I bought an 2006 Buick Lucerne CXL several months ago. AND THE CAR RUNS FINE.
The current mileage is about 65,000.
Shortly after buying it, the low tire light came on. And yes it could have a tire problem.
I took it to my GM dealer, and ask if they could tell me which tire was at fault?
They put the Tech2 on it, and found no tire codes.
However they found approximately 30 other codes in the body control module.
These codes have been cleared several times, but keep returning.
And I recently had them replace the body control module. I put about 600 miles on the car and rescanned it. And the codes are back.
But some codes keep changing, as I have doccumented the past codes.
The body control module is divided into 15 parts, and these are the most recent codes.
1 Body and rear end - U0214
2 Cellular communications - OK
3 Cruse Control - P1629
4 Doors - U0208
5 Entertainment - U0198
6 Horns - U0214
7 Instrument panel - P1629
8 Keyless entry - P1629
9 lighting - U0214
10 Personalization - OK
11 Seats - OK
12 Stationary windows - U0214
13 Theft deterrent - P1629
14 Wipers / Washer systems - U0214
15 Rear parking assist - U0073
Any help would be appreciated, as my local GM dealer is also not sure what the problem is.
THERE ARE NO DRIVABILITY ISSUES I AM AWARE OF.
