Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored.

If the valve body is worn, replacement will be necessary to correct this concern.
I've had an intermittent no-start condition on my 2000 Buick Park Ave. This started happening on occasion and was nerve racking. Took it to my local mechanic shop and he replaced the crankshaft position sensor which solved the problem. Found the problem with the sensor 'A'(18X24X) out of range. Code PO336-CKP. in the computer.

The leveling system air compressor head has a relief valve in it that corrodes and sticks over time. Each time the car is started, the compressor should cycle to pressurize the system and then the release pressure as needed to establish level.

at around 130,000 miles transmission began to slip when slowing and then accelerating rapidly. At 182,000 mi. Trans. Started making a growling sound, I had it replaced with a GM. Factory remanufactured unit for $ 3,200 still going strong at 225,00 mi..

Sometimes if I put my purse in the passenger seat, it triggers the seat belt alarm. Weight is about 2-3 lbs. The alarm will not turn off even if I move my purse to the floor. Must turn off the car, put purse in floor and then turn it back on. Dealer says that it is caused by my cell phone in my purse and that there is a bulletin out about this problem. The fix is to never put my purse in the passenger seat.
