicate the problem in the service drive, but upon connecting the car to the diagnostic computer found two error codes in the computer that controls the smart cruise, fuel pump, and seat belt pre-tensioners. They replaced the computer and had the car back to me in less than 5 hours. Coming from 20 years of BMW ownership, this is equivalent to parting the Red Sea. BMW would have kept the car for a week to diagnose, order the replacement computer, and program it to the car. Problem is thankfully gone.

Posting in case anyone ever has to search the forum for a "Check PSB" error message.
 
Thanks for this post. I'm new to the car and forum having just purchased a '15 3.8 HTrak. I bought it just off lease and for a great price for all of the car that you get. In the week that I've had it I'm more than impressed with the car technology. The ONLY gripe I have is I'm hearing a little more noise than I'd like from the front suspension. I've owned every German luxury and performance car there is, and purchased this car solely for affordability. I'm hoping that Hyundai can get this issue straightened out. I didn't get the drop in power that your did, but from reading other threads, I'm assuming it's the same issue as you had. Took it to Hyundai and they said they can't get me in until Monday morning, so I'll keep you posted. So it's back to the Lexus for the weekend.
