vehicle ecm keeps reporting an error code p2138 that refers to a correlation issue between sensors on the throttle/pedal system, causing the vehicle to enter into reduced power and eventually disables engine. Problem persists even after replacing pedal component. Apparently water enters the compartment where the part is located and corrodes wiring between the ecm and the pedal system. GM is apparently aware but so far has done nothing. Problem is especially hazardous because engine power is reduced during acceleration and happens without warning. Vehicle could be in high density traffic and then suddenly experiences lack of power or total disability, and driver must try to navigate to the side of the road--not always possible or safe to do.

Tl* the contact owns a 2009 chevrolet hhr. The contact noticed water leaking from the roof of the vehicle each time it rained.

Water leaking in passenger floor board only when rain
On 3 different occasions it has rained while my car sat overnight and water has seeped in the passenger side compartment from behind the glove box , I have had this addressed 3 times and repaired 3 times and found out that it is a small flap that covers a hole on the firewall that fails or falls off making it so that water enters the vehicle. This is not a isolated incident other hhr owners say they have the same problem.
Tl* the contact owns a 2011 chevrolet hhr. The contact noticed a leak of hot air/liquid under the dashboard coming from the front and rear of the vehicle. The contact was burned from the hot water leakage. The contact also stated that the vehicle made an abnormal swoosh noise when making turns, which created a hot mist inside the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 132,000.
The car has had the A/C fan motor replaced at least 4 times, each time it was damaged by a water leak. The dealership replaced motor once while under warranty but stated they could not find/fix the leak. This was a lie because it is a common problem with the butyl patch, easily found in the most basic internet search. The door handles are made of the cheapest plastic, driver's side interior door handle broke off. There is water leaking into the rear driver's side floorboard with no cause yet found. The worst part of this is the chevrolet dealership where I purchased the vehicle not completely fixing the leak problem during the warranty period, then charging me to fix it again after the warranty had expired. Now I can't even get them to return my phone calls regarding the recall repairs they are required to do.
