I own a 2007 Jeep Compass with about 80K mileage. I purchased it used a year ago and have replaced the starter 3 times now. I think the dealer is fixing the symptom (result) not the root cause. Luckily I have not had to pay for these repairs but it is still a pain.
Situation: Driving at highway speeds always in snowy / cold conditions; car will suddenly go into limp home mode and the ETC (electronic throttle control) light comes on. Once car is shut off and keyed on, the lights go away but car with not start. You do get a burnt electrical smell. Since it is a manual, the last two times, I pushed started the car and drove it back to the dealer without issue (no lights or performance issues). The dealer says he only replaces the starter and it works again.

Flash: DTC P2110 / Electronic Throttle Control (ETC) Lamp Flashes at Speeds Greater
Than 95 Miles Per Hour
This bulletin involves selectively erasing and reprogramming the Powertrain Control
NOTE: Vehicles equipped with a CVT transmission must have the transmission
control module (TCM) checked for the latest software level whenever the
PCM software is updated. If newer TCM software is available, it must be
installed. Failure to maintain software coordination may result in MIL
illumination or driveability concerns.

NOTE: This Bulletin applies to models equipped with a 2.4L engine & automatic
CVT2L (Off Road) transmission (Sales Code ED3 with DAW) built prior to
April 2, 2008 (MDH 0402XX).
Some customers may experience the electronic throttle control (ETC) lamp flashing in the
instrument panel if the vehicle is driven over 95 miles per hour. Vehicles equipped with a
CVT2L (Off Road) transmission are not designed to be driven at excess speeds. To
protect the transmission, vehicle systems will “torque limit” at speeds greater than 95 miles
per hour and will prevent the vehicle from going faster. The ETC lamp flashing may cause
customer concern, especially when the vehicle torque limits and prevents the vehicle from
NOTE: It is normal for vehicles equipped with a CVT2L transmission to torque limit
and prevent vehicle speeds above 95 MPH.
Further investigation by the technician may find DTC 2110 - Electronic Throttle Control -
Forced Limited RPM.
It is important that the customer understands the operating characteristics of the vehicle.
The software available with this Service Bulletin will eliminate ETC lamp flashing but will
not change the torque limits associated with vehicle operation.
