While driving on the freeway my engine started slowing down and a message came on the dash saying "Transmission Service". I was fortunate enough to make it to the right shoulder from the first lane and the engine stopped. The readout on the dash said I was in neutral but I was in park. The car wouldn't start. After cooling down I could start and drive but the same issue would happen intermittently. I took it to AAMCO and they told me that there was a recall for the range sensor and wiring harness (S55/NHTSA 16V-529). When I got to the dealer he said that recall didn't pertain to my vehicle and I would have to pay for the service. Since the issue does cover vehicles of my make, model and year I want to know why isn't it covered? It's the same issue as the ones covered. I'm lucky that I wasn't involved in an accident because of this.

ENGINE — Filed 06/03/2024

We purchased the van in April 2024, and the mileage was 130268. We checked the oil regularly and noticed the level dropping. After driving it 3080 miles and checked the oil level after letting the vehicle sit over night. The oil level was down almost 2 quarts. I contacted the dealer and told them what happened and they mentioned that there was a recall for some Promaster City vans. I looked up the information and found the recall marked as W80. I contacted Chrysler and they said our vehicle isnt listed and to contact the NHTSA. It has the same problems and is losing the oil in the same amounts as specified in the recall but for some reason, our VIN isnt listed in the recall.
