Is this a common problem? With only 37,000 miles on the car should these parts be failing? Anyone else experiencing this expensive issue?
Air Pump #P2234
Air Ride OEM Sensor #8W1Z-5359-A

Thanks

MY engine light came on right after an oil change. I took my car back and they told me and showed me 4 "spark plug" like things under my car and told me I had 4 oxygen sensors that were not functional on the diagnostic test, so they replaced them charging $129 each $240 in labor.

the fuse for the dome light blows if the fuse does not blow the battery discharges

Certain vehicles are being recalled because the upper intermediate steering shaft could separate resulting in loss of steering control. This recall includes models previously recalled under campaign #13V-385, these vehicles may have been incorrectly repaired. Dealers will inspect and replace the upper immediate shaft if necessary. If the steering column lower bearing has separated, a retainer clip will be installed.

The intermediate shafts connect the steering column to the steering gear. Vehicles in areas where salt is used to de-ice the roads are being recalled because severe corrosion can damage the lower intermediate steering shaft. This can cause the upper intermediate shaft to collapse and separate at the lower steering column bearing. Separation will result in complete loss of steering ability. Dealers will replace the lower intermediate steering shaft and inspect the upper intermediate shaft and steering column lower bearing for damage, they will be repaired or replaced as necessary. If the steering column lower bearing has separated, a retainer clip will be installed.

Additionally, Vehicle owners located where salt is not used who have concerns regarding their steering will have a one-time option to have their vehicles inspected and, if necessary, repaired.
